Through the optimization of transportation organizations, transportation facilities and signal lights, the transformation of Checheng North Road, Dongfeng Avenue

The Yangtze River Daily Da Wuhan client July 26th. The North Road of Checheng Road, Dongfeng Avenue, is currently the most important blocking point on Dongfeng Avenue. It is not far from the Triangle Lake. The period of time is about 14,000 vehicles, and the traffic ranking is the first in the open area. Even if it is flat period, the traffic is not small, reaching 4,000 vehicles per hour, so traffic congestion is more prominent.

The lane division is unreasonable, the pedestrian crossing the street is imperfect and the congestion is exacerbated

Song Jian, the captain of the traffic brigade of the Wuhan Economic Development Zone, introduced that the Nanfeng Avenue's Checheng North Road intersection was imported as the ground and lower ramp from Dongfeng Avenue. There are 7 lanes (the lane is divided into 1, 2 lanes left, 3 to 5 lanes go straight, and straight lanes are straight. 6 lanes turn left, 7 lanes straight+right). There is a problem of congestion during the peak period of the ground layer and the lower ramp traffic.

Dongfeng Avenue's Checheng North Road intersection is imported from 5 lanes (the lane is divided into two left, 2 straight, and 1 right turn). Therefore, the left transfer is easy to queue, and it is easy to have interweaving conflicts with the discharge segment and the direct train flow, which seriously affects the traffic efficiency. Slowly traffic in the southwest corner is small, while pedestrians and non -motorized vehicles have a large flow. It does not match the capacity of the existing waiting area, which affects the normal traffic of the right -to -right vehicle in the west imported. In addition, the north -south side pedestrian crossing the street is about 42 meters long and the distance across the street is long. Pedestrians in the north and south side of the north and south, those who enter the intersection in the later stage of the signal phase, can not be fully passed through the intersection. There are not only hidden safety hazards, but also reduced the efficiency of north -south vehicles.

Cover the block through the optimization of traffic organizations, transportation facilities and signal lights

Lin Xiang, the captain of the order squadron, said that according to the current situation and traffic survey of the intersection, it is prepared to adjust the optimization of traffic organizations, transportation facilities and signal lights.

First of all, a set of signal lights will be set up at the undergoing ramp and the ground floor of the intersection. The peak hours will be controlled by the ramp vehicles and ground floor vehicles to solve the problem of interwoven conflict between the lower ramp vehicles and the ground floor vehicles. Second, adjust the lane. The original 1 and 2 lanes imported from the intersection are left -turn lanes, 3, 4, and 5 lanes are straight trains, 6 lanes are left -turn lanes, and 7 lanes are straight and right lanes. , 5, 6 lanes straight. The proportion of the original 7 lanes found that straight vehicles and right -to -right vehicles were found to be 1: 7. In order to improve the traffic efficiency of the right -to -right vehicle, the 7th lane is directly changed to the right -to -right -specific track. At the same time, the original 7 -lane straight area is expanded into a non -motorized vehicle and pedestrian waiting area to reduce the distance and time crossing the street.

In addition, the lane plot ratio will be increased. The east imported left traffic in the direction of the sports center is relatively large. We are going to extend the gradient section of the left lane to extend 100 meters backwards to increase the plot ratio of the lane, and at the same time alleviate the problem of interweaving the left turn and straight vehicles in the middle of the road.

The traffic management department will also standardize pedestrian waiting areas and right -to -right -to -vehicle lanes. In the West imported through the color marked line and reflector, it is clear that the non -motorized vehicle and pedestrian waiting areas are clear, and the right -to -right -transfer lane diversion line is applied to reduce the influence and interweaving of non -motorized vehicles and pedestrians when waiting for the right to turn on the right. At the same time, change the intersection to the full screen light group to the arrow head light, and implement the conflict between the left and straight to solve the conflict between the left -turn vehicle and the pedestrian. And set up a secondary cross -street safety zone. The road of Dongfeng is wide, and the pedestrian crossing the street is too long. It uses the current bridge pier to apply pedestrian to cross the street waiting area to solve the problem that specific pedestrians cannot cross the street at one time.
