摘要
交通量调查是交通规划、交通组织、交通管理控制的重要基础。在交通设施不完备的情况下,目前常用的人工交通流量调查法,工作量大且对调查人员要求较高。为了提高交通流量调查效率,降低调查工作量,文中依据交通流基础理论,构建了交通流量与排队长度的分布和拟合的模型。通过信号交叉口红灯期间排队车辆长度来快速计算通过交叉口的交通流量。最后应用实际验证表明:文中方法调查误差均小于10%,符合工程实际应用需要。
Traffic investigation is an important basis of traffic planning,traffic organization and traffic control.At present,the traffic flow survey method commonly used in traffic volume is heavy and has high requirements on investigators.In order to improve the efficiency of traffic flow survey and reduce the workload of investigation,from constructs distribution and fitting model of traffic flow and queue length according to traffic flow theory.Quickly calculate the traffic flow through the intersection by queuing the vehicle length during the red light at the signalized intersection.Finally,the actual verification shows that:the error of the survey method is less than 10%,in line with the practical application of the project needs.
