Procurement Procedures and Specifications for Performance Measure Capable Traffic Infrastructure Data Collection Systems

Traffic signal systems represent a substantial component of the highway transportation network in the United States. Unfortunately, most agencies struggle to meet the challenge of finding enough resources to properly update signal policies and timing plans to accommodate changing traffic demands. The traffic engineering community has been aware of system underperformance for several years, but most proposed solutions have been too expensive or not well enough understood to see widespread implementation. Incremental system upgrades can return some benefits, but the more fundamental problem that they do not address is that system performance information is not measured or reported in any meaningful or systematic manner.
