【摘要】:在我国机动车保有量不断激增和混合交通特征愈发明显的情况下,平面交叉口俨然成为事故的多发地带。因我国交通法规针对右转车流不予信号控制,使得右转机动车与直行机动车的汇入冲突、非机动混合交通流的交叉冲突表现的越来越突出。为了改善平面交叉口的运行效率,保障多方交通行为者的行驶安全性,本文主要通过分析信号控制交叉口的右转机动车与直行机动车、直行非机动混合交通流的冲突机理,对右转系统控制进行方法研究。本文对平面交叉口右转冲突进行界定和过程分析。首先,基于交叉口右转冲突调查基础上运用数据统计,解析和验证了交叉口直行车的交通流特性,确定了直右汇入冲突规律,建立了直右汇流车道通行能力模型。其次,对非机动混合交通流在交叉口的运行特性、饱和流率、速度进行调查分析,建立了到达流率与右转延误的函数关系模型,从而确定了非机动混合交通流集聚流部分成为右转冲突主要因素。针对直右机动车冲突、右转机动车与非机动混合交通流冲突右转信号控制方法进行了研究。从冲突机理出发运用直右汇流车道通行能力模型计算分析确立了直右机动车冲突右转信号控制的阈值。又根据非机动混合交通流到达流率的不同对右转冲突影响大小不一的特点进行量化分析,共分为三种控制策略,即不开启右转控制、半开启右转控制和完全开启右转控制。研究确定非机动混合交通流的饱和流率值为完全开启状态的右转控制阈值;非机动混合交通流到达流率与右转延误关系模型切点为右转控制半开启状态控制的阈值,并分析半开启控制的具体信号配时方法,在函数关系模型切点阈值以下不予右转控制。右转信号精细化控制为信号控制的科学有效性提供理论基础。最终,将两种控制方法整合成针对信号交叉口系统性的右转控制方法。以实际路口为例运用微观交通仿真软件VISSIM建立仿真模型,验证右转控制方法的可靠有效性,采取了无右转控制、右转定周期控制、本文研究的右转自适应感应控制三种控制方案进行仿真对比。通过对比结果发现,运用本文的自适应感应控制方法,有利于缓解右转冲突,减少冲突车流的行车延误,提高了通行效率,为解决平面交叉口右转冲突矛盾提供指导性依据。
[Abstract]:With the increasing number of motor vehicles in our country and the increasingly obvious characteristics of mixed traffic, intersections have become an accident prone zone. Because traffic regulations in China do not control traffic signals for right-turn traffic, In order to improve the operation efficiency of intersections and to ensure the safety of multiple traffic actors, the conflict between right-turn vehicles and direct vehicles is becoming more and more prominent, and the cross-conflict of non-motorized mixed traffic flows is becoming more and more prominent. This paper mainly analyzes the conflict mechanism between right-turn vehicle and direct motor vehicle at signal-controlled intersection, and direct non-motorized mixed traffic flow. The method of right-turn system control is studied. This paper defines and analyzes the right-turn conflict at intersection. Firstly, based on the survey of right-turn conflict at intersection, we use data statistics. This paper analyzes and verifies the traffic flow characteristics of the direct vehicle at the intersection, determines the law of the straight right confluence conflict, and establishes the capacity model of the straight right concourse lane. Secondly, for the operation characteristics of the non-motorized mixed traffic flow at the intersection, the saturated flow rate is obtained. The velocity is investigated and analyzed, and the function model of arrival rate and right-turn delay is established, and it is determined that the concentrated flow of non-motorized mixed traffic flow is the main factor of right-turn conflict. The right-turn signal control method of right-turn traffic conflict between right-turn motor vehicle and non-motorized mixed traffic flow is studied. Based on the conflict mechanism, the right-turn signal control of right-hand motor vehicle conflict is established by calculating and analyzing the traffic capacity model of the right-hand confluence lane. According to the different arrival rate of non-motorized mixed traffic flow, the impact of right-turn conflict is different. There are three control strategies, namely, not turning on right turn control, half turn on right turn control and full turn on right turn control. The saturation flow rate of non-motorized mixed traffic flow is determined to be a fully open right turn control threshold. The tangent point of the model of non-motorized mixed traffic flow arrival rate and right-turn delay is the threshold of right-turn control semi-open state control, and the signal timing method of semi-open control is analyzed. There is no right turn control below the tangent threshold of the function relation model. The precision control of the right turn signal provides the theoretical basis for the scientific validity of the signal control. The two control methods are integrated into a systematic right-turn control method for signalized intersections. Taking the actual intersection as an example, the simulation model is established by using the microscopic traffic simulation software VISSIM to verify the reliability and effectiveness of the right-turn control method, and the no-right-turn control is adopted. The right turn adaptive induction control is simulated and compared with the right turn adaptive induction control. The results show that the adaptive induction control method in this paper is helpful to alleviate the right turn conflict. It can reduce the traffic delay of conflict traffic, improve the traffic efficiency, and provide the guidance basis for solving the contradiction of right-turn conflict at intersection.
