To better guide the sustainable developing of freight transport aligning with environmental objectives it is of strategic importance to capture freight transportation characteristics more realistically. This paper characterizes freight transportation by using a complex network approach from multidimensional perspectives based on freight vehicle trips data. We first build two subnetworks from prefecture-level city-scale and county-level city-scale. Subsequently, network analysis indices based on complex network theory were applied to examine the topological structure and complexity of the freight transportation networks. Furthermore, the community detection method is introduced to reveal the networks’ clustering characteristics. The findings show that the prefecture-level city-scale network and the county-level city-scale network both have obvious small-world network characteristics, but the prefecture-level city-scale network has higher operating efficiency for goods movement. Additionally, the influence of the cross-border effect on the freight transportation network was verified. In terms of the community structure, the freight network shows distinct clustering features only at the county-level city-scale.

Improving the operational efficiency of transport is one of the main catalysts for raising the quality of life and socio-economic development. The prevailing global trends are aimed at establishing logistic chains from producers to consumers. The cross-border movement of world production within the framework of globalization, the deepening of integration processes between countries highlight the issues of developing a methodology for planning and evaluating international transport corridors from various points of view, and economic, technical, social, environmental and other aspects. The urgent issue is the harmonization of the technical and regulatory framework for the organization of «seamless» transportation, the synchronization of the technological cycles of various modes of transport, including operation of multimodal transport hubs. A large number of studies are dedicated to the modelling and control of traffic flows, new methods of forecasting the transport situation using the results of computer dynamic transport modelling, analysis of existing infrastructure resources and elimination of bottlenecks in the existing railway system (including through the expansion of the railway network and innovative methods of traffic control).Hence the achievement of target parameters of efficiency of production activity of all participants in railway transportations is possible through qualitative changes in the system of the organization of transportation process, the objective of the research was to study technological aspects of improvement of quality of functioning of the transport system in relation to activity of the Russian railways.The research applied methods of system analysis of scientific and technical data and technical and economic indicators of complex systems.The issues of implementation of end-to-end principles of transportation process management are considered, the concept of «technological polygon of transportation process management» is expanded. The analysis and grouping of methods for improving the efficiency of railway transport was carried out with regard to improving the operation quality indicators and refined model of rolling stock management, increasing the efficiency of the use of traction equipment, profiling of railway itineraries in respect of the preferred types of traffic, establishing sections well-provided for safe passage of freight trains and synchronized with the operation ranges of locomotives, organizing freightage in wagons withincreased axle load, removing barriers and restrictions in the power supply sector, etc.The transition to the «polygon» model of the organization of the technological process, the unification and optimization of the use of available resources, and, as a result, the reduction of risks of losses from transportation, service provision and unplanned use of resources are effective tools to improve the quality of rail operations.

The purpose of this paper is to review logistics concepts used in macro freight transportation modeling by various planning agencies at the national, state and city level. The chronological development of freight modeling endeavors are studied here and the logistics component incorporated in the modeling is identified. The key modeling tools are identified and analyzed to identify the efficacy of the model, ease of use, and data required to implement the model. The conclusion was that European freight models were more developed than North American freight models. The tools most widely used are the aggregate-disaggregate-aggregate model, input-output model, artificial neural network model, matrix estimation method and PCOD model. This paper will give transportation modelers a better idea of the freight modeling tools available.

Abstract According to the Urban Mobility National Policy (UMNP), Brazilian cities with more than 20,000 inhabitants are obligated to elaborate Urban Mobility Plans (UMPs). The literature shows a lack of national research on urban freight planning and a need for better understanding issues on cargo transportation for authorities, especially regarding decision-making on policies and on urban freight transportation planning. City Logistics solutions can be considered on UMPs to reduce the problematic urban freight transport. Therefore, a survey was applied to investigate the resources available within cities to draw UMPs, the solutions for cargo movement in Brazilian cities, and the perceptions of public managers about freight transportation. The results show that “restrictions” are the solutions most adopted by Brazilian authorities, including the representative sample for cities within the São Paulo State with more than 250,000 inhabitants. The conclusions point out that Brazilian cities are not prepared to develop an efficient urban freight plan, as public managers seem to be unconscious about urban logistics demands within their cities or have neglected aspects regarding urban freight within the UMNP.

