【摘要】：道路線形是能夠保證車輛安全行駛的一個(gè)重要影響因素，其優(yōu)劣決定著道路安全狀況。所以在盡可能消除各種安全隱患的同時(shí)，必須在高速公路設(shè)計(jì)階段設(shè)計(jì)較好的道路線性。目前我國(guó)道路線性設(shè)計(jì)方法主要以設(shè)計(jì)速度法為主，這種方法是以固定的設(shè)計(jì)速度進(jìn)行道路線性設(shè)計(jì)，車輛在實(shí)際行駛過程中無法保持固定不變的車速，因此具有很大的極限性。 本文以我國(guó)不同類型高速公路及運(yùn)行車輛作為研究對(duì)象，采取了將運(yùn)行速度作為設(shè)計(jì)指標(biāo)進(jìn)行高速公路不同路段的速度預(yù)測(cè)模型的同時(shí)還考慮了駕駛員的需求以及駕駛員的駕駛規(guī)律和道路交通環(huán)境，根據(jù)車輛在實(shí)際中的運(yùn)行規(guī)律進(jìn)行道路線形設(shè)計(jì)。對(duì)國(guó)內(nèi)外道路線形和運(yùn)行速度的研究狀況進(jìn)行了完整的分析之后，論文從道路線性的角度對(duì)高速公路運(yùn)行車速變化規(guī)律進(jìn)行了分析，并沒有車輛差異和相互干擾等情況，僅僅考慮了在車輛行駛過程中道路線性對(duì)駕駛員判斷所產(chǎn)生的影響，體現(xiàn)在車輛的運(yùn)行速度上。而運(yùn)行速度法的核心是在行車速度預(yù)測(cè)模型上。那么在對(duì)國(guó)內(nèi)外運(yùn)行車速和道路線性的狀況進(jìn)行分析后，本文最終提出了基于道路線形來預(yù)測(cè)高速公路運(yùn)行車速的方法，分析了道路線形與運(yùn)行車速的相互關(guān)系，從而進(jìn)一步得到各類線形路段高速公路運(yùn)行車速的變化規(guī)律，，并且在該基礎(chǔ)上應(yīng)用線性回歸法構(gòu)建基于道路線形的高速公路預(yù)測(cè)模型。根據(jù)所得到的模型，提出了線性條件下的速度控制方法。最后，依托已建成的依保高速公路，對(duì)高速公路行車速度預(yù)測(cè)模型進(jìn)行了實(shí)例分析，取得了成果，并驗(yàn)證了科學(xué)性與真實(shí)性。
[Abstract]:Road alignment is an important factor to ensure the safety of vehicles, which determines the road safety situation. Therefore, while eliminating all kinds of hidden dangers as far as possible, better road linearity must be designed in the design stage of freeway. At present, the main method of road linear design in our country is the design speed method. This method is to design the road linearly at a fixed design speed, and the vehicle can not keep the constant speed in the actual driving process. Therefore, it has a great limit. In this paper, different types of highways and running vehicles in China are taken as the research object. Taking the running speed as the design index to carry out the speed prediction model of different sections of expressway, the author also takes into account the needs of the driver, the driving law of the driver and the road traffic environment. The road alignment design is carried out according to the running rule of the vehicle in practice. After a complete analysis of the research status of road alignment and running speed at home and abroad, the paper analyzes the changing law of expressway speed from the angle of road linearity, and there are no vehicle differences and interferences. The influence of road linearity on driver's judgment is considered only in the course of vehicle driving, which is reflected in the running speed of vehicle. The core of the running speed method is the speed prediction model. Then, after analyzing the running speed and road linearity at home and abroad, this paper finally puts forward a method to predict the running speed of expressway based on the road alignment, and analyzes the relationship between the road alignment and the running speed. Furthermore, the changing law of the speed of highway running on all kinds of linear sections is obtained, and on this basis, the prediction model of expressway based on road alignment is constructed by using linear regression method. According to the obtained model, a speed control method under linear conditions is proposed. Finally, based on the established Yibao Expressway, an example analysis of the expressway speed prediction model is carried out, and the results are obtained, and the scientificity and authenticity of the model are verified.
