Network location models comprise one of the main categories of location models. These models have various applications in regional and urban planning as well as in transportation, distribution, and energy management. In a network location problem, nodes represent demand points and candidate locations to locate the facilities. If the links network is unchangeably determined, the problem will be ...

In developing countries, whereas the urban bus network is a major part of public transportation system, it is necessary to try to find the best design and routing for bus network. Optimum design of school bus routes is very important. Non-optimal solutions for this problem may increase traveling time, fuel consumption, and depreciation rate of the fleet. A new bus routing problem is presented i...

Project Summary The recent loss of lives, and traffic jams stretching for tens of miles as hurricanes Rita and Katrina approached the Gulf Coast demonstrate the enormous difficulty of evacuating urban areas. Mass evacuations are among the most difficult problem areas in Transportation Science because they violate key assumptions underlying traditional theories, e.g., Wardrop equilibrium among s...

The modelling of land use change is a way to analyse future scenarios by modelling different future pathways. This study demonstrates the potential to explore and test the understanding of land use change relations by applying spatial data of different scales, coupled with socio-economic data. In the EU-FP7 research project PASHMINA (Paradigm Shift modelling and innovative approaches), three st...

Rapid urbanization places increasing stress on already burdened transportation systems, resulting in delays and poor levels of service. Billions of spatiotemporal call detail records (CDRs) collected from mobile devices create new opportunities to quantify and solve these problems. However, there is a need for tools to map new data onto existing transportation infrastructure. In this work, we p...

Transportation and its environmental impacts are a major component of urban environmental management. At the same time, transportation and mobility are an important part or urban economics and the quality of life. To analyse urban transportation and its environmental impacts, a comprehensive, interdisciplinary approach is needed. No single model can cover the range of spatial and temporal scale...

Decision making on the selection of transportation infrastructure projects is an interesting subject to both transportation authorities and researchers. Due to resource limitations, the selected projects should then be scheduled during the planning horizon. Integration of selecting and scheduling projects into a single model increases the accuracy of results; however it leads to more complexity...

one of the main challenges facing urban planning in the late 20th century is the growth rate of traffic that influences access to sustainable urban development. one of the solutions proposed for traffic—as well as the economic, social, and environmental problems originating from it—in large cities has been the applying of traffic restrictions during certain times and in specific places in order...

Urban transportation is a complex phenomenon. Since many agents are constantly interacting in parallel, it is difficult to predict the future state of a transportation system. Because of this, optimization techniques tend to give obsolete solutions, as the problem changes before it can be optimized. An alternative lies in seeking adaptive solutions. This adaptation can be achieved with self-org...

Establishing a network of transit routes with satisfactory demand coverage is one of the main goals of transitagencies in moving towards a sustainable urban development. A primary concern in obtaining such anetwork is reducing operational costs. This paper deals with the problem of minimizing construction costsin a grid transportation network while satisfying a certain level o...
