| Abstract: | The paper develops a traffic network data-collecting system （TNDCS） based on CAN-BUS embedded in MC9S12D64 processor. Corresponding interface circuit is designed, and special communication application protocol is developed for TNDCS. For data processing, median filter algorithm is adopted, and CAN-BUS data communication software is developed. The testing results showed that functions and performance of the system have fulfilled the requirements, and can realize automatic acquisition and processing of regional road traffic data. |
