CITY buses may soon be able to change the traffic lights to get through crossroads quicker, in a measure being considered by the city's transport officials.
Local traffic authorities are studying a system that would send a signal from the bus to traffic lights ahead, making the green light last longer or shortening the red light time.
Yang Changhai, deputy chief economic engineer with the city's transport and port bureau, said the "bus privilege" system would increase vehicle speed.
At present the traffic lights change about every one to three minutes.
Using the new equipment, buses can send signals to the traffic lights when they are still 100 meters from the intersection. The red light would switch to green in time for the bus to avoid having to stop.
The city will test the system on some bus lanes downtown after the end of the World Expo.
Meanwhile, the city's first Bus Rapid Transit system is unlikely to be built as planned, officials said yesterday.
The transit system can carry hundreds of passengers in one vehicle at 20 to 30 kilometers per hour.
The first BRT was due to link Shanghai South Railway Station to Shanghai West Station. BRT lanes would be off-limits to other vehicles and pedestrians, but this was difficult to be guaranteed on downtown streets, experts said.
Instead, BRT is expected to make its debut in suburban Shanghai.