Full textAbstract:
Well-being and economic growth are strictly correlated. Cities are the engines of an innovation-based economy where research and new ideas are the core input of production. Urbanisation is becoming synonymous of economic growth. People flock into cities, both in the developed and developing world, since here is where wealth is, where high quality services are available and life standards are comparatively higher with respect to other places. However, one has to acknowledge that growth also produces undesired negative effects. In fact, cities are net importers. They need to acquire consumption/intermediate goods, export production and get rid of waste. In other words, the existence of a city relies on a transportation system providing the necessary services for its functioning. The typical urban transportation system heavily depends on passenger and freight movements by road. While this dependency is, in some cases, less relevant for passenger transport, most of freight moved in, out, within and through a city relies on motorized road transportation. Trucks and vans are responsible for congestion, polluting emissions, accidents, noise, visual intrusion and stench. All these negative effects are concentrated where many citizens live and, consequently, produce relevant economic (e.g. time lost), environmental (e.g. air quality), and social (e.g. segregation) impacts. Cities to be attractive, sustainable and thriving need an efficient freight transportation system. Fast changing consumption patterns with the rise of e-commerce and home deliveries also point out to another dimension of cities: their need to adapt quickly to economic trends.
The papers in this special issue address, from alternative points of view and using different methodological approaches, some of the relevant and critical issues pertaining to land use planning and administration strategies in modern cities with respect to the urban freight sector.

Full textAbstract:
Food product transportation is one of the most problematic tasks considering the specific expectations in the context of the transport conditions. It seems to be a significant challenge for the freight carriers’ decision-makers. The proper organization and management of that process is the basis for the appropriate fulfilment of the needs of customers, related, among others, to the proper quality of delivered products (such as freshness, expiration date, etc.). The additional challenge in this context is the efficient delivery at the city area, taking into account typical city transportation problems, such as congestion, narrow ways, lack of the unloading areas, etc. The role of these tasks is analyzed in this paper, on the basis of the chosen parameters and technologies of the transportation process. The purpose of this paper is to study the rational freight fleet formation in the case of changing the parameters of material flow in time. It was found that with the other unchanged parameters of material flow, the change in ambient temperature affects the technological process of transportation, the type of vehicle for its movement and the structure of the vehicle fleet. Accordingly, the types of vehicles (tent or insulated) necessary for the movement of certain material flows, which require special conditions for their transportation, have been determined, in compliance with the temperature regime and periods of their use. The organization scenarios of the transport service of the studied distribution processes were proposed, taking into consideration the change in conditions for the transportation of material flow, purchase of insulated semitrailers or their rent. The proposed versions were calculated and evaluated under the given conditions, and based on the net present value, the best of the proposed options was found: the purchase of one insulated semi-trailer while hiring the remaining insufficient insulated vehicles.

Full textAbstract:
Purpose The purpose of this paper is to measure and map the potential transportation network impedance to last-mile delivery (LMD) using spatial measures representing attributes of road network and planning controls. Design/methodology/approach The transport network impedance is estimated as the potential hindrance to LMD as imposed by the characteristics of the built and regulatory environment. A matrix of key transport and planning measures are generated and overlaid in geographical information systems to compute and visualise the levels of transportation network impedance to LMD using a composite indexing method. Findings The mapped outputs reveal significant spatial variation in transportation network impedance to LMD across different part of the study area. Significant differences were detected along the road segments that connect key industrial hubs or activity centres especially along tram routes and freight corridors, connecting the Port of Melbourne and logistic hub with the airport and the Western Ring Road. Research limitations/implications The use of static measures of transport and urban planning restricts the robustness of the impedance index, which can be enhanced through better integration of dynamic and real-time movements of business-to-business LMD of goods. Spatial approach is valuable for broader urban planning at a metropolitan or council level; however, its use is somewhat limited in assisting the daily operational planning and logistics decision making in terms of dynamic routing and vehicle scheduling. Practical implications The built and regulatory environment contributes to the severity of LMD problem in urban areas. The use of land use controls as instruments to increase city compactness in strategic nodes/hubs is more likely to deter the movement of urban freight. The mapped outputs would help urban planners and logisticians in mitigating the potential delay in last-mile deliveries through devising localised strategies such as dedicated freight corridors or time-bound deliveries in congested areas of road network. Originality/value This is the first study that measured the potential transport network impedance to LMD and improved understanding of the complex interactions between urban planning measures and LMD. Micro-scale mapping of transportation network impedance at the street level adds an innovative urban planning dimension to research in the growing field of city logistics.

