This study on the recognition of road types within built-up areas used video recordings of forty eight systematically chosen road stretches. In the first part of the study, these recordings were judged by nine subjects, using the personal construct method. This part produced a number of rating scales representative for these nine subjects. In the second part of the study thirty nine subjects judged the road stretches on these rating scales. Analyses of these judgments show that road users as a group discriminate more types of roads than provided by the official categorization. The types are strongly related to the judged safe speeds on the stretches. The latter were higher compared to the speeds prescribed by the official categories and were mainly related to the judged manoeuvring effort required for following the road.
