Speed Check Sign Aggregated Data

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.

Bin 1 can also be referred to a LO BIN and Bin 10 can also be referred to as HIGH BIN. Things to note: Speed Check Sign devices are not to be used as or confused with traffic counters, as they are not. Speed Check Sign devices have a minimum detectable speed of approximately 6 km/hr.

Speed Check Sign devices have a maximum (theoretical) detectable speed of approximately 225 km/hr. Speed Check Sign devices are programmable with different parameters that can also follow a timed schedule.
