Abstract
Surveys were carried out in Italy concerning journeys over two stretches of road, where there were clear alternatives between paying to travel on the autostrada or travelling free on a parallel all-purpose road. Origin-destination surveys were carried out at sites on both roads near Rome and Milan and journey time surveys were made over the ordinary roads. A logic analysis was carried out on the choice of route based on the time and cost differences. Journeys were divided into these in the course of work, those to and from work, and other journeys- Limited data were collected on income.
