Travel time is important information for traffic management system, which can help people to plan their travel schedule and improve their work efficiency. The development of smart travel time information system for multiple moving vehicle detection and tracking on highway composed of an embedded Linux platform and an image sensor. A low cost system with high resources is needed to capture an image of the monitoring area, analyze it and perform the vehicle detection and tracking process of the image to estimate the speed and time taken of moving vehicle from one point to another point on the scene. So, this paper will review some of embedded board that been used with image processing to find out which kind of platform that is suitable and possible to measure and estimate the travel time.
