Jinan: The traffic signal is multi -strategy to help the Mid -Autumn Festival travel smoothly

Qilu.com · Lightning News, September 8th, the Mid -Autumn Festival is coming. During the holidays, citizens have increased their travel needs such as reunion, short -distance travel, and visiting relatives and friends, and road traffic pressure has increased. In order to ensure the safety and smooth travel of citizens, Jinan Traffic Police rely on the traffic brain platform to conduct research and analysis of traffic situation around the holidays, formulate a diversion regulatory plan for the sendsing signal session in advance, and launch the special optimization of the Mid -Autumn Festival signal protection in the city. The traffic signal at 625 was adjusted.

Data support situation analysis

Analysis of previous years of data, the last working day before the Mid -Autumn Festival holiday in 2021 was 1.96, an increase of 37.1%from the previous week. The congestion index was 1.33, a year -on -year decrease of 7.80%. In view of the epidemic prevention and control situation, it is expected that the demand for vehicles entering and leaving the city in the Mid -Autumn Festival this year will increase compared with regular working days, but the increase will be lower than in previous years.

It is expected that from the afternoon of September 9th to the morning of September 10th, the main roads, transportation hubs, and road networks around the business district are busy. The traffic from September 10th to September 12th is relatively smooth. Scenic spots and business districts; from the afternoon of September 12th to the evening of the return trip.

Traffic congestion before and after the Mid -Autumn Festival

(1) Research and judgment of congestion before festival

Various types of traffic demand such as flow, school flow, outlets, and urban flow before the holiday are superimposed. The urban road traffic congestion index is significantly higher than the times. It is expected that the number of vehicles on the evening of September 9 will reach more than 660,000 vehicles. 15: 00-21: 00 The congestion index gradually rises and is in a state of slowing. The vehicle out of the city has increased significantly, especially at 16:30-20: 00 The urban area will be in severe congestion. Until 22:00 The transportation is basically returned to normal.

(2) Research and judgment of congestion in the section

On the whole, the traffic congestion status will be alleviated without working days in the city's urban area without working days. On the morning of September 10th, the outlet passage connecting the urban area and the major toll stations will be busy. From 9:00 to 11:00, it will be the peak of the high-speed outlet congestion. It is expected that to 12 o'clock, the traffic will gradually return to normal. From 14:00 to 20:00 pm, the public went to the business district's attractions to play and enjoy the moon. The traffic conditions in the urban area were slightly busy.

On September 11, the number of active cars in the urban area decreased significantly than usual, at the lowest point during the holidays, and the traffic conditions in urban road networks were in a smooth state throughout the day.

(3) Research and judgment of the situation of congestion at the end of the festival

Short-distance citizens generally choose to return after lunch or dinner. It is expected that the traffic flow in the city channel will increase at 15:00 to 22:00 on September 12th. The ring line is in a state of slow running, and then as the traffic flow gradually decreases, the traffic conditions in urban areas have fallen to a smooth state.

Transportation signal optimization guarantee

According to the data analysis and prediction data, the traffic police detachment formulated the signal control schemes in different time periods and different scenarios, and completed a total of 625 intersection of traffic signal matching scheme adjustment.

The first is optimization adjustment during different control periods. In response to the traffic situation at different periods before and after the Mid -Autumn Festival, the traffic signal control period and scheduling of urban traffic signal are adjusted from time dimension.

(1) Adjust the city's evening peak hours to 16: 30-20: 00 before the festival, and add 20: 00-22: 00 transition period scheme to match the cross-port signal cycle of the urban area and the traffic flow of the urban area to speed up Swire evacuation;

(2) In the festival, there is no morning and evening peak commute traffic. The urban signal control cross port is adjusted to holiday scheduling to reduce the signal cycle, driving delay, and improve the cross -port traffic efficiency;

(3) In response to the travel needs of citizens during the holidays, divide the control period of 19: 00-22: 00 separately, add green wave control plans to optimize the parameters of green comparison and phase difference to ensure the stability and reliable green wave effect stability and reliability sex.

The second is the traffic control mode. In order to cope with the rise in traffic flow before the surrounding roads, leading to saturation and overflow, the control strategies such as timely optimization, path coordination, and overflow prevention and control are taken.

Take Jinan Station as an example. First of all, adjust the peak hours of the three key nodes of the station roads, Jingyi Road, and Jingcheng Road. From 16: 30-19: 00 , Adapt to changes in traffic; at the same time, increase the green light time of the north mouth of the intersection of the station street for 10 seconds, and improve the efficiency of the vehicle exit vehicles; second, adjust the signal phase and green letter comparison of the Tiancheng Road intersection through the 1st road, and control the vehicles entering the west exit. Avoid the overflow of the lack of space for west exports; in the end, the cross -port along the road and the second road of the Weier Road takes green wave control, reduce driving delays, improves the efficiency of road sections, and speed up the traffic in large stocks to quickly dissipate.

Third, the signal control mode around the business district. Optimize control strategies such as external control internal control, balanced vehicle flow, node optimization, and clearing protection in the surrounding sections of the business district.

Take Quancheng Road Business District as an example to adjust 6 key nodes in the six borders such as Chaoshan Street, Quancheng Road, Quancheng Road, Quancheng Road, Quancheng Road, and Quancheng Road Qinglong Bridge. Add 8 seconds to the intersection of 3 intersections at the intersection of Shunjing Street, Quancheng Road to prevent the intersection from inserting the market. Finally, the three short -distance intersection of Shunjing Street, Qianqian Street, and Provincial Fuqian Street along Quancheng Road Take one -way large bandwidth coordination and linkage control to improve the efficiency of road sections.

Fourth, the signal control mode around the scenic area. Taking the Daming Lake area as an example, the "external control and internal sparse" control strategy is optimized aiming at the problem of congestion caused by the concentration of travel needs of the scenic area. Taking the traffic thermal source area as the center, the two "regional signal control boundaries" in the inside and outside control the flow of key nodes in and out of the key nodes in the interior and outside.

Fifth, the traffic corridor signal control mode. Optimize long green wave control technology for entering and leaving the city passage and trunk roads. Taking the eastern section of the Shilu Road as an example, in order to reduce the traffic in the city and ease the traffic pressure in the urban area, the "priority of the city" signal control strategy is adopted to take a unidirectional green wave control scheme for the direction of the west direction to the east. From Hongshan Road to Tangye West Road does not design parking all the way, the vehicle is released in the city in the fastest and most efficient way. For the direction of entering the city east to the west, segmented coordination control is adopted. Design parking at the intersection with large locations such as Fengqi Road, Fengshan Road, Shunhua Road, Olympic Middle Road, and Quanshan West Road design parking, delaying the time of entering the city, reducing the density of vehicle vehicles in the urban area, and alleviating traffic congestion in urban areas.

In order to ensure the smooth operation of the urban roads around and after the holiday, the traffic police detachment scientific research institute has established a working mechanism for "all day on duty, internal and external linkage". Inspection. The personnel on duty will dynamically adjust the traffic signal time plan according to the changes in traffic flow, and make every effort to ensure that the citizens travel smoothly during the holidays.
