Embodiment 1
Using certain domestic two-lane highway of Shaanxi Province as evaluation object, the highway annual average daily traffic is less than the present embodiment
6000pcu/d, whole day are substantially in freestream conditionses, meet and assess section selection requirement.System-wide section is to transport the medium-sized of goods
Based on lorry, Shaanxi domestic K1073-K1100 system-wides section desin speed 40km/h, Δ ν≤20km/h, meet that rate uniformity will
Ask such as table 1, road environment is preferable, the 9m that has a lot of social connections, curb-to-curb width 7m, is the abundant two-lane highway of road geometry linear.
The rate uniformity evaluation criterion table of table 1
Because designer's machinery applies mechanically standard, specification index, occur it is linear it is discontinuous, velocity variations are excessive, exceed
Driver psychology bears the limit and accident " stain " section of more serious traffic safety hidden danger be present --- and-the section is exactly typical case
A section.
The traffic accident of national highway generation over the past two years of the domestic K1073-K1087 sections in Shaanxi is a lot of.Accident is mainly because under
Caused by speed too fast driver's heart physiological strains reaction in slope is too late, driver's heart physiological strains judges operational error.
GPS detections real-time speed, portable pendulum tester measure pavement friction factor are adopted in the present embodiment, and selects local highway operation
Main force's vehicle, loading capacity 8t east wind light truck, male driver 13, the data in the section are carried out according to the structural environment of model
Measurement, brings measurement data into present system mode, it is as shown in table 2 to obtain result.
Certain the two-lane highway accident changes in heart rate table of table 2
Two-lane highway Traffic safety evaluation method of the present invention based on driver comfort with《Mountain based on Driver's Factors
Area's Key Parameter of Two-Lane research》Contrast of the collaboration mode mentioned to traffic accident safety evaluation result, with inner
Journey is abscissa, and the traffic factor for draw the actual traffic accident number in the mileage respectively, obtaining using the inventive method stimulates
The traffic factor that model obtains is carried in function (%) and document stimulates function (%) (referred to herein as former traffic factor stimulation letter
Number) changing trend diagram, as shown in figure 1,
From figure 1 it appears that the traffic factor being calculated using the present invention stimulates function all more than 30%, and with
Accident number increases, and traffic factor stimulates function also accordingly to increase, and trend is consistent substantially, and more former traffic factor stimulates function
It is higher with accident number trend matching degree, it is seen that the evaluation model accuracy is higher.
The model can be used for the examination for being established based on the accident prone location of Driver's Factors, with reference to actual landform situation energy
It is proposed to make up improvement using flexible design or safety devices in advance, can investment reduction;This evaluation method is simply easily operated, uses
This model can reduce the generation of road accident, improve the comfortableness of driver's traveling, for driver's one safety and comfort of creation
Environment, a reliable method is provided for the research of traffic safety.
