Editing Area Licensing Scheme (section)

==Road Pricing Scheme (RPS) extended ==
In 1995, congestion pricing was also implemented in urban segments of three major expressways, starting with the East Coast Parkway (ECP). The RPS, as it was called, also operated manually with paper licences to enter the expressways. In 1997, the RPS was implemented in the Central Expressway and the Pan Island Expressway. After the implementation of RPS, the Central Expressway Average speed at peak hour went to 67&nbsp;km/h from the previous average of 31&nbsp;km/h.<ref name="auto"/> This extension was necessary because some through traffic was diverted by the ALS to routes that bypassed the RZ, increasing demand on these arterials and creating a need for expanding the capacity of the road network outside the RZ. Because of heavier demand, only the Central Expressway required a separate licence, not valid for the RZ. During this time, a more modern system was being planned, to charge every time a user entered the RZ, and thus, charges would reflect the true cost of driving at congested times.
