Our team's research in the field of traffic design and control includes road network traffic control, unconventional intersection control, bus signal priority control, pedestrian crossing traffic control, data drive and diagnosis optimization. From the traditional data environment to the holographic sensing environment and the vehicle-road networking environment, the traffic design and control scheme is optimized to achieve the best individual adaptation, optimal timing parameters, reasonable phase design, network active prevention, and the best utilization of facilities. The research contents of the five sub-fields are introduced below.
5. Data-driven and diagnostic optimization mainly includes the processing of trajectory data, the fusion of multi-source data, and the calculation of signal control level index.
