the face of increasingly severe traffic congestion, traffic majors Li Xu two years to design space. The design lead to hot friends. Some users that the program conducive to resolving the Beijing traffic jam. Li Xu also said that its program for Beijing. But some experts pointed out that if adopted, would only exacerbate congestion.
WASHINGTON Recently, the blocking
User Amy0311 that the existing overpass, such as the North Pacific Zhuang, the main line straight without traffic lights, turn the vehicle to wait for lights.
the design one, causing users to Beijing prick the existing overpass. User Ttyin said North Star overpass lack of convergence from the north east of the bridge approach to the North Fourth Ring East. North Third Ring Road and North Fourth Ring Wanquan bridge, the bridge from the south west of the lack of connection Wanquanhe North Fourth Ring Road westbound bridge approach, resulting in the North Fourth Ring Road westbound vehicle had to turn around under the overpass to the Summer Palace Road bypass. There are user pointed out, many roads converge at the overpass with the five rings, or rings can not be driven out, or not into the rings. Netizens said that the problem caused congestion around the overpass.
User spoon that Shuangjing bridge design problem, bus stations, subway stations, shopping centers concentrated, loop export vehicles and bicycles, pedestrians intertwined, very confusing, and that Well rule blocking the bridge.

Beijing lane flat for the program
the applicability of the program for Beijing, the designer Li Xu is optimistic. He said the program especially for Beijing, because Beijing is more than an intersection, and the roads are wide, well-organized.
Li Xu said that in the Chang'an Avenue,
mbt discount shoes, turn left is a big problem, Chang'an Street congestion has become more critical. Li Xu's program, but also questioned by some members of the public. Lee read the public in the design of the program that is simply beyond the outward expansion of the main road turn left into the internal ring. This design allows the two main road suddenly reduced lanes. This needs to slow the junction will cause major congestion.
present, Li Xu has submitted information to the
expert
Beijing will aggravate the congestion of the design
day before yesterday, city housing construction, deputy director of traffic engineering, Marin said, students design commendable. But the If adopted, Beijing will be more congestion.
Marin believes that the lack of engineering and technical basis of the program, and if some of the overpass in strict accordance with design standards, such as slope, turn ramp and other factors, these are taken into account, the implementation of specific size, will no longer be
Marin, said the design did not take into account the traffic problems, according to this program, vehicles will inevitably decline in the rate of turn, for a huge city like Beijing traffic flow, speed, once reduced, it will cause more severe congestion . Steep and that the program encountered Yu Xuetian, driving more difficult. In addition, the program exists in the line of sight on the blind spot, four on the interchange,
fer a lisser ghd, the next left turn lanes and the smaller the distance between the U-turn lane, turning radius, less headroom under the bridge, the overall index lower, likely to cause traffic sight interference, easily lead to accidents.

father lost business, inspire design traffic jam
22-year-old guy from Henan Li Xu two years to design He believes that his proposal is superior to the traditional interchange can alleviate Beijing traffic jams. The day before yesterday, our reporter Li Xu dialogue.
Beijing News: Design
Li Xu: his father to Beijing to do business in 2007, lost a big traffic jam due to a single business. Beijing has started a traffic jam when the father is not good that Beijing many overpass design, such as Xizhimen overpass too complex. I designed Father interested in drawing some of his work is done.
Beijing News:
Li Xu: did not expect to cause such a big concern, indicating that severe traffic congestion, there are inadequacies in the existing overpass. Internet users have personal experience, only to arouse their attention.
Beijing News: Many users criticized your
Li Xu: It really is a defect, but also consider this issue, perhaps through the erection of bridge or underpass solution.
Beijing News: User mention a lot about the how to read?
Li Xu: design in the use of time is not static, but according to the actual situation, including traffic and other local conditions. Expert advice to help me a lot, such as blind sight, people and vehicles intertwined issues are before the ill-considered place.
designers Li Xu believes that Some people suggested the use of the program to
Li Xu said that although the characteristics of Beijing for the road with his program, but to a specific location for use immediately to make sure he could not answer. Need to research the local traffic, road characteristics and surrounding environment. Well-site visits to the bridge, in the Shuangjing Qiaodongbeijiao, Guangdong and Guangxi Road, turn left over from the vehicle just a bridge, in front of that many bus stops, including 28 Road, 37 Road, 57 Road, nearly 20 bus line this station. When the bus stops away from the bridge too close, the crowd swarmed the car and other car and bike paths cyclists mix, resulting in a blocking point. The northwest corner of the bridge, there is a large shopping center, some vehicles parked on the roadside at random, take bike lanes, cyclists pushed on the motor vehicle lanes, exacerbating congestion.
in Shuangjing west, the direction of the south from the World Trade Bridge, If you go to Guangdong and Guangxi Road, without the need to bridge the time Shuangjing leave the main road, but leave the main road and side road traffic vehicles, bicycles, pedestrians intertwined, and the edge is the bus station, subway station, a huge mix of people and traffic, but also to form a blocking point. The owner of the nearby newsstand,
discount gucci bags, said the peak morning and evening, often packed, almost daily cut rub, 200 meters and even driving the road to wait half an hour.
In addition, under the bridge from the east to the Guangqu Shuangjing West Da Wang Road intersection, this is only 3 km of the road, were set four lights, resulting in slow speed, traffic queue.
people very fact that the design of Li Xu, if used here, from Guangdong and Guangxi Road to international trade, no matter which direction the traffic lights, turn left will be very convenient, multiple entrances and exits through the interchange will be traffic on the dispersion, the speed will not decrease too much, jamming point will disappear.
【Comments】
governance must address the people and cars blocking Mixed
overpass more than a decade of civil designer Zhengxue Xin Li Xu in the program after reading that The design of traffic-cutting issues are not well resolved. Therefore, the bridge is not suitable for such traffic Shuangjing great place.
Zheng Xuexin that the traditional design of the overpass traffic weaving, and the biggest problem is that hybrid vehicles. Shuangjing blocking point is that the bridge formation. Mixed traffic where road capacity discount. In addition, motor vehicles and bicycles to go in parallel lanes, hybrid vehicles when turning, there will be traffic intertwined, the result is confusion. Li Xu's design does not address the problem of the measure.

reader suggestions overpass rule blocking
since 1974 built the first bridge overpass Fuxingmen, Beijing has now nearly 200 overpass ,
louis vuitton belts for men, it is difficult to alleviate the increasingly serious traffic congestion. Many people think that some of the overpass in form than practical, more complex design, so access is limited. Some people might think, but the formation of a blocking point overpass.
