The intersection of Hongzhaobi is located on the central axis of Chengdu, Sichuan Province. It is adjacent to Tianfu Square and is the main road for traffic entering and leaving the city. The traffic pressure in the morning and evening is huge. Now, in the four directions of the intersection, there are “straight-forward waiting areas” and “left-turn waiting areas”, which are quite impressive from the high point.
What is the effect of setting up the “going straight-forward zone”? Recently, the National Urban Road Traffic Organization Optimization Work Conference organized by the Traffic Management Bureau of the Ministry of Public Security was held in Chengdu. More than 100 people from the traffic control departments of Beijing, Tianjin, Hebei and other provinces and municipalities listened to Chengdu traffic police to talk about “management of the Jingjing”.
“The traffic volume passing through the four directions in the four directions is increased by about 10% per unit time, and there are more than 640-800 vehicles per hour at the intersection.” The traffic police, who is on duty at the intersection of Hongzhaobi for many years, is the deputy commander of the second brigade, Xie Peng. I know the situation here.
At present, more than 85% of the intersections in the downtown area of Chengdu are in a saturated state. To this end, the traffic police department implements the “direct travel zone” traffic organization mode at some intersections in the central city, and maximizes the effective time and space of the intersection through the secondary distribution of time and space resources at the intersection, realizing the intensive use of intersection resources. .
The intersection of the intersection is so fine "embroidery", what good strategy to crack the congestion in the large business district? How to crack the "blocking" around the hospital?
The average daily passenger flow in the Taikoo Li business district is about 110,000 person-times, and the weekend is as high as 130,000 to 150,000 person-times. The high popularity has brought huge traffic attraction. Jiang Cheng, deputy director of the Traffic Police Third Branch, introduced that for the special geographical location of the business district, the taxis and the networked vehicles are “stop-and-go” berths, and the travel information is released dynamically. It is clear that the loading and unloading area of the truck is located in the underground parking lot; in the main road of the commercial circle, the yarn hat street, two wide crosswalk lines are arranged, and the pedestrian pedestrian signal timing is optimized, and a new pedestrian crossing voice prompting system is introduced. “At present, the road traffic operation in the commercial district has remained stable, and the traffic congestion index on holidays has decreased by 8% year-on-year.”
For the first time, in the small and medium-sized streets that are required to enter and exit Huaxi Hospital, Telecommunication Road, set up bus lanes; adjust the location of bus stops, coordinate the opening of three dedicated buses, and strengthen the connection with subway and BRT BRT. Make full use of the Huaxiba underground space to achieve convenient conversion between the peripheral parking and the hospital, and reduce the total traffic volume in the hospital area. Set up two medical treatment lanes on the telecommunications road, set the emergency ban area to ensure the smooth passage of life channels.
In the past, the most blocked telecommunications roads have been set up for bus lanes. The bus operation speed of this section has increased from 1 km/h to 16 km/h, the peak turnaround time has been shortened by 30%, the number of vehicles has decreased by 15%, and the public transport sharing rate has increased. Two percentage points.
In addition, the Chengdu Traffic Police also established a big data thinking, actively explored the new model of "Internet + traffic management", and initially realized the use of data decision-making, data management, and data innovation. In July last year, the Chengdu Traffic Police launched the “Rong Exing” Traffic Public Welfare Alliance Platform in the country, providing a number of functions such as traffic violation reports, traffic safety facility failure reports, traffic organization optimization recommendations, and private car parking declarations.
