为了计算城市道路网络的交通容量,结合现实中交通分布特征规律分析,考虑对过于迂回路线的限制与避免,并考虑道路通行能力的约束,建立了较能符合实际交通特征的城市道路交通网络容量计算方法.该方法在已知各起迄点对(OD对)间交通分布比例前提下,主要通过增量加载的方式来求算道路网络总容量.介绍了分析求解的具体步骤,并根据求解方法特点采用了多路径-增量加载分配方法来进行其中交通量的分配.算例表明,该计算方法用于求解城市道路交通网络容量是合理可行的.该方法可用于城市道路交通网络容量的评估及现状适应性的评价.

Combining an analysis of characteristics and rules of trip distribution in reality, the paper proposes the calculating method to determine urban road networks capacities, which avoids overlong bypasses and considers the restriction of road capacity. Based on the given proportions of trip distributions between all origin-destination (OD) pairs, the capacity is calculated by incremental loading of traffic. Detailed process and steps of solution is introduced, and the multiple path - incremental loading assignment method was applied with consideration of characteristics of the solution method. The numerical example proves the efficiency of the proposed method which can be used to determine urban road network capacity and evaluate the adaptability of present mad networks.
