The role of integrated road traffic lights in urban planning

Integrated road traffic signal lights play an important role in urban transportation planning. It not only ensures the safety of pedestrians, but also improves traffic mobility and improves urban traffic efficiency. The following will elaborate on its role in urban transportation planning from several aspects.

• First of all, integrated traffic signal lights can ensure the safety of pedestrians. Pedestrians and motor vehicles drive together on urban roads, and pedestrians often face hidden dangers when crossing the road. Integrated road traffic lights use traffic signals to clarify the time for pedestrians to cross the road and the time for motor vehicles to pass, reducing conflicts between pedestrians and motor vehicles and improving the stability of pedestrians crossing the road.
• Secondly, integrated traffic signal lights can improve traffic mobility. In traditional crosswalks, pedestrians often have to wait for a long time to cross the road, causing traffic congestion. Integrated traffic lights can adjust the time of the signal lights according to the actual situation, reasonably allocate the right of way for motor vehicles and pedestrians, reduce traffic congestion and improve traffic mobility.

• Thirdly, integrated signal lights can improve urban traffic efficiency. Traditional crosswalk signals require pedestrians to press a button to trigger changes in the signal lights, while integrated traffic lights can automatically detect the arrival of pedestrians through sensors and adjust the changes in the signal lights in a timely manner. It not only reduces the waiting time of pedestrians, but also improves the traffic efficiency of motor vehicles, thus improving the overall efficiency of urban transportation.
• In addition, integrated traffic signal lights can also reduce the incidence of traffic accidents. Traffic accidents on the road are often caused by conflicts between pedestrians and motor vehicles, and integrated road traffic signal lights reduce the probability of accidents by clarifying the passage time of pedestrians and motor vehicles. Especially at some busy intersections, the installation of integrated road traffic signal lights can better organize the passage of pedestrians and motor vehicles and improve traffic smoothness.

Later, integrated road traffic signal lights can also improve the traffic awareness and civilized quality of urban residents. In urban traffic planning, the setting of integrated road traffic lights is not only a traffic management measure, but also a traffic education method.
