摘要
通过交通调查数据,结合城市交通的特点,分析了城市道路交通流的车种构成;使用规范建议的方法,对各种车辆的轴载进行标准换算,计算各种车辆在道路交通荷载中的比例。通过分析指出设置公交专用道将导致道路交通荷载在横向的严重不均匀分布;从荷载分布的角度,进一步讨论了公交专用道对道路使用状况等产生的不良影响,并提出了解决问题的方法和途径。
Combined with the characteristics of urban transportation,vehicle composition of urban traffic flow was analyzed.Employing the method which is suggested in the criterion, contribution proportion of vehicles for traffic load was calculated by axel load conversion. Therefore, obvious asymmetric distribution of traffic load on lateral direction would be brought to urban road in result of bus lane.From the viewpoint of load distribution, the approaches to the problem that negative effect on road working was put forward.
