Summary

This report evaluates the effectiveness of a photo enforcement-based driver education program at the East Princeton Street highway-rail grade crossing in Orlando, Florida. Sponsored by the Federal Railroad Administration (FRA) and conducted by the Volpe Center, the study addresses the persistent safety issue of motorists violating active warning devices at grade crossings. Despite the presence of gates and flashing lights, a significant portion of grade crossing incidents occur at protected sites. The primary objective was to determine if issuing warning notices—rather than fines—to vehicle owners who violated warning devices could reduce violation rates and improve compliance, thereby lowering the risk of train-vehicle collisions. The researchers employed a before-and-after experimental design. Data collection occurred during two 14-day periods: April 14–27, 2016, prior to the program’s implementation, and April 13–26, 2017, approximately eight months after the system became operational. The intervention involved installing an automated photo enforcement system that detected vehicles entering the crossing during the gate descent phase (Type II violations). The City of Orlando issued warning notices accompanied by educational materials and surveys to registered owners of violating vehicles. Video data collected by the Volpe Center allowed for the coding of four violation types: entering during flashing lights (Type I), descending gates (Type II), horizontal gates (Type III), and ascending gates (Type IV). Additionally, the study analyzed 1,320 violation notices issued between August 2016 and September 2017 to assess demographic factors and driver self-reported behaviors. The results demonstrated a statistically significant improvement in driver compliance. The overall average hourly violation rate per activation decreased by 15.4 percent, dropping from 6.0296 in the pre-test period to 5.1004 in the post-test period. All four violation types saw reductions: Type I decreased by 13.9 percent, Type II by 13.5 percent, Type IV by 16.1 percent, and Type III violations were eliminated entirely (100 percent reduction). Analysis of the violation notices revealed that male drivers were more likely to commit violations relative to their license share, while female drivers were more likely to violate relative to miles traveled. Survey responses from 133 violators indicated that 60 percent did not see the photo enforcement signage, and 27 percent claimed they did not see the activated crossing signals, highlighting visibility and awareness as key human factors. The study concludes that photo enforcement-based education is an effective strategy for reducing grade crossing violations. By leveraging automated detection and educational outreach rather than punitive fines, the program successfully altered driver behavior across all violation categories. The findings suggest that such programs can serve as a viable safety mitigation tool for highway-rail grade crossings, particularly where active warning devices are already present but compliance remains low. The elimination of Type III violations and the significant drop in other categories underscore the potential for this approach to enhance rail safety and reduce the likelihood of catastrophic incidents.

Key finding
