Data-Driven Strategies Using Predictive Modeling and Interactive Dashboards

Iowa
Since traffic safety projects often yield varying impacts on safety performance, Iowa DOT established a robust system to track crash histories related to safety projects, which is essential to assess project effectiveness, efficiency, and return on investment. The system is helpful to site identification, safety issue diagnosis, and countermeasure evaluation.

B/C Analysis Using Conflict Detection for Midblock Pedestrian Crossings

Georgia
Georgia DOT used conflict detection to assess pedestrian safety at midblock crossings in Jesup, Georgia, allowing for safety concerns to be assessed in further detail than utilizing crashes alone. Using proactive conflict detection data and reactive observed crash data, pedestrian safety projects can be economically justified and prioritized.
