【摘要】：車速離散作為“人-車-道路-環(huán)境”共同作用下車速的總體表現(xiàn),是影響交通安全的重要因素之一。本文主要研究混合交通環(huán)境下公路的車速離散現(xiàn)象,而干線公路城鎮(zhèn)段是典型的混合交通環(huán)境,兼有干線公路功能及城鎮(zhèn)道路功能的雙重特征,道路行車環(huán)境更為復(fù)雜。因此,對于以干線公路城鎮(zhèn)段為典型代表的混合交通環(huán)境,車速離散現(xiàn)象尤為突出,其車速離散的演化機理問題異常復(fù)雜,需要特別的關(guān)注。本文結(jié)合我國道路混合交通環(huán)境的基本特點,研究混合交通環(huán)境下基于路段的車速離散程度的描述方法；對干線公路城鎮(zhèn)段進(jìn)行分類,明確本文重點研究對象；探索無人機航拍的調(diào)查方法,以獲得車輛在較長路段上的速度波動,便于探究路段的車速離散影響因素；從道路條件、交通條件、橫向干擾等方面探尋不同條件下的車速離散的基本特征與規(guī)律；基于因子分析方法,探索混合交通環(huán)境下高維度影響因素與車速離散的內(nèi)在聯(lián)系；運用多元線性回歸模型,構(gòu)建多層次的車速離散性致因?qū)哟谓Y(jié)構(gòu)模型�；谲囁匐x散性致因?qū)哟谓Y(jié)構(gòu)模型,提出降低車速離散性、提高干線公路城鎮(zhèn)段安全性的對策。本文為系統(tǒng)認(rèn)識混合交通環(huán)境下車速離散的形成及時空演化機理提供新方法,是進(jìn)一步研究車速離散性與交通安全的關(guān)系的理論基礎(chǔ),為道路交通管理部門科學(xué)制定交通管控措施提供理論依據(jù)。
[Abstract]:Speed dispersion is one of the important factors affecting traffic safety as the overall performance of speed under the joint action of "man, car, road and environment". This paper mainly studies the discrete phenomenon of highway speed in mixed traffic environment, and the urban section of trunk highway is a typical mixed traffic environment, which has the dual characteristics of both the function of trunk road and the function of urban road, so the driving environment of road is more complex. Therefore, for the mixed traffic environment represented by the urban section of the trunk highway, the phenomenon of speed dispersion is particularly prominent, and the evolution mechanism of the speed dispersion is extremely complex and needs special attention. According to the basic characteristics of the mixed traffic environment of our country, this paper studies the description method of the speed dispersion degree based on the road section in the mixed traffic environment, classifies the urban section of the trunk highway, and clarifies the research object of this paper. The investigation method of UAV aerial photograph is explored in order to obtain the speed fluctuation of the vehicle on the longer road section, and it is convenient to explore the discrete influence factors of the speed of the road. This paper explores the basic characteristics and rules of vehicle speed discretization under different conditions from road condition, traffic condition and lateral interference, and explores the internal relationship between high dimensional influence factors and speed dispersion in mixed traffic environment based on factor analysis method. The multivariate linear regression model is used to construct a multilevel hierarchical model of speed discreteness. Based on the hierarchical structure model of vehicle speed discretization, this paper puts forward some countermeasures to reduce the speed dispersion and improve the safety of the urban section of the trunk highway. This paper provides a new method for the systematic understanding of the formation and space-time evolution mechanism of vehicle speed discretization in mixed traffic environment, which is the theoretical basis for further studying the relationship between speed discreteness and traffic safety. It provides theoretical basis for road traffic management department to make traffic control measures scientifically.
