Abstract

Real-world transit scheduling is complicated, with the computational burden to solve these problems increasing exponentially as the problem size increases. This paper compares a multiple depot scheduling model and two single depot scheduling models derived from the multiple depot model. The analysis is performed by solving the blocking problem for the operation of the Mass Transit Administration (MTA) in Baltimore, Maryland. Results obtained from the three models are compared with each other and the original MTA schedule. These comparisons show that a single depot vehicle scheduling model performs better under certain conditions. A sensitivity analysis with respect to two parameters, deadhead speed and maximum allowed block time, reveals that deadhead speed is an important parameter, with an increase in deadhead speed resulting in a decrease in total cost.
