Urban traffic management into the era of intelligent

   Traffic signal machine: urban traffic management into the era of intelligent

   With a total investment of more than 2300 million yuan, known as "Skynet" project of a companion of Tai'an intelligent traffic signal control system officially opened on August 19. This means that the vast majority of the intersection of the signal machine and signal lights to achieve the upgrading, marking the Tai'an traffic management work has entered a new stage of modernization, intelligent development.

   Capacity of urban road network near saturation

   In recent years, with the rapid development of Tai'an's economic and social development and urbanization, the population size and the rapid growth of the vehicle population in thailand. As of now, the Thai city urban resident, temporary population of about 720000, the amount of vehicle more than 50, and the average annual growth rate of 20%. In addition to the Thai city board type road network structure characteristics, the central area and the main road traffic continues to increase, morning and evening peak hours gradually extended, high traffic flow, the current urban road network capacity has been mostly saturated and nearly saturated state.

   Taian as an international tourism city, the annual reception of domestic and foreign tourists more than 5300 million people, among them into the mountains, into the tourist attractions of 550 million people, the resulting import and Thai city vehicles of more than 120 million vehicle timeses, traffic organization difficulty further increase.

   Although the government in the combination of urban road network expansion, alteration, and the addition of a number of signal and signal lights, but overall, the traffic signal system based on basic is very weak. It is understood, until 2014, Thai city traffic signal control intersection a total of 121, which can be connected to Internet, carries on the coordination control of only 32, most road junctions to single point of timing control, not from a macro were flow regulation.

   Taian city traffic police detachment Wei Zhaode introduction, Shudu Chang has become the difficulty of Party committee and government pay attention to the key, the masses of the people attention and the focus of the transportation departments to crack, it is urgency to improve the intelligent level of traffic control and guidance.

   Upgrading and transformation of 99 signal machine

   December 2014. The total investment of more than 2300 million yuan, known as Skynet project of a companion of intelligent traffic signal control system officially started construction. This system mainly consists of three main parts, which are signal control center, traffic signal control unit and data transmission equipment.

   Major construction projects unified signal control center system platform, to 134 intersection signal and the signal lamp transformation; new 13 intersection signal control system; to 121 intersection refurbished signal lamp pole, 98 intersection installation key node in the geomagnetic equipment and 16 urban trunk road installation of traffic guidance display screen.

   According to Wei Zhaode introduced, in accordance with a design, step-by-step implementation of the construction principle, the first to the east from Bo Yang Road, West to the Peach Garden Road, north from the ring road, South to the traffic signal control system of traffic signal control system to upgrade, and through the gradual expansion, and ultimately achieve the main intersection of the Thai city wide coverage.

   After more than eight months of construction, at present besides Pan River Street due to closure of roads not for construction and two regional signal property does not belong to the detachment, Thai city urban district 99 intersection traffic signal machine, 30 at the junction of the geomagnetic sensor, 77 intersection signal lamp stand over the key node in the new and 5 trunk road traffic guidance display installation work has been completed, the traffic signal control system also and the detachment system integration platform, realize the butt.

   The city roads can be set up "green wave band"

   "Traffic signal control system enabled marks urban traffic management work entered a new stage of intelligent and modernization, is the smooth construction of Taian, Ping An of Taian new starting point, which is bound to mention the city's traffic management upgrade lay a solid foundation, to provide strong support." Ju Xiangqun, vice mayor of Tai'an City, attended the opening ceremony of the system to say.

At present, the Thai city traffic signal intelligent control system has been officially put into operation, the road traffic signal system, the public security traffic management information, intelligent level has been significantly improved.

   "Now, in the center of the command center system a management platform, can let more than 20 users to the Thai city most of the signal lamp for real-time visual monitoring and parameter remote set, greatly improving the road traffic management work efficiency." Wei Zhaode said, now we can according to different regions, different periods of traffic flow and road network to implement different control mode."

In the case of Dongyue street, in the morning and evening rush hour, the traffic police can be set through the road of "green belt system". Driver to about 50 km / hour speed driving in the Dongyue street, when catch up with the first light, at this speed continue moving forward, met the following intersection is also a green light. "This is the effect of the trunk coordination control." Wei Zhaode said that this control mode can not only to provide services for the transport security, emergency rescue, at the sudden emergency such as "green light", but also by setting the "red zone", on suspicion of violation vehicle surveillance.

Install new traffic guidance display have been through network are connected to the command center system platform to will traffic status of the surrounding area and the road in front of the main transport node and is expected to reach real time release, guide the driver to choose the best route.
