Distributed Surveillance and Control on Freeways

The report develops a new approach for reducing the required communications network and transmission costs at loop detector stations. The approach is a decentralized, event-driven surveillance system. Using the approach, the first step of the decision-making process is distributed from the central system to the field sensors. An analytical methodology is presented for increasing the accuracy of speed estimates from freeway traffic detectors by integrating information across lanes. The report focuses on the communications methodology and quantifies potential costs using empirical data.
