The Traffic Speed Map was launched on Transport Department's homepage in 2010, and was extensively updated in 2021 to provide the estimated traffic speed of all strategic routes and some major roads. Apart from deduced traffic speed, the Traffic Speed Map includes special traffic news, snapshot images collected from the Transport Department's surveillance cameras and traffic detectors, estimated journey times of Journey Time Indicators and images of the Speed Map Panels. The traffic speed data in the Traffic Speed Map are updated every 2 minutes.
