We thank Mr Leong Cheng Kong for his letter “Why charge ERP on Saturday evening?” (The Straits Times, 4 June).
It is necessary to implement Electronic Road Pricing (ERP) in the Bugis-Marina Orchard cordon on Saturdays because traffic in the area is heavy. The cordon concept, where all routes entering the same area are priced uniformly, is applied for the city area because the roads leading into the city area are fairly good substitutes for one another. If roads were charged individually, traffic would divert into substitute roads that are not priced or are priced lower, resulting in greater localised congestion.
With the implementation of ERP on Saturdays for the Bugis-Marina Orchard cordon, traffic speeds within the cordon have been kept within an optimal range of between 20km/h and 30km/h.
We thank Mr Leong for his feedback and the opportunity to clarify.
