Announced by Transport Minister Raymond Lim on Friday evening, the initiative will cover public transport, chartered buses, school buses and taxis.

The initiative involves transport organisations sending their staff for service training and going overseas to study service best practices.

ComfortDelGro Bus, Woodlands Transport Service, SBS Transit, SMRT and Transit Link will send a total of 13,900 transport workers including bus captains and operations personnel for training.

Together with taxi drivers, who from February have been part of the CCI for taxis, 80 per cent of transport workers will be involved.

The CCI started with the retail sector in 2005 and has been extended to the food and beverage, healthcare and transport sectors.

Said Mr Lim, speaking at the 27th Anniversary Dinner of the National Transport Workers' Union (NTWU): 'Our transport workers, especially frontline personnel, will play an increasingly important role as we move towards our vision of a people-centred land transport system.'

Agreeing, Mr Yeo Guat Kwang, co-chairperson of the CCI Committee said: 'There is no better time than now for the land transport sector to get on board CCI to boost the industry's image and professionalism.'

'This will lead to better service performance that will ultimately benefit commuters and help transform our land transport sector to be the best in the world.'
