【摘要】 混合交通流是我国城市交通的基本特征,也是造成城市交通拥堵的重要原因之一。特别是在平面信号交叉口,同相位不同方向行驶的机动车和自行车之间产生了大量的干扰,这些干扰严重影响了交叉口通行能力,同时极大地增加了安全隐患,给交通管理带来了难以治理的问题。微观行为模型是研究混合交通流机非干扰的有效工具,但目前国内外对机非干扰的行为研究还比较缺乏,尚未形成成熟的微观模型和完善的理论体系。在此背景下,论文结合导师的国家自然科学基金项目“平交路口混合交通流中机非干扰机理和基本参数的研究”,研究平面交叉口混合交通流机非干扰微观行为,以其中的直行自行车与同向右转机动车的干扰为例,侧重考虑机动车对自行车的干扰,建立机非干扰微观行为模型。具体研究流程如下:首先采用视频拍摄的方法分别在北京两个典型的平面交叉口采集混合交通流数据,并对数据进行整理和分析,获得机非干扰微观行为的各种数据和规律;然后利用实际数据和相关交通流理论,分别建立自行车自由行驶模型,自行车以及群穿越行为模型;通过以上模型的验证较为真实地反映机非干扰的实际情况,具有可行性和真实性。更多还原

【Abstract】 Mixed traffic flow, which is the main characteristic of large cities in China, is regarded as one of the primary reasons for serious traffic congestion. In the signalized intersection, great interference occurs between the bicycles and motorized vehicles which are in the same phase but heading for different directions. These interferences severely reduce the traffic capacity of the intersection, deteriorate the hidden trouble on traffic safety and make the traffic management very hard to be implemented. Model focused on microcosmic traffic behavior is one of the powerful tools for the study on mixed traffic, regardless the lack of mature and sophisticated model and the related theoretical system.Combined with one project under subsidy of National Natural Science Foundation conducted by my supervisor "Study on the mechanism and parameters calibration of interference between bicycles and vehicles in signalized intersection", this paper studies the microcosmic behavior of the interference between bicycles and vehicles in signalized intersection. Using the interference between straightforward bicycles and right-turn vehicles in the same direction as the case study, we build a mathematical model focused on the one-way interference of vehicles to the vehicles. The main steps we perform the study are summarized as follows: firstly, collect real traffic flow data of two classical intersections in Beijing by means of taking videos; then, analyze the collected data and try to obtain the useful data and principles existing among them; use the refined data and the related traffic flow theory to build the model for straightforward bicycles and bicycles platoons and through vehicles, respectively; Comparing the results with the real data, we find the model we build really reflects the real traffic flow in a very good manner, which justifies the validity of our model.更多还原
