The signal from the vehicle is used to locate it along its route. A computer system uses this information to predict how long will the journey be.

There are RTI signs currently located in the local bus services all around London.

Countdown is an electronic information display system that gives people waiting at bus stops real-time information on bus arrival times.

The increasing use of information technology and electronic communications has raised travellers’

Real time information displays at bus stops and stations are highly valued by passengers as they provide reassurance on the time they will have to wait for their next bus. Displays at bus stops along a route can display both the predicted and scheduled arrival times, as well as provide supplementary messages to inform passengers of exceptional delays or service information. Such systems usually base their predictions on the actual locations of vehicles combined with timetable database.

For example: if we want to look up for the train to go Kingston station this afternoon, in the network rail website we can find a number of information, by means of postcode or the name of the station, subsequently we can also obtain the entire information, of arriving and departing of the train. We can also find information’s about what route we want to take for it has shown the full map view of the particular place starting from the station. It has also given us information about the ticket fare and also includes various information, such as: ticket fare for pick up and off seasons, means to buy the ticket online. All the way through network rails website can get information about the tram services that goes around other big cities in the UK such as Birmingham, black pool, Croydon, Manchester, Nottingham and Sheffield. Further more, if we need a fast journey it also provides information about the tube services in different areas around London such as: , ,and metro.

Peer Reviews

Here's what a star student thought of this essay

1st of Mar 2012

Quality of writing

The report states the term 'RTI' and gives a detailed description. This is quite good, as this shows a clear understanding of this technical term. The report is quite presentable, with three images within the report. This allows the examine to visualize the report, which is useful and effective.

Level of analysis

The report states how a display unit can update, using either a satellite or radio signal. Although doesn't explain, why this is useful. The report could include 'The benefit of using either the satellite/radio, is that a person is able to update the situation quickly within their office. As there would be able to gather information on how the system is coping, and if the train is late, this information can be received quickly in the office, and displayed using one of two signals quite effectively'.

Response to question

In summary, the report is quite basic. The report does describe how data is is updated in real time using a number of methods. However the report is lacking detail and case studies which would link the background research to an commercial environment. The report states a user is able to use the internet to find information regrading the service on that day. However the report doesn't give any examples/case studies of websites which pride this service. For high marks, the user could undertake this process, and show a website which provides the information.
