Experiments with Common Voles (Microtus arvalis) Using Different Corridor Widths." Animals 9, no. 6 (May 29, 2019): 291. http://dx.doi.org/10.3390/ani9060291.
Full textAbstract:
Animal personality may affect an animal’s mobility in a given landscape, influencing its propensity to take risks in an unknown environment. We investigated the mobility of translocated common voles in two corridor systems 60 m in length and differing in width (1 m and 3 m). Voles were behaviorally phenotyped in repeated open field and barrier tests. Observed behavioral traits were highly repeatable and described by a continuous personality score. Subsequently, animals were tracked via an automated very high frequency (VHF) telemetry radio tracking system to monitor their movement patterns in the corridor system. Although personality did not explain movement patterns, corridor width determined the amount of time spent in the habitat corridor. Voles in the narrow corridor system entered the corridor faster and spent less time in the corridor than animals in the wide corridor. Thus, landscape features seem to affect movement patterns more strongly than personality. Meanwhile, site characteristics, such as corridor width, could prove to be highly important when designing corridors for conservation, with narrow corridors facilitating faster movement through landscapes than wider corridors.

AbstractThe fragmentation of jaguarPanthera oncapopulations as a result of habitat loss is considered to be one of the main challenges for the conservation of the species. Corridors have been proposed as a means of maintaining connectivity and the long-term viability of jaguar populations. The corridor that connects the jaguar conservation units of Calakmul and Laguna de Terminos in Mexico has been considered to be a link for the movement of individuals between these units but its functionality had yet to be verified. During 2012–2014 we divided the corridor into four sections, where we used camera traps to verify the corridor's functionality. We obtained 106 photographs of jaguars, proving the presence of jaguars (including resident jaguars and females) in three of the corridor sections. We did not record any individuals in more than one section of the corridor. The presence of several resident jaguars and females throughout the corridor suggests that portions of the corridor should be incorporated into the Calakmul and Laguna de Terminos jaguar conservation units. Nevertheless, to confirm that the corridor is fully functional it is necessary to obtain evidence of movement of jaguars among the various sections of the corridor. Our results suggest that the area should be included in regional conservation strategies.

AbstractCorridors are expected to increase species dispersal in fragmented habitats. However, it remains unclear how the quality of corridors influences the dispersal process, and how it interacts with corridor length and width. Here we investigate these factors using a small-scale laboratory system where we track the dispersal of the model organism Collembola Folsomia candida. Using this system, we study the effects of corridor length, width, and quality on the probability of dispersal, net movement, body size of dispersers, and the rate of change in population size after colonization. We show that corridor quality positively affected dispersal probability, net movement, and the rate of change in population size in colonised patches. Moreover, corridor quality significantly affected the size of dispersers, with only larger individuals dispersing through poor quality corridors. The length and width of corridors affected both the rate at which populations increased in colonised patches and the net number of individuals which dispersed, suggesting that these physical properties may be important in maintaining the flow of individuals in space. Our results thus suggest that corridor quality can have an important role in determining not only the probability of dispersal occurs but also the phenotypes of the individuals which disperse, with concomitant effects on the net movement of individuals and the rate of change in population size in the colonised patches.

Full textAbstract:
Ecological and anthropogenic corridors are becoming more common worldwide, but little is known about how corridor size (width) affects species' movements, and thus their effects. Here we investigated whether 4- and 8-m wide anthropogenic corridors (seismic lines) cleared for petroleum (oil sands) exploration in boreal forests in Alberta, Canada, act on altering the behaviour of a habitat generalist butterfly, the Arctic fritillary ( Boloria chariclea ). Specifically, we captured 539 Arctic fritillaries and released them in seismic line corridor or control sites with no structural directionality (i.e. forests and clearings), and recorded both their initial direction (along the seismic line or not) and persistence in directional movements. Arctic fritillaries moved inside these lines twice as often as they left them, and maintained their initial direction more often, regardless of line size and independently of forest structure or sex of individuals. Thus, anthropogenic corridors as narrow as 4 m can affect insect movements. Given the vast area of boreal forests disturbed from seismic assessments, investigating if the effects of these dense, localized lines affect population dynamics and species interactions would provide important insights to managing this ecosystem and identifying restoration actions.

Full textAbstract:
Abstract Investigating landscape-level movement patterns of migratory animals can be challenging, but this is a major component of some animal’s life history and behavior. In particular, bat migration has been difficult to characterize, yet recent research on bat migratory ecology has made major advances. It has been largely accepted that rivers and other linear landscape features may be important migratory corridors for bats during both long- and short-distance migrations. We assessed the migratory behavior of multiple temperate bat species along the Missouri River, a major river corridor in North Dakota, during March through October of 2016–2017. Bat detectors with paired microphones were deployed and oriented parallel to the riverbank. This configuration permitted detection of directional passes of bats, approximately 10–20 m above the microphones and 40 m into the river, which were used as an estimate of migratory behavior. We found the effects of season and species explained less than 2% of the variation of directional passes, indicating an absence of season-specific movement patterns along the studied river corridor. Although our study only assessed a portion of a major river corridor, the results suggest that migratory movements of bats along rivers may not be as straightforward as once thought, highlighting the need for future studies investigating the fine-scaled movement patterns of bats during migration.

