Preventing End-of-Queue Crashes With Proven Technology
When roadworks slow traffic, queues form fast. A distracted driver approaching at speed often doesn’t react in time, leading to an end-of-queue (EOQ) crash. These collisions are among the most common and dangerous incidents in Australian work zones.
A major study led by Deakin University and iMOVE CRC found that EOQ crashes account for around 40% of all work zone incidents in NSW. Their research trialled 25 treatments across 13 sites, and the results were clear: advance warning systems work.
The eSERIES Advantage
ARROWES is leading the way with a proven solution: the eSERIES, integrating our eSTOP portable traffic light with the eSASb Speed Awareness Sign.
- When the light turns red, the eSASb, positioned up to 400 metres upstream, automatically alerts approaching drivers that a queue is forming.
- The sign also provides live speed feedback, encouraging drivers to slow earlier and approach more safely.
Evidence That It Works
The Deakin/iMOVE study identified eSERIES treatments as among the most effective tested:
- Very large reductions in excess speed (>5 km/h).
- Reduced probability of speeding by more than 10%.
- Decreased rear-end crash risk, based on near-miss analysis.
- Positive driver feedback, with most wanting the system used more widely
Why This Matters
- Lives protected: Workers and motorists are less exposed to high-impact rear-end crashes.
- Proven locally: These results come from Australian worksites, not just theory.
- Future-ready: ARROWES has already delivered a built, deployable solution that can be scaled today.
End-of-queue crashes are predictable and preventable. With eSTOP + eSASb integration, ARROWES is not just talking about safety innovation; we are delivering it in the field.
Because every second of warning can be the difference between a safe stop and a serious crash.