PurposeFreight network planning and the application of distribution innovations are popular fields of research on sustainable urban logistics. However, considerable research on freight network design lacks a comprehensive consideration of the application of distribution innovations. This observation implies that sustainable urban freight research appears highly fragmented in topics of network design and distribution innovations. From the perspective of long-term planning, this situation possibly serves as a barrier to further promotion of sustainability. The objective of this paper is to analyze existing research gaps of literature to further promote the sustainability of urban logistics systems from a future perspective.Design/methodology/approachThis paper employs a systematic literature review (SLR) method, which covers 164 papers and research works published in 2013–2018. The article corpus involved the innovative schemes of freight network design and the emerging delivery concepts in cities. Based on an analysis of articles' relevance, the most significant research contributions on both city logistics network design and exploitation of distribution innovations are detected.FindingsThis paper has found four research gaps in aspects of network design and distribution innovations. To respond to these gaps, we propose the research framework of sustainable and flexible future urban freight planning (SFFUFP) based on trends of city development, while discussing further research direction on urban freight planning.Originality/valueThe authors have found four research gaps in aspects of both urban freight network design and distribution innovations in which scholars could be encouraged to contribute. The research framework of SFFUFP can further promote sustainable urban logistics from a view of future management.

"Transport Service Provider Perception of Barriers and Urban Freight Policies in Brazil." Sustainability 11, no. 24 (December 4, 2019): 6890. http://dx.doi.org/10.3390/su11246890.
Full textAbstract:
The aim of this paper is to analyze the perceptions of the transport service providers on the barriers in urban freight transport and the restrictions imposed on freight vehicles, identifying which urban freight transport policies can improve this activity in Brazil. Principal component analysis allowed us to identify which are barriers in urban cargo transport and the restrictions imposed on freight vehicles. In addition, we evaluated freight policies that can improve the activity using probabilistic preference. We obtained the database from a web-based survey of transport service providers in Brazil. The results indicate that the urban freight vehicle restriction is related to congestion and availability of loading and unloading areas. The freight vehicle restriction is a result of the lack of information and data. The theft of cargo significantly impacts urban freight transport. Transport service provider company perceptions indicate an urban mobility plan as the most-required freight policy to improve freight mobility. To reduce the barriers to urban freight planning, an understanding of the problem involving the stakeholders is needed. To do so, the challenge is to change the culture in the transportation planning process by integrating various actors to create an urban logistics plan that generates opportunities for the city.

Introduction: In the 21st century, cities in developing countries have witnessed faster growth as compared with cities in developed countries. Countries like India, China and Brazil have one of the most densely populated cities in the world. The transport infrastructure in these cities struggles to deal with the increasing population and geographic sprawl. Though some efforts are made to improve the transportation systems in these cities, urban freight transport is largely overlooked as the focus remains on passenger transport. Methods: This study aims to assess the impacts of the city’s geographic sprawl on urban freight transport using the example of the textile industry in Surat, India. The sprawl of the city and its textile industry is measured based on historical maps, Google imagery, and establishment surveys. Changes in urban freight trip lengths are determined using the data of a commercial vehicle drivers’ survey. Results: In the last two decades, the city expanded geographically by almost three times. The relocation of textile manufacturing units led to a 40% increase in trip lengths and additional 56 tons of carbon dioxide generation per year. Due to the city sprawl, the overall efficiency of the urban freight transport system reduced. There is a need for a holistic planning approach towards urban freight movement and related urban infrastructure for sustainable freight flows. This can serve as a policy framework to decide on the location of a logistics hub or as guidelines to allocate manufacturing enterprises in the proximity of the urban area, thus enabling sustainable development of the city.

This paper assesses the effects on urban freight transportation of implementing Bus Rapid Transit (BRT) systems. BRT systems have been widely implemented in Latin American cities in recent decades, with positive results driven by their high capacity and relatively low cost. Implementing BRT strategic corridors has led to changes in land use, and has required some restrictions on other urban traffic, particularly freight. These restrictions have significantly affected the supply of goods to establishments along those corridors, restricting freight operations and urban freight traffic in general. This paper studies the overall effects of BRT system implementation on urban freight using Cali (Colombia) as a representative case study to understand the origin and size of these impacts. Six key criteria were analyzed to assess the impacts of implementing a BRT system: 1. Mobility patterns; 2. environmental impacts; 3. infrastructure; 4. land-use; 5. legislation; and 6. geographic distribution. Observations and semi-structured interviews were used to complement hard data. The results from Cali show that the areas surrounding BRT corridors generate more than 62% of urban freight traffic. This concentration of freight activity has exacerbated the negative effects of restrictions that have accompanied BRT implementation and altered freight mobility and land-use patterns, not only locally but within the city centre, as well as suburban areas. In summary, the results show that post implementation, a significant share of freight-related externalities were amplified and transferred from BRT corridors to other parts of the city and to inter-regional corridors as well.

