1 Increasing Nighttime Seatbelt Usage Rates: An Evaluation of Enforcement, Education, and Outreach Strategies Shashi Nambisan Jerry Everett, Matt Cate Center for Transportation Research University of Tennessee, Knoxville Tennessee Section ITE Spring 2015 Meeting Kingsport, TN May 21, 2015

2 Project Overview 3-year CDC funded research project Additional support from TN GHSO Target age group: year olds Study area: 5 east TN counties + control county Community support/participation is key Lessons learned to be shared across US 2

3 Study Setting and Potential Observation Sites 3

4 Seatbelts Save Lives Use of seatbelts save > 15,000 annually Statewide ave. daytime SB use rate in TN ~88 % Nighttime seatbelt usage rate ~ 15 % lower Studies show that about half of TN highway traffic crash fatalities are unbuckled => 50% of the traffic fatalities come from 12% of our population 4

5 TN Seat Belt Usage % 90% 85% 80% 75% 70% Usage Rate 65% 60% 55% 50% 45% 40% 35% All Vehicles Cars Pickup Trucks Vans SUVs Year 5

6 Average: TN vs National Tennessee National Avg

7 CTR Survey Research Findings Seat belt usage tends to be lower for those With a high school education or less (vs. college) Who are black or Asian (vs. Caucasian) Who are between the ages of Who earn less than $30K/year Who drive pick up trucks 7

8 Develop, implement, and evaluate a pilot program which o combines increased targeted nighttime seatbelt use enforcement and o broad community based outreach & education (O&E) activities including paid media campaigns Assess how such interventions o affect nighttime seatbelt usage rates and impaired driving o are related to socio-demographic, spatial, and temporal characteristics o affect other traffic violations Project Aims o are related to other societal indicators of public safety o influence morbidity and mortality due to such crashes 8

14 Phased approach for targeted nighttime enforcement activities and O&E efforts o Coordinate schedules for broadcast and social media based O&E efforts with existing efforts Targeted enforcement activities similar to those for DUI enforcement o saturation patrols o check points Intervention and Evaluation Typical timeline for enforcement activities and O&E intervention 15
