A study of the feasibility of using photo-radar for traffic speed enforcement in Virginia / by Lynn, Cheryl.(CARDINAL)311173; Virginia Transportation Research Council.(CARDINAL)195142;
Includes bibliographical references (pages 18-20).Final report.Because of increasing difficulties in enforcing posted speed limits on the Capital Beltway around Washington, D.C., local officials proposed that experiments be conducted with photo-radar to determine if that method of automated speed enforcement (widely used in Europe for about 30 years and very recently employed in the western United States) could help reduce average speed and speed variance. A project task force led by the Virginia Department of State Police, with assistance from the Maryland Department of State Police and the Virginia and Maryland Departments of Transportation, and with technical assistance from the Virginia Transportation Research Council, conducted site visits to cities in Europe and the United States where photo-radar is being used. The task force also invited six manufacturers of photo-radar equipment to staff and demonstrate their equipment. Five of the manufacturers conducted a 2-week series of tests on sections of interstate highways with varying volumes of traffic and different traffic characteristics. The tests, which were conducted from June through September 1990, were designed to provide the evaluators with data on the accuracy, reliability, and efficiency of each unit (in terms of the number of speeding cases that could potentially be generated by the use of photo-radar on the Beltway) and help the study team determine if photo-radar could be successfully deployed on the Capital Beltway as an enforcement tool. In addition, the project included an analysis of legal and constitutional issues associated with photo-radar use as well as an evaluation of public sentiment concerning photo-radar use on the Capital Beltway. The evaluators concluded that photo-radar use was feasible on high-speed, high-volume roads such as the Capital Beltway and, therefore, recommended efforts to pass state enabling statutes and test further the efficacy of photo-radar in actual traffic enforcement conditions.Sponsored by Virginia Department of Transportation, University of Virginia, [and] Virginia Dept. of State Police, under a grant awarded by the National Highway Traffic Safety Administration, contract no.

Automated speed enforcement pilot project for the Capital Beltway : feasibility of photo-radar / by Lynn, Cheryl.(CARDINAL)311173; Virginia Transportation Research Council.(CARDINAL)195142;

Although the results of the study indicate that it is feasible to use photo-radar on high-speed multilane roadways, further study is required to determine its effect on travel speed and safety. There are also important operational issues that must be considered when using this device. Some items of consideration are identification and selection of operational sites and times to deal with identified traffic safety and enforcement problems; provision of equipment-specific training programs for police officers to ensure the equipment is properly operated; provision for the availability of properly trained technical support personnel to ensure the continuing accuracy of the equipment; setting of speed thresholds that are realistically determined and target the excessive speeder; number of lanes on the roadway; visual obstructions on the roadway; and customizing of photo-radar applications to fit the highway safety problem area.Sponsored by Virginia Department of Transportation, University of Virginia, [and] Virginia Dept. of State Police, under a grant awarded by the National Highway Traffic Safety Administration, contract no.

Impact of the 65 mph speed limit on Virginia's rural interstate highways, 1989-1992 / by Jernigan, Jack D.(CARDINAL)311176; Lynn, Cheryl.(CARDINAL)311173; Strong, Sarah E.(CARDINAL)314590; Virginia.Department of Transportation.(CARDINAL)291718; Virginia Transportation Research Council.(CARDINAL)195142;
Includes bibliographical references (pages 19-20).Final report;In April of 1987, Congress passed the Surface Transportation and Uniform Relocation Assistance Act (STURAA), which permitted states to raise their maximum speed limit on rural interstate highways to 65 mph. Virginia's 65 mph speed limit went into effect on July 1, 1988, for passenger vehicles and on July 1, 1989, for commercial buses. This is the final report in a series to examine the 65 mph speed limit in Virginia, and it summarizes Virginia's experience with the 65 mph speed limit from 1989 through 1992. Following the implementation of the 65 mph speed limit, average and 85th percentile speeds increased on Virginia's rural interstates, and fatal crashes and fatalities increased significantly. On Virginia's urban interstates, on which the speed limit remained at 55 mph, there was a smaller increase in average and 85th percentile speeds, but there was a slight, nonsignificant decrease in fatal crashes and fatalities. Absolute numbers of fatal crashes and fatalities were used in this analysis rather than rates because traffic volume increases on interstates are averaged for both rural and urban systems. Thus, if volumes increased more on rural interstates, comparisons of relative rates would be misleading. The data in this report clearly show that speeds, fatal crashes, and fatalities increased on Virginia's rural interstates after the implementation of the 65 mph speed limit. However, these increases appear to have plateaued in the last two years of the study. Reports from other states and from national studies reflect a general increase in travel speeds and fatal crashes on rural interstates, but there is conflicting evidence on whether the 65 mph speed limit is the cause. Likewise, there is conflicting evidence concerning whether differential speed limits for trucks and cars have had an impact on the frequency of crashes in states maintaining such differential limits.Sponsored by Virginia Department of Transportation, the University of Virginia, [and] the Virginia Department of Motor Vehicles, with the cooperation of the Virginia Department of State Police, under project no.
