| Abstract: | This paper introduces the theory of vehicle speed detection based on loop coil, analyzes the present speed estimation methods using the basic outputs of single loop detectors. On this basis, a real time vehicle speed detection algorithm based on single loop detectors is presented and a loop coil detector system is designed as well. Through obtaining data from this detector system, the simulation of this algorithm is realized using the Matlab6. 5 software. The simulation results prove that this algorithm basically meets the design requirement. |
