An Infrastructure-less Vehicle Counting without Disruption

This paper presents a solution to count all moving vehicles in a target region. This is a large-scale counting that cannot be easily solved without a global view. However, there is no single force that can provide such a global view. To achieve an accurate result without either double- or miscounting, the local counting at each checkpoint is synchronized in our wireless communication by using the information carried by vehicles along the traffic flow. Our analytical and experimental results illustrate the correctness of the proposed scheme in both closed and open road systems - even when the wireless signal is affected by many factors. In this way, we provide an essential support for the resource management in VANETs.
