Anyway, some effective approaches have been adopted to improve the public transportation by government. Firstly, the road construction gives prior consideration to public goods. For example, many big cities like Xiamen has built up a highway network, called BRT(Bus Rapid Transit)system, which is only accessible for buses. Needless to say, this will dramactically clear away the traffic jam even at highpeak period. And referring to the train system, government has invested large sum of money not only to expand the net of tracks, but also to carry out more advance technology on lifting up the speed. Furthermore, special rules have been applied to strictly control the number of private cars. For instance, in Shanghai, the car plates are auctioned in regular ammont per month rather than released randomly to whoever boutht a car. Though all these efferts are greatly bettering the transport situation of cities, what's more important is the public awareness.
