• Abstract:
  High quality vehicle detection is essential to properly operate actuated phases at traffic signals and to facilitate effective ; management of technician and engineering resources. INDOT operates over 2600 traffic signal controllers, approximately 2000 of ; which use some form of vehicle detection. The private sector continues to develop innovative sensing technologies that may ; potentially benefit Indiana motorists and taxpayers by improving system efficiency and lowering installation and maintenance costs. ; However, the acceptance of new sensing technology requires careful evaluation because to ensure that they provide robust ; performance 24 hours a day, 365 days a year, with minimal impact on maintenance resources. ; This study developed a technical protocol for evaluating vehicle detector performance and applied those techniques to both video ; detection (in partnership with Texas) and wireless magnetometers. Based on experiences in designing the detector test bed, ; recommendations are given for stop bar detection zone design using wireless magnetometers. Additional results include a detailed ; study of the inductive loop detector sensing range for several loop geometries, and an innovative method for interrogating NTCIPcompliant ; traffic signal systems to allow quality control on signal timing plan implementation. Since this project spanned several ; years, interim results were documented in the professional literature as they became available. This technical report summarizes ; those results and provides references to the published papers.
