    The Functions use information from the Stores of current (real-time) and historic vehicle data, plus schedule details to produce vehicle sharing plans, driver work schedules and vehicle maintenance plans. These Stores are provided with data by Functions responsible for monitoring the Public Transport vehicles and preparing schedules - see previous sections 6.5.3 and 6.5.4 respectively.

    Between each of these Functions there are some Data Flows. A minority of these Data Flows enable the Functions to exchange data with each other. Most of the Data Flows enable the Functions to exchange data with other parts of the Manage Public Transport Operations Area, with other Areas and with the terminators. The Functions and Data Flows are contained in the DFD for Function 4.3 - DFD 4.3.
