通行能力的理论模型与道路条件和交通流的运行方式有密切的联系。本文对我国国道上环形交叉口道路及交通特性进行了分析研究。在此基础上以间隙接受理论建立了适于我国低渠化环形交叉口通行能力的理论模型。模型能较好地反映实际道路及交通条件的变化对通行能力的影响。对模型在实际工程中的应用进行了详细的阐述
The theoretical model of capacity is closely related to the way of the road and the operation of traffic flow. This paper analyzes the road and traffic characteristics of the roundabout in China’s national highway. On the basis of this, a theoretical model suitable for the capacity of circularly intersected low-channelized canal in our country is established based on gap acceptance theory. The model can better reflect the influence of actual road and traffic conditions on traffic capacity. The application of the model in practical engineering is described in detail
