Speed Check Sign - DFS280

These units collect data as traffic approaches them and in some cases may display a message or a speed that is being detected. Also, these units are radar based and can only track one vehicle at a time (strongest signal).

Due to the number of Speed Check Sign installations combined with the volume of data collected, each Speed Check Sign has its own dataset. Details of how the data is collected by the Speed Check Sign are as follows: - Data is accumulated and reported in 15 minute intervals - Vehicle speeds are captured/reported in speed intervals (bins) - Speed range/interval for the bins are determined by parameters/settings set for the Speed Check Sign (Minimum/Maximum Speed Detection Setting) - Two speed values are recorded for every vehicle - a Highest Speed Detected and a Slowest Speed Detected (explaining why there are two vehicle counts) - The bins go from Bin 1 to Bin 10.
