Private driver situational awareness can help avoid vehicle crashes and related injuries and deaths associated with emergency vehicles transiting to or from emergency incident locations. Developing technologies to enhance private driver situational awareness will improve driver safety and the effectiveness of emergency vehicle operations. Emergency vehicles can send out early alerts to wireless devices like GPS and smart phones of private drivers in the immediate vicinity of the first responder. To address this, IAI will develop a novel Early AleRt System for Emergency Vehicle Proximity (EARS4EVP). This system will incorporate efficient database processing and advanced communication technology to provide an integrated solution that alerts drivers of the proximity of emergency vehicles, via their personal wireless devices. A smart-phone based context-aware application will be developed to serve as a near-term solution. First responders and emergency vehicles will use it to send out early alerts to the smart phones of private drivers, from the emergency vehicle dispatch center’s real-time database server. This solution uses available technologies but users will have to register for this smart-phone based application. Further, the DOT’s Connected Vehicles (CV) technology development effort will be leveraged to develop a long-term solution. Through the dedicated short-range communication (DSRC) network, mutual wireless communication is enabled between vehicles and Road Side Equipment (RSE). This solution will allow direct inter-communication between emergency vehicles and nearby private vehicles. Nearby private vehicles with DSRC radio devices will relay messages though the RSE and other private vehicles to a certain range. No pre-registration is required and all private vehicle drivers in the proximity of emergency vehicles will be alerted.
