Summary

This report presents the findings of a background survey conducted to assess professional drivers’ opinions and experiences regarding railroad grade crossing safety and traffic control devices. The study was part of a larger pilot project sponsored by the Illinois Department of Transportation to evaluate an advisory on-board vehicle warning system. The primary objective was to gather baseline data on driver perceptions of existing warning devices, hazard recognition, and safety behaviors before the implementation of the new in-vehicle warning technology. The researchers surveyed 752 professional drivers from 34 companies whose vehicles regularly utilized five specific railroad crossings along the Chicago-Metra Milwaukee North line. After data cleaning and consistency checks, responses from 750 drivers were analyzed using statistical methods. The survey instrument collected demographic data, driving habits, and specific opinions on the effectiveness and adequacy of standard warning devices, including crossing gates, flashing lights, clanging bells, train horns, crossbuck signs, and advance warning signs. The analysis was structured in three levels: first-level frequency distributions, second-level group comparisons (e.g., by vehicle type), and third-level subgroup analyses based on multiple response patterns. The results indicated that drivers rated crossing gates as the most effective warning device (average rating of 4.7 out of 5), followed by flashing lights (4.5). Train horns (3.3) and advance warning signs (3.0) received lower effectiveness ratings. Despite these ratings, 74% of drivers believed current crossings were adequately protected, while 22% felt more protection was needed. Approximately 47% of respondents viewed railroad crossings as a significant driving hazard above normal conditions. Driver behavior analysis revealed that 88% looked both ways when crossing, and 33% came to a complete stop. Notably, 21% of drivers admitted to crossing tracks while signals were flashing, with 67% of those citing signal malfunction as the reason. Unsafe driving situations were reported by 5.3% of drivers, primarily caused by other vehicles maneuvering dangerously near the tracks. The study concludes that driver perception of hazard does not correlate with the frequency of crossing or stopping but does influence views on the adequacy of current standards. Drivers who perceived a need for more protection relied more heavily on train horns and advance warning signs. Furthermore, vehicle type influenced perceptions; bus drivers were more likely to believe crossings needed additional protection. These findings provide a critical baseline for evaluating the subsequent on-board warning system, highlighting that while most drivers trust existing devices, a significant minority perceive gaps in safety protection, particularly regarding signal reliability and visual obstructions.

Key finding

Drivers rated crossing gates (4.7/5) and flashing lights (4.5/5) as the most effective warning devices, while 47% perceived crossings as significant hazards and 74% considered current protections adequate.
