Bus Service Design Under Demand Diversion and Dynamic Roadway Congestion Based on Aggregated Network Models

This paper proposes an integrated methodological framework to design spatial-dependent bus route network and time-dependent headways to serve travel demand that varies over time and space. Travelers choose transit or driving mode (as well as travel paths) that minimizes its equilibrium travel cost in the multi-modal network. Transit routes use dedicated bus lanes in the city streets, and hence roadway congestion (which evolves dynamically based on regional macroscopic fundamental diagrams) depends on the transit route design. The proposed modeling framework consists of a bus network optimization module that produces optimal headways and local route spacing, and a dynamic aggregated network model that determines route choice, mode split, and user equilibrium conditions for all origin-destination demands. An iterative solution algorithm is developed to solve such an integrated model. Numerical experiments are used to demonstrate the applicability of the proposed modeling framework and provide managerial insights on the influence of the demand pattern, transit network design, and roadway congestion on system performance.
