A state transport agency has recently launched electronic ticketing machines (ETM) for fare collection and accurate auditing for its bus transport system. When a trip begins, the ETM machine number and the identification numbers of the conductor and the driver are transmitted to the agency’s server and a unique number is generated for the trip. This number appears on all tickets, receipts, etc. for that trip. The conductor accesses different menus on the ETM to issue tickets, select the route, update the source location, and so on. The ETM also generates a status report, an end-of-shift report, and a fare collection report, which can all be used for future audits. The menus in the ETM also allows the operator to check and verify advanced reservations on the route. Describe how this electronic ticketing system works, stating your assumptions. Explain how the operator generates unique trip reports and verifies advanced reservations on the trip.
