ERP needed to control AYE congestion

Media Replies 23 Aug 2014

We refer to recent letters in The Straits Times on the new Electronic Road Pricing (ERP) gantries along Ayer Rajah Expressway (AYE).

LTA adopts a holistic approach to manage traffic congestion by applying all available tools such as intelligent transport systems, traffic engineering solutions, ERP, the Certificate of Entitlement (COE) system to control the vehicle population, road widening and most importantly, encouraging people to switch to public transport.

For the past several years, we have been closely monitoring traffic conditions along AYE. Traffic speeds have consistently remained below the expressway optimal speed range of 45km/h to 65km/h along two sections of AYE – AYE (City) between Jurong Town Hall Road and Clementi Road during both the morning and evening peak hours, and AYE (Tuas) after North Buona Vista Road during the evening peak hours. This traffic situation is expected to worsen due to new developments in the area.

Besides ERP, we are improving the road network in the area. For example, plans are in place to widen Clementi Road and Commonwealth Ave West (towards Jurong). However, such road improvements can only bring about limited relief to congestion as the wider roads will likely attract more motorists to use the corridor. With more than 12% of our land already used for roads, there is a limit to how much more we can expand our road network. Our priority is to build roads to serve new developments, facilitate the movement of buses for public transport commuters and support economic growth.

On the other hand, ERP has been effective in relieving congestion by encouraging motorists to switch their time, route or mode of travel. Motorists who do not wish to pay ERP during operating hours, can use alternative routes such as the West Coast Highway, which have sufficient capacity.

We are also improving public transport services in the west. To cater to ridership growth as more residential developments come up in Clementi, more buses and more bus trips during the peak periods have been added under the Bus Service Enhancement Programme (BSEP). For example, more buses have recently been added to Services 78, 173, 185 and 963.

We thank readers for their feedback.
