Debated in Parliament on 12 Nov 2012.
Mr Yee Jenn Jong asked the Minister for Transport (a) how are the quantum of ERP rate changes determined at each quarterly review; (b) whether a maximum ERP fee is set at any single gantry; and (c) how does the Ministry look at the traffic congestion data for the planning of road capacity.

Electronic Road Pricing (ERP) rates are set by the Land Transport Authority (LTA) based on the latest traffic conditions on the affected stretch of road. At each quarterly review, ERP rates are adjusted, generally by $1, when traffic speeds fall outside the optimal range of 45 km/h to 65 km/h on expressways, and 20 km/h to 30 km/h on arterial roads. There is no maximum fee set at any gantry.
New roads are planned to cater for the increase in travel demand along key corridors and to enhance the overall road network. When planning road capacity, LTA takes into account existing and projected traffic conditions, considering the growth in residential, commercial and industrial developments in various parts of Singapore, and also the addition of new MRT lines, demand management measures such as the ERP and lowered vehicle growth rates, which would encourage a shift in travel mode towards public transport. LTA works closely with other Government agencies such as the Urban Redevelopment Authority (URA), in its transport planning.
