Cyclists are vulnerable, and particularly older cyclists have an increased risk of crashing. Therefore, Frank Westerhuis and his colleagues from the traffic psychology group investigated countermeasures to increase cyclists’ safety. This blog post reveals whether they were succesful in achieving this by using illusionary objects next to the cycle path.
Blood Alcohol Concentration (BAC) of bicyclists was assessed with a breathalyser on nights out. An expected increase in percentage cyclists with a BAC above zero over the course of the night was found, and after midnight the proportion cyclists with alcohol in their blood rose to 90%, with an average BAC above 0.8‰.
