【摘要】：我国高速公路的发展初期大部分的建设投资成本很高,主要是对高速公路通行能力的分析不够准确而造成的。与此同时,高速公路收费站配置的不合理,通行能力预期估计过高,造成在车辆流动量高峰时段出现交通拥堵,从而对高速公路的安全和运输效率产生了较大的影响。此外,我国人们在网上购物的人数增多使得物流事业发展迅速,近几年私人拥有汽车的数量高速增加明显体现了人们生活质量的提升,国家节假日客车免费的政策出台,这些都造成了高速公路的车辆承载量接近于饱和。现状车流量完全超出高速公路设计规划的通行能力。因此,探索研究高速公路的通行能力,合理的规划完善高速公路的路网建设是当前研究的重点。目前和未来一个时期内,项目影响区的社会经济将处于高速发展的阶段,唐津高速公路的交通量仍将保持较高的增长速度。随着沿线区域城镇化水平的提高,城镇人口会不断增加,必然导致区域出行总次数的增加,区域交通线上的交通量也将随之上升;沿线区域除中心城市规模不断扩大以外,中小城镇的城市化水平提高速度也很快,城镇化水平的提高带来交通量的增长。交通需求大量增加完全是由区域迅速发展的机器自动化以及国家汽车产业和消费政策的影响而造成的,而人们日渐多样化的出行目的和需求更高的交通服务,也更高的要求区域交通的各项指标,目前唐津高速公路已接近饱和的通行状况、通行条件已不能适应未来的交通发展。本文定量的对通行能力这一问题进行分析,采用理论与实践相结合的方式,进行深入的探讨和研究。首先概述高速公路通行能力的基本理论,接着分析高速公路通行能力的影响因素及修正系数,并系统的分析介绍高速公路服务水平,然后根据实际测量的唐津高速的交通量,运用本文介绍的理论知识对唐津高速公路进行了实际的通行能力的分析,最后对唐津高速公路远景的交通量进行预测,通过对唐津高速公路的通行能力分析来对整个高速公路路网规划进行分析。
[Abstract]:At the beginning of the development of expressway in our country, most of the construction investment cost is very high, which is mainly caused by the inaccurate analysis of the expressway traffic capacity. At the same time, the allocation of toll stations on the highway is unreasonable. The expected capacity is overestimated, resulting in traffic congestion during the peak period of vehicle flow, which has a greater impact on the safety and transport efficiency of the highway. The increase in the number of people shopping on the Internet in China makes the development of logistics rapidly. In recent years, the number of privately owned cars has increased rapidly, which obviously reflects the improvement of people's quality of life. The national holiday bus free policy was issued, which resulted in the freeway vehicle carrying capacity approaching saturation. The current traffic volume is completely beyond the capacity of highway design planning. Therefore. It is the focus of current research to explore and study the capacity of freeway, and to plan and perfect the highway network construction reasonably. At present and in a period of time in the future. The social economy of the area affected by the project will be in the stage of rapid development, and the traffic volume of the Tangjin Expressway will still maintain a relatively high growth speed. With the improvement of urbanization level along the area along the road, the urban population will continue to increase. It will inevitably lead to the increase of the total number of regional trips, and the traffic volume on the regional traffic lines will also rise with it. In addition to the continuous expansion of the scale of central cities along the road, the level of urbanization of small and medium-sized towns is also increasing rapidly. The increase of the level of urbanization leads to the growth of traffic volume. The increase of traffic demand is caused by the rapid development of regional machine automation and the impact of national automobile industry and consumption policies. And people increasingly diversification of travel purposes and higher demand for transport services, but also higher requirements for regional traffic indicators, the current Tangjin Expressway is close to saturated traffic conditions. Traffic conditions can no longer adapt to the future traffic development. This paper quantitatively analyzes the problem of capacity, using the combination of theory and practice. Firstly, it summarizes the basic theory of freeway capacity, then analyzes the influence factors and correction coefficient of expressway traffic capacity, and systematically analyzes and introduces the expressway service level. Then according to the actual traffic volume of Tangjin Expressway, using the theoretical knowledge introduced in this paper, the actual traffic capacity of Tang-Jin Expressway is analyzed, and the traffic volume of Tang-Jin Expressway is forecasted. Through the analysis of the capacity of Tangjin Expressway, the whole highway network planning is analyzed.
