Abstract
This report describes preliminary analysis of strategies to activate and deactivate
a bus pre-signal using vehicle count data. The bus pre-signal currently operates during preset times to regulate access to a length of road controlled at the other end by vehicle-actuated traffic signals. However, vehicle flows at the pre-signal vary on a daily basis so a more demand-based approach would be more effective. There has been much research performed to optimise pre-signal cycle times and bus priority at pre-signals. We focus on identifying the optimal strategy to activate and deactivate the bus pre-signal using vehicle demand rather than the current fixed time strategy. The ideal strategy should be stable, robust, consistent and timely. We investigate strategies using vehicle counts, queueing theory and estimation and prediction. Our recommended strategy combines aspects of all three areas.
