Abstract
Abstract Charging apparatus for use in a road vehicle enables an authority to charge for road usage. As the vehicle is used on controlled parts of road way, debiting means debits credit units at a predetermined rate. A store keeps a record of the credit units used. The debiting rate can be preselected. An alphanumeric display can be visible through the windscreen of the vehicle to enforcement officers as the vehicle passes. The display can show the debiting rate currently in use. A pre-payment credit card system may be employed to charge the apparatus with credits. An internal display for the driver allows the driver to select the debiting rate demanded by signs along the controlled roadway.
