While many studies have focused on driver distractions such as cell-phone use, the impact of infrastructure elements on distraction and the extent to which they may cause distraction has not been well studied. Examples include objects that are unusual (such as aesthetic bridges) or confusing (signage or markings) or that require an unusual amount of time to locate (like a specific wayfinding sign among multiple roadside objects).
The TRB Behavioral Traffic Safety Cooperative Research Program's BTSCRP Web-Only Document 1: Influence of Infrastructure Design on Distracted Driving provides an opportunity to develop a better understanding of the interaction between the built environment and driver distraction.
