摘　　要：中国城市化率、机动车普及率不高而城市交通拥堵已经世界闻名。历来认为交通拥堵的原因是人口和机动车数量过多、交通基础设施不足,因此为了治堵而限制人口迁徙、限制机动车的购买和使用。事实上,拥堵的本质是过密,路网结构不合理是中国城市拥堵的重要因素。与日本比较发现,中国城市不仅道路面积率较低,而且封闭式大院分割地面造成路网稀疏,交通路径选择性较小。过度密集的居住方式使人均道路面积、长度小,道路连通住宅、学校等城市功能点的机会较少,道路可达性低。因此,提高建设用地比重、交通用地比重,避免封闭大院街区,建设开放的稠密道路网以提高通达性,可以提高交通效率。China＇s urbanization rate, motor vehicle penetration rate is not high and the urban traffic congestion has is famous all over the world. The cause of Traffic congestion is always considered to be too much population and the motor vehicles, the lack of transport infrastructure. So in order to control congestion by limiting the popuhtion migration and the purchase, use of motor vehicles. In fact, the essence of congestion is too close, the unreasonable smacture of road network is an important factor in Chinas urban congestion. Compared with Japan, found that China＇s urban road area rate is low, not only the enclosed compound caused that lack selective of the traffic path. Excessive intensive way of living has reduced the per capita road area and length . oppom.mity of the road connecting the city function point such as homes, schools is less, accessibility of road is low. Therefore, to raise the proportion of construction land and transportation land ,to avoid sealing block, to construct open dense road network in order to improve accessibility, Can improve traffic efficiency.
