The Land Transport Authority (LTA) is expanding a traffic light scheme that gives elderly pedestrians more time to cross the road to 239 more locations.

It will call a tender in May this year to expand the "Green Man Plus" scheme to another 239 pedestrian crossings. Works will begin in the fourth quarter of this year and be completed by 2015. When completed, there will be 495 pedestrian crossings under this scheme in 30 housing estates, up from the current 256.

Introduced in October 2009, the scheme gives senior citizens and disabled pedestrians more time to cross the road when they tap their cards on the card reader on the traffic light pole. The crossing duration is extended by six to 13 seconds, depending on the size of the crossing.

Said Dr Chin Kian Keong, LTA group director for road operations and community partnership: "We have received positive feedback and suggestions since the implementation of the Green Man Plus scheme. When the second phase is completed in 2015, more elderly and disabled pedestrians will benefit from a comprehensive coverage of Green Man Plus."
