With the rapid expansion of mass
transit system (公交体系), big cities like Shanghai should be able to ease the congestion(拥挤)and pollution caused by an excessive number of cars.
Statistics show that Shanghai’s subway lines will reach 350 km by the end of this year, making the city No. 3 in the world in terms of subway length. Shanghai could be ranked No. 1 when the length is extended to 430 km next May in time for the World Expo. This means about 5.5 million people each day could use the city’s subway system, thereby reducing traffic bottle-necks and air and noise
pollution in downtown Shanghai.
At present, Shanghai suffers from
severe traffic congestion, during not only rush hours and weekdays but also
off-peak hours and weekends.
For years, car emissions (尾气) have been blamed for
contributing 60 percent of the air pollution in the city center, causing
various respiratory (呼吸道) diseases.
What’s more, Shanghai has not met
its target of noise reduction for five years, which has become a major source
of public complaints. Starting from August 1, cars that are considered highly
polluting will be banned from entering the city centre.
Shanghai also plans to carry out the China IV
emission standards, equivalent to Euro IV, on November 1, ahead of the 2011
national deadline. In addition, Shanghai is building 16 parking lots with 8,000
spaces near subway terminals so that people can park and ride the mass transit
system instead of driving their cars into the city center.
Much more needs to be done for
truly easing the traffic jams and air and noise pollution caused by
automobiles. For example, the ban on using the horn, which was made effective
from June 1, 2007, has hardly been enforced.
Many local people still regard
owning and driving a car as a kind of demonstration of their wealth, without
realizing the traffic and environmental hazards it can cause. When the
subway system can take people to their destinations, driving a private car in
downtown Shanghai could become a moral issue.
Shanghai should also show courage in leading Chinese
cities to adopt the congestion charge system, which the city has been studying
for the last eight years. A similar schedule, practiced in London and Singapore, has proved to be effective in reducing pollution and congestion in the city
center.
Once Shanghai shows the way,
other cities, like Beijing, too, may adopt the practice.
