At presentthe industrial north road to the Olympic Fuk overpass east 4 kilometers whole sections completed 10 signal lamp signal timing optimization ,vehicle travel time shorten .( Cui Jian .
) “ ;green wave band ” ;control model of traffic signal coordinated control system is a way of .The so-called green wave band “ ;” ;is based on vehicle road speed and the junction with the distance between the junctions ,within the control of the signal ,settings are controlled by the mainstream vehicle arrives at each intersection signal lamp lighting time difference ,so as to ensure the vehicle from the first green light started only in accordance with the provisions of the average speed after this encounter ,all lights will be full of light .
From the control path of each intersection point of view, the green light waves billowing ,so experts were called “ ;green wave band ” ;.Block has become each big city commonly faced problems ,and “ ;green wave band ” ;is many people have high hopes .
Reporters today learned from the traffic police department ,the industrial north signal timing optimization has been completed ,the city added a “ ;green wave band ” ;.Optimal signal timing block in recent years ,with the amount of motor vehicle increases dramatically and the city of East extension “ ;” ;process accelerating ,the industrial north to become our city east of the city through the east-west trunk road ,which along with many large factories ,commercial shopping place and 15 middle schools and primary schools kindergarten ,together with is located in urban rural fringe, bazaar and many surrounding large vehicles ,road, branch lead in all directions ,resulting in the peak morning and evening ,weekend and holiday traffic pressure is great ,serious impact on the smooth flow of road traffic safety .
In order to facilitate the masses daily travel, traffic police brigade in the traffic police detachment of research institutes ,many organizations in-depth sections surrounding research, after 1 months ,a lot of experiments and adjustment ,completed the industrial north Quanfu bridge east to the Olympic road 4 km journey ,10 signal lamp signal timing optimization .
According to introduction ,after the experiment, the green wave band “ ;” ;when completed, from west to east to the peak time from the original 21 minutes ,shortened to now 9 minutes 30 seconds; flat peak from the original 13 minutes 30 seconds ,shortened to 7 minutes 30 seconds now .
From the east to the West peak time from 19 minutes to 12 minutes ,shorten now ;flat peak from the original 13 minutes to 8 minutes ,shorten now .Considering the Friday afternoon school students ,shuttle vehicle centralized ,on Friday at sixteen thirty to eighteen thirty time slot to take special timing ,timing from east to west direction from the original 50 minutes ,shortened to now 35 minutes ;from west to east direction from the original 35 minutes ,shortened to 20 now minutes ,the industrial north road traffic efficiency improved significantly .
Reporters in the field experience “ ;green wave band ” ;this morning, reporters drove to Fuk overpass ,from west to east to experience this new “ ;green wave band ” ;.
Ten thirty-five ,the reporter arrived by car to Fuk overpass ,in the first junction processing junctions encountered a red signal ,green light ,30 seconds to reach the second junction to build electric junction, about ten thirty-eight at third junctions return at the junction ,meet again a red light ,wait about 30 seconds after the lights turn green ,then ,by reporter vehicle 50 km per hour speed along the road ,about ten forty-three at the junction of tenth Olympic road junction ,with a total of about 8 minutes .
And the traffic police department to provide data consistent .Reportedly ,the current calendar ,traffic police brigade of Olympic road to tempered road 5.8 km ,7 signal distribution also has made the adjustment .
At present, from west to east to already by original 10 minutes ,shortened to 7 minutes and 50 seconds ;from the east to the West from the original 8 minutes ,shortened to 6 minutes and 30 seconds .
Members of the public to actively participate in Licheng Traffic Police Brigade police introduced ,in the industrial north green wave band “ ;” ;construction process, many members of the public to actively participate in .
Engaged in the construction industry of Mr. Wang of the public to take the initiative to contact the police ,actively put forward their views and suggestions .Mr. Wang said ,he of the traffic jam phenomenon has been studied for many years ,the last one of his research is to apply for a patent .