This study is aimed at increasing the efficiency of multimodal freight transportations by forming a risks management system based on the identification of transport risk factors, methods of their measurement and management both at the projecting (planning) stage of the multimodal route and further on – in order to assess their possible impact on the efficiency of freight transportation in general. The authors examine the problematics of multimodal freight transportations organization in the context of transport risks management, which provides for the choice of such an option of management influences on elements of the transportation system (logistics centers, transport hubs, various types of transport, freight transport units, specific transport companies and their rolling stock, containers, etc.), in which freight delivery would be carried out in terms of the most efficient and qualitative indicators under the known initial conditions and existing restrictions. The article substantiates the proposals development in view of optimal relationships between elements of multimodal freight transportations on the basis of an efficient risks management system, which is a special type of management activity directed towards mitigating the influence of risk groups, determining the permissible (acceptable) level of risk based on methods that allow avoiding losses arising as result of a particular risk. A methodical approach to choosing the optimal multimodal transport-technological scheme is proposed, which allows considering subjective criteria (completeness of service, reliability, etc.) as decisive under the condition of relatively equal cost and time of alternative freight delivery options and in the context of permissible values of such objective criteria as storage conditions, high-speed mode of transportation in the territory of a particular country, region, city, axial load, climatic conditions, ecological restrictions, etc. At the scientific-methodological level, the stage of the decision-making process is generalized along with the separation of relevant goals in the context of managing transport risks in multimodal freight transportations, the observance of which will guarantee to ensure the acceptance by the operator of multimodal transportations of a rational and secure transport-technological scheme of freight delivery.

Full textAbstract:
Urban population increase results in more supply chain operations in these areas, which leads to increased energy consumption and environmental pollution. City logistics represents a strategy of efficient freight transportation and material handling to fulfill customer and business demands. Within the frame of this paper, the authors describe an optimization model of a multi-echelon collection and distribution system, focusing on downtown areas and energy efficiency, sustainability, and emission reduction. After a systematic literature review, this paper introduces a mathematical model of collection and distribution problems, including package delivery, municipal waste collection, home delivery services, and supply of supermarkets and offices. The object of the optimization model is twofold: firstly, to design the optimal structure of the multi-echelon collection and distribution system, including layout planning and the determination of required transportation resources, like e-cars, e-bikes, and the use of public transportation; and secondly, to optimize the operation strategy of the multi-echelon supply chain, including resource allocation and scheduling problems. Next, a heuristic approach is described, whose performance is validated with common benchmark functions, such as metaheuristic evaluation. The scenario analysis demonstrates the application of the described model and shows the optimal layout, resource allocation, and operation strategy focusing on energy efficiency.

Full textAbstract:
This study focuses on the route selection problem of multimodal transportation: When facing a shortage of containers, a transport plan must be designed for freight forwarders that realizes the optimal balance between transportation time and transportation cost. This problem is complicated by two important characteristics: (1) The use of containers is related to transport routes, and they interact with each other; and (2) Different types of containers should be used in different time ranges for different modes of transportation. To solve this problem, we establish a multi-objective optimization model for minimizing the total transportation time, transportation cost and container usage cost. To solve the multi-objective programming model, the normalized normal constraint method (NNCM) is used to obtain Pareto solutions. We conducted a case study considering the transportation of iron ore in Panzhihua City, Sichuan Province. The results demonstrate that using railway containers and railway transportation as much as possible in route selection can effectively solve the problem of container shortage and balance transportation time and transportation cost.

