Pledging to improve the life quality of its residents, Shanghai has set the year 2010 as the deadline for "obvious improvement" in its public transportation.

At the same time, the registered unemployment rate for the next five years will be maintained at around 4.5 per cent.

At the Fourth Plenary Session of the 12th Shanghai Municipal People's Congress, yesterday's group reviews stirred heated debate among the deputies.

Public transport

For the next five years, Shanghai will give full priority to the development of public transportation. Already on the agenda is a leap from the present 123 kilometres to 400 kilometres of metro lines, and growth from 23.7 kilometres to at least 100 kilometres of dedicated bus lanes, said Vice Mayor Yang Xiong at yesterday's group discussion.

The difficulty passengers have in transferring between the metro and buses and the incomplete public transport network, will also see improvement, he said.

A newly released survey by the municipal government shows that by the end of 2004, only 23.7 per cent of people who travel around the city choose public transportation. If taxi users are excluded, the figure stood at around 18.5 per cent. This number is one percentage point lower than the number from a similar survey in 1986, even though there are more buses available than there were 20 years ago.

"Due to the slowness and inconvenience of taking public transportation, many people would rather ride bikes or motorcycles when they go to work," said Xia Liqin with the Shanghai Decisionmaking and Consulting Commission.

The problem will be alleviated in the next five years when more metro lines are put in use, she said, but the pressure from heavy traffic on roads will still be intense.

According to Congress deputy Wei Ming, the number of vehicles in the city increases by around 100,000 every year. The city has now more than 1.8 million vehicles.

A reshuffle of some the city's bus routes is possible. With the construction of more metro lines, the city will shift some bus routes from the urban area to the suburbs, which are still short of public transportation.
