Problems solved by technology

In the early 21st century, many cities met the needs of urban motor vehicle travel through large-scale construction and widening of roads, but this not only failed to meet the needs of motor vehicle travel for a long time, but also stimulated the growth of car ownership and the incidence of traffic accidents to a certain extent. occur
However, at this stage, there is a lack of research at the micro level under special conditions, such as analyzing the impact of the installation of road speedometers on the driver's reaction behavior under rainy conditions

Embodiment Construction

[0023] Such as figure 1 As shown, a method for evaluating the influence of road speedometers on driver's reaction behavior under rainy conditions includes the following steps:

[0024] (1) Selection of the initial reference road section and the collection of related covariate data: by querying relevant literature, it can be seen that the appropriate interval for the sample ratio of the initial reference road section and the experimental road section is 1:1.5 to 1:30; The ratio is 1:10. After determining the proportion of the initial reference road section, collect relevant covariate data, which are the total population N (unit: person) of the administrative area where the road section is located, the economic development GDP (unit: 100 million yuan) of the administrative area where the road section is located, and the road grade M i , road width L (unit: meter), road friction coefficient f, road isolation condition K (record 1 if it is hard isolation, and 0 if it is soft isol...

Abstract

The invention discloses a method for evaluating the influence of a road speedometer on the driver's reaction behavior under rainy conditions, comprising the following steps: (1) selecting an initial reference road section and collecting relevant covariate data; (2) selecting a scoring model and parameters (3) Determination of the final reference road section; (4) Collecting the driver's reaction behavior data of the experimental road section and the reference road section; (5) Judging the impact effect. The present invention can reduce the influence of other covariates to a certain extent, and finally attribute the driver's reaction behavior change to the only influencing factor "speedometer under rainy weather conditions".

Description

technical field [0001] The invention relates to the technical field of the driver's reaction behavior, in particular to a method for evaluating the influence of a road speedometer on the driver's reaction behavior under rainy conditions. Background technique [0002] With the rapid development of social economy, urban infrastructure construction and traffic volume have also grown rapidly. In the early 21st century, many cities met the needs of urban motor vehicle travel through large-scale construction and widening of roads, but this not only failed to meet the needs of motor vehicle travel for a long time, but also stimulated the growth of car ownership and the incidence of traffic accidents to a certain extent. occur. At the same time, road safety has also become the focus of social attention. Under this background, road speedometers are widely used in many cities as a restrictive measure. [0003] In the field of scientific research and patent application, the impact of...
