Low Cost Wireless Network Camera Sensors for Traffic Monitoring

Many freeways and arterials in major cities in Texas are presently equipped with video detection cameras to collect data and help in traffic/incident management. In this study, carefully controlled experiments determined the throughput and output quality of various communication configurations. Configurations entailed antennas at several cost levels and it was determined that the least expensive antennas were adequate only for one-hop systems. Via a survey to which 20 districts responded, incidents, volume, and speed were found to be the functionalities most in demand for autonomous surveillance systems. Most systems are monitored by human operators. An alternative to operator-based video monitoring is video analytics. An autonomous traffic monitoring system from a vendor was tested. A demonstration surveillance system was developed and delivered to the Texas Department of Transportation.
