ABSTRACT:
A technique for operating a vehicle detection system involves obtaining samples randomly from a detector of the vehicle detection system and determining the presence of a vehicle in response to the random samples. When multiple detectors are located in close proximity to each other, the likelihood of interference caused by concurrent sampling events is reduced because of the randomness of the sampling, which in turn reduces the occurrence of incorrect vehicle detection results. Control systems for vehicle detection systems obtain the random samples independently from each other. Because the random samples are obtained independently from each other, multiple inductive loop vehicle detection systems can be operated in close proximity to each other without having to be coordinated or synchronized in any way. The possibility of an incorrect vehicle detection as a result of concurrent sampling events can be further reduced using validity checking techniques.
