Taiyi Interchange implements the "main road fast separation parallel zipper to the upper and lower three -dimensional induction" traffic speed increases by 13%

The ramp remittance is large

The vehicle of the intersection is easy to grab the road

Recently, some citizens reported that the South Second Ring Road was slow to drive east to west, which seriously affected the traffic efficiency of the South Second Ring Road.

On June 17, the reporter learned that with the Xi'an Public Security Traffic Police completed a "minimally invasive" operation here, through the implementation of "the main road fast separation+parallel zipper, the up and down three -dimensional induction", the speed of traffic has increased here. 13%, realized "small transformation, big improvement".

"Fast separation of traffic" ensures that the second ring road main road is fast through

According to Xie Fei, deputy department head of the Planning Division of the Traffic Police Division of the Municipal Public Security Bureau, Taiyi Interchange is a traffic conversion point connecting the two expressway two fast roads in the South Second Ring Road and Xiyan Road. After the opening of the viaduct of the Xiyan Road, Taiyi conflicts did not expand simultaneously. The traffic quickly gathered at the entrance of the South Second Ring Ring. The phenomenon has exacerbated congestion. During the morning and evening peak hours, the Paidi of the South Second Ring Road from the east to the west has become a traffic jam that restricts the regional traffic.

"In order to alleviate the conflict between the trail of the Taiyi Diaoyang Road ramp and the second ring road main road, we redesigned the lane of the original 'fast and slow separation", which improved the speed of Taiyi from the main road of the second ring road in the east to west. "Xie Fei said.

During the transformation, the traffic police planned the fast -separation of the diversion line here, set the two lanes in the inner side of the South Second Ring Road to the fast lane, set the outermost lane to be a slow lane, and set the fast slow lane to the gap into reasonably. The road will be extended by 50 meters to the segmented diversion line, minimizing the congestion and accidents caused by irregular changes caused by the vehicle near the ramp entrance, and ensure that the fast lane is fast.

At the intersection of the two -ring fast lane at the gate of the Ninth Ring Road and the Ninth Hospital, the ground text is applied to guide the long -distance and go to the direction of the Taiyi Route. The sudden change of the road caused the second ring road main road to decline.

The "parallel zipper pass" ramp is significantly improved

"The fast separation of Taiyi Laijiao West Yan Road ramp is bound to suppress the circulation capacity of the west extension road. In order to improve the traffic performance of this section, we have implemented the" parallel zipper "traffic organization here." Xie Fei said.

According to reports, the "parallel zipper pass" is the road section of the "zipper pass". According to the problem of uneven traffic on different directions of the road intersection, there is an uneven traffic on the right side of the original zipper. On the basis of the direction with a large traffic flow, multiple cars are connected together, that is, there are two cars on the right and a car on the left, thereby improving the traffic capacity of the large road.

In order to achieve the "parallel zipper pass", Xi'an Public Security Traffic Police set up a multi -level traffic signs labeling line for guidance at the combination of Taiyi traffic ramps. Draw the diversion marking line at the ramp, and clearly converge into the car's popular trajectory. At the same time, the text of the "alternate driving" and the "1, 2, 3, and 4" digital marks on the ground, guide the main line of slow lane through a car, and the ramp will drive the two cars into the main line slow lanes in order. Drive alternately.

In the South Second Ring Road's main line and ramp, both parallel zipper traffic guidance signs are added, prompting drivers to guide the traffic according to the ground marking line; add the "combined flow of traffic, prohibit changing lanes" sign, separate the "fast and slow traffic flow", and prohibit the remittance of the vehicle pressure line. Enter the fast lane to ensure that the second ring road's fast lane is smooth.

"S three -dimensional induction" dot and wire surface combination to speed up and speed up

In order to ensure the implementation of the "parallel zipper pass" traffic organization, the Xi'an Public Security Traffic Police also carried out simultaneous transformation of other easily blocked points in the South Second Ring Road.

In terms of improving the sign of the road under the bridge, the traffic police added an 8 -faced street sign to ensure that the vehicles under the bridge can understand and go smoothly. By planning the virtual and real line, only the vehicle driving in the fast lane at the entrance of the ramp is allowed to enter the slow lane, and the vehicles driving slow lanes are not allowed to enter the fast lane. The influence of circulation.

With this series of renovation measures landing, after the monitoring and analysis of the Xi'an traffic police Internet+big data road conditions platform, the "parallel zipper pass" traffic organization was implemented, and the frequency of congestion at Taiyi Dianxin Road Ringcousta was reduced by 18%. With the change of the traffic point, the Pacific Bye of the South Second Ring Road was significantly reduced by the main road congestion index from the east to west, and the driving speed increased by 13%. The main speed of the main road was significantly improved. The effect of the decline of the transformation has completed the travel goal of "point and line, from line to face".

Xi'an Public Security Traffic Police reminds that when the South Second Ring Road is over, please pay attention to observing the logo line set by the traffic police department. Do not grab the road, do not cross the line, alternate the "zipper" traffic, and civilized driving reduces human blockage.