Full textAbstract:
Roads are the link between geographic space and human socio-economic activities, promoting local economic development, and simultaneously causing various negative effects, such as segmentation, interference, destruction, degradation, and pollution. In China, the construction of roads is rapid, which might affect wildlife movement, landscape pattern, and land use change, thereby, affecting the conservation of heritage sites. In the present study, the minimum cumulative resistance model, along with geographic information system technology, was adopted to compute the ecological corridor for wildlife movement between the source patches and to analyze ecological corridor changes under two conditions (road presence/absence) at two time points in Kanas, nominated as a World Natural Heritage site. The relationships between the ecological corridor changes and various factors, including the cutting index of the ‘road-effect zones’, terrain, and road geometric characteristics, were examined using the geographical detector model to identify the influencing factors and mechanisms of the corridor changes, in order to rationally simulate the potential ecological corridors. In addition, the detached and fragmented ecological patches can be connected to effectively protect the biodiversity, biological habitats, and species, which are important means to achieve regional sustainable development and ecological construction.

Full textAbstract:
Despite the general lack of theoretical or empirical support, biological corridors are assumed to mitigate the detrimental effects of habitat fragmentation by increasing landscape connectivity. To test the hypothesis that mechanisms which affect immigration rates from a source to a target patch are affected by the presence of a corridor in an otherwise unsuitable matrix, we created two strongly contrasting pathways in replicated field experiments. One pathway type included only bare mineral soil, the other included a potential corridor. We conducted these experiments with Ensatina eschscholtzii, a salamander in the family Plethodontidae. Pathways with surface organic material removed provided a harsh environment for E. eschscholtzii, which was reflected by lower selection, shorter residency time, and higher movement rates than on pathways that contained vegetation (corridor pathways). However, the numbers of E. eschscholtzii reaching target patches connected by corridor pathways were greater than those reaching target patches connected by bare pathways only in plots in which the matrix environment seemed most severe. Our results suggest that identifying candidate corridor areas on conservation maps might be difficult because animals may show compensatory behavioral responses to different types of habitat separating source and target patches. We argue that knowledge of a species' habitat-specific dispersal behaviors is critical to reliably designating corridors as functional components of reserve design.

Full textAbstract:
The planning of New South Wales (NSW) and other Australian health facilities is guided by the Australasian Health Facility Guidelines (AHFG), which prescribe allowances for circulation (corridors and similar areas for movement between spaces) of between 10% and 40% of functional floor areas. A further allowance of up to 28% for Travel and Engineering is then assumed (University of NSW & Health Capital Asset Managers' Consortium, 2005). Therefore the “circulation” and “travel” space manifested as the corridors and similar movement spaces within health facilities is both extensive and expensive. Consequently, such space often becomes regarded as a necessary evil and, in the name of efficiency, is often minimized wherever possible. This paper revisits the view that corridor space allocations (circulation) must always be minimized to achieve design or functional efficiencies. Minimizing circulation or travel inevitably assumes that the realized space savings will then be reallocated to “more important” areas of the facility. Yet the corridors and other movement spaces also are very important to the functioning of multidisciplinary clinical teams and the quality of care delivery. Ultimately, inflexibly reducing the space allocated to such spaces may be regarded as a false economy.

Full textAbstract:
A comprehensive goods movement study of the California Interstate 40 corridor (from Barstow to Needles) has recently been completed. This study attempted to characterize goods movement in the region, perform a corridor emissions analysis, and make recommendations in terms of capacity and improvements, as well as economic feasibility of using rail in conjunction with trucks for goods movement. The emissions analysis of goods movement along the I-40 corridor is examined, specifically emissions of carbon monoxide, hydrocarbons, nitrogen oxides (NOx), and particulate matter associated with both truck and rail traffic. Heavy-duty diesel truck emissions are estimated using truck activity data recorded along the corridor. A unique methodology is used to calculate these truck emissions, incorporating road grade factors and determining engine load on a link-by-link basis. These emissions are then compared with the emissions associated with freight trains that travel along this I-40 corridor. On the basis of current (1994) truck and rail volumes, it was found that goods moved by rail produces lower emissions, except for NOx, which is slightly higher for rail. The factor decrease of other pollutants ranges from 2.49 to 8.50, which is consistent with other recent studies. Given the amount of pollutants produced by trucks, shifting some of the freight from trucks to rail with a greater emphasis on intermodal business should reduce the total freight emissions along the I-40 corridor.

