PennDOT currently has 38 active IRD WIM systems that are covered under this agreement. Nine of these include overview camera systems. Data collection and planning site locations are made up of in-road instrumentation and IRD iSINC WIM electronics and software.
Historical data collected from these sites are used to develop daily and seasonal factors, as well as to identify changes in traffic patterns. Real time data is used to enhance safety and assist the State Police with enforcement activities, resulting in reduced roadway damage and increased preservation of pavement and infrastructure.
