Speed limit on KPE set to increase to 80km/h

The Straits Times reported that speed limit for the Kallang-Paya Lebar Expressway (KPE) is set to go up from 70km/h to 80km/h from next month - six years after the largely underground highway opened.
It is understood that the limit will be revised to be in line with the limit for the Marina Coastal Expressway (MCE), which opens at the end of the year. The KPE joins the MCE, which also joins the Ayer Rajah Expressway (AYE).
Checks by the local paper revealed that new speed limit signs, covered in black plastic wrappers, have been placed in the tunnels. But certain stretches with sharper curvatures may retain the 70km/h limit.
Associate Professor Wong Yiik Diew, who teaches road transportation at Nanyang Technological University, said that the two highways 'may appear disjointed if there were two different speed limits'. An academic paper Prof. Wong co-wrote with PhD student Yeung Jian Sheng found that most tunnel accidents in Singapore happen at the entrance or exit.
One factor cited was the different speed limits between the surface road and tunnel section. But the paper found the accident rate in tunnels was on the whole lower than the rate on surface highways.
Regular users of the KPE welcomed the new speed limit, saying traffic in the tunnels is often not heavy, and does not warrant such a conservative cap.
