Singapore Electronic Road Pricing

Singapore's Electronic Road Pricing (ERP) is a system that manages traffic congestion by automatically charging vehicles for using busy roads during peak times. Using electronic sensors and in-vehicle units, the system detects when a vehicle passes through a priced zone and deducts the fee from a preloaded account. The charges vary based on traffic conditions, encouraging drivers to avoid congested routes or travel during off-peak hours. This technology helps maintain smoother traffic flow, reduces congestion, and balances road usage efficiently without physical toll booths, making urban travel more sustainable and predictable.
