Quantitative analysis of bus location and control

Abstract

Bus flow through a route is analyzed and modeled, and the effects of various control strategies on bus flow are measured using computer simulation. Passenger loading and unloading times are shown to be the mechanism whereby positive feedback occurs, amplifying deviations from schedule. The application of control to the route model results in a 67% reduction in the standard deviation of trip time, and a 25% reduction in passenger average waiting time.
