An origin–destination based road pricing model for static and multi-period traffic assignment problems

• We analytically derived origin–destination (OD)-based tolls for elastic demand.
• We derived user equilibrium conditions for multi-period static traffic assignment.
• OD-based toll pricing model for the multi-period static traffic assignment problems.
• Practical advantages of the proposed OD-based pricing over existing schemes.
• The origin–destination based pricing scheme outperforms the no-toll scenario.

To mitigate traffic externalities, we propose an origin–destination (OD) based road pricing model for traffic assignment problems. For elastic demand, we derive explicit optimal tolls for the OD-based pricing scheme. We also extend the model to a multi-period static traffic assignment (MSTA) where we derive analytically the route and OD-dependent tolls based on equilibrium conditions. We present some examples to show that the OD-based tolling scheme could improve the system welfare significantly, compared to the no-toll scenario (user equilibrium – UE).
