The real-time measurement and analysis of various road traffic parameters such as vehicle count, speed of vehicles, type of vehicles, and the turning movements of vehicles at traffic junctions (TMJ) etc. are increasingly required for traffic control and management. The image processing technique is now considered as an attractive and flexible technique for automatic analysis and data collection in traffic engineering. However, the computational requirement for such a technique is beyond the capacity of conventional computers, therefore, special purpose architectures have to be designed to speed up image processing operations. In this paper we describe a programmable image processor for measuring road traffic parameters such as vehicle count and TMJ parameters. The processor is designed with a high degree of parallelism to speed up image processing operations. Combining data parallelism found in array processors into the architecture of the processor, a high degree of concurrency is achieved. The processor is modelled and simulated using VHDL language. We execute image-processing algorithms on the simulation model and measure the performance of the whole system. The results show that the system is able to measure traffic parameters in real-time.
