Road Pricing

• Manual road pricing introduced in the Central
  Business District (CBD) since 1975
• High manpower needs, inconvenient, limited in
  varying road pricing charges

25
Electronic Road Pricing (ERP)

• Automated with the Road Pricing system (Area
  Licensing Scheme, ALS)
• Fully replacing the manual scheme in Sep 98
• A new generation of
• ERP is being studied

Remarks

• gtS420 million (US233 million) has been spent
• gtS0.6 million per km of major road
• gtS600 per vehicle
• Earlier (pre-2000) systems are independent
  isolated
• Already moving into 2nd generation of integrated
  and interoperable system

51
Remarks

• ITS technology testbed
• Integrations
• ITS systems, deployments
• Transport technologies, transport policies, land
  use, and urban development
• Emphasis on operation and sustainability instead
  of ad-hoc deployments
• ITS business model
