Evaluation of Different Bus Priority Functions in Coordinated Traffic Signals
2013 (English)Conference paper (Refereed)
Delay at signalized intersections is a considerable part of the journey time for public transport (PT) in urban areas, but the delay can be reduced with PT priority in the signals at a relatively low cost to other traffic. The impact on other traffic is dependent on which priority functions are used, but the effects are hard to calculate in a coordinated system and do not always act intuitively. In this paper, experiments with a microscopic traffic simulation model are conducted with a software-in-the-loop signal controller simulator to study the costs and benefits, primarily in terms of travel times for buses and other traffic, of different priority functions in the Swedish PRIBUSS method for conditional active bus priority. Based on the analysis of the different functions, new conditions for priority are proposed and tested with the microscopic simulation model.
