Whitchurch presents Impairment Predictive Model at SAS Conference

October 31, 2019

BATON ROUGE - David Whitchurch, Center for Analytics & Research in Transportation Safety (CARTS) business analytics manager, presented his paper, “Building a Neural Network Scoring Model with JMP and Microsoft SQL Server,” at the 2019 South Central SAS® Users Group Educational Forum held at Louisiana State University.

The paper describes steps taken to create and score a reusable neural network model that predicts alcohol impairment of drivers in motor vehicle crashes. The model is used to estimate the number of drivers whose blood alcohol content (BAC) was greater than or equal to 0.08% at the time of a crash. These estimates are used in analytical tools designed, created and maintained by CARTS. These tools provide support for planning and decision making related to reducing the number of alcohol-involved fatalities and injuries on Louisiana roadways. Stakeholders currently using the tools include the Louisiana Department of Transportation and Development (DOTD), Louisiana State Police, Louisiana Highway Safety Commission, and others. The crash data tools can be found at http://crashdata.lsu.edu.

The 2019 South Central SAS Users Group (SCSUG) Educational Forum was held at the Business Education Complex on the LSU Campus on October 16-19, 2019. Throughout the forum, there were multiple presentations from the SAS Institute, originally presented at the 2019 SAS Global Forum. Twelve back-to-back fifty-minute Hands-On Workshops as well as sessions with presentations by nationally recognized professionals who use SAS in their work. There was also a robotics demonstration using Python through SAS.


The Center for Analytics & Research in Transportation Safety (CARTS) is responsible for collecting, maintaining, integrating, analyzing and distributing crash-related data captured from law enforcement and other agencies throughout the State of Louisiana. CARTS utilizes this data to develop business intelligence (BI) and GIS tools, perform research studies and produce an annual factbook. These tools and publications are used by decision-makers to identify potential problem areas, create countermeasures, set policies, and establish programs to improve the safety of our roadways in Louisiana. CARTS is a center within the E. J. Ourso College of Business at LSU.
