Full textGrowing cities are increasing the demand for well functioning goods carrying traffic together with the other traffic. The number of zones for unloading goods in the centre of Linköping is small compared to the number of delivery addresses and the number of goods distributors. The attendant phenomena are congestion and costs of congestion. Therefore the local network for freight forwarders in Linköping has taken the initiative to the SAMLIC project. SAMLIC stands for Coordinated Retail Distribution in Linköping City. The aim of SAMLIC is to create an economically and logistically efficient system for goods distribution that is persistent and friendly to the environment. The participants in the project are the Swedish National Road and Transport Research Institute, the network for freight forwarders in Linköping city, the association for cooperation in the city of Linköping, the working team for inner-city transports, Swedish Biogas and Linköping University. The aim of this report is to elaborate a proposal to a functional system for coordinated retail distribution in the centre of Linköping both in the short- and long-term perspectives. Focus is put on analysis of efficiency and potential with coordinated distribution concerning terminal handling, vehicle utilisation and unloading at the consignees. A trial project with coordinated distribution called PILOT has been carried out during the spring of 2004. The aim of the trial project was to give good quantitative information of possible benefits with coordinated distribution that can be used for further estimations of the potential of a larger system. From the gathered information analyses will be done to see if the vehicle load factor has increased and if the vehicle movements have decreased. The PILOT that was carried out included only general cargo and three freight forwarders. A summation of the amount of goods during the trial project does not give a complete image of the total amount of goods that is delivered to the centre of Linköping. Therefore a complementary investigation has been carried out with the main purpose to estimate the magnitude of the total volume of goods. The report also discusses methods for calculation of the number of vehicle movements in coordinated and ordinary distribution respectively and methods for calculation of vehicle load factor. The calculations show that the total time for deliveries with coordinated distribution is reduced with 14 % compared to if the same amount of goods would be distributed the conventional way. As a result of coordinated distribution, every fourth vehicle involved in the deliveries can be excluded from city traffic and used for other assignments, due to the fact that the load factor expressed as the number of kilograms per pallet space has increased with approximately 50 %. A reduced number of vehicle movements have the effect of decreasing pollution, disturbing noise, less accidents and less congestion. Economic profitability is important to accomplish for a successful system with a joint venture in coordinated distribution. No matter which form the coordinated distribution takes, the savings for the freight forwarders must be of such a dimension that they find it profitable to join instead of delivering the goods by themselves.

Full textAlong with the growth of cities and towns around the world, our focus on enviromental problems increases, and so do the demands on a functional distribution system for all kinds of goods. One way of meeting these demands is to coordinate the distribution of goods, a method that has been tested and evaluated in different national as well as international projects. In the national project SAMLIC (coordinated distribution of goods in Linköping City), similar aspects have been discussed, but with the focus being on creating an economically and logistically efficient distribution system for all parts involved. The effects of such a focus are particulary positive since improved enviroment as well as improved service are acheived. One important aspect of the SAMLIC-project, is that the initative was taken by the industry in the year 2000. It was motivated by the realization that the great amount of transport in and out of the centre of Linköping resulted in crowding, which proved very costly. The reason for crowding was that the numbers of loading zones were too few in relation to the number of distributors and companies in the City. These problems increased as the City expanded and it was inevitable that something had to be done in order to improve the situation. Participants of the SAMLIC-project are the network for conveyors within Linköping City, “Svensk Biogas”, the working-team Inner City Transports, The Group for City-Cooperation, the University of Linköping and the Swedish National Road and Transport Research Institute (VTI), which since spring 2003 is pursuing the project. A PILOT-project was undertaken during spring 2004 within the framework of the SAMLIC-project. The purpose of the PILOTproject was to gather data forming a foundation for the design of an economically and logistically efficent system of distribution. The purpose of the present study was to establish what effects different changes of the present distribution system would give rise to on transport and traffic. Thus, the effects of codistribution on transport were studied by means of statistical modelling, while the traffic simulation program CONTRAM was used to investigate the effects of codistribution on traffic, a program not yet used in this context, to our knowledge. The results of the statistical modelling showed that codistribution may reduce the total driving-time by 14 % in average. The statistics also indicated that the average weekly time reduction may be approximately 26 %. The results further reveal that codistribution would reduce the number of stops, which would result in an increased number of custumors per stop. The average reduction of the number of stops per week was estimated to approximatly 30 %. The results of the traffic simulations were analyzed by comparing ordinary distribution procedures with distribution according to PILOT- or SAMLIC- distribution and revealed that codistribution as compared to ordinary distribution resulted in positive as well as negative changes of traffic flow. In some parts of the road the flow increased while in other places it decreased. The important point, however, is that the reduction of truck-flow occurred primarily in the most central parts of the City, whichled to a reduction of exhaustemissions. This study suggests that different effects on traffic may be induced by codistribution and reveals in which areas these effects would be likely to occur. In terms of the effect of codistribution on queueing, speed differences and time consumption, this study failed to establish any difference between the two distribution procedures compared. This may be due to a lack of a sufficiently sofisticated analyzing technique. It may, however, be possible to produce a more detailed analysis of possible differences between the distribution procedures by using a micro-simulaion tool. Still, the results of the present study suggest that codistribution would improve the present transport situation in several ways. The SAMLIC-project is an ongoing project which at present is at a stage when decisions are to be made about matters such as responsibility assignment, criteria of specification, insurance matters and the allocation of different benefits. Not until these and similar further problems are solved will it be possible to initiate a long term system of codistribution.

