智能交通灯用以缓解拥堵压力
Groundbreaking new traffic lights fitted with artificial intelligence could create safer roads and bring an end to rush hour gridlock.
开创性的人工智能交通灯将为行人创造更为安全的道路环境，使路况高峰期的交通拥堵不再发生。
'Smart' traffic lights will monitor speed and congestion, prioritise cyclists, buses and ambulances with green lights and use heatmaps to analyse how pedestrians and motorists are using the roads.
Milton Keynes is set to be the first city to trial the £3 million project from September, with 2,500 sensors monitoring all major junction points and car parking spaces.
The monitors recognise different vehicles and individual road users and will be able to regulate traffic in real-time.
At present, traffic lights are sequenced but not reactive to the vehicles around them and traffic monitoring is still done manually.
Cameras will also allow traffic lights to prioritise cyclists, buses or ambulances with green lights.
Vehicle dashboards that communicate with traffic lights could also flag the presence of cyclists to lorry drivers.
The technology could also enable traffic lights to communicate with driverless cars around the corner and inform them if pedestrians are crossing the road.
