交通拥堵反思

通过对交通拥堵进行反思,认为交通拥堵是充满活力的成功城市的伴生品,应从不同角度考虑拥堵问题.提出了十项有别于传统观点的提议,主要包括:机动性至关重要,交通拥堵是社会、经济活力的象征；道路扩容效果短暂,并会诱发潜在需求,但仍可带来一定的社会、经济效益;土地使用对出行行为的改变需要长期的努力；紧凑型发展会加剧交通拥堵；降低...

Rethinking Traffic Congestion

Through reflective think-ing about traffic congestion,this pa-per states that traffic congestion is inevitable for vibrant and successful cities,and should be viewed in a different perspective.Thus,ten propositions that challenge conven-tional ideas are proposed by the pa-per which include： mobility is es-sential to metropolitan life;traffic congestion signalizes a city’s so-cial and economic vitality;capacity expansion is shortlived to elimi-nate congestion,and induces latent traffic demand,but it may still bring significant social and eco-nomic benefit by accommodating more activity;changing travel behavior through land use development is a very long-term endeavor;compact development increases congestion;the best way to get more people to walk and utilize public transit is to make car com-muting less attractive（low speed,not reliable and costly）;without any pricing policy to discourage car use,the best way to combat traf-fic congestion may come from the development that favorable for car commuting.Finally,the paper points out that road and parking pricing probably offer the best opportunities for reducing congestion over a longer term,and for any development strategies,congestion reduction is just one of many objectives.
