The rate or price is the amount that a manager or operator charges for a service or product. It results in a financial transaction between the two parties. The customer acquires a right (e.g. to park his/her vehicle in a car park) in return for payment of an amount due for this right to the service provider (in this case, the car park operator).
The rate is imposed by the car park operator and cannot be contested or negotiated by the customer. In most cases, rates are applied on an hourly basis, i.e. the price is calculated according to a pre-defined hourly rate, which the service provider uses to set the price of its services.
Car park rates generally cover the cost of parking a vehicle in the car park concerned. Where a car park has a security guard service or is fitted with CCTV (as is the case with all Paris France Parking car parks), the rates charged are generally higher than at car parks without such security systems.
