Wireless Sensor Networks (WSN) provide an economical, convenient alternative solution to existing traffic monitoring systems, such as video recognition and inductive loops. However, there are many technical challenges in on-road real-time traffic infor- mation collection with WSN, e.g. accurate vehicle detection in low Signal-Noise-Ratio (SNR) conditions and reliable vehicle speed calculation. In this paper we propose a sys- tematic solution to on-road real-time traffic monitoring with a magnetic sensor network. We propose a Similarity Based Vehicle Detection (SBVD) algorithm to detect vehicles in low SNR conditions by calculating the similarity between on-road signals and a ref- erential signal. We propose a Collaborative Speed Calculation (CSC) mechanism to cal- culate vehicle speed reliably by redundant nodes and accurate reports of vehicle appear- ance. The CSC mechanism can calculate vehicle speeds accurately and trustworthily. We demonstrate through simulations and experiments that our proposed solution works ef- fectively in noisy on-road environments. The vehicle detection rate is above 90% while no false alarm occurs and the error rate of speed calculation is under 10%.
