基于城市道路阻抗模型的开放式小区道路规划

Open community road planning based on urban road impedance model

利用交通流理论中的路阻函数,建立综合了直行路段、十字路口左转、右转通行时间与机动车道交通负荷比的理论模型。此外,根据对北方平原城市常见小区道路结构,提出了四种常见的小区道路规划方案,并根据理论模型选出方案最优解——循环型结构。着重分析了道路交通高负荷比的情况,为新型开放式小区规划提出建设性意见。

By using the road impedance function in traffic flow theory, a time-to-road saturation ratio model for straight road and left and right turning on the crossroad was buih. Besides, according to the common road structure in communities in Northern China, four open community road plans were proposed. The circular structure was selected as the optimal solution of the plans. Furthermore, the high vehicle saturation ratio was particularly discussed.
