Original: People's Network (http://www.people.com.cn/gb/qiche/29883/2359089.html) The original text of the Xizhimen traffic police: (173857.aspx) Beginning in 1994, Beijing Municipal Engineering Design Research Institute used For 4 years, the design of the new intersection is made. In 1999, investing 2 billion new Xizhimen overpass has been pulled off ...
Just two years, here is one of the most traffic traffic in Beijing.
Zihuqiao is a blocked point in Beijing before the transformation, and the municipal government is determined: change. After the transformation, Zizhuqia has built two ramps in the middle of the road. It is said that this is to draw on advanced experience in foreign countries. The vehicle can directly turn left directly from the fast lane to avoid cross. It is, this is only one, many drivers have long been used to walking out the bridge to the right way, suddenly there is a novel road, the driver will not go, do not dare to leave ... The result can be thought of , Or blocked.
Tianning Temple Bridge is located in the Tianning Temple area of West Second Ring Road. The Second Ring Road and Lianhu East Road, built in 1991, is a three-layer alfalfa shaped orientation composed of 17 across the river. Type interworking. At the beginning of the design, this is one of the beautiful open bridges in Beijing. It is now 365 days a year, more than 300 days, the bridge is full of dense label vehicles, from Guanganmen through Tianning Temple to Fuxingmen, daylight Worm, night like dragon ...
In the past two years, Beijing's traffic jams and Beijing's famous monuments have spread throughout the motherland and got out of the country, and they went to the world. Take the second ring road as an example: Fuxingmen Bridge, Jianmen Bridge, Dongzhimen Bridge, Xizhimen Bridge, has become the four big plug points in Beijing. The Xizhimen is also very concerned by the public with its geographical location. Every morning, I became the ocean of the car, and the vehicles in all directions were gathered here, and then through the main road, the divide of the secondary road, flowed to the eight side. Here is a recognized transportation hub, but does not play the role of the transportation hub.
Congestion of traffic hub
Xizhimen daily blocked. What is the reason? It's a large traffic, it is a pedestrian to wear a motorway, is a motorized lane in the non-motor vehicle? Is the road design not reasonable enough, or the traffic police commanded? Let's listen to the reflection of the parties:
Driver: The road design is unreasonable.
"Investing in two hundred million, repairing this, I really don't know what they think, how to design." Master Zhao is a taxi driver, pulling guests almost every day. Every time you pass through your headache. "There is also two miles away from the West. I don't know if the designer will not go here."
Expert: The planning and design is unreasonable.
The planning and design of Xizhimen is mainly the traffic capacity of the road and bridges, the import ability is high, the export is low, and the car is full. When designing, the matching of road bridges is critical data, and it can reach the road smooth car. The current fact is that vehicles that are greatly exceeded from design traffic gathers from the northwest direction of Beijing, and the road network structure is a major cause of traffic jams. This is very similar to the blood vessels of the human body, and a large number of capillaries under the aorta can protect nutrients can be delivered in place.
Citizen: Transportation facilities are unreasonable.
"The road sign is unclear is a main reason for traffic jam. I found that the road sign was late. If the brake is easy to make a traffic accident, it will definitely open it. There is no congestion to other roads in invisible."
The reporter is roughly statistically, only nearly 100 small traffic signs in the Xigmen Bridge area, and the ban, the left sign, and the driver's cloud is not known. Many drivers reflect despite many west straight, but it is easy to turn, some cars need to go to the road, some cars need to take auxiliary road, and some cars need to take turns, which makes people feel very confusing. Designer: The reporter learned the designer of the West Strain Bridge by looking for information. She design this bridge mainly is to solve the main lane traffic problem through the directional ramp. According to the model test, the mainstream direction and main flow of the traffic flow are analyzed. It is said that this approach is considered to be the most scientific settlement method, avoiding the contradiction between the circles of the old bridge in the old bridge, making the passage of the West Second Ring from the original 9,000 units to 12,000 vehicles. "Since the bridge is limited by the land area, others are considered to be the secondary direction must be bridge." It is true that the main car is not fast, and the secondary traffic is more blocked.
Representative proposal: a map of overpass
At the two sessions of Beijing, the Municipal People's Congress representative, the Ma Runjin, a professor of the Northern University of Technology, submitted a proposal to the General Assembly to the General Assembly. Other representatives and relevant departments have attracted attention.
Professor Ma:
The number of overpasss in Beijing is numerous, and the shapes are different. Although many all-in bridges have beautified the capital, they will let Beijing's drivers do not know what it is. The overpass design is very complicated, as if the heart and driver can't go, the driver who is not familiar with the road is, especially the foreign driver of the Beijing office, it is a very headache, often happened, not there. The phenomenon. The important reason for this phenomenon is that the symbol of the overpass and the driving instructions are not perfect, clear. Different vertical bridges turn left, right turn, straight, and turn around, the same loop light can have three or four kinds of ways.
If the overpass rebuild is removed, it is obviously unrealistic, it is impossible. The simplest, fastest way is that all drivers and road participants are familiar with the performance characteristics of the overcomers, and road managers have developed the most clear and clear indication. The shortcut to the human hand or the Internet is a good way to save money and save time. Now some maps are also marked with a overpass, but it is very unreliable, and I don't understand.
Professor Mass Professor:
1. A completely reliable Beijing overpass direction map, like a Beijing manual, one year, one year. You can also publish a driving route on the Internet for query, but you must be true and accurate.
2. To follow the structure of each overpass, draw a full range of straight, right turn, left turn, turn down, labeling the entrance and exit of each overpass, how to enter, how to come out.
3. The overpass indicator should have gradually informative, and a clear and eye-catching traffic sign should be established in a place for two or three hundred meters away. How to go left, how to go right away, how to go out and wait. The traffic sign on the overpass should be simple and clear.
