Predictive Safety Analysis Aids in Selection of New Design for an Outdated Interchange in Ohio
FHWA has developed a series of instructional guides illustrating how Data-Driven Safety Analysis can be incorporated and applied in common transportation tasks and processes, with the goal of helping agencies assess future safety performance and make more-informed decisions.
Incorporating DDSA into Traffic Impact Analyses
Incorporating DDSA in Road Diets
Incorporating DDSA in Intersection Analysis through the use of Intersection Control Evaluation
The following are examples of tools* agencies can use to apply predictive and systemic approaches.
