【摘要】:隨著全球環(huán)境問題、能源問題的日益突出,,如何建設(shè)可持續(xù)、低污染的公路將是未來交通發(fā)展的非常重要的研究課題。本文將選取公路設(shè)計因素中的車道寬度和車道功能劃分(左轉(zhuǎn)車道、右轉(zhuǎn)車道),通過交通尾氣排放模型的建立和交通仿真模型的應(yīng)用,來定量研究這些因素對交通運行和交通尾氣排放的影響。首先通過車載檢測設(shè)備OBEAS-3000進(jìn)行實地的交通尾氣排放采集;之后,基于實際的交通尾氣排放采集成果,引入比功率VSP(Vehicle Specific Power)的概念,將車輛的速度、加速度和車重與CO、HC和NOX三種氣體的尾氣排放量聯(lián)系起來,對輕型車和重型車分別建立基于VSP的排放計算模型;然后,結(jié)合交通仿真軟件VISSIM與基于VSP的排放模型,對車道寬度和車道功能劃分(左轉(zhuǎn)車道、右轉(zhuǎn)車道)分別進(jìn)行場景設(shè)計和對比分析,研究其與CO、HC和NOX三種尾氣排放之間的關(guān)系;最后,在山西省太原市選取一個典型交叉口及其相應(yīng)的路段,進(jìn)行實例分析,驗證研究結(jié)論的正確性與實踐意義;谘芯拷Y(jié)果,提出應(yīng)用于公路優(yōu)化設(shè)計的減排建議,對車道寬度給出建議取值,指出合理的渠化設(shè)計對保障通行能力和交通減排的重要性,并強調(diào)給左轉(zhuǎn)車道設(shè)計左轉(zhuǎn)專用信號相位或停車線提前的必要性等。
[Abstract]:With the problems of global environment and energy problem, how to build a sustainable and low-pollution road will be a very important research topic for future traffic development. In this paper, the influence of these factors on the traffic operation and the emission of the traffic off-gas will be quantitatively studied by selecting the lane width and the lane function division (left-turn lane and right-turning lane) in the road design factors. Firstly, the vehicle-mounted detection equipment OBEAS-3000 is used for carrying out the field-based traffic tail gas emission collection, and then, based on the actual traffic tail gas emission acquisition result, the concept of the specific power VSP (Vehicle Specific Power) is introduced, and the speed, the acceleration and the vehicle weight of the vehicle are compared with the CO, and then, combining the traffic simulation software VISSIM and the VSP-based emission model, dividing the lane width and the lane function (left turn lane, The relationship between the three kinds of tail gas emissions from CO, HC and NOX is studied by scene design and contrast analysis respectively. At last, a typical intersection and its corresponding road section are selected in Taiyuan city of Shanxi Province, and an example analysis is carried out to verify the correctness and practical significance of the research conclusion. Based on the results of the study, the paper puts forward the suggestion of the emission reduction applied to the road optimization design, gives the recommended value to the width of the lane, and points out the importance of reasonable canalization design to the guarantee of traffic capacity and traffic emission reduction. And emphasize the need to design a left-turn dedicated signal phase or a stop line in advance for a left-turn lane.
