发布时间：2019-04-11 09:33
【摘要】：随着全球环境问题、能源问题的日益突出，，如何建设可持续、低污染的公路将是未来交通发展的非常重要的研究课题。本文将选取公路设计因素中的车道宽度和车道功能划分（左转车道、右转车道），通过交通尾气排放模型的建立和交通仿真模型的应用，来定量研究这些因素对交通运行和交通尾气排放的影响。首先通过车载检测设备OBEAS-3000进行实地的交通尾气排放采集；之后，基于实际的交通尾气排放采集成果，引入比功率VSP（Vehicle Specific Power）的概念，将车辆的速度、加速度和车重与CO、HC和NOX三种气体的尾气排放量联系起来，对轻型车和重型车分别建立基于VSP的排放计算模型；然后，结合交通仿真软件VISSIM与基于VSP的排放模型，对车道宽度和车道功能划分（左转车道、右转车道）分别进行场景设计和对比分析，研究其与CO、HC和NOX三种尾气排放之间的关系；最后，在山西省太原市选取一个典型交叉口及其相应的路段，进行实例分析，验证研究结论的正确性与实践意义。基于研究结果，提出应用于公路优化设计的减排建议，对车道宽度给出建议取值，指出合理的渠化设计对保障通行能力和交通减排的重要性，并强调给左转车道设计左转专用信号相位或停车线提前的必要性等。
[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.