Full textIn Sweden, one third of the carbon dioxide emissions are generated by the transport sector. The biggest contributor of emission in this sector is road traffic. In addition to emissions of greenhouse gases, trucks contribute to particle emissions and noise in urban areas. The purpose of this thesis is to provide a status report of Halmstad's urban truck transports by means of a traffic survey, a questionnaire and a literature study, thus presenting measures to reduce the environmental impacts of trucks. The result found in the survey is that the majority of the Swedish-registered trucks have diesel engines and the majority were Euro 5. Approximately 75 percent of the vehicles were heavy trucks. The questionnaire showed that accessibility in Halmstad needs to be improved and less than half of the companies coordinate their transportation. The conclusion is that there are several opportunities to reduce the environmental impact of trucks in the urban area in Halmstad. For example, the possibilities for coordinating transports in Halmstad's urban area needs to be improved. A transshipment terminal in Halland can reduce road traffic and increase railway transports. An environmental zone would demand that the trucks should contribute to less emissions and better air.

Full textUrbanization and city expansion result in an increasing need of transportation of goods, and in order to maintain efficiency, measures are needed. The aim of city logistics is to minimize negative impacts associated with city center goods distribution, such as traffic congestion and negative impacts on the living environment. Several city logistic measures have previously been suggested, such as freight consolidation, governance and advanced IT systems. Within the SAMLIC project started in 2004, a demonstration project known as PILOT was carried out in central Linköping, wherein the concept of freight consolidation was applied in reality. The objective was to evaluate the economic potential of freight consolidation. The aim of this thesis was to formulate mathematical models of the distribution of goods in a medium sized Swedish city. The models are to be used in the evaluation of city logistic measures, focusing on freight consolidation. The distribution problem is modelled as a vehicle routing problem, and methods for solving the resulting optimization problems have been implemented. Using data from PILOT, the models have been applied on Linköping with the purpose of evaluating the methods, as well as investigating the potential of using models for planning the distribution of goods. Conclusions involve that analyses of, and comparisons between, city lo-gistic measures can be efficiently made using mathematical models. The case study also indicates that goods distribution can be improved through the use of optimization methods, which further motivates mathematical modelling.

Full textI och med att städerna blir allt mer befolkade har stadsdistributionen blivit en stor logistisk utmaning. Några vanliga problem i innerstäderna är begränsad framkomlighet och tomgångskörning. Många av Sveriges kommuner ligger överde gränsvärden för PM10som bestämts av EU. Sundsvall är en av dessa kommuner och har som vision att skapa en hållbar stad och region. Sundsvall Logiskpark AB ingår i ett EU-projekt, SMARTSET, som är ett samarbete mellan flera städer i Europa. SMARTSET Sundsvall handlar om att fram en marknadsmässigt hållbar modell för citylogistik. Undersökningens syfte äratt jämförasamt bedöma potentialen hostvå logistikmodellerför samordnad varudistribution,med en mikroterminal,in till Sundsvalls Stenstadmed nuläget.För att uppnå undersökningens syfte har kartläggning av nuläget gjorts med hjälp av interjuver med speditörer samt identifiering av kriterier för en multikriterieanalys. I resultatet har intervjuerna sammanställts och legat till grund för dedata som har använts i multikriterieanalysen. För att få värden på de olika kriterierna har beräkningar gjorts och sedan har beroendet mellan de olika kriterierna illustrerats i scatter plots. Det har visat sig att logistikmodell1 och 2 är bättre än nuläget på majoriteten av kriterierna.Undersökningens huvudsakliga syfte har uppfyllts då multikriterieanalysen harvisat att båda logistikmodellernaär lönsam för speditörerna samt minskar utsläppen i Sundsvall. Undersökningen har också visat att det är fler faktorer än bara lönsamhet och miljöpåverkan som påverkar en implementation av någon av dessa logistikmodeller.För att vidareutveckla denna undersökning krävs det att fler speditörer intervjuas samt att butikernas kravspecifikation sammanställs. För att få ett projekt med längre livslängd än bidragsperioden behövs finansieringssätt identifieras.
