The closest taxi driver then radios back to confirm that they want the job. The operator then gives the details of the job, including the address. The problems with this system include: 1.

Interference on the radio can sometimes make the instructions unclear 2. Taxis occasionally go to the wrong address or arrive at the wrong time 3. Taxis sometimes get lost and arrive late Many taxi firms now have a new system, which make use of global positioning. This system enable the taxi office to pinpoint a taxi that is free and nearest to the caller.

Using ICT to find you way: using satellite positioning systems Satellite positioning systems are able to locate the position of any object on the Earth’s surface. Theses systems can be used to locate the position of an aircraft or ship or even a person. Some cars are equipped with a similar system so that the driver can locate their position on a map on a small screen inside the car.

The driver can then use the system to obtain directions to their destination. Some systems give the directions (turn left, turn right, etc.) on a screen whereas others give the driver verbal direction as they approach junctions and turns. Hand-held satellite positioning systems are available and are used by people walking in isolated regions such as mountains or deserts. Satellite positioning systems use information from a host of satellites to determine where the driver is located, and a small computer is used to provide the maps. As well as giving details of roads, the system can also provide information on the locations of airports, banks, hotels, restaurants, etc.
