Parking policies are often recommended as tools for travel demand management that have little to no implementation costs associated with them. Furthermore, in comparison to other travel demand management policies, the risk of resistance is rather low. The City of Rosario, Argentina, began implementing metered parking policy in May 2001. Since then, zones regulated by metered parking have spread to cover most of the city center.
The policy had the dual stated objectives of discouraging motor vehicles from entering the area and prioritizing the use of parking spaces for limited-duration rather than full-day parking.
