We designed a video vehicle detection system based on DM642 with embedded technology for detecting traffic flow in intelligent transportation systems. A new algorithm based on virtual loop is used to count the vehicle through the region combining vehicle speed estimation with effective statistics in this paper. And this algorithm is transformed to DM642 platform to run, the results can meet the requirement of real-time monitoring and achieve robustness for the interference of external condition changes. The experiment on the acual traffic video shows that DM642 video vehicle system can get high detecting accuracy and high stability
