Patent ID: 8842023

Claim:
A vehicle detector with bicycle detect and discrimination capability comprising: an oscillator adapted to be coupled to a loop adjacent an intersection; a memory; and a processor operatively coupled to said oscillator and said memory, said memory having machine readable code stored therein, said machine readable code configured to enable said processor to activate said oscillator to produce a signal for said loop, to implement a loop cycle counter for counting a predetermined number of loop oscillator cycles defining a sample period, to implement a sample counter for accumulating sample counts N during said predetermined number of loop oscillator cycles; to implement a reference counter for storing a reference count R based on the accumulated sample counts from a previous sample period; to implement an evaluation unit for determining from the sample counts N and the reference count R whether a vehicle has entered the loop during the sample period and for determining from the sample counts N and the reference count R whether a detected vehicle is a bicycle; and to implement a Call signal generator for generating a Call signal when the evaluation unit has determined that a vehicle has entered the loop during the sample period.
