Study on the optimal detector location for the active bus signal priority of the median bus lane

In this study, the bus waiting time at signalized intersection for the active bus signal priority was modeled according to the detector location, and this model can determine the detector location for the minimum bus delay. With the application of the various bus speed and detector location, this study analyzed the change of bus delay. In addition, this study analyzed the active bus signal priority using a microscopic simulation under the same conditions with the analysis of bus waiting time. The result of microscopic simulation using VISSIM also showed the similar trend with the results from the waiting time model. This research made sure that the bus delay can be changed according to the detector location only, even if the delay of passenger car had a slight change.
