Case Study: Highway Toll system
• Vehicles using the highway have their license plates scanned at entry and exit points
• Charge is calculated based on:• Distance travelled• Type of vehicle
Day of the week, time of the day• Day of the week, time of the day• Subscription plan (for frequent users)• Etc
• For subscribers, usage is summarized and mailed as a monthly report
• For non-subscribers, bills are summarized and mailed on a weekly basis