Full textAbstract:
"A series of full-scale fire tests were performed, using a fire compartment and an adjoining long (30+ m) corridor, as part of an effort to quantify the dynamics associated with smoke transport within a corridor. The tests were performed at the U.S. Coast Guard Research and Development Center’s Fire and Safety Test Detachment in Mobile, Alabama on board the Test Vessel Mayo Lykes. The resulting empirical data was analyzed in an effort to develop a method that could be used to estimate the movement of smoke within a corridor. The objective is to potentially incorporate this method into a smoke movement analysis “tool†that could, in turn, be used in conjunction with a fire safety analysis methodology previously developed by the U.S. Coast Guard; the Ship fire Safety Engineering Methodology (SFSEM). The goal is to develop a smoke movement analysis “module†that can be utilized in conjunction with the SFSEM when conducting an overall fire safety analysis of a ship. Of particular interest is the speed at which the smoke propagates along the length of the corridor. The focus of a smoke movement module would be life safety. A conservative assumption is made that if smoke is present in sufficient quantities to fill a corridor, then the corridor is to be considered untenable and not available as a means of egress. No attempt is made to address toxicity or density issues associated with smoke. This analysis developed correlations for the corridor smoke velocity, both as a function of the heat release rate of the associated fire and the upper layer temperatures within the fire compartment. Problems associated with the data collection and the narrow range of fire sizes used had a detrimental impact on the confidence level in the correlation based on heat release rate. The data do appear to confirm the results of previous efforts that indicated a weak relationship between the heat release rate and smoke velocity, on the order of the one-third to one-fourth power. The temperature data tended to be less problematic. This correlation shows promise for potential use with both the SFSEM and other existing computer models/routines. However, unlike previous studies of this relationship, the results of these data suggest that the velocity-temperature relationship is linear and not a square-root function. The test data were compared to predictive results using the CORRIDOR routine within FPETOOL. In general, the CORRIDOR results provided a reasonable good correlation to the tests data. Both the wave depth and temperature loss within the wave, as a function of distance, were consistently over-predicted. The velocity results were mixed, but were generally within 20 percent of the test data. The results of this study show promise, with respect to developing a correlation that can be used a method for predicting smoke movement in a corridor. However, due to the questionable nature of some of the data estimates, coupled with both a lack of sufficient number of tests and a limited range of fire sizes used, additional test data will be required to further validate the accuracy and refine the correlation(s) suggested by this work."

Full textAbstract:
This thesis considers numerical, physical and theoretical modelling approaches to investigate the influence of a person's wake on the dispersion of an airborne pathogen in a hospital corridor and the implications this has in terms of infection risk. The various physical and computational modelling approaches were conducted using geometries corresponding to a 1:15 reduction in length-scale, when compared to the full-scale, and then interpreted in the context of a full-scale scenario in a hospital corridor. The movement of people in a corridor was approximated using a translating circular cylinder. A physical water-bath model was used to investigate contaminant transport using food-dye in a channel with different sized cylinders and translation frequencies. Dye concentrations were quantified through a calibration method dependent upon changes in light-intensity, leading to accurate tracking of the dye and allowing the amount of dye in different regions of the water-bath to be calculated over time. The centre of mass of the dye cloud was found to be dependent upon the square root of the translation frequency, amplitude, cylinder diameter and elapsed time. Based on the hypothesis that the dispersal of the dye could be described by a turbulent diffusion process, a theoretical model was constructed to predict the evolution of the dye concentration using a Gaussian function, which agrees well with experimental data for a broad range of cylinder diameters and translation properties. Two and three-dimensional computational fluid dynamics (CFD) models were developed to investigate the transport of a passive scalar due to a translating cylinder in a channel, their geometries and boundary conditions bearing close resemblance to the water-bath. Seven turbulence models were tested to determine the most suitable, using the water-bath data for validation. The shear-stress transport (SST) model was found to offer solutions in closest agreement with experimental results and theoretical predictions, as well as offering up to a 70% reduction in computation time compared to SAS, DES and LES turbulence models. The commonly used k-epsilon model was found to be inappropriate for modelling the flows encountered here. The numerical and theoretical models were used to investigate a number of scenarios in a corridor at the full-scale where an infectious contaminant is released. This includes a unidirectional flow applied along the corridor, where it was shown that the wake of the cylinder was still able to transport contaminant `upstream' against the direction of the flow. This implies that a walking person may be able to transport an airborne contaminant in their wake even in the presence of ventilation. Infection risks were calculated for a person making a single pass and multiple passes of the corridor based on the amount of contaminant inhaled and published data on the infectiousness of different pathogens. Results showed that the theoretical model developed here led to each individual breath having its own infection risk based on temporal and spatial differences, whereas a model assuming a well-mixed contaminant distribution did not. Results demonstrate that a person's wake is likely to influence the spread of an airborne contaminant in a hospital corridor, even if ventilated within current recommended guidelines. This highlights that a person's risk of infection, in the presence of airborne pathogens, is partly determined by any human traffic passing through the space before them and not solely on any ventilation within the space, as is often assumed in airborne infection models. Furthermore, the experimental work has provided strong validation data for the CFD models and allowed for the construction of uncomplicated yet powerful theoretical models. It has been shown that, when appropriate modelling assumptions are taken, confidence can be had in CFD predictions of contaminant transport involving complex flow behaviour, such as eddy shedding, within a built environment. The study also confirms that poor selection of `default' modelling assumptions, for example use of the k-epsilon turbulence model, will provide very poor predictions, highlighting need for careful selection of each aspect of a model.