Mr. Wang said ,after the transformation of the industrial north will bring great changes in four aspects :one is the effective solution to this main road traffic jam ;two is the vehicle in a safe speed running ,reduce traffic accidents ;three will bring huge economic benefits ,according to his calculations ,with the Olympic Road eastbound 3.
5 kilometers section for example ,each car can save 4 minutes a day ,according to the passage of the 30000 cars ,each car an average of 2 people per day ,time cost is calculated 100 yuan ,a year down ,only artificial cost can save you thousands of dollars ;four is shorter by time will reduce fuel consumption ,is conducive to the protection of atmospheric environment .
With real “ ;green wave band ” ;and from February 24th ,the Municipal Public Security Bureau Director Liu Xinyun said ,by ten road will build “ ;green wave band ,” ;some sections will be using “ ;” transform lane ;way of relieving traffic congestion .
I have been in part before city trunk road “ ;green wave band ” ;,the effect of good .However ,once the traffic flow volume, speed slow ,signal timing is still in accordance with the previous settings ,often resulting in design of green light into a red ” “ ;.
So the construction of the “ on real significance ;green wave band ,” ;is not a one-time modification of crossing signal configuration ,but to signal lamp optical cable laying ,networked control ,according to the vehicle flow stochastic optimization configuration .
Taking Beijing as an example ,relying on the traffic monitoring data ,Beijing built the traffic signal control system ,as a center of the brain ,real-time adjustment of the traffic lights at the junction with the .
Data shows ,“ ;green wave band ” ;implementation needs to consider many factors ,because of its technical requirements and the actual road traffic and other factors ,to achieve greater difficulty .
Therefore ,not every line suitable for green wave control ,but in the proper way, green wave control than the simple point timing control traffic more efficient .Administration block application of divergent thinking in block is a difficult problem ,need each respect brains, more use of divergent thinking to solve the problem .
Liu Xinyun expresses ,will pass through the road lights indicating the direction change ,control of trunk road lane direction ,to adjust the number of lanes, improve the use efficiency of lane .
For example ,the morning one road ,to the south direction of the vehicle ,can increase the sections south direction lane ,reduced northward direction lane way ,alleviate the traffic pressure .
Evening peak time can take the opposite lane allocation to divert vehicles .According to introduction ,“ ;” transform lane ;rational use of limited road resources ,for example ,a left turn lane is crowded ,but straight lane car less smooth ,traffic light controller ,in less than a minute ,straight lane into a left turn lane ,left-turn vehicle dragon “ ” ;digestion ;,driveway with the traffic flow changes with time .
Recently, the netizen that by four weft two junctions, traffic police command in the vehicle when “ ” ;secret ;,can let the vehicle during the rush hour rapid through ,and praised the intersection traffic police “ ;is a talent ,intelligent ” ;.
Netizens “ ;clever brother ” ;,is the City Traffic Police Battalion two weft Road police squadron he Yanfeng .He Yanfeng direct method is ,early peak time ,turn left turn to turn the vehicle forward guide ,from the four or five to guide its listed separately in a row, peak periods can list three rows of left turn to transfer vehicle .
Using this method, originally a signal lamp can have 15 or so cars through ,now a signal lamp can release a 1934 .In addition ,in the main road layout variable information board ,except through a graphical way to smooth ,slow ,congestion level three to release real-time traffic information,www.hollisteremagasin4fr.com, but also through writing published accident ,control ,construction ,publicity and other traffic information ,guide the driver to adjust the route ,achieve equilibrium network flow ,remission traffic congestion in .
Also in Beijing for example, variable information board display of real-time traffic information .Slow driving routes ,with yellow ;green represents more than 50 kilometers open road ;and the red ,it means the road congestion ,to remind the driver in a roundabout way .

Voting is expected to close by 5:00 p.m. (1700 GMT), according to the electoral laws of the country. However, there is a growing fear that voting might travel late into the night, following widespread reports of faulty machines. But the Electoral Commission (EC) has assured registered voters in polling stations where voting did not start early due to the late arrival of election materials, that the commission has an inbuilt mechanism that will make it possible for all eligible voters who are in the queue before 5:00 p.m. (1700 GMT) to vote.
