The Mobile WYSP uses devices called speed display signs or driver feedback signs which contain a radar device and an LED display. These signs are installed against an existing hydro pole or streetlight. The radar measures the speeds of oncoming vehicles and the LED sign displays their speeds to the passing motorists, thereby reminding them to check their speeds and to obey speed limits. The City’s portable units are rotated throughout each ward on a monthly basis throughout the year. This dataset contains a summary of observed speeds for each sign installation and the operational parameters of the sign. See Mobile Watch Your Speed Program – Detailed Speed Counts for hourly speed counts.
