Social funds, including funds from overseas, should be encouraged to invest in public transportation in the forms of joint-ventures, cooperation or entrusted operations, said an official with the Ministry of Construction on Tuesday.

Public transportation enterprises should be encouraged to raise fund through making flexible use of current assets and going public, said the official who declined to give name.

The official noted that construction of public transportation infrastructure and surrounding real estate development should be planned as a whole.

Public transportation enterprises should allocate vehicles and map out courses scientifically so as to shorten the waiting time of passengers, the official said. Safe, cozy, energy-saving and environment-friendly vehicles should be chosen for public transport, and the vehicle upgrade process should be accelerated.

The maintenance of public transportation stations, vehicles and relevant facilities should be enhanced so as to create a still better environment for passengers, the official said.