Ibarra-Macias, Ana C. "Effects of Habitat Fragmentation on the Distribution and Movement of Tropical Forest Birds." Scholarly Repository, 2009. http://scholarlyrepository.miami.edu/oa_dissertations/481.
Full textAbstract:
Habitat loss and fragmentation occur at unprecedented rates, especially in tropical countries where human activities have deforested or degraded around 80% of tropical rainforests. Tropical forest fragmentation is considered the main cause of extinction of tropical forest avifauna, yet the mechanisms by which fragmentation affects bird populations are poorly understood. The present study investigates the pattern of bird species distribution in a fragmented landscape in tropical southeastern Mexico and the relation of bird community and species distribution patterns to landscape and fragment characteristics. Area and isolation of forest fragments were the main determinant of species richness and abundance in fragments, especially for forest-dependent species. The significant effect of isolation on species persistence in forest fragments suggests that limitation of dispersal is one potential mechanism by which fragmentation affects species distribution in the landscape. To understand how fragmentation can affect bird dispersal in a fragmented landscape, the effect of open areas and corridors on movement patterns of forest birds was investigated. The evidence presented in this study supports the idea that bird movement is restricted by open areas, especially for forest-restricted birds. Forested corridors had a positive effect on movement rates of forest birds, potentially acting to preserve movement and dispersal processes, and ultimately species persistence, in heavily fragmented landscapes.

A análise da morfologia é uma importante ferramenta para avaliação das características internas do sistema bacia hidrográfica. Os atributos morfológicos podem demonstrar um padrão de comportamento dos processos ocorridos em seu interior, sobretudo os processos hidrogeomorfológicos, como enxurradas e corridas de detritos. As corridas de detritos possuem características específicas, em sua maioria relacionadas aos canais de drenagem, portanto, sua análise morfológica é fundamental para o entendimento do processo. São importantes os estudos que visam compreender de forma mais aprofundada os condicionantes relacionados à ocorrência de corridas de detritos, devido tanto à magnitude quanto e, principalmente, ao seu poder destrutivo, e, sobretudo, devido a recorrência do processo. Conforme o exposto, esta pesquisa teve como objetivo central avaliar a suscetibilidade de bacias hidrográficas a partir da análise de parâmetros morfológicos e sua relação com a magnitude das corridas de detritos ocorridas em 1967 no município de Caraguatatuba/SP, visando a elaboração de um índice de potencial de magnitude e suscetibilidade com base nos resultados. Para alcançar tal objetivo, as seguintes etapas metodológicas foram definidas: i) seleção de bacias hidrográficas com evidência de ocorrência de corridas de detritos; ii) mapeamento dos parâmetros morfológicos; iii) caracterização morfológica dos depósitos e definição da magnitude das corridas de detritos de 1967; e iv) elaboração de índice de potencial de magnitude e suscetibilidade à ocorrência de corridas de detritos. Os resultados mostraram a influência dos parâmetros morfológicos na magnitude das corridas de detritos, com destaque para perfil longitudinal, hierarquia de drenagem e área da bacia acima de 25°. As bacias classificadas com nível de magnitude maior obtiveram os valores mais críticos com relação a estes parâmetros. A metodologia utilizada para determinação da magnitude se mostrou eficiente, ficando as consequências potenciais condizentes com a realidade. Com o estabelecimento da relação entre os valores críticos dos parâmetros e a maior magnitude, foi possível a elaboração de um índice de potencial de magnitude e suscetibilidade com base nos parâmetros morfológicos. Esta pesquisa contribui para os estudos referentes às corridas de detritos, sob uma perspectiva geomorfológica, agregando mais informações a respeito do processo e colaborando para o melhor entendimento de sua dinâmica na Serra do Mar.The morphological analysis is an important tool in the evaluation of the inner characteristics of the hydrographic basin system. Its attributes demonstrate a pattern of behave of the processes occurred in the basin, especially hydrogeomorphic processes, such as flood and debris flow. Debris flow have specific characteristics, mostly related to the drainage channels, being primordial the study of the characteristics of the hydrographic basin. Studies which aim to better understand the conditioning factors related to the occurrence of debris flow are important due to the magnitude but also the recorrence of the process. As explained before, the main goal of this research was to evaluate susceptibility of hydrographic basins through morphological parameters and its relation with the magnitude of the debris flows occurred in Caraguatatuba, 1967, aiming to elaborate an index of potential of magnitude and susceptibility based in the results. To achieve this goal, the following methodological steps were defined: (i) selection of hydrographic basins with evidence of occurrence of debris flow; (ii) morphological parameters mapping; (iii) morphological characterization of the deposits and definition of the magnitude of debris flow; and (iv) elaboration of an index of potential of magnitude and susceptibility to de occurrence of debris flow. The results showed the influence of the morphological parameters in the magnitude of debris flows, highlighting the parameters longitudinal profile, drainage hierarchy and area above 25°. The basins classified with higher magnitude obtained the most critical values relation to those parameters. The methodology used to determine the magnitude proved to be efficient, with the potential consequences consistent with the reality. With the establishment of the relation between the critical values of the morphological parameters and the basins with higher magnitude, it was possible to elaborate an index of potential of magnitude and susceptibility. This research contributes to the studies related to debris flow from a geomorphological approach, adding more informations about the process and collaborating to better understand the debris flow dynamics in the Serra do Mar.

