The solution implemented was designed to link Connected Vehicles to roadside units (RSUs) and intersection controllers, and then transmit the data to transportation management centers (TMCs). The data collected included ambient temperature, surface temperature, humidity, barometric pressure, and dew point along with other vehicle data such as position, speed, and acceleration.
The size and scope of coverage was limited by requirements to have line-of-sight (LOS) Dedicated Short-Range Communications (DSRC) communications between vehicles and RSUs as well as the ability of the system to quickly process and transmit data to back-office systems.
The project demonstrated the viability of using Connected Vehicle systems and data to identify weather related threats and hazards. Combining this information with other fixed and mobile data can provide the additional coverage and details needed to ground truth local data during weather events.
