Get Behind the Wheel
Try your hand driving on our specially customized Scalextric track, it has been fitted with traffic control! There are two traffic light controlled junctions on the track with different control mechanisms. Can you work out the difference?
The Science
Modern traffic light controlled junctions don't just work on a timer system. They use a large number of sophisticated sensors to detect where the vehicles are and optimise their decisions. Some of the sensor technologies employed are:
The Future
In the future vehicle's on-board computers will carry WiFi communications technology allowing them to communicate with other vehicles and with infrastructure. Vehicles will be able to use their own on-board sensors (e.g. GPS) to measure their position and speed and broadcast this over WiFi. This will give the invisible referee even more data with which to judge the state of the road and make smart control decisions.
