Abstract

In a method for calculating a location of a traffic incident a processor receives a first alarm message. The alarm message has a device identification, an event time stamp indicating detection of an incident, and a first distance vector. The processor calculates first isodistance information from the first distance vector and receives a second alarm message that has the device identification, the event time stamp, and a second distance vector. The processor calculates a second isodistance information for the second alarm message, and calculates a location of the incident based on the first isodistance information and the second isodistance information.
