Method for controlling traffic signals under bi-direction and two-lane road maintenance construction situation

Abstract

The invention discloses a method for controlling traffic signals under the bi-direction and two-lane road maintenance construction situation. The method comprises the steps of traffic data collecting, whole-red phase duration calculating, period duration calculating, passing phase duration calculating and traffic signal controlling scheme implementing. According to the method, the traffic circulation character under the bi-direction and two-lane road maintenance construction situation is fully taken into consideration, and a signal control scheme is designed according to the bi-direction and two-lane road maintenance construction needs. A most common four-phase signal control scheme is adopted to give wayleave to bi-direction vehicles in sequence according to the signal control method of a city intersection. The method is very suitable for long-time bi-direction and two-lane road maintenance construction, convenient to calculate and actually operate, high in practicality and capable of improving the overall running efficiency of a traffic system under the bi-direction and two-lane road maintenance construction situation, and has very important practical significance.

Description

technical field [0001] The invention relates to road construction traffic organization and signal control optimization technology, in particular to a traffic signal control method in a two-way two-lane road maintenance construction area. Background technique [0002] At this stage, our country is in the period of comprehensive construction of transportation infrastructure, and the planning, new construction, reconstruction and expansion projects of various grades of roads are being carried out all over the country. Taking expressways as an example, in 2013, the national expressway construction completed an investment of 729.776 billion yuan. It can be seen that my country's current investment in road construction is still very large. In the future, as the pace of road construction slows down and the road network gradually takes shape, engineering projects related to roads and bridges will shift from focusing on construction at present to centering on maintenance. The data ...

Problems solved by technology

[0005] After research by the inventors, it was found that during the maintenance and construction of two-way and two-lane roads, although the above-mentioned flag-bearer control method is widely used at home and abroad, this method is not optimal: 1) Although the flag-bearer will go through the system training, but for some actual situations, this control method is carried out on the spot by each flag bearer based on their own experience and understanding

This will inevitably lead to certain flaws in the actual control effect, and cannot minimize the impact on traffic

2) When the maintenance and construction of the road is a time-consuming project such as overhaul, this kind of manual control is very labor-intensive, and it is difficult to continue for a long time
