Big change!260 intersections in Hefei

Recently, the "Suggestions on the Peak of Road Conditioning During the Peak Traffic Sign Lights" proposed by Liu Dajun, a representative of the People's Congress of Hefei City in the action of "gathering public opinion and benefiting people's livelihood", the Hefei Public Security Bureau Traffic Police Detachment revealed that this year's traffic police detachment formulated The "Work Plan for the Matching Signaling Signal Signal in 2022". According to the plan, the 9 administrative regions of Hefei will select 52 roads to a total of 260 road design green wave programs in accordance with road conditions and traffic characteristics before the end of the year.

Suggestion: Big data analysis of car traffic is good

Liu Dajun proposed that the ranking of the Urban Transportation Health Index in Hefei continued to rise, and the ranking of congestion declined year by year.

After that, it is recommended that the big data analysis of the traffic flow can be used to select different traffic traffic lights in time according to different traffic levels. Mitrate the congestion by extending the release period of the congestion direction, setting up the variable -passing lane in the period of congestion.

At the same time, the traffic junction scheme scheme of peak congestion and congestion points is set up targeted, and timely adjustment is made in time according to the actual road conditions. In addition, you can collect traffic data, use big data to make overall analysis of the city's key congestion points, and provide reference suggestions for urban road construction departments.

Work: A total of 1231 key intersections have been completed

Regarding Liu Dajun's suggestion, the Traffic Police Detachment of the Hefei Public Security Bureau replied that the traffic police detachment had established a traffic signal time center center in 2020, and established a three -level linkage working mechanism for detachment, brigade, and squadron signal. At present, the team is currently the team. At the beginning of the scale, eight team members have graduated from traffic engineering and traffic signal control related majors.

As of now, the Mixing Center rely on the three -level linkage work mechanism to jointly complete the city's 2,400 intersection basic information archives with the city's traffic police brigade and squadron. Diagnosis and analysis of key intersections in the urban area analyzes the problems and possible causes of the intersection congestion, overrouts, and overflow, and put forward corresponding suggestions for improving.

Combined with the diagnostic analysis report, the cumulative center of the center has completed the single -point optimization of 998 congested intersections, the optimization of 1231 key intersections, creating a traffic wave belt for transportation, and completing 34 total 55km green wave optimization, as well as the city's 586 road right to control the control. Effectively improve the safety of the intersection.

Future: Select 260 intersection design green wave programs before the end of the year

Recently, in order to ensure the scientific and reasonable time of the city's key intersections, the traffic police detachment carried out the key work of the key intersection, and used the Hefei Urban Transportation Ultra -brain Platform to conduct statistical analysis of car traffic data on key intersections. Aiming at 182 key intersections in the city's jurisdiction, a refined matching scheme is set up to improve the intelligence of red and green lights.

In 2022, the traffic police detachment formulated the "Work Plan for the Matching Signaling Signal Signal Signal in 2022". Based on the planning of the 9 administrative regions of Hefei before the end of the plan, 52 roads were selected in 52 roads to design a green wave plan in accordance with the road conditions and traffic characteristics.

At the same time, we will strengthen the intelligent construction of the signal matching time. The "adaptive" algorithm is selected in each region to select the "adaptive" algorithm to make the signal with the vehicle traffic independent production time scheme. It is expected Reduce the red light waiting time of the main road vehicle, improve the average speed and traffic efficiency of the main roads, the main roads, and improve the comfort and happiness of citizens' travel.
