Abstract

Traffic event data source identification embodiments comprise a first monitoring system that detects a traffic event, a communication device that broadcasts a discovery signal and receives back response signals from any second monitoring systems within the vicinity of the traffic event, and a memory that stores a list of responding second monitoring systems. Traffic event data collection embodiments incorporate the identification embodiments and additional features. In this case, the first monitoring system captures data recorded at the time of the traffic event and a second communication device transmits this data and, optionally, the list to a traffic event database in a traffic event data storage system. The first communication device also transmits a data capture request signal to the second monitoring system(s) requesting capture of any data recorded at the time of the traffic event and, optionally, requesting that such data be transmitted to the database.
