Integrative Vehicle Infrastructure Traffic System (iVITS) Control in Connected Cities

With the rapid rise in smartphones and Global Positioning System (GPS)-enabled devices, vehicles are becoming increasingly connected. Some newly manufactured vehicles are equipped with devices that provide information about vehicle characteristics such as speed and acceleration, and aftermarket devices also share vehicle data. This information in addition to that provided by road infrastructure, such as traffic signal status, weather and road conditions can be shared between connected vehicles (CVs) to enhance mobility, safety, and environmental impact. The information exchange between one or more vehicles and between vehicles and infrastructure is enabled through applications whose efficacy can be evaluated in simulation environments, representing real traffic scenarios. One of the key efforts in the CV domain is the ongoing, U.S. Department of Transportation sponsored New York City Connected Vehicle Pilot (NYC CVP). As a part of this pilot, 2000 vehicles operated by NYC government are equipped with Direct Short-Range Communication (DSRC) aftermarket devices on vehicles being operated. Infrastructure to vehicle communication is enabled by installing devices on 250 signals and the highway of Franklin D Roosevelt (FDR) Drive. To evaluate these device applications on user mobility and safety, this project developed a calibrated model of FDR. Calibration was performed using procedure elaborated in the Federal Highway Authority’s Traffic Analysis Toolkit using several different datasets such as traffic counts, travel time and traffic incidents from different sources. As the NYC CVP starts delivering data, the calibrated simulation model will be utilized to test different scenarios such as varying demand, traffic incidents, and levels of market adoption of CV technology.
