Intelligent transportation clouds could provide Services such as autonomy, mobility, decision support and the standard development Environment for traffic management strategies, and so on. With mobile agent technology, an urban-traffic management system based on Agent-Based Distributed and Adaptive Platforms for Transportation Systems (Adapts) is both feasible and effective. However, the large-...

Each person who travels in a city wants to arrive to the destination as quickly as possible. Nevertheless, in the same time, from an urban transportation company’s perspective, it is also very important to assure that the access to public transport services is available for as many people as possible, according to their needs. In this paper, we try to present a model of public urban transport o...

Background: Older adults in rural areas have unique transportation barriers to accessing medical care, which include a lack of mass transit options and considerable distances to health-related services. This study contrasts non-emergency medical transportation (NEMT) service utilization patterns and associated costs for Medicaid middle-aged and older adults in rural versus urban areas. Methods:...

With regard to digital services access, many rural and remote urban area in developing countries are underserved, if served at all. In a monopolized environment, telecommunications are of low quality and costly. Broadband Internet and other digital services are restricted to small percentage of people. In some cases the operator prefers to pay fines instead of providing services to remote areas...

In this work we present a large scale static, deterministic mixed inter linear programming model (MIP) solving an integrated location-routing problem (LRP) in the context of urban logistics services (ULS). We aim at determining a cost optimal infrastructure and fleet design for an urban consolidation and transportation network. The model is meant to quantitatively evaluate potential strategic m...

Brent D. Ryan first visited Detroit in 1993. Describing this experience, he says: ‘‘The sense of emptiness was overpowering. ... I felt as if I was walking into the ruin of America.’’ In his book ‘‘Design after decline—how America rebuilds shrinking cities,’’ Ryan tries to understand why so many American cities have been losing population, what was and is done to change the fortune of these cit...

In China, rapid economic growth and increasing foreign direct investment (FDI) is the driving force for urbanization, and transformation of urban spatial structures and transportation. Frequent interactive economic activities among the neighboring cities reinforce the already spatially clustered cities. In this paper we tried to extract the key urban transportation characteristics of seventy ma...

Increasing pressures caused by negative consequences of transportation and traffic problems in major cities, have resulted many attempts towards improvement of planning and management of transportation systems, according to sustainability objectives. In this paper, a comprehensive model is developed using a system dynamics approach to evaluate sustainable urban transportation. This model includ...

This paper proposes a new microfoundation for the existence of dense urban areas. Proximity between consumers and service providers in dense areas facilitates demand for market services due to a low time cost of purchasing services. Urban residents share the factor inputs used to produce services by purchasing on the market the services that their suburban counterparts produce at home. The mode...
