The initial push behind the posting of travel time information onto DMS was the result of driver complaints concerning the posting of safety and other static messages to the DMS. Reader stations are, on average, two-to-three miles apart, but not more than five miles apart. Data from these vehicle probes is collected at 232 supplemental reader stations and transmitted to the TranStar TMC for analysis. These travel times are based on data collected from the close to two million "EZ-Tag" Automatic Vehicle Identification (AVI) toll transponders currently circulating around the Houston metropolitan area. TranStar began posting travel times onto DMS in 1996 and currently posts travel times onto 81 DMS across more than 250 centerline miles of Houston area freeways.
