Oftentimes intelligent transportation systems (ITS) is perceived as cutting-edge technology that will become fully realized in the near future. One aspect of ITS, mayday technologies, has already arrived. From commercial products backed by large automobile manufacturers [such as GM OnStar (Trademark) and Ford Rescu (Trademark)] to aftermarket products [such as CERES (Trademark) and AutoGuard (Trademark)], these technologies are being equipped in consumer vehicles across the nation. In an effort to determine the impact of emergency calls from such systems, the Minnesota Department of Transportation (Mn/DOT), Minnesota State Patrol 2100 (MSP), and Mayo Emergency Communications Center (MEC) have teamed up with Veridian Engineering to develop an emergency communications infrastructure capable of directly accepting mayday calls and intelligent enough to accurately route calls to the proper authority depending on the geographic location and the nature of the incident. The Mayday Plus system consists of the in-vehicle module (IVM), dispatcher interface and communications gateway. The IVM consists of cellular and global positioning system (GPS) technologies and is capable of transmitting voice, location, and crash severity data. An example of crash severity data includes the change in velocity of the vehicle upon impact. The dispatcher interface is a personal computer that displays data received from the vehicle or other dispatch centers interconnected to the Mayday Plus system. The communications gateway is the key to the Mayday Plus system. The gateway automatically and logically routes data and voice based on the geographic location and the nature of the incident. The Mayday Plus equipment has been installed in test vehicles in the Rochester, Minnesota area. This paper reports the findings of the six-month Mayday Plus operational test. |
