Lesson Learned

The traffic monitoring and data collection section was the lowest-scoring section regardless of signal system size or type of agency. Without regular traffic data collection, it is difficult for an agency to assess the need to update signal timings on a routine basis or to react to fluctuations in traffic due to incidents or other events. Traffic monitoring and data collection are essential to uniform measurement of overall system performance and provide valuable input to the resource allocation process. This further indicates an area where agencies must focus their attention to improve performance.

The City of Plano, Texas used the opportunity of replacing their signal systems to incorporate real-time data collection and archiving in order to allow engineers to improve the system and target their maintenance needs. These increased data collection capabilities allowed the signals division to place a heavy emphasis on customer service, moving all modes (both motorized and non-motorized) through the system effectively and efficiently.
