Automated Red Light Camera Impact Conducted an evaluation of automated red-light cameras and their impact on red light violations for the Insurance Institute for Highway Safety. Ten sites fitted with automated red light cameras (as well as a number of sites without cameras) were monitored for incidence of red light violations before and after installation of the cameras. A 40% reduction in violations and accidents at intersections was documented.

Intersection Evaluation for Red Light Camera Deployment Evaluated potential installation sites for automated red-light cameras for US Public Technologies and Lockheed Martin. Candidate intersections were scouted and filmed unobtrusively for extended periods. Traffic volumes and red-light violation rates were calculated. Recommendations concerning the economic viability of instrumenting intersections based upon the violation rates were provided.

Field Test of Speed Adaptation Theory Conducted a re-test of the speed adaptation theory for the Insurance Institute for Highway Safety. Speeds of approximately 3,000 vehicles traveling on selected freeways and connecting roads in California were obtained by researchers using radars, clocks, and radios. The results were compared to an identical study conducted two years previously at the same sites.

Mobile Roadside Speedometer Conducted a field evaluation of the Mobile Roadside Speedometer. Over 100,000 vehicles were monitored by trained observers to asses the impact of large roadside speedometers on vehicular speed. Thirteen different sites were studied over a period of six months. Overall impact of the device on speed, adaptation to the device, deployment schedules, and coupling with enforcement by police were all examined.

Acceptable Deceleration Rates While Standing Conducted an extensive review of existing research, standards, and guidelines on acceleration and deceleration rates experienced in everyday transportation settings, including trains, streetcars, moving walkways, escalators, and high-speed rail. The results were summarized and illustrated for the client, a manufacturer of heavy equipment.

Red Light Violation Rates Conducted a video study of eight intersections in the City of Santa Barbara to determine red light violation rates. Tens of thousands of vehicles were monitored and all violations were documented and analyzed. Based on the violation rates, the City determined that instrumentation of the intersections with automated red light cameras would not be a cost-effective enforcement solution.
