ABSTRACT

Telecommunications contribute towards the enhancement of transportation networks by increasing the efficiency, safety and attractiveness of different transport modes. Throughout history ‘transportation has always been in the vanguard of new communications applications, because control messages must exceed the speed of the transport itself for effective adjustment to delays, crises and accidents’ (Boettinger, 1989; 288). Transportation in all its forms is controlled by telephone and data lines to dispatch and control traffic. Improvements in these control systems have important implications for increasing the effective capacity and reducing the cost of transportation networks.
