【摘要】：G201林口至向阳段是林口县域内“二纵一横”骨架公路网中的纵线之一。近年来林口县社会经济综合实力不断提升,刺激了县域内交通运输需求的快速增长,公路交通量已经翻倍。但因现有骨架公路网道路等级普遍偏低、通行能力小等问题,导致区域内道路交通堵塞时有发生,已成为制约林口县社会经济可持续发展的瓶颈,且交通安全隐患极大。因此,G201林口至向阳段改扩建工程对满足区域内快速增长的交通需求、保障林口县经济可持续发展具有重要意义。分析了G201林口至向阳段改扩建工程影响区内社会经济及综合交通运输系统发展现状,并对其发展趋势进行了预测,论证了G201林口至向阳段在区域路网中的地位和作用。基于交通量调查数据,分析得到了影响区内现状交通特征,综合考虑社会经济发展需求,采用直接法和弹性系数法预测得到了G201林口至向阳段未来特征年的交通量。依据交通量预测结果,考虑当地地形地质条件及城镇规划等影响因素,拟定了G201林口至向阳段改扩建工程的技术标准,论证并提出了G201林口至向阳段改扩建工程的起终点和路线方案,并对其交叉工程、交通工程及沿线设施等进行了设计。从节能、土地利用、社会、环境、经济等方面对G201林口至向阳段改扩建工程路线方案进行了综合评价,针对各种可能存在的不利影响,提出了相应的改善措施。综合评价结果表明,G201林口至向阳段改扩建工程的开展具备可行性。
[Abstract]:G201 section from Linkou to Xiangyang is one of the vertical lines in the "two vertical and one horizontal" skeleton highway network in Linkou county. In recent years, the comprehensive social and economic strength of Linkou County has been continuously improved, which has stimulated the rapid growth of transportation demand in the county area, and the road traffic volume has doubled. However, due to the problems of low road grade and low traffic capacity in the existing skeleton highway network, traffic jams occur from time to time in the region, which has become the bottleneck restricting the sustainable development of social economy in Linkou County, and the hidden danger of traffic safety is very great. Therefore, the reconstruction and extension project of G201 Linkou to Xiangyang section is of great significance to meet the rapid growth of traffic demand in the region and to ensure the sustainable economic development of Linkou County. This paper analyzes on the development status of social economy and comprehensive transportation system in the affected area of the reconstruction and extension project from G201 Linkou to Xiangyang section, forecasts its development trend, and demonstrates the position and function of G201 Linkou to Xiangyang section in the regional road network. Based on the traffic volume survey data, the present traffic characteristics of the affected area are analyzed and the traffic volume in the future characteristic year of G201 Linkou to Xiangyang section is predicted by direct method and elastic coefficient method considering the demand of social and economic development. According to the result of traffic volume prediction, taking into account the local topographic and geological conditions and town planning, the technical standard for the reconstruction and extension project of G201 section from Linkou to Xiangyang is drawn up. The starting end point and route scheme of the reconstruction and extension project of G201 Linkou to Xiangyang section are presented, and the cross engineering, traffic engineering and facilities along the line are designed. From the aspects of energy saving, land use, society, environment, economy and so on, this paper makes a comprehensive evaluation on the route scheme of the reconstruction and extension project of G201 Linkou to Xiangyang section, and puts forward corresponding improvement measures in view of various possible adverse effects. The comprehensive evaluation results show that the extension project of G201 Linkou to Xiangyang section is feasible.
