【摘要】：如何更好的发挥城市快速路安全、快捷、经济和舒适的功能,成了社会各界热议的研究课题。实践证明,合理的限速对于提高城市快速路的安全、快捷、经济和舒适水平具有促进作用,相反,不适当的车速限制则会反其道而行之。目前,我国城市快速路的管理水平总体上不是很完善,限速标准的制定也缺乏一定的理论研究成果作为技术支撑。本文通过对国内外限速相关的理论研究进行深入分析,提出了基于运行速度的城市快速路合理限速。通过对限速的必要性和限速理论依据的分析,提出选择运行速度作为限速依据。在分析影响限速因素的基础上,对城市快速路交通流特性进行定性和定量分析,并给出了城市快速路的运行速度预测方法。在此基础上,结合驾驶员的视认性和心理反应特性,得到了城市快速路限速路段最小长度标准,以及如何进行限速路段的划分与限速值的确定,同时分析论证了一些常见限速措施,并通过VISSIM进行了仿真验证,验证了其有效性和合理性。本文提出的城市快速路合理限速值及限速路段最小长度值,为城市快速路建设、管理部门设置限速提供了合理、科学的理论依据及指导。
[Abstract]:How to better play the safe, fast, economic and comfortable functions of urban expressway has become a hot research topic. It is proved by practice that reasonable speed limit can promote the safety, speed, economy and comfort level of urban expressway. On the contrary, inappropriate speed limit will reverse the speed limit. At present, the management level of urban expressway in China is not perfect, and the formulation of speed limit standard is lack of theoretical research results as technical support. Based on the theoretical analysis of speed limit at home and abroad, this paper puts forward a reasonable speed limit for urban expressway based on running speed. Based on the analysis of the necessity of speed limit and the theoretical basis of speed limit, it is put forward that the speed of operation should be chosen as the basis of speed limit. Based on the analysis of the factors affecting the speed limit, the traffic flow characteristics of urban expressway are analyzed qualitatively and quantitatively, and the method of speed prediction for urban expressway is given. On this basis, combined with the drivers' visual recognition and psychological reaction characteristics, the minimum length standard of the speed limit section of the urban expressway is obtained, and how to divide the speed limit section and determine the speed limit value are obtained. At the same time, some common speed limiting measures are analyzed and demonstrated, and the validity and rationality of these measures are verified by Visual IM simulation. The reasonable speed limit and the minimum length of the speed limit section proposed in this paper provide reasonable and scientific theoretical basis and guidance for the construction of urban expressway and the setting of speed limit by the management department.
