Nanchang traffic lights intelligent street lamp set is not enough, control methods

Traffic lights, is the guarantee traffic safety, open the necessary traffic facilities, due to various reasons, the lights of the city control mode is relatively backward, and in 460 in the city intersection signal lights, only 68 intersection signals to implement the intelligent control, proportion only

traffic lights is necessary to ensure smooth traffic safety and traffic facilities. Due to various reasons, nanchang light control method is relatively backward. 460 traffic lights in the city, only 68 sets have been intelligent control, accounts for only 14. 8%. In order to further improve the level of the use and management of nanchang city traffic light, the traffic administrative department of the nanchang since May 27 is installation, use and management of traffic lights to solicit public opinion and the suggestion. Smart cover less than we have learned, nanchang 460 traffic signal intersection, 189 of which are controlled by single point fixed periodic signal. 271 intersections controlled by intelligent network signal, of which only 68 intersections with high intelligence, such as dynamic green wave band, fixed cycle green wave band, and a single point of adaptive, single point induction, bottleneck control, etc. Closely integrated with the actual traffic management. The intersection of other interconnected still controlled by single point periodic because there is no support from vehicle flow detection data. The relevant person in charge of nanchang city public security traffic management bureau said: in general, nanchang signal control method is relatively backward, the control methods need to be improved, mainly flow detection method can't keep up. ； Are interested in purchasing professional services; We suggest the government to increase funding. ； The relevant person in charge of traffic management bureau, said signal system construction this year will be the major key projects to declare one of the key direction. In guarantee vehicle traffic parameters such as flow, speed, occupancy rate under the premise of accurate and reliable, strengthen using adaptive dynamic green wave control, single point control, single point induction control, bottleneck control and demand control, more intelligent, more practical, more management oriented control method, make the signal control and signal timing is more scientific and reasonable. Besides requires light pole companies to increase capital investment, transportation authority also plan to purchase a third party through the road of socialization service specialized company, the key to solve two problems: one is the main typical intersection traffic signal control system to carry on the fine channelized traffic organization design, set up the pedestrian crossing facilities. Intersection by investigation and argumentation, the second is to optimize and adjust the signal control mode and timing plan. Ben Mr Zhang source: shandong siao traffic lights factory. yhjtqc。 com