En ny skola för årskurs 4-9 planeras i Kungsör. Den gamla skolan är delvis riven på grund av de fukt- och mögelskador som upptäckts. Mitt projekt är en tillbyggnad till den del av den gamla skolan som inte skadats. Den nya skolan ska rymma både mellan- och högstadie med 525 barn och ungdomar, samt 45 lärare och övrig personal. Det är en stor arbetsplats i en liten kommun. Sedan tidigt i projektet har essän 'Att kasta tjejkast' av Iris Marion Young påverkat grundidén bakom utformningen av den nya skolan. Denna text, i kombination med ett kritiskt förhållningssätt till den idag rivna skolans planutformning med många korridorer, ledde tillundersökningar om rörelsemönster och möjligheten att påverka sina rörelsemönster, i mitt fall för elever i en skola. Jag har jobbat emot korridorer som enda kommunikationselement och för ett alternativt rörelsemönster som istället låter människan själv att bestämma sina rörelsemönster i byggnaden.A new school for years 4-9 is planned to be built in Kungsör, Västmanland. The old school, at the same site, is partially demolished because of damp damages. My project is an extension to the part of the old school that is not damaged and still exists. The new school will accommodate both elementary and secondary school with 525 children, 45 teachers and other staff. It's a big work place in a small community. Since early in the project, the essay 'Throwing like a girl' by Iris Marion Young affected the basic idea of the design of the new school. This text, combined with a critical approach to the floor plan of the now demolished school with many corridors, led to studies of movement patterns and the ability to influence your movement pattern. I have tried to eliminate corridors and instead creating a large room where the alternative movements is taking place. Here the people, instead of corridors, decide where to go and how to move.

King's passing in many ways captured the transition to a youth movement through which one could actually make tangible political claims beyond the meaning of civil rights.

Full textAbstract:
Few traveling between Santa Fe, New Mexico, and the Rio Grande valley realize that they are traversing one of the most significant American Indian migration and settlement corridors in the Southwest, a well-watered and fertile floodplain that served to link peoples of the southern Rocky Mountains and the San Juan River to those of the Jemez range and Sangre de Cristo Mountains, and the Rio Grande, across some 300 miles. This chapter gives an overview of Pueblo (Tiwa, Tewa, Towa, Keres, Hopi, and Zuni), Apache, Navajo, and O’odham histories, and reveals a dual process of migration and place making across a millennium. The Southwest has a high variability in seasonal precipitation, and its peoples have demonstrated creative and adaptable cultures that allowed for movement to new locations and the creation of new homelands as a crucial aspect of their survival.

Full textAbstract:
Using industry publications and American archival documents from the Allied occupation period, chapter 5 focuses mainly on railway accident prevention measures to illustrate that railway operations required a perfect alignment of sociopolitical, technological, and environmental pieces. The material structure of the railway alone was insufficient to achieve the production of safe, speedy, and stable movement of trains. Seeing speed as corruptible through human behavior and perfectible through human endeavor, technocrats of the IRO and the Allied forces tried to contain its danger by reforming the embodied practice of movement among workers. They enacted safety regulations and sought standardization in many realms, specifying mundane physical motions of workers for particular procedures. The chapter also suggests that workers were not passive objects of reform but used their knowledge of the infrastructural system for goals different from those of technocrats.

