What Type of Crash Can We Expect? Designing for Safety at Common Traffic Control Devices

Lowering crash severity is a critical priority for transportation professionals and all those in the transportation community who are actively adopting Vision Zero. With the goal of reaching zero fatality and serious injury crashes, the need to better understand the factors related to severe cases becomes essential. Crash severity is highly shaped by the crash type, or manner of collision. For example, the odds of being fatally injured in a crash greatly increases for head-on and rollover crashes. Severity has been found to be highest for head-on collisions, followed by angle crashes, and lower for rear end and sideswipe crashes. Given this relationship between crash type and severity, it is critical that transportation professionals understand the likelihood of specific crash types to occur at various traffic control devices. A large-scale study in the United States revealing this relationship has yet to exist in literature. This information will guide future decision-making, guiding transportation practitioners to implement the most critical countermeasures to achieve the highest level of safety. This article aims to investigate the probability of various crash types at different traffic control devices. The results allow transportation professionals to create informed decisions in their crash countermeasure selection process at various traffic control devices.
