Sustainable transportation for Indian cities: role of intelligent transportation systems
This article highlights the relationship between sustainability (or maintainability) and efficiency of transport systems. It also outlines some of the problems and issues that exist in providing mobility to urban Indians. Finally, it enumerates some of the ways in which application of (modern) information and communication technologies can help improve the efficiency of the transportation syste...
متن کاملOptimal transportation and the structure of cities
Following the recent analysis of Lucas and Rossi-Hansberg [10], we study the equilibrium structure of cities. By adopting a different (monetary) specification of commuting costs, we are able to prove the existence of equilibrium in more general situations: non-circular cities, or multi-sectorial production. The main mathematical tool in this paper is the use of optimal transportation theory. Th...
متن کاملThe Full Cost of Transportation in the Twin Cities Region
The goal of this work is to calculate the full costs of transportation for autos, trucks, and buses in the Twin Cities region for the years 1998 and 2020. Our midrange estimate is that the costs were $27 billion in 1998, and the costs will grow to $42 billion in 2020 ($9,000 and $11,200 in per capita terms, respectively). These estimates include monetary and nonmonetary costs to individuals, fi...
متن کاملIntelligent Data Transportation in Smart Cities: A Spectrum-Aware Approach
Communication technologies supply the blood for smart city applications. In view of the ever increasing wireless traffic generated in smart cities and our already congested radio access networks (RANs), we have recently designed a data transportation network, the vehicular cognitive capability harvesting network (V-CCHN), which exploits the harvested spectrum opportunity and the mobility opport...
متن کاملThe Design of a Letter-Mail Transportation Network by Intelligent Techniques
Many transportation providers such as package delivery companies and postal service organizations face the problem of designing a transportation network in order to service their customers. This network must balance the requirement of on-time delivery under tight time window constraints with the goal of low-cost operations of the fleet. Until recently this task was usually performed by planners...