Full textAbstract:
In this chapter, a numerical investigation is presented in order to highlight the effects of outdoor wind on smoke movements along a corridor in a compartment. For this, the Computational Fluid Dynamics (CFD) code, fire dynamics simulator (FDS), was used to model the reactive flows in interaction with outdoor wind. The wind velocity is taken between 0 and 12.12 m/s, based on the experimental result data come from the work of Li et al. was performed. From numerical data, it was found that smoke stratification state in the corridor depends on Froude number (Fr) and it can be divided into three cases: stable buoyant stratification (Fr < 0.38), unstable buoyant stratification (0.38 ≤ Fr < 0.76), and failed stratification (Fr ≥ 0.76). When Fr ≥ 0.76, smoke stratification is completely disturbed and smoke occupies the entire volume of the compartment, highlighting a risk of toxicity to people. Indeed, it was observed that the velocity of the outdoor wind influences strongly the concentration of O2, CO2, CO, and visibility in the corridor and smoke exhaust. Moreover, for the input data used in the numerical modelling, the global sensitivity analysis demonstrated that the main parameters affecting the smoke temperature near the ceiling are the mass flux of fuel and the activation energy.

Full textAbstract:
The Alameda Corridor rail project became a tale of two cities: Los Angeles and Long Beach, California. It started as a story including each of the six cities in between. The Alameda Corridor Transportation Authority transformed a tangled web of rail lines, each owned and operated by three competing railroads, into one line. The new corridor created public value in eliminating grade rail crossing that backed up truck and car traffic in six mid-corridor cities, and through the reduction of air pollution emissions and groundwater contamination. The line moved the harbours from reliance on nineteenth-century rail technology to a twenty-first-century system aligned with the technology needed to compete in a globalized goods movement world. Public expense was significantly reduced as the line was built primarily with private sector debt financing, which was paid off by fees on private sector container cargo. The move to governance by only the cities of Long Beach and Los Angeles contained costs and kept the project on time to reduce the financial uncertainty that would have adversely affected the costs of borrowing. This efficient decision-making structure based on those with a financial stake in cost containment came at the expense of participation in decision-making by mid-corridor cities.

Full textAbstract:
Although the Trans-European Transport Network (TEN-T) has made a considerable contribution to increasing transport infrastructure and improving transport services, it still often seems that border regions have reduced accessibility compared to central regions. The Iberian border regions of Alto-Alentejo (Portugal) and Badajoz (Spain) were analyzed. Studies conducted in the Iberian territories confirm some of these regions’ unsustainability and the non-impact on the inhabitants’ quality of life. Also, a few questions arise: Can we verify the change in methods and measures used by development strategies? Is it necessary to acquire a more comprehensive view of corridor flows and interactions through common regional development strategies for managing development corridors? Will we influence the change of the methodological approach to be strategic and that it does not imply a corridor only in terms of the flow and mobility of people and goods, but also the search for the causes of movements in growth corridors? So, infrastructure and connectivity planning, regional economic development, and land use planning are critical contexts in developing territorial policies in the planning of development of corridors and their integration into development processes. This study proposes a framework for strategic corridor governance to increase accessibility and regional equity.

Chapter 4 addresses the issue of human migration and mobility at the Classic period Maya site of Yaxuná, Yucatán, Mexico, located in the Maya northern lowlands, from the combined lens of bioarchaeology and archaeometry, specifically dental morphology and strontium and oxygen isotopes. The site is positioned at a crucial point of an east-to-west inland trade corridor, and the architectural evidence shows influence of the Puuc region, situated in the westernmost side of the peninsula. Given that material culture and ideas can be exchanged with or without the actual movement of people, the chapter evaluates the hypothesis that people from the Puuc region might have migrated to the city during the eighth century AD.

This chapter describes overland trade between Pakistan and China since 1969 until the present. Overland trade between the two countries takes place over the high-altitude Karakoram Highway, connecting Pakistan’s mountainous Gilgit-Baltistan region to the Xinjiang Uyghur Autonomous Region in western China. The Karakoram Highway is popularly described as a contemporary silk road; this idea has been reinforced by the 2013 announcement of the One Belt One Road initiative, which includes the China-Pakistan Economic Corridor. In this chapter, I explore the relationship between a documented, regulated silk route trade and its shadows; shadows take the form of traditional pathways between the two countries that are no longer used, as well as the undocumented movement of licit goods and smuggling of illicit substances.

