Summary

This study evaluates the long-term effectiveness of a photo enforcement-based driver education program at the East Princeton Street highway-rail grade crossing in Orlando, Florida. The research was motivated by the high incidence of collisions at crossings equipped with active warning devices, which accounted for approximately 70% of all grade crossing incidents in 2017. The City of Orlando implemented a pilot program using photo enforcement technology not to issue fines, but to send warning notices and educational materials to vehicle owners who violated active warning devices. The primary objective was to determine if this educational intervention sustained its ability to reduce driver violations 20 months after implementation, compared to baseline data and short-term results. The Volpe Center, under the Federal Railroad Administration, employed a before-and-after experimental design. Data collection occurred during three phases: a 14-day baseline period (April 2016), a short-term evaluation eight months post-implementation (April 2017), and a long-term evaluation 20 months post-implementation (April 2018). The automated photo enforcement system monitored westbound traffic, capturing violations where vehicles entered the crossing during gate descent (Type II). Although signage was installed for both directions, only westbound traffic was enforced. Researchers coded four types of violations based on the phase of the warning device activation. Additionally, the study analyzed survey responses from violators who received warning notices to understand human factors contributing to non-compliance. The results demonstrated that the program remained effective in the long term. The average hourly rate of violations per activation decreased from 6.0296 in the baseline phase to 4.9916 in the long-term phase, representing a 17.2% reduction. This improvement was consistent across all violation types; for instance, Type I violations (entering during flashing lights) decreased by 10.7%, and Type IV violations (entering during gate ascent) decreased by 20.3%. The reduction in the long-term phase (17.2%) was slightly higher than the short-term reduction (15.4%). Survey data from 333 respondents revealed that 53% did not see the photo enforcement signage, and 42% cited failure to see activated signals as the reason for their violation. The study concludes that photo enforcement-based education is a viable strategy for improving driver compliance at highway-rail grade crossings, with benefits persisting at least 20 months after implementation. The sustained reduction in violation rates suggests that the educational component, rather than punitive fines, effectively modifies driver behavior. These findings support the potential for broader adoption of such programs to mitigate the risk of train-vehicle collisions at active crossings.

Key finding

The average hourly rate of grade crossing warning device violations decreased by 17.2 percent 20 months after the implementation of the photo enforcement-based education program.
