题目：基于工程装置地城市交通通行能力提升研究 院 系 物流学院 专 业 机械设计制造及其自动化 班 级 学生姓名 郭晓薇 学 号 0894073119 导师姓名 王成林 导师职称 副教授City traffic is a measure of city symbol of civilization and progress, is the lifeline of city life.With the high-speed development of social economy, city changes a course accelerate, people living standard rises ceaselessly, city traffic demand rapid growth, appeared road builds more more, traffic is becoming more and more crowded phenomenon. Chinas population of over 1 million large city widespread severe traffic congestion, road network traffic load close to saturation, traffic congestion is becoming serious day by day, and by the center city to suburban sprawl, medium and small city also appeared generally the phenomenon of traffic jams.Therefore, in-depth analysis of the causes of traffic congestion, and the problem of root finding effective solutions, is the primary issue in the study of traffic congestion. Traffic congestion has become the constraints of our city logistics are important factors for city logistics constraints, more and more apparent, from current in light of the concept, the traditional design idea is highly dependent on vehicle road, update the road design concept, implementation of new traffic system construction strategy, boost the construction of modern traffic system. The article in question, solves the question method, in view of the present our country big city widespread traffic congestion, the problem of low efficiency, focus on the use of engineering and technical methods of solving these problems.
