A method and system to enable charging for road usage is described. Each vehicle must carry a usage permit having a number of sections representing discrete time periods. If a vehicle is to be used during one of these time periods, the relevant section of the permit must be visibly activated and the permit clearly displayed in the vehicle. Once the section has been activated, this is irreversible and any attempt to reverse the activation is immediately apparent upon inspection of the permit. When the permit is surrendered, it is inspected to determine the number of activated and/or non-activated validity sections and a debit or credit due against the permit is determined dependent upon the number of activated and/non-activated sections. In this way, the vehicle user is rewarded for infrequent use of the vehicle and penalised for frequent use. |
