The north-south straight ramp of Baihedong Interchange is located in Liwan District, Guangzhou. The middle of the ramp is connected with the northwest ramp of Hedong Bridge, so there is a great traffic safety hazard when the traffic is intertwined. The ramp was originally designed as two lanes. Previously, in order to avoid accidents at the junction of two ramps, Guangzhou traffic police diverted the ramp from south to north into a lane about 100 meters. However, once the on-ramp traffic is saturated, there will often be traffic order problems such as vehicles competing for lanes and rushing in the reduced lanes of 1.
Recently, it was learned from the traffic police department of Guangzhou Public Security that in order to further improve the road traffic order and reduce the phenomenon of vehicle contention, Guangzhou traffic police set up an alternate intersection at the intersection of vehicles on the south-north straight ramp of Baihedong Interchange, and added alternate traffic signs and markings to guide vehicles to pass alternately.
Alternate traffic: A car on the right and a car on the left alternate traffic, also called "zipper traffic". As the name implies, when the number of front lanes decreases and vehicles queue up to pass, vehicles need to "zip", and one right and one left alternately enter the front lanes. After the implementation of this traffic mode, the traffic order at the intersection of vehicles can be effectively improved.
On the north-south straight ramp of Baihedong Interchange, we saw the effect after implementation.
At 3 o'clock in the afternoon on March 14, Guangzhou traffic police coordinated a construction team to come here and began to rebuild the ramp. Setting up roadblocks, drawing lines and painting ... After the guidance of the on-site police and the operation of the construction workers, the markings and signs on the driveway gradually appeared. Looking down from the top, you can see that the numbers 1, 2, 3, 4 and 5 are arranged in two lanes in turn, with auxiliary arrows on the ground, the words "alternate traffic" and "confluence intersection" "Alternate traffic" sign.
After the completion, it coincides with the increase in traffic volume. It is observed that compared with the phenomenon of disorderly lane change before the transformation, many vehicles have been able to merge into the lane in an orderly manner according to traffic rules, and the traffic order has been significantly improved.
"After several days of alternate traffic, preliminary results have been achieved." On March 17, officer Shen of Guangzhou Traffic Police Order and Facilities Brigade said that although this mode of traffic has achieved initial results, many car owners still don't know how to alternate traffic, and often change lanes in advance before driving to digital signs. Here, I appeal to passing drivers to observe the traffic signs and markings on the above sections. This year, the "double micro-transformation" of 24 key areas will be completed.
In order to improve the traffic order of urban trips, in recent years, Guangzhou traffic police have continuously improved the level of refined management, adhered to the concept of "small changes and great effects", and constantly optimized traffic facilities such as traffic signs and markings while exploring new applications of traffic signal control technology, and continued to carry out the "double micro-transformation" work.
In the reconstruction of the south-to-north through ramp of Baihedong Interchange, Guangzhou traffic police made a reconstruction plan of "alternate traffic" after on-the-spot investigation, combining with the road conditions of this section and adapting to local conditions. "The way of alternating traffic is not universal, and it is generally suitable for sections with relatively flat roads and wide horizons." Police officer Shen said.
According to reports, Guangzhou Traffic Police plans to complete the "double micro-renovation" work in 24 point areas this year, focusing on refined management of intersections, alternate traffic, slimming of major intersections and regional traffic organization.
