KUALA LUMPUR: The activation of a Smart Lane on the Kuala Lumpur-Karak Expressway (KLK) could not be implemented due to several factors, including its winding and hilly terrain, says Datuk Seri Alexander Nanta Linggi.

The Works Minister said the aspects that need to be considered before a Smart Lane can be activated on any part of an expressway are the width of the road shoulder and the geometric factors of the highway alignment.

"It is for this reason that the Smart Lane cannot be implemented on the KLK Expressway because the width of the road shoulder in the emergency lane is not sufficient for vehicles as well as the winding and hilly route along the expressway," he said during a question and answer session in Dewan Negara on Tuesday (July 30).

He was responding to a supplementary question from Senator Manolan Mohamad, who wanted to know if the government plans to implement a Smart Lane on the KLK Expressway to reduce congestion, especially on weekends.

Smart Lane refers to the controlled use of the road shoulder or emergency lane as an additional lane to increase the highway's capacity by dispersing traffic flow during congestion or accidents.

However, Nanta said the Malaysian Highway Authority (LLM) and concessionaire ANIH Berhad (ANIH) have planned several short-, medium-, and long-term actions to overcome congestion at KLK.

Among them is the implementation of lane channelization at several locations along the highway between KM64.3 near the Lingkaran Tengah Utama (LTU) intersection, at the U-turn at Maktab Rendah Sains Mara (MRSM) Bentong, and the slip road to Genting Highlands.
