Automatically adjust the green lights according to the traffic flow!These sections of Xi'an have begun to implement

Driving driving all the way to green lights

According to the actual traffic flow

Automatically adjust the green light duration

Such a great travel experience

Some key sections in Chang'an District have been realized!

Recently, the "Xi'an Traffic Police Big Data+Signal Intelligent Tune System" built by the Xi'an Public Security Traffic Police will be officially delivered. On Chang'an District, it is on the road such as Xuefu Avenue and West Avenue. The duration has become shorter, and the sense of travel experience is significantly enhanced.

It is understood that the "Xi'an Traffic Police Big Data+Signal Intelligent Tuning System" can intelligently and quickly identify the green wave network, green wave trunk line, congestion trunk line and area, adaptive intersection and other optimized areas according to the dynamic changes in the traffic flow of the city's road network With nodes, based on the traffic changes of the road section, the signal is divided into refined time period, the recommended time scheme is recommended, and it is continuously optimized to iterate to output a variety of evaluation indicators.

Relying on the related functions of the tuning system, the traffic police department implements the "green wave belt" construction plan on Xuefu Avenue and Western Avenue signal lights.

The so -called "green wave belt"

In popular terms, driving forward at a certain speed, there is a great probability that you encounter green lights at each intersection, and if you keep this speed, you will have green lights all the way.

Western Avenue

Chang'annan Road -Shenjiaqiao 3rd Road Section

This section is one of the main roads in Chang'an District, and is the east -west artery of Chang'an District. Because there are a large number of transportation and attraction points such as commercial complexes, office buildings, and residential areas, traffic and flow of people along the line are in a high -dense state, and peak vehicle flow is large.

Based on the above characteristics, the relevant departments have set up "early peaks, flat peaks east to west of the east, and the west of the evening peak to the east." Before the implementation, continuous parking will occur during the section of the road, and the vehicle is prone to backlog. After the implementation of the green wave belt and optimization, the average number of parking times of vehicles has decreased, and the schedule is shortened. The characteristics of intelligence, dynamic, visualization, and humanization of the system play a maximum role, which greatly improves citizens' travel efficiency.

East Section of Xuefu Avenue (Shuxiang Road -Fundong One Road)

According to the staff of the Chang'an Brigade of the Traffic Police, the East Section of Xuefu Avenue (Shuxiang Road -Fundong One Road) set up a "two -way green waves throughout the day". After the implementation of the green wave belt and optimized, the number of parking times during the morning peak period was reduced by one time. 20.2%~ 26%; the number of parking times during the peak period was reduced to 0 times, and the itinerary efficiency increased by 42.1%. The number of parking east to east to the end of the evening peak period was reduced from 4 times to 1, the itinerary efficiency increased by 49%, the number of parking times east to the west decreased from 5 to 1, and the efficiency increased by 63%.
