Traffic signal timing of science is not trivial

Zhengzhou city trunk road in the Central Plains Road and Hing Wah Street intersection, about 60 meters wide walkways to 20 seconds of green time, healthy young people go a half lit up the red light, aged body weak through here is more difficult, known to the people of the signal lamp, tend not to wait for the green light began to cross the road. This situation has been confirmed by the reporter. In this regard, the traffic police department said that this intersection signal timing is indeed a problem, but it should not be had set the intention, they will be immediately sent to view, to make adjustments.

In the city on the road, not only cars, electric cars, tricycles, bicycles and pedestrians. In order to improve the traffic efficiency and avoid the occurrence of accidents, not only to provision prevails, and in each intersection signal to pass time of science fair division. The major premise is, of course, enjoy equality of rights of way, but also because of the provisions of the law or advocate some social ethics and make appropriate tilt. Such as the occupation of the pavement more car must pay the maintenance fee; for example, to set a dedicated channel for the vulnerable disabled population; for instance, for the sake of environmental protection, preventing jams and encourage drivers changed by other means of transport, signal lamp will be set in the appropriate to the non motor vehicle and pedestrian more time.

To follow this principle, had installed here the traffic signal lamp, traffic signal lamp manufacturers traffic scientific research departments should be prior statistical different flow direction and passage way. On the basis of division of the time. When the lights began to run, but also for the time field observation, once found a direction or a pass walkers at a disadvantage or very "dipping", immediately corrected, then observed until it reaches the best results so far. But do this step is not enough, because with the surrounding residential population changes or other factors influence, this intersection in all directions of traffic also changes, also need traffic management more observation, analysis, timely on the signal timing adjustments are made. From this perspective, the intersection of the Central Plains Road and Hing Wah Street pedestrians difficult problem, is likely to appear in the late tracking management.

The traffic signal timing problem is not a small thing. Especially in the busy downtown, signal lamp if timing is not reasonable, but to pass walkers rights do not respect and reduce the traffic efficiency, increase congestion, fuel waste, air pollution, delay time, will lead to a pedestrian red light running, formation of traffic accidents, it is necessary to attach great importance to.

In fact, the traffic signal timing is not science, this phenomenon is not rare in Zhengzhou, as in the Zheng Dong area, traffic flow is small but the red and green light signal conversion frequency is too low, there is a lot of intersection. I hope the relevant departments to do a unified examination found unreasonable to be corrected as soon as possible. After all, adjust the signal light is not much big, just little things.
