As each city has its unique traffic patterns and characteristics, so too are the strategies implemented to keep traffic flowing and to motivate drivers to modify their travelling habits. These strategies typically involve access control and charging policies implemented over a specific urban area reflecting the objectives of the policy makers and the specific priorities of the locality.

Dynamic Parking is a time-based approach to on-street parking whereby the vehicle is charged for time spent within a defined area (“physical presence”). Depending on the policy, the charge may begin when entering the zone and end when leaving the zone. Since the system can be configured to count vehicles in the zone, it is possible that the number of available parking spaces can be indicated. This method can be used as part of an overall parking strategy in conjunction with off-street or privately provided parking facilities, for instance.
