Advanced traveller information systems providing information on route choice, and drivers receiving such information modify their route characteristics accordingly. So far the information transmitted to drivers is mainly related to traffic conditions such as travel time, delay, queue or incident characteristics. A proposed development that could also improve road safety is to enhance on-board advanced traveller information systems with information on the safety level of the alternative routes. It might be the case, that drivers may change their route to follow a safer one. To assess the significance of such an introduction, its impact on driver choices needs to be explored. Hence, the present research investigates driver route choice in relation to three attributes: route distance, travel time and safety level. In order to capture driver choices a questionnaire-based stated preference survey was carried out and discrete choice analysis was performed on the survey results. Analysis results indicated that providing information on route safety influences driver route choice and supporting the development of such a system as a means to improve road safety.
