Illustrating operation of the project's current automated multiple vehicle simultaneous speed measurement and display system. Each vehicle is identified as a moving object and its speed is displayed. The system counts the number of vehicle entering and leaving campus along Azalea Lane over a predetermined period of time.

Two A. James Clark School of Engineering professors have been awarded a $1M contract from the Federal Highway Administration. Professor Christopher Davis, Electrical and Computer Engineering, and Professor Stuart Milner, Civil and Environmental Engineering, will collaborate on a three year project using cooperating high definition cameras to monitor traffic characteristics, such as vehicle speeds and types, incidents, and congestion in the transportation infrastructure.

Their research project, entitled “Cooperating Camera Platforms for Ultra High Resolution Traffic Surveillance and Autonomous Event Detection,” is designed to provide much improved cooperating camera traffic surveillance. Currently, the use of cameras for this type of transportation infrastructure monitoring is proliferating at a phenomenal rate. However, the cameras are almost exclusively closed circuit television (CCTV) single cameras that may sometimes transmit live, streaming images over dedicated wired networks or the Internet, but most often, they require human monitors to detect incidents or control movement. The cameras currently used often have very low resolution or frame rates, and if they have any automatic detection capabilities, they are usually only capable of singular event detection such as stop-bar detection, counting vehicles, some type of classification, and possibly identifying accidents and vehicle speeds within a fixed area. These transmissions converge in operations centers where they rotate on multiple screens over time. In this mode, critical events can be missed if they are not viewed by an operator at the time they are displayed.

Current traffic surveillance systems almost universally use single CCTV cameras with low resolution and limited capability for analysis of real-time traffic movement patterns. This project aims to provide significantly improved cooperating high definition camera traffic surveillance. The new system will have the capability to recognize “events” in the highway infrastructure and relay this information to command centers in real time. The technology will also enable and feature extraction algorithms to interoperate with ultrahigh resolution surveillance hardware. A number of unique technologies, like cooperating camera platforms, machine vision cameras, and servo-stabilized cameras, will effectively serve multiple purposes. The use of cooperating cameras enables significant improvements in computer vision algorithms and will allow a test bed for developers of algorithms. If these systems are ultimately deployed they will allow accurate real-time control of traffic flows to alternate routes, speedier dispatch of first responders to address highway problems, and in the future possible tracking of vehicles from source to destination.

Throughout this research and upon its conclusion, this project will expand industry understanding of the advantages of ultrahigh resolution highway surveillance and real-time analysis and dissemination of detected “events” or anomalies.
