Study Highlights
Fourteen of the 15 school districts reported operation- ally meaningful reductions in stop arm violations with First Light’s fully illuminated stop arms. Fourteen of the 15 districts showed a decrease in violation rate (violations per school day of bus operation). One district showed a small increase of 15%. In the other 14 districts, violation reduction rates varied between 14% to 100%, with a me- dian reduction of 60%. One district showed a complete eradication of violations with 100% reduction. Where data was available to analyze special circumstances, the fully illuminated stop arm showed uniformly exceptional performance. For example, of those reporting reductions in violations on 2-lane roads, there was an average of

56% reduction. On multi-lane highways, there was an average of 28% reduction. During low light periods, illegal passings reduced by an average of 73%.
A subset of school districts reported whether their pick-ups/drop-offs occurred during daylight. This was to understand the effectiveness of the technology in low light conditions. Of the nine school districts that reported lighting conditions, seven picked-up and/or dropped-off during low light conditions. 100% of the buses utilizing First Light’s fully illuminated stop arm saw a reduction in violations in low light conditions. In contrast, the comparison buses viewed at these same sites actually showed an increase in violations.

The median reduction in violations observed was 60.2%. By contrast, the comparison buses experienced a median increase of 12.2%, indicating First Light’s Fully Illuminated Stop Arms were 72.4% more effective at preventing stop arm violations.
