Abstract

This paper presents the results of an experimental trial conducted on a population of 64 road users. 7 Test participants drove a vehicle equipped with GPS on an oval racetrack. The GPS system 8 recorded the position and the speed of the vehicle. The objectives of this study were to analyze1) 9 the correlation between risk and the speed perceived by the drivers, 2) the influence of the 10 geometric layout on the perceived risk, 3) the influence of familiarity with the environment on the 11 perceived risk, 4) the analytical perception of the speed. Test participants were recruited to drive on 12 the test track for a total of 18 laps. The population demographics were identified through a 13 questionnaire. Three different scenarios were used during the experimental trials. The scenarios 14 consisted of different driving instructions given to the drivers, namely 1) the adoption of three 15 vehicle speeds indicated qualitatively (low, medium, high) with no real time information to the 16 driver about the speed, 2) the adoption of three speeds indicated quantitatively with no real time 17 information to the driver about the speed, 3) the adoption of three speeds indicated qualitatively 18 (i.e., using a low, medium and high level of safety) with real time information on the speed to the 19 driver. The study permitted us to identify a correlation between risk perception and drivers’ 20 familiarity with the test track. The test also showed the relationship between speed and perceived 21 risk and the relationship between speed and the geometric layout of the racetrack