Today, one of the main challenges faced in urban logistics is the distribution of goods. In Brazil, mid to large cities have experienced consequences of unplanned urban sprawl and lack of adequate transportation infrastructure. The relationship between urban planning and transport stands out the attractiveness of some urban activities with direct impacts on the movement of people and goods and other component elements of urban space. The segment of bars and restaurants falls within this context, therefore is a vital activity responsible for significant percentage of jobs and revenue in a city. Altogether, foods & beverages commercial activities move daily large volumes of goods to meet the need of customers. This paper presents the results of a freight trip generation model developed for pubs and restaurants in Belo Horizonte (Brazil). Once performed the model determined the number of trips generated per day per establishment. In order to expand the discrete result to a continuous one, the results were geographically interpolated to a continuous surface and extrapolated within the city limits. The data for the freight trip generation model were obtained by survey. For this, we designed a structured questionnaire to obtain information about goods, frequency, operational time, place of performance of the loading/unloading of goods, establishment size and the number of employees. Besides these information, we investigated the acceptance of alternative practices in the delivery of goods, such as off-peak delivery. To accomplish the proposed models, we applied a simple linear regression, correlating the following variables: (i) Number of trips versus area of the establishment; (ii) Number of trips versus number of employees; (iii) Number of trips versus operation day of the establishment. With the results of the linear regression for travel generations, conducted the data interpolation based on the standard deviation of the results to define the sample classification bands. This interpolation method was chosen because it is one of the most suitable for analysis of spatially scattered points due to the straightforwardness of the model and because it does not consider extra noise such as slope and spatial constraints as barriers. In this method, interpolation is determined by the value assigned to each point (in this case the number of trips), wherein the closer the points the higher the correlation trend. Finally, the resulting trip generation surface was analysed together with other geographic data such as demographic data, road network density and socioeconomic data. Findings indicate the importance of a mathematic-geographic model for trip generation as a feasible approach for support transportation planning & operation for urban goods distribution. Critical information such as the high concentration of pubs and restaurants in the same region can reinforce the vocation of the city for trading. However, an elevated number of freight vehicles to meet a high and growing demand becomes a problem specially in areas where urban road network is not efficient (not properly designed and parking spaces not properly used). This study also highlights the need for an urban freight mobility plan and public policies, by offering sustainable alternatives for urban goods distribution, which improve the urban environment. By using geospatial analysis, the study delivered statistics data and maps to catch the attention of decision makers and transportation managers, therefore facilitate the discussion on transportation policies in the city of Belo Horizonte.

In general, the demand for delivery cannot be fulfilled efficiently due to the excessive traffic in dense urban areas. Therefore, many innovative concepts for intelligent transportation of freight have recently been developed. One of these concepts relies on drone-based parcel delivery using rooftops of city buildings. To apply drone logistics system in cities, the operation design should be adequately prepared. In this regard, a mixed integer programming model for drone operation planning and a heuristic based on block stacking are newly proposed to provide solutions. Additionally, numerical experiments with three different problem sizes are conducted to check the feasibility of the proposed model and to assess the performance of the proposed heuristic. The experimental results show that the proposed model seems to be viable and that the developed heuristic provides very good operation plans in terms of the optimality gap and the computation time.

Freight transport in urban areas entails benefits (i.e. free access to goods when needed), but also negative externalities (environmental, social and transportation impacts). In response to these problems, the concept of city logistics emerged, for the purpose of planning, organizing, coordinating and controlling physical and information flows in order to find a compromise between efficient freight distribution in urban areas and protection of the environment. A typical city logistics initiative is the Urban Freight Consolidation Centre (UFCC), the benefits of which are significant. Its financial issues though represent a huge problem for public administrations. However, a large customer network, comprising retailers participating in the initiative, could make the UFCC a self-financing scheme. The key to expanding the scheme is closely linked with marketing campaigns and customer care. Therefore, customer care analysis represents an important tool in developing UFCC schemes. In this paper, a new Customer Satisfaction Index (CSI) is proposed for evaluating UFCC service quality. The new index, named CSImod, is a modified version of the traditional CSI, but places greater emphasis on customer dissatisfaction, so as to analyse the most critical areas of the service with a view to improving them. The index has been tested using experimental data collected within the CIVITAS RENAISSANCE Project, in which the Bristol and Bath Freight Consolidation Centre (BBFCC) scheme was evaluated. The evaluation was done from a user perspective, i.e. the participating retailers. The CSImod places more importance on the most dissatisfied customers making it possible to understand why they are dissatisfied and with what. Thus, it is possible to intervene with the aim of improving those areas of the service that are perceived as the worst. In spite of the high level of satisfaction with the overall service provided by the BBFCC, thanks to the CSImod the analysis pointed out that some retailers are dissatisfied with the delivery time arrangements and also with deliveries that were getting wet, issues about which the BBFCC manager was totally unaware. The CSImod could be used by UFCC operators to extend the network of the retailers involved and could therefore provide an implicit solution for making the scheme self-financing.

The Shanghai government has outlined plans for the new vehicles used for the public transportation, rental, sanitation, postal, and intra-city freight to be completely powered by electricity by 2020. This paper analyzed the characteristics of vehicle emissions in Shanghai in the past five years. The potential reduction in road traffic related emissions due to the promotion and application of electric vehicle in Shanghai was evaluated. The potential reduction was quantified by vehicular emissions. The vehicular emissions inventories are calculated by the COPERT IV model under the different scenarios, of which the results indicate that promoting electric vehicles is the efficient measure to control all road traffic related emissions and improve urban air quality. The results also provided basis and support for making policies to promote and manage electric vehicles.

