What the picture isintended to convey is that the swift development ofprivate car meets with the requirements of peoples traffic demand, but alsoarouses the negative externality. Heavy transportation pressure in many citiesmay bring much inconvenience to people and exert adverse impacts on theenvironment. On the one hand, when traffic jam happens, short distance in thepast now seems to become terribly long, and drivers could do nothing but towait. Therefore, a lot of precious time has been wasted on the road. On theother hand, exhausted gas emitted by cars has increased the burden ofenvironment, air pollution and its health impact is becoming a bigger concernin china's smoggy capital.
Therefore, effective measures should be taken toalleviate the traffic jam. Firstly, planned development of the number ofprivate cars should be carried out. Secondly, public transportation such asbuses and subways, which are low-carbon transportation means, should beencouraged and promoted. The effective implementation of the measures mustbenefits the coordinated development of society and economy, environment andecology.
