OPTIMIZATION OF GRID TRANSIT SYSTEM IN HETEROGENEOUS URBAN ENVIRONMENT

Current analytic models for urban transit system optimization often sacrifice geographic realism and detail to obtain solutions. The authors present an optimization model that can be successful without oversimplifying the spatial characteristics and demand patterns of urban areas. This model is designed to optimize a grid transit system in a heterogeneous urban environment whose demand and supply characteristics may vary arbitrarily among adjacent zones. Network characteristics and operating headways are found that minimize the total cost, including supplier and user costs. Irregular many-to-many demand patterns, zonal variations in route costs, and vehicle capacity constraints are taken into consideration in a sequential optimization process.