Purpose The transportation system in any city is complex and evolving, shaped by various driving forces and uncertainties in the social, economic, technological, political and environmental situations. Its development and demands upon it cannot be projected by simply extrapolating past and current trends. This paper aims to present a foresight study examining the future of urban mobility, focusing on the dense Asian city-state of Singapore. The objective is to develop scenarios for the future of urban mobility, to facilitate future policy implementation by highlighting long term challenges and opportunities for transportation planning in cities. Design/methodology/approach To create future scenarios, the authors first sought to identify key drivers of change through environmental scanning, expert interviews, focus group discussions and technology scanning. These drivers of change were subsequently used in a scenario planning workshop, organized to co-create alternative future visions for urban mobility 2040 with experts and local stakeholders. Findings Two scenarios emerged, called the Shared World and the Virtual World. For each scenario, the authors described the key features in terms of dominant transport modes for the movements of passengers and freight. Subsequently, the authors discussed possible implications of each scenario to the individual, society, industry and government. Originality/value As cities grow and develop, city and transport planners should not only address daily operational issues but also develop a well-informed, long-term understanding of the evolving mobility system to address challenges that lie beyond the five- or even ten-year horizon. By using scenario planning approach, the authors hope to prepare stakeholders for the uncertain futures that are continuously shaped by the decisions today.

Full textAbstract:
In recent years, the concept of a “Smart City” became central in the agenda of researchers, practitioners, and stakeholders. Although the application of information and communication technologies on city management has advanced exponentially, also other components would be needed for building a truly sustainable urban environment. Researchers from different domains debated the definition of a smart city and the conceptual variants. However, a broad view of the smart city field is still missing. This paper attempts to fill this gap by proposing a taxonomic classification of the most 105 outstanding smart city projects in Europe and North America. Collected data are then processed by statistical tools for clearly highlighting the success factors, trends and future paths in which all these projects are moving, along with different aspects (e.g., business model, purpose, industry). We then investigate the European and the North American Smart City concepts, illustrating the key role of mixed public and private partnerships in creating successful projects and the focus on the urban transportation, and freight and last-mile delivery in particular. Moreover, it emerges how the business modeling and the exploitation aspects have still low integration in the projects.

Full textAbstract:
Dynamic growth of automotive indicator and increasing level of freight being carried in the Polish cities are causing serious transport problems. Migration to the cities is a trend observed still in Poland that is expected to continue. Bottlenecks, delivery obstacles, congestion, traffic jams and air pollutions require prompt organizational and technological intervention. The article starts a discussion about the condition of the urban logistics in Poland, comparing various models from the local government authorities point of view and inhabitants. The author outlines the barriers and obstacles in the planning and implementing of the modern urban logistical solutions. The majority of municipal and local government authorities, despite the declared enthusiasm for the smart city concept, prefer traditional infrastructure investments, instead of joint and interdisciplinary planning of the combined organizational and technological solutions tailored to the needs of a specific city. There is an urgent need to introduce regulations limiting freight traffic in the Polish cities, road tolls depending on emissivity, payloads, parking infrastructure. There should be rules planned determining time windows in the urban transport, organizing in-city consolidation centers, etc. The paper includes recommendations for creating Urban Vehicle Access Regulation Schemes for the Polish cities. The article includes also the findings and recommendation for the Polish cities in the field of urban logistics. The author emphasizes, however, that there is still a lack of long-term investment plans in the field of logistics and freight transport in so-called smart cities. The paper demonstrates that the efficiency of the functioning of Po-land’s urban logistics network does not necessarily imply cost-intensive infrastructural development. The optimization of logistics activities should be brought about in urbanized areas primarily based on the organisational changes in the transportation system, customs, habits and behavioral patterns of its users as well as the altered functions of selected. Such an approach is the closest to the views expressed by the inhabitants; however, it all too often proves contradictory to the interests of the other stakeholders of the system. Any changes to the city’s transport layouts or systems, or mobility policies (as a broader concept), call for a broad public contribution when it comes to consulting projects and designing the improvements. Organisational and financial support is likewise indispensable, along with the development of an incentives system. The author also pointed out a need to monitor comprehensively the solutions in the field of urban logistics and urban freight transport of the Polish cities using socio-economic analysis tools. The selected methods of evaluating the urban logistics solutions, incl. comparative best practices analysis, have been discussed.

