Overview of Location

Geographical location of the intersection

The intersection of the two main roads of avant -garde West Road and Japan New Middle Road is located in Xishan District. The surrounding plots are mainly residential, education, and commercial land. The avant -garde West Road is the main road of traffic in the north and south, north to the south road of the second ring road, and the South -to -Dianchi Road in the south. It is the main road of east and west traffic, connecting Yulong Road in the east, and Dianchi Road in the west.

Problems and analysis

Intersection traffic operation

From the perspective of the traffic operation feature index of the morning and evening roads of the Avantra West Road and the Niger -Xinzhong Road, the service levels of North imports, South imports, east imports and west imports are all in E -Class. The longest length is 123m, and the most delay index in South import (avant -garde West Road) is 66.42s. In the evening of the evening, the most queuing length of the East East Import (Ri Xin Middle Road) reached 168m and the delay index was the highest, reaching 69.99s.

Existence

(1) During the peak period, traffic flow is large, and local congestion is prone to occur.

The intersection is the intersection of the two main roads of avant -garde West Road and Japan Xinzhong Road. The roads on Qianwei West Road in the south mouth are narrow. The roads on the north side are relatively wide, the intersection is irregular, the vehicle traffic rate is not high, and the traffic flow during peak hours is large.

(2) The traffic flow of the north -south peak hours of the intersection is large, but the signal light is not enough to meet the traffic needs of vehicles during the peak period.

The current situation of the cross -section of the cross -peak period of the import period of imports is low, and the green letter given by the signal matching scheme is relatively high. It does not match the actual traffic needs, resulting in a low utilization rate of green lights, which affects other flowing time. operation efficiency.

(3) The intersection of the Qianwang intersection and the avant -garde camp intersection adjacent to the avant -garde West Road is close to the overflow congestion caused by insufficient signal light coordination.

Optimization measure

Adhere to the principle of "one point and one strategy" governance, and adopt a combination measure of "traffic organization optimization+signal adjustment+traffic management enhancement" to control points.

(1) Organization -precisely fitting, maximizing space utilization

(2) Signal deployment -accurate adaptation of traffic, green light time is not wasted

(3) Traffic management -the intersection is controlled and controlled, the order order is orderly

Transportation organization optimization:

North imports increase left and straight to the area;

North -South imports add non -motorized vehicle to available areas;

Add the corresponding signal light to the screen.

Increase

Signal matching time optimization

The survey found that during the evening peak, the vehicles turned left at the west side of the intersection rarely or even the phenomenon of air release, and there were more vehicles left on the west intersection. Consider optimizing the signal time of the late peak period at the intersection to increase the phase of the east import straight left overlap.

Avantomy West Road-Japan Xinzhong Road improves the peak signal with the peak signal in the evening (C = 165s)

Reinforcement of traffic management

Strengthen the coordination with the anti -overflow of the front and downstream intersection of the avant -garde West Road and the Qianwei Camp Road light control.

Strengthen anti -overflow control, and arrange personnel to overflow control at the intersection of the Yizhong intersection and the avant -garde camp.

Improve effect

Speaking accurate data, the delays index decreased

The entire intersection and cross -port line length and delay index are declining. Among them, the north mouth of the newly increased north mouth decreases the most obvious, the queue length decreases by 27%, the delay index decreases by 25%, and the effect of blocking point governance effects Significantly.

The intersection service level has increased, and the list of blocking points has been exited in July

Compared with the optimization adjustment of the intersection, the service level of the Activities West Road-Japan Xinzhong Road has been increased from E to D. The service level has been improved by one level. quit.
