MOVE_UK is making thousands of traffic speed sign detections a month as our fleet of five Jaguar Land Rover Discovery Sports are driven in the Royal Borough of Greenwich by Council staff.
So far, 43803 detections have been made between 2 January 2017 and 12 January 2018. That is an average of 3650 detections per month. 30 mph traffic signs are being detected on average 1590 times a month, which is nearly twice as much as 20 mph traffic signs that have, on average, the second highest detection of 850 a month.
The onboard camera in our fleet of vehicles detects speed traffic signs, processes them and uploads the data to our cloud server. Using this data and the analytical tools we have created, we are able to visualise on an online map the different speed limits of roads in and around Greenwich and where exactly the corresponding signs are being detected.
In the future this system has the potential to produce dynamic maps based on the data gathered from connected vehicles. For example, by using current and historical data of a particular position in Greenwich we could create a dynamic speed limit map that would auto update whenever a sign changes, is removed or installed.
