Problems solved by technology

[0002] Although there are many researches and explorations related to road guidance information in China, there is no research on the design method of roadside guidance information from the perspective of micro driving behavior and lane changing behavior, which affects the implementation effect of road guidance information.
[0003] There are a large number of weaving and lane changing behaviors in the weaving area upstream of the exit ramp. Improper lane changing will lead to congestion and safety accidents. If there is no scientific and reasonable induction control management, it will become the weakest link in the entire expressway system. Therefore, reasonable and effective Setting up roadside guide information signs is the basis for the smooth operation of the weaving area upstream of the exit ramp

Embodiment Construction

[0046] The present invention is based on the driving simulation experiment platform for the optimization design method of the roadside guidance information on the upstream side of the exit ramp of the expressway. Among them, the scheme with the best overall operation effect is the optimal design scheme, which can realize the precision of traffic design and improve the traffic operation quality of expressways.

[0047] The method consists of three main steps,

[0048] One is to select the traffic flow operation characteristic index, and control the error between the experimental acquisition and the actual acquisition index, so as to ensure the feasibility of the driving simulation experiment;

[0049] The second is to establish an experimental program on this basis and collect various parameters;

[0050] The third is to consider the operation effect of roadside guidance information from two aspects of traffic efficiency and safety, and obtain the optimal solution.

Abstract

The invention provides an expressway exit ramp upstream road side road directing information optimization design method based on a driving simulation experiment platform. The method comprises steps of based on summarization of research statuses and results at home and abroad, organically integrating real measurement data and driving simulation; carrying out analysis on effects on traffic operation in expressway intercrossed regions imposed by road side directing information; verifying the feasibility of a driving simulator through two indexes of a lane change position and a lane change insertion gap which can be acquired in the real measurement data and the driving simulation experiment; on this basis, constructing a traffic flow micro behavior experiment platform to acquire related parameter indexes which are hard to acquire in the real measurement data; using the experiment platform to analyze effects on passing efficiency and safety in the intercrossed regions imposed by the design of the road side directing information; and finally providing the expressway exit ramp upstream road side road directing information optimization design method.

Description

technical field [0001] The invention relates to traffic design and traffic control management research based on driving simulation experiments. Background technique [0002] Although there are many researches and explorations related to road guidance information in China, there is no research on the design method of roadside guidance information from the perspective of microscopic driving behavior and lane changing behavior, which affects the implementation effect of road guidance information. [0003] There are a large number of weaving and lane changing behaviors in the weaving area upstream of the exit ramp. Improper lane changing will lead to congestion and safety accidents. If there is no scientific and reasonable induction control management, it will become the weakest link in the entire expressway system. Therefore, reasonable and effective Setting up roadside guidance information signs is the basis for the smooth operation of the weaving area upstream of the off-ramp...
