Abstract:Despite the emergence of many new mobility options in cities around the world, fixed route transit is still the most efficient means of mass transport. Transit efficiency, however, is well known to be interdependent with ridership demand and network design. As a result of this interdependency, bus operations are subject to vicious and virtuous cycles. Intervention is required to promote a virtuous cycle and make the bus more competitive, especially in the face of increased competition from ride-hail services. This can be done by redesigning the bus network in a way that does not increase operating cost while reducing user costs and increasing accessibility for more riders. The research challenge lies in having an easy-to-use methodology to evaluate and compare two or more transit network designs in which one or more designs may be incomplete; i.e. only includes route alignments without either stop locations and/or service frequencies. This study addresses these gaps by presenting a systematic process that combines techniques from both analytical and simulation-based tools: (1) Given a route data set, use analytical route-level modeling to identify stop locations and/or frequency to minimize cost (both user and operator); (2) Create a General Transit Feed Specification (GTFS) schedule from the output of the analytical model; and (3) Use a multi-agent simulation model to derive the equilibrium for the network design. There is no commercial tool that combines all three of these methods together. The objective of the project was to put these steps together and show how it can provide insightful decision support to transit planners that these tools alone do not provide.
