Potential of remote sensing for traffic applications

The paper deals about the potential of remote sensing for traffic applications. Taxis equipped with digital trunk radio and with satellite positioning transmit their position via the trunk radio network to the taxi despatch centre. The taxi despatch centre uses the information for the disposition of the vehicles. The positioning information of the taxis can be transmitted to generate the traffic position to a server in a traffic management center. The principle of floating car data, helps to generate the traffic data from the consecutive position of taxis. Knowing the position of public transportation modes and operating information enables arrival times to be calculated in advance and thus form the basis of passenger information system.
