Abstract:

Road delineation treatments provide drivers with visual cues, which can enhance vehicle navigation and control. However, they can lead to undesirable effects and increase risk, due to behavioural adaptation or if not properly designed or installed. In recent years, the use of internally-illuminated pavement markers for road delineation has become increasingly popular. INtelligent Renewable Optical ADvisory System (INROADS) is a research and development cooperation project carried out within the 7th Framework Programme of the European Commission, dedicated to the development of intelligent road lighting applications. Within that framework, an Active Lane Delineation (ALD) application is being developed: internally-illuminated pavement markers are automatically turned on to outline the lane and road edges as a vehicle approaches to and passes through curves, and are turned off otherwise. In this talk, following an introduction on INROADS, delineation treatments and country road crashes, I will present the ALD prototype designed at The French Institute of Sciences and Technology for Transport, Development and Networks (IFSTTAR) for INROADS and a simulator experiment designed (at IFSTTAR) to shed some light on its relative effectiveness. The experiment compared night-time driving on a country road in the presence of the ALD application to driving on an unlit road and to a road illuminated by conventional road luminaries, on a number of objective and subjective criteria. At a subjective level, the participants perceived driving in the unlit condition, as less safe, less comfortable and allowing less control than in both the ALD and luminaries conditions, but there were no significant differences between these latter conditions. However, all in all the behavioral results demonstrated safer performance measures of vehicle trajectory, speed and control, in the ALD condition relative to both the unlit condition and the luminaries condition. Human factors considerations on the design of internally-illuminated pavement markers for road delineation will be discussed, focusing on the cost-benefit trade-off of the illumination effects on driver perception and driving behavior.
