公路改造是城镇发展的大势所趋,原有公路沿线的城镇发展既推动着公路改造,也在一定程度上制约着公路朝快速化市政化发展。因此,不少地区采用近、远期结合的方式,先行开展公路节点改造工程,以“点”为始,逐步实现公路的快速化和市政化。... 公路改造是城镇发展的大势所趋,原有公路沿线的城镇发展既推动着公路改造,也在一定程度上制约着公路朝快速化市政化发展。因此,不少地区采用近、远期结合的方式,先行开展公路节点改造工程,以“点”为始,逐步实现公路的快速化和市政化。文章通过对中山市古镇快线(沙古公路)快速化改造工程的方案研究过程的阐述,分析确定在满足交通功能的前提下,公路快速化过程中节点改造可能面临的问题及其解决办法,使节点改造与既有道路、土地利用、房屋建筑及其他控制因素等相适应,可供相关研究参考。 展开更多

As a typical car-dependent city, Los Angeles (LA) is extensively used as an example in research to illustrate car influences on city form. Focusing on the features of LA's geologic conditions and civil circumstances, we argued that the relationship between LA's low-density pattern and car dependence is more involved than previously deemed simple causality. The low density should be primarily credited to the spacious requirement of the mining industry, frequent earthquakes and multiethnic population of the city. Off reserves in LA fueled its economic boom and fast urbanization that coincided with the start of mass production of cheap cars, and cars became medium-priced consumables for average families. Politicians preference for short constrnction-period projects enabled fast establishment of LA's highway infrastructure. The popularity of car use in return faciliatated further development of the low-density pattern of the city. The low-density urban form and car dependence created environmental and social problems for LA. Looking at P. R. China's motorization and urban development, we found that the trajectory of Beijing's motorization between 197g and 2003 coincides with that of the U.S. in the 1910s and 1920s. Lessons from LA's urban and transportation development should be suggestive to China's urban and transportation planning. 展开更多
