【摘要】 近年来,我国经济实力的提升和交通量的剧增造成了现在很多高速公路不能满足现有交通需求等现象。为了改善这一拥挤的交通状况，高速公路扩建已成为我国公路工程建设中缓解交通压力的一种主要方式。但是对于扩建工程来说,目前我们对其交通组织方案的探讨还显得很浅薄。如果选取了不合理的交通组织方案，那将产生许多不利的影响，像交通拥堵、延误出行时间、资源乱费等影响。不合理的交通组织方案不仅会造成经济损失和环境污染，同时还会给社会带来不利影响。在高速公路扩建期间，交通组织是一项非常重要的工作，它涵盖了施工组织、经济发展以及交通运营与管理等多个方面。交通组织质量的好坏直接关系到高速公路扩建施工进度的快慢与质量的高低，因此它既是一个相当难解决的问题，同时也是一个亟待解决的问题。因此，本文所研究内容有助于交通组织问题的解决。本文以高速公路扩建工作区交通组织优化研究的相关文献为基础，以高速公路扩建期工作区交通流为研究对象，开展优化研究，兼顾系统分析的方法，在分析高速公路扩建工作区基于驾驶员信息处理能力和交通组织影响因素的基础上，参考现有一般高速公路扩建工作区交通组织方案，提出了一套实际可行的交通组织方案,实现了高速公路扩建期工作区交通组织方案合理、可行和利益兼顾的目的。更多还原

【Abstract】 In recent years,with the development of economy and the traffic volume on highway in our country,many highways built up in recent years appear that the capacity isinsufficient and service level drop.It has become the most important reason for thetraffic jam.For improving these conditions,Expressway Expanding Construction is afeasible way to ease the traffic pressure in highway projects in our country.But now,The reasearch on traffic organization is not enough in China.If the traffic organizationis not reasonable,some possive situation will appear such as traffic jam,transportation delays and resourcewasting.It is not only caused sever economic lossand environmental pollution,but also brought a lot of negative effects to the societyand people.Traffic organization is a very important job in Expressway ExpandingConstruction.It involves the social ecnomic development,the construction organizationand traffic operation management,etc.The effectiveness of the traffic organization hasa direct effect on the construction quality and schedule.It is not only difficultproblem,but also a problem to be resolved instantly.So,It is meaningful to study onoptimization of traffic organization in work zone of Expressway ExpandingConstruction.Based on the literature on the optimization of traffic organization in work zone ofExpressway Expanding Construction,The thesis studies on the traffic flow in thesystem analysis method.After analysis on the capacity of the driver informationprocessing and the factors of the traffic organization,reference on the existing trafficorganization,The thesis has proposed a feasible traffic organization plan.It hasrealized that the traffic organization plan in work zone of Expressway ExpandingConstruction becomes reasonble,feasible and ecnomic.更多还原