Full textAbstract:
In the era of public participation in government, public emotions and expectations are important considerations influencing urban construction, planning, and management. A desirable urban environment can make people feel at ease and comfortable and contribute to promoting positive public emotions. However, in the process of rapid urban development, the high-density and overloaded urban built environment has triggered people’s mental tension and anxiety and has contributed to negative emotions. Thus, this study aimed to explore the spatial distribution of public emotions and urban built environments in cities and to thoroughly investigate the correlation between urban built environments and public emotions. Considering the lack of dynamic elements analysis and emotions spatial analysis in previous studies, this study takes Wuhan City as an example, uses social media big data as the basis for text emotion analysis, introduces dynamic traffic elements, and establishes a multidimensional urban built environment measurement index system from five aspects: land use, spatial form, road and traffic, green space and open space, and daily life service facilities. Subsequently, the spatial distribution characteristics of public sentiment and urban built environment elements in Wuhan were analyzed. Finally, a geographically weighted regression method was used to analyze the degree of influence of different urban built environment elements on public emotions. The results showed that public emotions in Wuhan are not homogeneously distributed in terms of score and space and that there are significant differences. The urban built environment has a significant influence on public emotions. Higher land use mix, higher road network density, higher number of public transportation facilities, higher number of public open spaces, lower traffic congestion, and impact of freight transportation play important roles in promoting positive emotions. Therefore, in the process of urban construction, planners and decision makers should purposefully improve the quality of the built environment. Measures can include improving the mix of land functions, alleviating traffic congestion, avoiding the negative effects of freight traffic, rationally constructing green and open spaces, and improving various living facilities. This can help contribute toward improving urban functions and urban environments, and promote the construction of a people-oriented healthy city.

Full textAbstract:
Purpose The development of e-grocery allows people to purchase food online and benefit from home delivery service. Nevertheless, a high rate of failed deliveries due to the customer’s absence causes significant loss of logistics efficiency, especially for perishable food. The purpose of this paper is to propose an innovative approach to use customer-related data to optimize e-grocery home delivery. The approach estimates the absence probability of a customer by mining electricity consumption data, in order to improve the success rate of delivery and optimize transportation. Design/methodology/approach The methodological approach consists of two stages: a data mining stage that estimates absence probabilities, and an optimization stage to optimize transportation. Findings Computational experiments reveal that the proposed approach could reduce the total travel distance by 3-20 percent, and theoretically increase the success rate of first-round delivery approximately by18-26 percent. Research limitations/implications The proposed approach combines two attractive research streams on data mining and transportation planning to provide a solution for e-commerce logistics. Practical implications This study gives an insight to e-grocery retailers and carriers on how to use customer-related data to improve home delivery effectiveness and efficiency. Social implications The proposed approach can be used to reduce environmental footprint generated by freight distribution in a city, and to improve customers’ experience on online shopping. Originality/value Being an experimental study, this work demonstrates the effectiveness of data-driven innovative solutions to e-grocery home delivery problem. The paper also provides a methodological approach to this line of research.

Full textAbstract:
Widespread adoption of green vehicles in urban logistics may contribute to the alleviation of problems such as environmental pollution, global warming, and oil dependency. However, the current adoption of green vehicles in the last mile logistics is relatively low despite many actions taken by public authorities to overcome the negative externalities of distributing goods in cities. This paper presents a comprehensive literature review on studies investigating the adoption of green vehicles in urban freight transportation, paying specific attention to e-commerce. To shed light on the adoption of green vehicles in city logistics, the paper conducts a systematic review of the empirical literature on the topic. The 159 articles reviewed were classified into the following: (a) Optimization and scheduling (67 papers); (b) policy (55 papers); (c) sustainability (37 papers). Among the 159 articles, a further selection of 17 papers dealing with e-commerce, i.e., studies that highlight the most relevant aspects related to the integration of green vehicles in e-commerce urban logistics, was performed. Our findings indicate that green vehicles are competitive in urban deliveries characterized by frequent stop-and-go movements and low consolidation levels while incentives are still necessary for their adoption. The use of autonomous vehicles results the most promising and challenging solution for last-mile logistics.

