Bus Green-Wave Band Design Considering the Factors of Queuing Delays

摘要

Bus green-wave signal control refers to the design of green wave band in accord with the running and operation characteristics of the city bus in order to reduce bus delays at the intersection. Bus green-wave signal control is usually combined with bus lane or bus-only approaches. However, due to the limitation of city road resources, bus lane or bus-only approaches cannot be set in every intersection. Without bus lane or bus-only approaches, buses will be mixed with other traffic in intersections. Therefore, bus queuing delays need to be considered when implementing bus green-wave signal control in such an intersection. The primary purpose of this paper is to develop a method to design bus green-wave band on the basis of MAXBAND model, considering the effects of intersection saturation and bus queuing delays. This study will expand the application range of bus green-wave.
