Baoding has built 45 green belts to create a model city for "smart transportation" in the north

On December 12 , the Baoding Traffic Congestion Digital Research and Governance Center was officially unveiled. The center was jointly established by the Traffic Police Detachment of the Baoding Public Security Bureau, the Municipal Urban Management Comprehensive Administrative Law Enforcement Bureau, Tsinghua Tongheng Planning and Design Institute, Baidu, and Daily Interactive. Daily Interactive's smart transportation ecosystem company Yuntong Shuda is deeply involved and fully assists the Baoding traffic police in continuing to carry out congestion control work. The center will gather digital intelligence forces from multiple parties, comprehensively upgrade Baoding's "intelligent signal control" application new means, realize the construction of the city's "full-area green wave", and provide guarantees for the safe, smooth and convenient travel of the people.

45 green waves are connected in series to form a network, and the travel time is reduced by 5.16%

With the help of digital intelligence technology, the Baoding Public Security Traffic Police, in conjunction with the center's member units, analyzed the traffic situation and flow characteristics of roads across the city. Based on factors such as the traffic flow direction, flow change patterns, and intersection spacing, they recommended suitable green wave roads and tailored intersection coordination plans for each green wave road to adapt to the traffic characteristics of different time periods such as rush hour, off-peak hours, and night, so as to reduce the probability of encountering red lights at intersections and ensure "smooth travel."

At present, 45 green wave roads have been built in the main urban area of ​​Baoding, 231 intersections have been coordinated, the average passing time of green wave roads has been shortened by 5.16% , and the road congestion index has dropped by 5.06% .

Reduce parking times and improve driving experience

Based on the digital traffic model jointly established by the center members, the Baoding Public Security Traffic Police built intersection portraits for all intersections in the city and deeply analyzed the changes in traffic characteristics at the intersections. Relying on the intelligent signal control platform, through video traffic collection, the queue length is perceived, and adaptive signal control is achieved, with an average daily adjustment of the signal control plan exceeding 10,000 times. When these two technologies meet, thousands of intersections can be coordinated comprehensively.

Taking Dongfeng Road, an important commuter trunk road in Baoding City, as an example, the road is about 12 kilometers long and has 20 intersections. There are shopping centers such as Wanbo Plaza and Dongfeng Commercial City on both sides of the road. It has important transportation functions and is a key target for optimization.

Although Dongfeng Road already had an adaptive green wave solution in the early stage, the Baoding Public Security Traffic Police found through the intersection portrait data analysis that there is still room for improvement on Dongfeng Road. Through data analysis, the Baoding Public Security Traffic Police dug deep into the road demand of Dongfeng Road, further clarified the key points of optimization of Dongfeng Road at different time periods, and iterated the green wave solution.

After optimization, the overall speed of Dongfeng Road increased to 44.1km/h , an increase of 6.01% . During the off-peak period, the number of stops on Dongfeng Road in the direction of the city (east to west) dropped from 7 to 4 , basically achieving "green lights all the way" through 4 to 5 intersections in a row, and the probability of stopping dropped by 42.9% .

Urban transportation is closely related to social livelihood. Even if you encounter one less red light on the road, it can add "acceleration" to the city's economic development and bring a sense of happiness to citizens. As a member of the Baoding Traffic Congestion Digital Research and Governance Center, Daily Interactive will focus on the mining and application of traffic data value, empower the digital and refined development of Baoding's urban traffic management, and let citizens feel the "digital" degree of travel.
