Optimize 343 signal control intersection, Jinan traffic signal light starts "opening school"

The summer vacation is close to the end. On September 1st, the city's primary and secondary schools will be held. After the start of school, traffic traffic around the school will increase significantly. On August 29, a reporter from Xinhuanghe learned from Jinan Traffic Police that relying on the traffic brain to study and judge the changes in traffic flow, the traffic police department formulated a "one school, one strategy" refined signal matching plan, and comprehensively launched the traffic signal light "school".

It is understood that in order to accurately predict the changes in the traffic of the main roads in the urban area after the start of the school, and to formulate a scientific and reasonable signal optimization strategy, Jinan Traffic Police analyzes and judged the traffic situation of this year's opening season this year.

In terms of time dimension, the traffic flow after school will present the following two characteristics: First, the congestion status of the morning and evening peak hours will intensify. Due to the peak commuting commuting and students' school time over school, the traffic pressure during the peak hours of the urban area will further intensify, and the peak average of peaks will be average. The congestion index is expected to increase by 35.68%. Second, the duration of congestion during peak hours is prolonged. The first week of school is expected to be advanced from 7:40 before school to 7:00 before school. Increase.

In terms of space dimension, the traffic situation of the road network and urban main roads around the school after the start of the school will present the following characteristics: First, the traffic of the surrounding road networks has increased significantly, and traffic pressure increases. It is expected that the average congestion index around the school's surrounding road network will increase by 42%compared to before school. Increasing; Jinan Shengli Street Primary School's two roads in the Eighth Road and Minsheng Street in the morning and evening peak congestion will be significantly intensified. Second, the traffic flow of the main roads in the urban area shows an upward trend. Compared with the simple commuting needs of the summer, after the school starts, the parents of students will increase the winding distance and occupying the road network for pick -up students. The length of the main roads, the schedule, the number of parking times, and the delay of driving delays in the main roads of the city areas such as Shilu, Olympic Middle Road, and tourist roads will increase significantly, and the phenomenon of slowing will occur. Taking Jingqi Road (Weili Road-Weiba Road) as an example, according to data analysis in previous years, the first week of school was compared with the normal working week, and the average driving delay during the early peak hours increased from 78.76 seconds to 150.54 seconds, an increase of 91.36%.

In order to ensure the safety and smooth travel of citizens after school, the Jinan Traffic Police Detachment set up a signal optimization plan in advance based on the traffic situation analysis and prediction data. Optimization of signal control cross port.

First of all, targeted optimization around the school. Taking the surrounding road network integrated area as the object, analyze the main traffic flow and internal evacuation paths of the area in and out of the area, and in accordance with the balanced traffic flow, safe and smooth control goals, Jinan traffic police through control periods, key nodes optimization, road section green wave coordination, etc. The measures were comprehensively improved, and a total of 133 schools were adjusted during the intersection of 133 schools. Taking the intersection of Qi Road Weiyi Road as an example, the traffic on the east exit of the intersection at the intersection and the traffic of the north exit of the north will increase. Students' traffic is quickly evacuated.

Then there is an in -depth optimization of the main road network of the urban area. Considering the sharp increase in traffic flow, a large number of road construction will seriously affect the driving experience of the green wave belt. Jinan Traffic Police deeply optimizes the green wave control of the main road in the urban area. According to the dynamic time of the key intersection of the key intersection, the signal of the key intersection is dynamically adjusted according to the queue length and the road section driving speed changes. Leading lane guidance, reducing driving delays, ensuring the coordinated control effects between intersections, and improving the urban road network traffic efficiency. A total of 22 roads such as Heroes Mountain Road, Jingqi Road, and Cishan Road are optimized and adjusted.

At the same time, Jinan Traffic Police warmly reminded teachers and students and parents to travel green. Parents are particularly reminded that when they pick up students, they can drive civilized driving, stop, and leave, polite pedestrians, and consciously maintain a good order.

1. Choose a green traffic method

If the travel distance is not far away, parents can choose non -motorized vehicles, walking and other methods to pick up children, which can effectively avoid traffic congestion of motor vehicle, and it is more convenient to travel.

2. Reasonable planning travel route

Please pay attention to transportation travel auxiliary tools such as transportation, road traffic induction screens, navigation software and other traffic travel auxiliary tools in time.

3. Try to choose the peak peak travel

In order to slow down the overlapping traffic congestion, it is recommended that the citizens avoid the peak of traffic and choose the peak peak. After the start of school, the traffic around the school will gradually rise around 6:55.
