Optional Easy & Accurate Reporting

Accurate raw data collected by VCalm® S Radar Speed Signs can be used to construct limitless report formats and parameters for thorough data analysis. Traffic Data Acquisition System (TDAS) collects the fastest and slowest speed for each vehicle. Signs collect Peak, High, Low and Exit speeds, each with their own date, time and seconds.  With this information, users can determine whether vehicles are speeding up, slowing down or remaining the same as the pass through the detection zone.  If the detection zone is mapped, the zone location of the vehicle can also be determined.
