Summary
This report evaluates the Ticketing Aggressive Cars and Trucks (TACT) program, a media and enforcement initiative implemented by the Pennsylvania State Police and Department of Transportation on Interstate 81 in late 2008. The program was motivated by high fatality rates in crashes involving large trucks and passenger vehicles, aiming to educate drivers on safe driving practices around commercial vehicles through high-visibility enforcement and media campaigns. The study sought to determine if drivers were aware of the campaign and if their behavior changed as a result. The evaluation, conducted by Cambridge Systematics, utilized a quasi-experimental design comparing a test corridor (I-81) with a control corridor (I-80). Due to administrative timing constraints, baseline data could not be collected prior to the media launch, forcing an alternative "after/before" design that extended data collection into February 2009 to measure message retention. The methodology included four data sources: over 5,000 attitudinal surveys administered at driver services facilities, analysis of crash and citation records, more than 40 hours of video observations by unmarked enforcement officers, and reviews of these videos by an expert panel of officers. The findings indicated that 32% of drivers in the test corridor reported hearing about the TACT message, with electronic media having the highest penetration and billboards showing the best message retention. Statistical analysis suggested that approximately 8% of respondents changed their driving behavior based solely on media exposure, though this figure could be as high as 33% given survey instrument limitations. The results mirrored those from a similar pilot in Washington State. However, the enforcement component faced significant challenges; seven months post-implementation, officers struggled to agree on appropriate enforcement actions for observed violations, indicating a lack of uniformity in interpreting TACT-related behaviors. The study concludes that while the media component successfully reached drivers and induced behavioral changes, the enforcement aspect suffered from inconsistent application. The authors identify 11 procedural findings, primarily criticizing the rushed timeline that prevented proper evaluation framework establishment. They recommend that future initiatives allow sufficient lead time for staffing, coordination, and baseline data collection. Additionally, the report highlights biases in the survey instrument, which skewed results toward older drivers, and suggests broader data collection mechanisms and improved survey designs for future safety initiatives.
Key finding
Approximately 8 percent of surveyed drivers reported changing their driving behavior due to the TACT media campaign, while 32 percent of drivers were aware of the initiative.
