| Abstract: | An algorithm for real time extracting and describing the features of vehicle trace curves is presented. The algorithm uses Line Element as the basic unit to describe trace curves, uses trace points calculated by Dead Reckoning method as original data. The real time extracting is based on the original data. The algorithm reduces complexity, insures the real time performance. It has been used in MOTMS system, and satisfactory results have been obtained. |

| Keywords: | trace curve Dead Reckoning Line Element pattern matching. |
