This paper focuses on how congestion problems are prevented and managed by the Autostrade SpA company in Italy, which runs the world's largest and busiest toll motorway network, with about 2800km of routes and 580 million users in 1992. Although designed for long-distance travel, the Autostrade network has become more and more involved in urban problems near the main Italian conurbations, and especially in peak period congestion with blocking of the main access roads to cities. Measures applied by Autostrade to reduce congestion phenomena and their effects include: (1) methods for forecasting and estimating the critical state of traffic; (2) measures involving road structures; (3) measures involving toll station structures; (4) automation of toll collection; (5) the Telepass 'electronic money' system, which allows automatic toll collection without vehicles having to stop at toll gates. Toll automation seems to be the most effective method of reducing the main critical states, without reducing mobility levels, because of its great success among users and the remarkable decrease in operating costs that it brings. Autostrade intends to extend the use of Telepass, and has an ambitious project for more extensive integration of urban mobility in its inter-urban and motorway network.
