【摘要】 交织区是高速公路系统的瓶颈路段,为给规划、设计、运营等各阶段选择科学合理的交织区运行分析方法,通过对国内外大量研究文献的分析,首先详细综述了交织区运行分析采用回归分析法、理论解析法和微观交通仿真法的研究成果;然后探讨了各种方法的特点,从交织区构型分类、交织区长度和宽度、影响因素选择及相关模型、服务水平指标及其分级4个方面的历史演变对回归分析法进行了评析,以间隙接受理论为例说明了理论解析法存在的问题,阐述了微观仿真法的关键步骤和难点,指出了我国在高速公路交织区研究中存在的主要问题;最后结合我国交织区运行分析现状和交通领域研究热点,探讨了高速公路交织区研究发展方向。结果表明:交织构型的划分趋向于单一化,有利于提高交织区运行分析模型的普适性;现有通行能力模型未考虑大型车比例和出入口匝道通行能力等影响因素;服务水平评价指标还需考虑交织区的紊乱程度。交织区数据采集方式、通行能力建模、服务水平评价标准、微观交通仿真、特殊交通运行环境下交织区运行分析、交织区运行分析应用研究是未来发展的方向。更多还原

【Abstract】 Weaving area is the bottleneck of expressway system. In order to choose a scientific and reasonable weaving area operation method for stages of planning,design,operation and so on,through the analysis of a large number of literatures on weaving area at home and abroad,first,the research results of regression analysis,theoretical analysis and microscopic traffic simulation of weaving area are reviewed in detail. Then,the characteristics of various methods are discussed,the regression analysis is evaluated and analyzed from the historical evolution of 4 aspects,including structure classification,length and width of weaving area,selection of influencing factors and correlation model, service level index and classification. The gap acceptance theory is used as an example to illustrate the problems in the theoretical analysis method,the key steps and the difficulties in the microscopic simulation method are described,and the main problems in the study of expressway weaving area in China are pointed out. Finally,combining with the current situation of operation analysis of the weaving areas in China and the research hotspot in the transportation field,the research and development direction of the expressway weaving area is discussed. The result shows that( 1)the division of the weaving configuration tends to be simple,which is beneficial to improve the universality of the weaving area analysis model;( 2) the existing capacity model does not consider the influencing factorssuch as proportion of large vehicles and capacity of exit and entrance ramps;( 3) as for the service level evaluation index,the degree of disorder in the weaving area is also need to be considered. The data collection method,modeling of traffic capacity,evaluation standard of service level,microscopic traffic simulation of weaving area,operation analysis of weaving area in special traffic environment,and application of operation analysis of weaving area are the directions of future development.更多还原