Abstract A road, as the most important infrastructure on land transportation, plays a huge role on the movement of passengers and freight. According to its status, road is classified into national road, province road, city road, district road, and village road. The status of a road significantly affects the process of financing, planning, construction, and maintenance of that road. Therefore, a comprehensive study is needed before the status of a road is determined or changed. This paper discusses several aspects that are needed to be considered before the status of a road is determined or changed, with a case study of Gorontalo Outer Ring Road. These aspects are centre-of-activity hierarchy, road geometry, and the traffic volume. After all those aspects were discussed, the recommended status of Gorontalo Outer Ring Road is concluded. Keywords: rroad, land transportation, road status, centre-of-activity Abstrak Jalan sebagai prasarana utama transportasi darat memegang peranan penting terhadap pergerakan barang maupun pergerakan orang. Menurut statusnya, jalan dikelompokkan menjadi jalan nasional, jalan provinsi, jalan kota, jalan kabupaten, dan jalan desa. Penetapan status suatu jalan berdampak besar pada kegiatan pembiayaan, perencanaan, pembangunan, dan pemeliharaan jalan tersebut. Oleh karena itu, diperlukan kajian yang mendalam sebelum suatu jalan ditetapkan atau diubah statusnya. Pada studi ini dikaji aspek-aspek yang perlu diperhatikan ketika suatu ruas jalan akan ditetapkan atau diubah statusnya, dengan studi kasus Jalan Lingkar Luar Gorontalo. Aspek-aspek yang dibahas pada penelitian ini adalah aspek hierarki pusat kegiatan, aspek geometri jalan, dan aspek lalu lintas. Setelah semua aspek tersebut dibahas, dapat disimpulkan status jalan yang sesuai untuk Jalan Lingkar Luar Gorontalo. Kata-kata kunci: jalan, transportasi darat, status jalan, pusat kegiatan

Full textAbstract:
The attraction area division is the foundation of distribution and organization of freight flow among railway stations. The development of railway container terminal, large railway freight distribution center, is closely related to logistics planning and economy development of local city. In this study, we divide freight flow attraction area of inland railway container terminal by using gravity model, break-point model and weighted-Voronoi-diagram with SPSS and ArcGIS. And then under the target of minimal cost and time window limitations, we develop 0–1 integer programming model for freight flow organization optimization between inland terminal and its attraction area. Finally, this paper takes railway container terminal in Harbin as an example to test model feasibility under different speeds from different transportation modes. The results show that it is necessary to divide attraction area when choosing reasonable transportation mode from feeder nodes to railway container terminal. The improvement of feeder transportation speed is an effective method to improve freight volume, increase railway revenue and realize sustainable development of China Railway (CR) Express.

Full textAbstract:
Freight transportation can impact the effectiveness of smart city development if it is not well planned. Commodities with international flows such as soy can cause traffic in urban areas where ports are installed, negatively influencing economic (e.g. delays and fines), social (e.g. population quality of life) and environmental (e.g. intensification of pollutant and greenhouse gases emissions) dimensions. Thus, this paper aims to apply a location-allocation mathematical model to determine the ideal location of logistics integration centers - LICs dedicated to soybean transportation. We believe that, by properly locating structures that allow intermodality, the use of road transport would decrease by replacing it with intermodal alternatives with less environmental impact, reducing road congestion in urban centers under port influence. In addition, the total costs of the network would be optimized, promoting positive economic impacts on the soybean logistics chains. Therefore, eight scenarios were established varying the model's input parameters (such as investment and minimum volume of soybean moved through a LIC). The model was implemented in the Mosel language using the Xpress IVE solver version 1.24.24. The costs of each scenario were investigated, and the benefits related to the currently configuration (with no LIC) were pointed out. In the end, it was observed that the applied model might support government strategic planning (including, here, the design of smart cities).

Full textAbstract:
Freight distribution with electric vehicles (EVs) is a promising alternative to reduce the carbon footprint associated with city logistics. Algorithms for planning routes for EVs should take into account their relatively short driving range and the effects of traffic congestion on the battery consumption. This paper proposes new methodology and illustrates how it can be applied to solve an electric vehicle routing problem with stochastic and time-dependent travel times where battery recharging along routes is not allowed. First, a new method for generating network-consistent (correlated in time and space) and time-dependent speed scenarios is introduced. Second, a new technique for applying branch and price on instances defined on real street networks is developed. Computational experiments demonstrate the effectiveness of the approach for finding optimal or near-optimal solutions in instances with up to 133 customers and almost 1,500 road links. With a high probability, the routes in the obtained solutions can be performed by EVs without requiring intermediate recharging stops. An execution time control policy to further reduce the chances of stranded EVs is also presented. In addition, we measure the cost of independence, which is the impact on solution feasibility when travel times are assumed statistically independent. Last, we give directions on how to extend the proposed framework to handle recourse actions.
