Abstract
A system and method for detecting incidents along a roadway are provided. A plurality of readers are spaced at intervals along a roadway for reading uniquely identified data from each of a plurality of vehicles. These readings are correlated to obtain information on each of the vehicles and to determine the number of vehicles potentially affected by incidents along the roadway. Finally, the number of each of the vehicles potentially affected by incidents is compared to a sample threshold in order to determine if a traffic incident has occurred.
Claims36
A method for detecting incidents along a roadway comprising the unordered steps of:
- arranging a plurality of readers at intervals along a roadway for reading uniquely identified data from each of a plurality of vehicles;
- correlating the data with previously read data to obtain information on each of the plurality of vehicles;
- determining the number of vehicles potentially affected by incidents along the roadway;
- and
- comparing the number of vehicles potentially affected by incidents to a sample threshold.
A method for detecting incidents along a roadway comprising the unordered steps of:
- arranging a plurality of traffic probe readers at intervals along a roadway for reading a transponder disposed on a vehicle;
- correlating the transponder readings from each of the plurality of vehicles and expected readings from each of the plurality of vehicles at more than one traffic probe reader;
- and
- detecting incidents which result in an interruption to the flow of traffic.
An incident detection system comprising:
- a traffic management center processor connected to a data network;
- a plurality of unique vehicle data readers connected to said data network such that uniquely identified data are read from each of a plurality of vehicles;
- a correlation processor, wherein said uniquely identified data are correlated to obtain a count of overdue vehicles and early arriving vehicles;
- and
- an incident detection processor.
