【摘要】：随着城市快速发展,道路基础设施不断完善,城市道路作业(维护、清洁、抑尘)成为城市道路养护必可不少的工作,其不仅有助于美化道路环境,而且还有助于改善行车状况,提高行车安全。但是,由于道路作业属性决定作业车辆有其自身的行驶特点,如尽可能的保持匀速,尽量不随意变更车道以便能够高质量的完成既定作业任务。因此,研究在该特点下作业车运行对道路的影响规律,达到优化作业车运行方案,降低作业车辆对路网的影响,对于提高城市道路作业的科学性、安全性、高效性、绿色性具有重要意义。首先,本文综述了国内外城市道路作业相关研究,着重的总结梳理了国内外学者在道路作业区、道路作业影响及策略等方面的研究方法和模型,为本文的研究提供了重要的参考和启发。同时,阐述了本文研究的主要内容及技术路线。其次,依托PARAMICS仿真软件API接口和其函数库,编写作业车道路影响研究的控制程序,创建不同功能的控制插件,加载到路网模型中,实现对作业车的控制和指标评价数据的采集、处理。再者,深入的研究了作业车对路段和交叉口的影响,基于PARAMICS仿真软件,通过对路段和交叉口不同的作业环境进行仿真建模,得出作业车运行对路段和交叉口其它车辆的延误和安全性的影响情况,并分析作业车运行状态(作业车速、作业车道、交通量;绿信比、作业车速、交通量)的改变对于路段(延误和安全风险)和交叉口(延误)上其它车辆影响情况的变化规律,对作业车的运行状态与其产生影响之间的作用机理进行阐释,并以此为基础深入开展城市道路作业车运行方案优化的相关研究。最后,本文基于作业车对路段和交叉口的影响研究,应用回归分析法和线性规划模型相结合,提出了道路作业车运行方案优化模型,对作业车运行方案进行优化设计。此外,从作业车运行全路径的角度出发,建立了作业车全路径影响分析模型,对作业车运行方案优化模型的预估影响进行校核验证,最后通过对具体实例的研究,进而表明依据作业车对路段和交叉口研究的规律进行作业车运行方案优化方法的可行性,为制定科学、合理、高效、绿色的作业方案提供相应的理论和技术支持。
[Abstract]:With the rapid development of the city, road infrastructure continues to improve, urban road operation (maintenance, cleaning, dust suppression) has become a lot of urban road maintenance work, which is not only conducive to beautifying the road environment. And it also helps to improve the driving condition and improve the driving safety. However, because of the road operation attributes, the operating vehicle has its own driving characteristics, such as keeping the speed as well as possible. Try not to arbitrarily change the lane in order to be able to complete the established task of high quality. Therefore, under the characteristics of the operation vehicle operation on the road impact law, to optimize the operation plan of the vehicle. Reducing the impact of operating vehicles on the road network is of great significance for improving the scientific safety efficiency and green of urban road operation. Firstly this paper summarizes the related research of urban road operation at home and abroad. This paper summarizes and combs the research methods and models of domestic and foreign scholars in road operation area, road operation impact and strategy, which provides an important reference and inspiration for the research of this paper. The main content and technical route of this paper are expounded. Secondly, based on the PARAMICS simulation software API interface and its function library, the control program of the road impact research of the working vehicle is written. Create different functions of the control plug-in, load into the road network model, to achieve the control of the job vehicle and index evaluation data collection, processing. Furthermore, the impact of the job vehicle on road sections and intersections is deeply studied. Based on the simulation software of PARAMICS, through the simulation modeling of different working environment of road sections and intersections, the influence of the operation of job vehicles on the delay and safety of other vehicles in road sections and intersections is obtained. And analyze the operating state of the vehicle (operating speed, operation lane, traffic volume; The change of green letter ratio, operating speed, traffic volume) on the road (delay and safety risk) and intersection (delay) on other vehicles change law. On the basis of explaining the action mechanism between the operating state and the influence of the operation vehicle, and on the basis of it, the paper carries out the relevant research on the optimization of the operation plan of the urban road operation vehicle. Finally. Based on the research of the influence of the job vehicle on the road section and the intersection, this paper puts forward the optimized model of the operation plan of the road work vehicle by combining the regression analysis method with the linear programming model. In addition, from the point of view of the full path of the operation vehicle, the analysis model of the overall path impact of the operation vehicle is established. Check and verify the prediction effect of the optimization model of the operation plan, and finally through the study of specific examples. Then it shows the feasibility of optimizing the operation plan of the working vehicle according to the law of the research on the road section and the intersection, so as to make the scientific, reasonable and efficient operation plan. The green operation plan provides the corresponding theory and technical support.
