A real-time vehicle speed control method in subway construction area

Abstract

The invention relates to a subway construction region real-time vehicle-speed control method. Relevant data, such as rainfall, a vehicle flow and a fact that whether a traffic accident occurs, of the surrounding of a subway construction region are acquired in real time, a decision tree method is adopted, classification and identification are performed on a present traffic condition of the subway construction region, appropriate adjustment for a vehicle speed limit value is performed according to an identification result, information sending is performed through a variable information issue system, relevant personnel and surrounding motor vehicle drivers are timely notified, and the object of reasonable vehicle flow guidance is finally achieved. A plurality of factors influencing the subway construction region are selected, the decision tree method is adopted, real-time adjustment for the speed limit value of the surrounding of the construction region is achieved, and the vehicle flow can be effectively guided to operate according to reasonable speeds.

Description

technical field [0001] The invention relates to the technical field of subway construction management, in particular to a real-time vehicle speed control method in a subway construction area. Background technique [0002] The existing traffic management method in the subway construction area is mainly composed of some fixed speed limit signs and safety warning signs and other facilities, which are relatively simple to set up in accordance with relevant traffic regulations. The feature is that the overall construction cost is low, mainly for relatively stable and changing environments. Not a big case. The disadvantage is that it is not sensitive to environmental changes in the subway construction area, and it cannot release variable information based on real-time information. Frequently, the prompt information is inaccurate and the driver does not pay attention to it. Traditional subway construction management methods are difficult to reduce the incidence of traffic accident...

AI Technical Summary

Problems solved by technology

Coupled with the non-standard operation of some subway construction units, traffic planning and management measures are not in place, resulting in more chaotic traffic control in the subway construction area, and the subway construction area has become a frequent area of ​​traffic accidents. Poor safety awareness and frequent traffic accidents have further caused traffic congestion in the surrounding areas and brought greater chain problems to all aspects. The traffic management level of subway construction needs to be improved urgently

[0005] Obviously, the vehicle traffic environment in the subway construction area is complex, and there are many factors affecting the traffic efficiency and safety around the subway construction area, so the speed control method is quite different from the management method on the general road section.

The existing traffic management methods in subway construction areas are mainly composed of fixed facilities such as speed limit signs and safety warning signs. Improve traffic efficiency, but cannot guarantee traffic safety
