Real time information is information that is accurate at the time of production, but when viewed will be inaccurate, especially for an upcoming event.
An example would be when booking a holiday online, and you are presented with an up to date form for seats of the plane, or indeed the number of rooms left in a certain hotel. This may be up to date when it’s sent for you to view, but once you’ve received it, may be inaccurate.
This is shown below with map indicating the flight path and destination of planes in middle east. If we were to search a certain plane, and see its regarded as ‘on time’ this may be true when its sent, however when we read it may be inaccurate and regarded as ‘delayed’, showing that real time information can change at any time.
Real time information could be used to plan a journey online, with like I said planes being just one way it’s used for. This could range from buses, trains to the underground service.
Here’s an example of me planning a route from my home to Tottenham court road, using real time information to track buses, trains and coaches.

2. Take autocar bus service to Judd School, Tonbridge. Leave at 8:25
3. Walk to brook street, opposite Judd School, and take a new enterprise coach towards trench road. Leave at 8:31
4. Arrive at Tonbridge town centre and walk to Tonbridge rail station. Arriving at rail station for the 8:44 departure.
5.Take south-eastern towards London Cannon Street, 38 min journey. Arrive there at 9:22.
6. Walk to London bridge underground station, taking 7 minutes and therefore arriving at 9:29
7. Take the underground to jubilee’s station, in 1 4 minute journey. Arrive at 9:33.
8. Do a 6 minute walk to Waterloo Station, Arriving at 9:39.
