摘要:城市路网是城市交通与城市发展的骨架,但关于路网密度、合理间距并未得到充分认识。居民每次出行的总时间一般包括城市干路内的时间和干路所围合的街区内的出行时间,合理的干路网密度应当使二者之和最小。根据这一原理,构建了居民出行效率分析法,对合理的街区尺度、路网间距进行了推导。根据这一方法,得出如下结论:不同交通方式、不同距离出行所要求的合理街区尺度不同;即使优先考虑机动车的出行效率,路网密度所起到的作用也不可能通过宽而稀的路网来实现。

Abstract: road network is important for the development of city, but the theory about planning of road network is not talked enough. The total trip time enclose the time used in block and out of block, reasonable density of road network should make the total trip time to be least. According to this theory, papers analyzed the efficiency of the traveler. How to find reasonable distance between roads and how to find reasonable width of block is given in the paper. Conclusion that reasonable distance between roads is different for different traffic modes and different trip distance was drew in the paper. If road network is only designed for motor vehicle, the role of density of network cant be displaced by the sparse network with wide road.

Keywords: efficiency of the traveler; reasonable distance between road; block scale
