| 摘要: |
| 采用人工记数法对北京市区某典型拥挤路段6个相关路口全天6个时段的机动车和非机动车交通量进行了观测．根据流向建立了该路段不同时段的交通量观测表和流量流向图，以及相应路口的交通量基本数据库。运用交通工程理论和方法分析了该路段的交通特性和变化规律。结果表明．该路段道路容量和通行能力明显不足：提出了改善该路段交通状况的措施：增加该路段道路容量，提高道路通行能力，加强高峰时段路口交通管理与控制，规范行车秩序．等等。调查所得结果可作为有关部门改善城区交通拥堵状况、预测未来交通流状态、规划交通路网等的决策依据。 |

| Abstract: |
| The traffic flow of motor-vehicles and non-motor-vehicles was observed with method of man-accounting six periods of time in a day at typical congesting road in Beijing, and created observation tables, figure and database of every intersection for traffic flow with flow-direction, then the characteristics and changing rules of traffic flow were analyzed. The capacity of the section can't meet the need of driving car, and driving cars in the south-north direction must wait for multi-queue at the intersection, which arouse badly traffic congesting pre-post sections, the capacity and improving status of traffic, traffic management and control, traffic order should be typically thought over. These results are real and reliable, which are offered for some department of decision-making to improve the traffic congestion, forecast status of traffic flow and program traffic road-net. |
