title: Drivers' behaviour at roundabouts in Riyadh.
abstract: As is the case in many cities, roundabouts are used extensively in Riyadh. However, instead of improving safety, driving through roundabouts in Riyadh can be a dangerous experience as many drivers do not follow regulations. Unfortunately, no official statistics exist on accidents or violations at roundabouts and no studies have been done to assess this problem. A field study to collect data on drivers' behaviour at five roundabouts in Riyadh was done and a questionnaire was randomly distributed to drivers to explore this issue. Results showed that the percentage of drivers breaching at least one traffic regulation is approximately 90% of all drivers driving through these roundabouts, with leaving without flashing and entering the roundabout without giving way being the most frequent violation types. Questionnaire results from 384 respondents showed that there is a lack of information among most drivers on roundabout driving regulations and that driver training and licensing process does not include enough information related to this matter. Finally, practical suggestions as how to tackle this issue in terms of education, training and policing are given.
