摘　　要：城市过江通道作为沿江城市交通的重要节点,容易形成交通瓶颈。通过研究柳州城市过江通道交通现状,发现主城区内部跨江桥梁分布密度较高,平均间隔为1~2 km,联系柳东新区的跨江桥梁平均间隔为3~4 km,市区跨江桥梁交通流量分布不均,其中饱和度大于1.0的桥梁有两座。经计算后得出,现有的跨江桥梁还存在富余资源,根据预测,未来跨江桥梁交通流量分布将更为均衡,城市跨江桥梁交通流量及饱和度均呈上升趋势,平均饱和度将达0.78,超过半数的跨江桥梁交通流量将趋于饱和。City crossing river pathway as an important node of urban traffic along the river,which is easy to form the traffic bottlenecks.In order to studied the present situation of Liuzhou urban river pathway,the results showed that the distribution density of bridges across the river in the main urban area is relatively high,with an average interval of 1~2 km,and the average interval of bridges connecting Liudong New District is 3~4 km,the traffic flow of bridges across the river in urban areas is unevenly distributed,there are two bridges with saturation greater than 1.0.After calculation,there is a certain amount of surplus resources of the existing bridge across the river,according to the prediction,the traffic flow distribution of bridges across the river will be more balanced in the future,the traffic flow and saturation of bridges across the river in the peripheral areas of the city will increasing significantly,the average saturation will reach 0.78,and more than half of the traffic flow of bridges across the river will be saturated.