Full textAbstract:
The railroad tie is an important component in track structure which provides lateral resistance, continuous support for rail and transfers the train load to ballast. The movement of the tie subject to train loading is usually considered as a vertical motion. However, it is believed that the real-world tie movement is not only translational but rotational due to moving load. In order to investigate the real movement of railroad ties, a train-track interaction computer program was used. The computer program includes a vehicle dynamics model and 3-D Finite Element (FE) track model. The wheel-rail contact forces were obtained from the vehicle dynamics model, and then input to FE track model to simulate the tie movement. Furthermore, the field validation was conducted at Northeast Corridor (NEC) in United States. The measuring units were mounted on the edge of ties to record the angle and acceleration change of the tie in three orthogonal directions. The data analysis showed that the field-measured translational and rotational movement of ties have good agreement with the simulation results. It is concluded that the tie movement is not only up-and-down motion under moving train load, but also comprises rotation and lateral movements.

Full textAbstract:
Railway transitions like bridge approaches experience differential movements related to differences in track system stiffness, track damping characteristics, foundation type, ballast settlement from fouling and/or degradation, as well as fill and subgrade settlement. A recent research study at the University of Illinois has used advanced geotechnical instrumentation to identify and quantify different factors contributing to recurrent differential movement problems at three different bridge approaches along Amtrak’s Northeast Corridor (NEC) near Chester, Pennsylvania. Field instrumentation data have indicated excessive ballast movement to be the primary factor contributing to the “bump” development at these bridge approaches. Among the different remedial measures applied to mitigate the recurrent track geometry issues were: (1) Chemical Grouting, (2) Stone Blowing, and (3) Under-Tie Pads. This paper will discuss the implementation methods using track geometry records and instrumentation data, and highlight the effectiveness of chemical grouting and stone blowing to mitigate the differential movement problem at railroad bridge approaches. According to the trends in the transient ballast deformation data collected under train loading, both remedial measures were effective in significantly reducing excessive ballast deformation, which was the primary mechanism behind the bump development at these locations. Ballast degradation and presence of excessive fine particles in the ballast layer adversely affected the ability of the grout to bond with aggregate particles. A “clean” ballast layer, on the other hand, facilitated adequate bonding between the grout and ballast particles leading to significantly improved long-term track performance.

Full textAbstract:
The increasing movement of people and products caused by modern economic dynamics has burdened transportation systems. Both industrialized and developing countries have faced transportation problems in urbanized regions and in their major intercity corridors. Regional and highway congestion have become a chronic problem, causing longer travel times, economic inefficiencies, deterioration of the environment and quality of life. Congestion problems are also occurring at airports and air corridors, with similar negative effects. In the medium distance travel market (from 160 up to 800 km), too far to drive and too short to fly, High Speed Rail (HSR) technology has emerged as a modern transportation system, as it is the most efficient means for transporting large passenger volumes with high speed, reliability, safety, passenger comfort and environmental performance. HSR system’s feasibility will depend on its capacity to generate social benefits (i.e. increased mobility rates, reduced congestion, capacity increase and reduced environmental costs), to be balanced with the high construction, maintenance and operational costs. So, it is essential to select HSR corridors with strong passenger demands to maximize these benefits. The first HSR line was Japan’s Shinkansen service, a dedicated HSR system, between Tokyo and Osaka, launched in 1964, which is currently the most heavily loaded HSR corridor in the world. France took the next step, launching the Train à Grande Vitesse (TGV), in 1981, with a dedicated line with shared-use segments in urban areas, running between Paris and Lyon. Germany joined the venture in the early 1990 with the Inter City Express – ICE, with a coordinated program of improvements in existent rail infrastructure and Spain, in 1992, with the Alta Velocidad Espanola – AVE, with dedicated greenfield lines. Since then, these systems have continuously expanded their network. Currently, many countries are evaluating the construction of new HSR lines, with European Commission deeming the expansion of the Trans European Network as a priority. United Kingdom, for example, has just awarded construction contracts for building the so called HS2, an HSRexpanded line linking London to the northern territory. China, with its dynamic economic development, has launched its HSR network in 2007 and has sped up working on its expansion, and currently holds the highest HSR network. United States, which currently operates high speed trainsets into an operationally restricted corridor (the so called Northeast Corridor (NEC), linking Washington, New York and Boston), has also embarked into the high speed rail world with the launch of Californian HSR Project, currently under construction, aimed to link Los Angeles to San Francisco mega regions, the ongoing studies for Texas HSR project, to connect Dallas to Houston, into a wholly privately funding model, as well as studies for a medium to long term NEC upgrade for HSR. Australia and Brazil are also seeking to design and launch their first HSR service, into a time consuming process, in which a deep discussion about social feasibility and affordability is under way. This work is supposed to present an overview of HSR technology worldwide, with an assessment of the main technical, operational and economical features of Asian and European HSR systems, followed by a snapshot of the general guidelines applied to some planned HSR projects, highlighting their demand attraction potential, estimated costs, as well as their projected economic and environmental benefits.

