Abstract: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 TxDOT.
