Recently, South Korea announced a report show that the annular intersection of serious expansion and introduced in 2010 has shown an effective role in preventing traffic accidents and improving traffic flows.
The South Korean Land Transportation Provincial and Public Administration and Security Department announced the main achievements of the annular intersections that have been installed in the past 10 years in the past 10 years. The ring road has no traffic signal light and signal waiting time, thereby reducing passing time of the crossroads, and induces natural traffic flow, thereby reducing the incidence.
The Korean government has developed and installed the annular design guidelines in 2010. As of the end of 2020, there were a total of 1564 circles.
By analyzing traffic accidents before and after the ringing intersection, the number of traffic accidents was reduced from 817 to 615, a reduction of 24.7%, and the number of casualties was reduced from 921, which was reduced by 33.1%. . In particular, the number of deaths from 17 will be reduced to 4 people, a reduction of 76%, and the number of serious injuries is reduced from 431 to 257, which is reduced by 40%, which indicates that the incidence of serious accidents has declined significantly.
According to the data released by the Korean government, it is also very good to reduce the wait time. The average driving time shorten from 25.2 seconds before installation to 19.9 seconds after installation, shortened 5.3 seconds (about 21%), indicating that it is effective for moving the vehicle smoothly.
In fact, there is an advantage of each of the annular paths and the crossroads, and each has its own use scenario. Generally, the annular road is suitable for the road to the road, and the traffic is relatively large. If it is a general city road, then the efficiency of the ring road is relatively low. Often, we see that the ring road is easy to communicate.Incident, this is mainly due to the large traffic, and the motor vehicle, non-motor vehicle uses, thereby causing high probability of traffic accidents. However, if the motor vehicle is allowed on the ring road, then not only the efficiency of travel will increase, but also reduce the probability of traffic accidents.
At present, the most common crossroads in the city is more suitable for areas where roads are relatively narrow, and cross-crossing through traffic signals, which can effectively achieve certain order, and motor vehicles and non-machine The motor train can also be diverted. But in the final analysis, no matter which way, you need to pay attention to traffic safety, because there is no safest way, only people who don’t defend the rules.