Full textAbstract:
Land disturbance associated with the progressive expansion of a major pipeline and power corridor, along with extensive timber harvesting, triggered the reactivation of an ancient, 100 million cubic meter deep-seated landslide in northern Alberta. The landslide threatened six major transmission pipelines, and caused a loss of containment in one of the pipelines. The level of landslide activity and associated pipeline damage was surprising given the relatively subtle disturbances in relation to the massive scale of the slide. Given the very shallow 4.5 degree slope inclination and the lack of any surface expression of distress over most of the slope area, this case history underscores the importance of considering regionally specific geological conditions within pipeline geohazard evaluations. An intensive, multi-pronged program was adopted to stabilize and manage the landslide, including a series of targeted surface and ground water control measures that produced an approximate 100-fold reduction in movement rates. This demonstrates that the sensitivity of slides in the region to subtle changes is a negative factor for triggering landslides, but can also be a positive factor for stabilizing them.

Full textAbstract:
As with most highway bridges, railway transitions experience differential movements due to differences in track system stiffness, track damping characteristics, foundation type, ballast settlement from fouling and/or degradation, as well as fill and subgrade settlement. This differential movement is especially problematic for high speed rail infrastructure as the “bump” at the transition is accentuated at high speeds. Identification of different factors contributing towards this differential movement, as well as development of design and maintenance strategies to mitigate the problem is imperative for the safe and economical operation of both freight and passenger rail networks. This paper presents the research framework and preliminary findings from a recently initiated research effort at the University of Illinois at Urbana-Champaign. Aimed at developing design and repair techniques to mitigate differential movement at railway transitions, this research project involves instrumentation, performance monitoring and numerical modeling of new and existing track transitions.

Full textAbstract:
In metropolitan areas, when a highway underpass project is being planned to go beneath an existing railway corridor, there are a number of concerns that could have an impact on the project. For example, will the underpass construction impact the existing railway operations? How to maintain the construction safety in both rail and highway operations? This paper brings construction technology using I-girder systems to provide a solution for highway underpass projects constructing beneath the existing rail corridors. The I-girder systems have been proved as a reliable method for highway underpass construction without the interruption of railway operations. This type of I-girder systems has been widely used in several countries as a temporary “bridge” structure in support of dynamic rail movements during underpass construction. Depending on the spans of underpass structures, a contractor can decide the number of I-girder units to be assembled and installed on site. This paper describes the construction procedures of the I-girder systems installation and daily inspection processes. A case study is used to demonstrate the applicability of I-girder systems in ensuring underpass construction smoothly while maintaining existing railway operations in a safety manner. During the construction of underpass, the contractor encountered geotechnical issues that had a severe impact on the construction safety and the integrity of foundation. This paper further discusses strategies that were used to mitigate the potential building collapses and foundation failures. It is concluded the method of I-girder systems is capable of supporting railway dynamic movements during highway underpass construction.

Full textAbstract:
Spectra Energy Transmission (SET) owns and operates approximately 6,000 kms of raw and sweet natural gas transmission pipelines in northeastern British Columbia and northwestern Alberta. This geographic area is very susceptible to landslides and unstable land mass due principally to the local geological regime. These slope instabilities present long term operational challenges to pipeline companies. Geotechnical pipeline failures are not uncommon and pipeline operators spend significant portions of their operational budgets on geotechnical issues. SET has developed a geotechnical integrity program to take a proactive approach to these geotechnical issues. Ground movement monitoring is a significant component of this integrity program and provides physical data that becomes the backbone of remedial works. SET currently utilizes traditional slope indicators, surface survey monitoring, differential GPS, LiDar and InSar technologies to obtain this ground movement data. As an element of the geotechnical integrity program, SET utilizes fiber optic sensors to monitor the pipeline’s reaction to ground movement. After the initial installation of these fiber optic sensors, it was apparent that they could be bonded to almost any structural member. Potential to use the fiber optic sensors to extend the life of a traditional slope indicator was discussed with the sensor manufacturer and six joints of slope indicator casing were fitted with fiber optic sensors. These instrumented joints were then installed across known slide surfaces at various existing monitoring locations. Periodic data collection of both the slope indicator and the fiber optic sensors allowed for ground movement correlation up to the shearing of the slope indicator. It is anticipated that with proper installation and further design improvements from the manufacturer that the fiber optic instrumented slope inclinometers will facilitate ground movement monitoring beyond the life of the traditional slope indicator. This paper discusses the results of the initial trial, what was successful, what lessons were learned, and which pipeline scenarios would benefit from this technology and potential methodologies to monitor ground movement and pipeline bending concurrently.
