GIS for Transportation Route Optimization
Manuel MartinezYingsheng Li
This paper uses geographic information systems to locate optimal transportation networks in a continuous manner. The paper offers a special interface function written in Avenue in conjunction with an internal or external database that maximizes net social benefits and locates the route spatially based on its curvature and the laws of refraction, junction, and technical constraints. The paper visually displays the solution to the problem of connecting points by a transportation network such as the demand is met at a lowest total expense. It uses a nonlinear programming maximization program that locates a smooth curve (optimal route). The program includes the social benefits and social costs that include construction and transportation related costs. It is capable of introducing the specified criteria in major investment studies. This application converts socioeconomic and technical data to raster form. Then it assigns a vector of data to the cell. Finally, the program calculates and locates the optimal route trunk. This study uses Northern Jersey journey-to-work data to locate a hypothetical new guided-way transit and compare it with the results of an also hypothetical new highway trunk.
