Problems solved by technology

However, due to the large differences in the quality and power performance of various vehicles, the speeds of vehicles with different performance and loads are quite different when they go uphill continuously. In addition, some drivers have poor traffic safety awareness, which leads to frequent replacement of some vehicles. The phenomenon of overtaking on the road has brought great safety hazards

Embodiment Construction

[0044] The technical solution of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0045] A kind of one-way two-lane uphill section of the present invention variable speed limit method, comprises the following steps,

[0046] S1: Set the maximum range of speed limits for the left and right lanes of the one-way, two-lane uphill section according to the road grade and road characteristics, and use the first fixed information prompt to give a reminder before the one-way, two-lane uphill section;

[0047] S2: Use the traffic parameter automatic detection equipment to calculate the average speed V of the traffic flow on the left lane respectively L and the average speed V of traffic in the right lane R ;

[0048] S3: The V obtained in step S2 L and V R Compare with the maximum range of speed limit values ​​of the left and right lanes in step S1 to obtain the real-time speed limit ranges of the left and right lanes, and sim...

Abstract

The invention relates to a unidirectional dual-lane uphill section lane-separation variable speed-limiting method. According to the method, lane-separation speed limiting is performed according to characteristics of different lanes, a limited speed value of a fast lane (ie, the left lane) can be set by taking basic information such as an average vehicle speed and characteristics of the fast lane as a real-time setting basis, and a limited speed value of a slow lane (ie, the right lane) is dynamically adjusted according to an average vehicle speed and characteristics of the slow lane. The unidirectional dual-lane uphill section lane-separation variable speed-limiting method can reduce mutual interference between a fast vehicle and a slow vehicle, can solve the problem of different vehicle speeds of different vehicles on an uphill section, can increase passing efficiency of the lanes if drivers can drive according to lane-separation limited speeds, can eliminate traffic conflicts caused by different vehicle speeds, further reduces accident rate, and improves traffic safety level of the uphill section.

Description

technical field [0001] The invention relates to the field of highway traffic management, in particular to a lane-splitting variable speed limit method for a one-way two-lane uphill section. Background technique [0002] At present, the traffic management measures for the uphill section of the one-way two-lane road are almost blank, and drivers basically drive according to their own habits. Individual accident-prone road sections only remind drivers to drive carefully in accordance with relevant traffic regulations, and these measures have not attracted enough attention from the majority of drivers. However, due to the large differences in the quality and power performance of various vehicles, the speeds of vehicles with different performance and loads are quite different when they go uphill continuously. In addition, some drivers have poor traffic safety awareness, which leads to frequent replacement of some vehicles. The phenomenon of overtaking on the road has brought gre...
