The Relationship Between Traffic Locus of Control and Driver Space

This study investigated the relationship between traffic specific Locus of Control (T-LOC) and Driver Space Preference. Two video clips were created of an actual driving event filmed through the windshield of one car approaching another car and also simultaneously through the rearview mirror of the car being approached from behind. After completing demographic and personality questionnaires (including T-LOC), participants watched both videos (using a counterbalance for order) and used the “stop method” for each video to indicate the distance they would normally prefer in that situation if they were the driver of that vehicle. These represented both front and rear driver space preference. Regression analyses revealed that front driver space preference was predicted by Internal T-LOC (i.e. active space that is controllable by the driver) indicating those who believe they have control over their driving outcomes prefer to place greater distance between themselves and lead vehicles. In contrast rear driver space was predicted by External T-LOC (i.e. passive space controlled by others) indicating that those who are more prone to believe others control driving space desired greater distance between themselves and trailing vehicles. Given that spacing between vehicles is related to collisions, as well as perceptions, judgments and interactions between drivers, understanding the predictors of space preference is important for traffic safety.
