Abstract:

In the California Connected Vehicle (CV) Testbed, four intersections have been instrumented with NoTraffic sensors for more accurate detection of multi-modal traffic within the intersection conflict area, and six operational High Intensity Activated CrossWalK (HAWK) signals have been installed to enhance the safety for pedestrians and cyclists while crossing the major arterial, El Camino Real. In this project, efforts have been devoted to enhancing the Multimodal Intelligent Traffic Signal System (MMITSS) to support these infrastructure upgrades. To ensure the Transit Signal Priority application can function properly after the installation of HAWK signals, functions in the MAP Engine Library have been revised to allow the identification of multiple downstream intersections and the calculation of the corresponding distances and travel times. To incorporate the more accurate detection data from the NoTraffic sensors into Vehicle-to-Everything (V2X) messages, new functions have been added to the MAP Engine Library to determine the lane-of-travel for vulnerable road users and track road user movements inside an intersection conflict area. In addition, new schemes have been proposed to construct appropriate MAP and Signal Phase and Timing (SPaT) messages for the HAWK signals with different road geometry settings.
