Collisions at grade crossings are often attributed to driver failure to detect warnings, to comprehend their meaning, or to react appropriately. One of the solutions to tackling these problems is the development of various visual signs. We designed three types of visual warnings at virtual grade crossings: a gate with lights and crossbuck, a gate with a crossbuck, and a crossbuck alone. Study 1 shows that vehicle speeds of 18 participants in the period 20 seconds before approaching the crossing (critical zone) decreased in comparison to the baseline (pre-critical zone) for visual warning type 1, a gate with lights. Additionally, participants, who were exposed to a train early in the scenario, showed more defensive driving behaviors than the other case. In study 2, we considered drivers’ eye movement pattern in the pre-critical and the critical zone for 17 participants. Design applications of warnings in vehicles and on roads and further research directions are discussed.
