Adaptive pre-signal control at bi-modal intersections

Research output: Chapter in Book/Report/Conference proceedingChapter


In urban areas, where road space is limited, it is important to provide efficient public and private transportation systems to maximize person throughput, for example from a signalized intersection. To this end, this chapter looks at providing bus priority using adaptive pre-signals. Presignals dynamically allocate the road space upstream of bi-modal intersections. We propose an adaptive control algorithm tailored to realtime private and public transportation demands. The necessary infrastructure to operate an adaptive pre-signal is established, and guidelines for implementation are provided. It is demonstrated with case studies that, under all considered scenarios, implementing a pre-signal with the proposed adaptive control algorithm will result in the least average person delay at the intersection.
