Land Transport Authority (LTA)
• Established in 1995• Under Ministry of Transport• Single agency responsible for land transport
policy, facilities, operations and management• ITS has been adopted as a main strategy
ITS in Singapore
LTA’s White Paper
Multi-pronged strategy
Integrated planning
Expansion of road network
Improve public transport
Demand management
Harness advanced technologies

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

Automated Taxi Dispatching System
• Based on DGPS receivers and wireless private networks
• Adopted by all operators
• Approximately 100,000 dispatches a day
ITS in Singapore
TrafficScan• Based on speed gathered by taxis with DGPS
receivers

ITS in Singapore
Remarks• >S$420 million (US$233 million) has been spent
– >S$0.6 million per km of major road
– >S$600 per vehicle
• Earlier (pre-2000) systems are independent & isolated
• Already moving into 2nd generation of integrated and interoperable system
ITS in Singapore
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
