It has been tested at four intersections in the High-tech Zone. In the future, the best avoidance route can be checked online.
Regular pieces. It refers to parts that are often used, such as high frequency, large loss of equipment and cheap univalent, such as vulnerable parts, large consumption parts, and key equipment, and so on.
(2) very spare parts. Parts with low frequency, small stop loss and expensive unit price can be divided into plan purchase parts: purchase parts in advance for short-term reserves according to repair plan, purchase items at any time before repair, or parts that are used immediately after manufacture.

According to real-time traffic flow on the road and surrounding areas, traffic lights can be automatically adjusted; the Internet can not only see which roads are jammed, the system can automatically configure the optimal travel route ... Yesterday, the reporter from the International Conference on Intelligent Transportation in China held in Hefei It was learned that at present, the construction of the Hefei intelligent transportation system is continuously improving, and in the future citizens will enjoy the convenience brought by more intelligent transportation systems.
[Treatment] Experts say that it is particularly important to improve public transport
It is understood that the current number of motor vehicles in Hefei has exceeded 800,000. The traffic flow of a road in the peak hours of traffic has reached or even exceeded saturation, and traffic congestion has occurred from time to time, and it has been increasingly intensified. Several experts attending the meeting stated that it is particularly important to improve public transport in order to “treat†the problem.
Wang Yunpeng, Dean of the School of Transportation Science and Engineering at Beijing University of Aeronautics and Astronautics, says that Hefei is similar to Beijing and other cities. Even fast roads, such as the morning and evening peaks, are even more congested than light-controlled roads. This is due in large part to imperfect public transportation. Public transport is perfect, especially if we can combine slow vehicles such as bicycles so that people can get home directly. This will greatly ease traffic congestion in the loop and even in one area."
Li Keping, a professor at Tongji University in Shanghai, also stated that the rail transit currently under construction in Hefei will improve this situation very well. “Public transport plus rail transit, we believe that congestion will be effectively relieved.â€
[Experiment] Traffic lights will be automatically adjusted according to real-time traffic conditions
The reporter was informed that at present, a new traffic signal control system is being tested at Huangshan Road in Gaoxin District, Xiangxi Avenue, Science Avenue, Tianzhu Road, and Science Avenue and Tianhu Road. The system collects real-time data on the road surface. , such as traffic flow, road resources, etc., and then automatically adjust the signal lights according to actual needs, "For example, here is blocked, the system will automatically learn, and then according to the judgment of the global traffic conditions, automatically adjust the signal lamp cycle time." Preliminary As a result of the experiment, the vehicle delay time can be reduced by 25%, which greatly improves the traffic efficiency.
At the same time, there are more than 100 crossings in the High-tech Zone to build a signal timing system. “This is based on our previous analysis of the overall road conditions, and then according to different time periods, the signal lamp cycle is set in advance, and then the signal lamp will be set according to the settings. Automatic adjustment.†Experts said that, for example, what is the signal period of a peak traffic hour and what kind of cycle signal light cycle period the system should adjust automatically.
[Service] can automatically configure the optimal route to avoid blocking
Experts at the meeting stated that the construction of the intelligent transportation system not only optimizes the conditions for road access, but also provides a lot of convenience for the citizens to travel and analyze the big data. A participating expert said that at present, a company in Hefei has developed a new technology that can automatically configure the optimal travel route and avoid blocking points. “At present, some APPs provide only information on which roads are plugged, or where they come from.†According to experts, it is possible that the roads are blocked even though they are the nearest line, or the owner knows that the road is blocked. , but do not know how to get around. After the introduction of this new technology, citizens can inquire before they travel, and the system will automatically plan the optimal route in combination with all blocking points, and choose the nearest bypass line while avoiding all blocking points.
In addition, with the construction of intelligent transportation, the more the summarization of big data, it can also provide data support for the analysis of the situation at each intersection. For example, the traffic accident black spots map of Anhui Province in 2013 published by the traffic police department has been summarized. Which sections of the province are prone to traffic accidents is the data support provided by intelligent transportation.
In addition, Hefei will launch an on-site vehicle maintenance service appointment in the near future. The owner only needs to provide vehicle brand model, mileage, status and other information on the Internet. The relevant company will visit the vehicle at the scheduled time and the cost will be lower than the overall cost. market price.
