Innovation of the Month:
Data-Driven Safety Analysis
Nearly half of the Nation’s traffic fatalities occur on local roads, creating a need for local agencies to invest their limited safety dollars strategically. To help local agencies plan effective investments, the Every Day Counts round four (EDC-4) deployment team on data-driven safety analysis (DDSA) is advancing locally targeted initiatives.
One focus of the EDC-4 DDSA team is local road safety plans (LRSPs), which identify, analyze, and prioritize safety improvements and strategies for local roads. The team partnered with the National Association of County Engineers on a pilot project to help 25 counties in California, Colorado, Florida, Nevada, Ohio, and Wisconsin develop LRSPs tailored to local issues and needs.
The pilot provides agencies with a blended learning experience that includes technical assistance, a series of webinars, and a hands-on workshop to help participants develop a draft LRSP. As counties in a State develop plans, they share their experience with peers in other counties and encourage them to invest time in developing their own plans.

Historic Bridge Move Reduces Traffic Impact in Oklahoma
In a first for the State, the Oklahoma Department of Transportation (ODOT) used self-propelled modular transporters—computer-controlled vehicles that carry large structures and position them precisely—to install two railroad bridge spans over I-235 in Oklahoma City over a weekend. Using accelerated bridge construction to build the bridge truss structures near the interstate and move them into place greatly reduced the impact on traffic, requiring a road closure from Friday night to Monday morning rather than for several months if traditional construction methods were used. ODOT used DOT and railroad coordination best practices on the project, including working with one point of contact at BNSF Railway, conducting regular meetings on project status, and creating a flow chart for the document submission and approval process to enhance efficiency. The bridge is part of a reconstruction and widening project on I-235. For information, contact Souzan Bahavar of the FHWA Oklahoma Division.
