Cheng Dehong, a deputy to the National People's Congress, began to deal with the "road" since 1981. In his view, the first thing that traffic has to solve is the travel of ordinary people. This is the most fundamental problem. As the chief engineer of the Engineering Quality and Safety Supervision Bureau of the Chongqing Municipal Transportation Commission, Cheng Dehong recently issued a “prescription” for urban traffic congestion when interviewed by the “Legal Daily” reporter. He said that to control urban traffic congestion, it is necessary to constantly develop intelligent transportation and improve the level of urban traffic management from the perspective of overall planning.
In Cheng Dehong's view, the current motor vehicle restriction policy in Beijing and other cities has certain positive significance, but the effect is not necessarily outstanding. "The implementation of motor vehicle restrictions, even the single and double number limit, there may be a situation in which a family buys two cars, but it does not achieve the purpose of limiting the growth of motor vehicle ownership. Although the number of vehicles on the road has decreased, The overall emissions of vehicles will increase. "Cheng Dehong believes that it is necessary to vigorously develop public transportation. For example, it is necessary to facilitate the transfer of citizens as much as possible so that people can get on public transportation when they go out, especially to solve the last one. Km" problem. For example, the implementation of peak shifts to work, these can play a positive role.
In response to the increasingly serious traffic congestion problems in the whole country, especially in large and medium-sized cities, and the resulting air pollution problems, Cheng Dehong has issued several “prescriptions”.
Cheng Dehong’s first “prescription” to ease urban traffic congestion is to manage the “people” on the road. In other words, we must find ways to improve the quality of the "people" on the road, which not only to improve the safety awareness of passers-by, but also to improve the driver's driving level.
"Now, there are too many novice drivers on the road, many drivers are slow to start, and even some novice drivers are almost finished with a green light to start the car. In the cities with more mountain roads in Chongqing, some drivers will start at the start. Rolling back, this situation has occurred much more, naturally affecting the smooth flow of traffic." Therefore, Cheng Dehong stressed that in the test driver's license should be targeted training, so that the driver who really has the road level to pass.
The second "prescription" is to vigorously develop the urban intelligent transportation system. Especially for a very large city like Beijing, the development of intelligent transportation will play a very good role in alleviating urban traffic congestion.
In Cheng Dehong's view, the German urban transportation system is very worth learning.
“There is a saying in Germany that it can run an entire German at an average speed of no less than 160 kilometers per hour. The reason for this effect is that there are many reasons. For example, the speed of Germany is not limited, the performance of the car. Good, the driver's technology is relatively good, the supervision department's responsibilities are in place, and the intelligent facilities are complete. These are indispensable factors. Especially the wide application of intelligent transportation facilities has played a vital role." Cheng Dehong specifically, for example, In the case of multiple red lights set on a road, once the first one is turned on, the red light will be released in turn, so that the vehicle can even pass through the road at an altitude of 80 kilometers per hour, greatly improving the road. Traffic volume. These are all worthy of our country's reference. For example, in China, only the timer in the traffic signal is simply time controlled. If you realize intelligent transportation, you only need to install a sensor on the signal light. Through software and program control, you can automatically adjust the length of time according to the traffic volume of the site, achieve the effect of fast traffic, and realize the traffic capacity under the premise of ensuring safety. maximize.
The third "prescription" issued by Cheng Dehong is that the supporting transportation facilities of the city should be more humanized, especially the flyovers and underground passages, which should be reasonably set up to realize the diversion of people and vehicles, and the safety will be guaranteed.
Cheng Dehong stressed that urban transportation construction must coordinate various departments. It is necessary to establish an effective mechanism, such as holding a joint meeting, or setting up a large functional department such as the Comprehensive Construction and Transportation Commission, and at any time, according to the needs and actual conditions of the people, the construction of transportation facilities should be carried out to solve the problem of traffic congestion in time.
The fourth "prescription" issued by Cheng Dehong is that it is necessary to improve the level of urban traffic management, truly let the car run and improve the capacity. "Now the traffic lights in some places have not played a good role, but they have also played a bad role. Five or six traffic lights are set in one kilometer, which gives inconvenience to the line, so many traffic lights are installed, and the security problem has not been solved. The efficiency is reduced. Therefore, the management design of road traffic must be scientific and reasonable." Cheng Dehong said.
According to statistics, vehicle and ship emissions are one of the biggest causes of air pollution. Traffic congestion is an important reason for the increase in emissions from vehicles and ships. The road is not smooth, the vehicle can not be turned off on the road, causing the vehicle to wear out, which consumes oil and increases the amount of emissions, which in turn causes atmospheric pollution and affects people's lives. On the other hand, vigorously promoting new energy vehicles, electric vehicles, etc., although it can alleviate some of the pollution on the emissions, but it will also cause pollution of used batteries.
"We can't cause more insecurity for a safety." For this vicious circle, Cheng Dehong believes that blindly restricting urban roads is a cautious act. In some cities, the speed of road design is 60 kilometers per hour. However, in the vicinity of kindergartens and schools, the relevant administrative departments are artificially set to 40 kilometers for safety reasons. In fact, these areas can be solved by building flyovers or underground passages. The safety issue does not give students the opportunity to appear on the road. The cost of repairing a flyover is about 1 million yuan, which is a simple and easy way to solve the problem of people and vehicles.
