Safety Data and Analysis Noteworthy Practices

Illinois DOT Provides Local Public Agencies with Assistance on the Use of Safety Data
Through the use of improved safety data sharing abilities, Illinois has improved its project submittal process; safety projects are submitted more quickly than ever before. IDOT's technical assistance and data-sharing efforts allow the agency to support Illinois' counties as they program projects to improve the safety of local roads in the State.

Louisiana Department of Transportation and Development Provides Reduced Data-collection Costs to Local Agencies While Ensuring Data Consistency
In an attempt to streamline the data collection process and reduce costs, Louisiana Department of Transportation and Development  has encouraged local agencies and metropolitan planning organizations (MPOs) to join a larger statewide data collection effort.

Integrating Safety Analysis in Project Development in Louisiana
Through this effort, LADOTD increased safety awareness throughout the Department and with local agencies. Cost savings, though difficult to precisely quantify, improved the State's ability to use available funding for safety improvement in multiple contexts, and resulted in successful implementation of low-cost alternatives, and reduced crash risk during construction.

Michigan’s Roadsoft Program Enables Local Agencies to Collect and Maintain Data, while Preserving Local Ownership and Control

Michigan Undertakes Initiatives to Encourage a Data-Driven Approach to Local Roadway Safety
These initiatives help bolster the State's multifaceted roadway safety program by providing local agencies with meaningful, timely access to crash data, as well as tools for data analysis and training to manage their safety processes.

Ohio, with Stakeholder Input, Develops Consistent Mapping and Data Standards for State and Local Roads

UDOT's Advanced Data Collection Methods Result in Better Quality of Roadway/Asset Data and Improved Internal Management of Data
The data collection effort performed by UDOT was a first-of-its-kind, surveying the entire state roadway network and obtaining a wide set of data elements.  LiDAR (a term that combines "light" and "radar") was used by the selected vendor to collect a variety of asset data. The LiDAR technology creates a three dimensional model of the assets scanned along the roadway, and is performed in a single pass at highway speeds.

Interoffice Safety Groups at Washington State DOT Use Quantitative Data Evaluation to Determine Strategies Across the "4Es"
Washington State Department of Transportation  relies upon these three cross-cutting groups to ensure that expert judgment guides the transportation planning and project selection process in Washington State. These three groups play an important role in identifying the State’s safety needs and providing guidance to WSDOT regional offices in support of safety project selection.
