Embodiment Construction

[0083] Embodiments will be described in detail below with reference to the accompanying drawings.

[0084] Such as figure 1 with 2 As shown, a stepwise variable speed limit control method for expressway maintenance work areas is characterized in that it includes the following steps:

[0085] Step 1: Set the traffic flow detector and the roadside variable information board. The specific setting method is as follows:

[0086] Delineate warning zone 1 and transition zone 2 according to the provisions of "Highway Maintenance Safety Operation Regulations";

[0087] Set the traffic flow detector at the beginning of the warning zone 1 to 5, set the traffic flow detector to 6 at the junction of the warning zone 1 and the transition zone 2, and set the traffic flow detector to 7 at the end of the transition zone 2;

[0088] The above groups of traffic flow detectors detect data every 5 minutes, and transmit the traffic flow data to the control center; these data include traffic flow...

Abstract

The invention proposes a stepped variable speed-limitation control method of an expressway maintenance operation region. The stepped variable speed-limitation control method comprises the steps of setting traffic flow detectors at a warning region and a transition region of the expressway maintenance operation region; acquiring traffic running parameters of the warning region and the transition region o the expressway maintenance operation region in real time; judging whether each road segment of the expressway maintenance operation region is congested or not; calculating variable speed-limitation values of the warning region and the transition region; and displaying a speed-limitation value of a current road segment in real time by a road side speed-limitation information prompt plate, and achieving dynamic driving speed control of the expressway maintenance operation region. According to the stepped variable speed-limitation control method proposed by the invention, the phenomenon ofcongestion of the expression maintenance operation region is reduced, and the passing efficiency and the driving safety are improved.

Description

technical field [0001] The invention relates to a speed limit control method, in particular to a step-type variable speed limit control method in an expressway maintenance operation area, belonging to the fields of traffic safety and dynamic traffic control. Background technique [0002] With the continuous and rapid development of my country's economy and society, the traffic volume of expressways has increased rapidly, and the expressways built in the early stage in my country have entered the stages of maintenance, major and medium repairs, and reconstruction and expansion. Some lanes need to be closed during expressway maintenance work, and vehicles need to slow down in advance to ensure that they can pass through the maintenance work area safely and quickly. [0003] Most of the existing speed limit methods adopt a fixed value. When the traffic flow is large, traffic congestion is likely to occur in the warning area and the upstream transition area, or the road utilizat...
