This section talks about the various sources of data available to you and when each is most appropriate to use.
1. Internal sources of secondary data
Depending on the scope of the tasks and your organisational structure, there are vast possibilities to identify internal data sources important for public transport. They may include:
- the accounting department (i.e. costs and incomes)
- timetables and their execution (i.e. punctuality, completion of particular departures/arrivals, frequency, average speed, travel times, volume of vehicle-kilometres and hour-vehicle-kilometres)
- the controlling unit (cleanness, general aesthetics of rolling stock and bus stops, drivers, availability of passenger information)
- sales (volume of sales, their structure, number of reduced fare tickets, etc…)
- fare control (number of passengers checked, number of "free riders"…)
There is also a lot of interesting data in different departments of the city administration, especially the spatial planning department, the traffic and road department, the department responsible for vehicle registration and the department responsible for citizens registration, etc…).
The results of previous marketing research can also offer interesting data, especially as a starting point and/or as a source of comparative data.
