Hight Avia

Hight Avia transforms complex traffic signal optimization into an intuitive mobile experience. The application implements Webster's formula—a proven mathematical approach for calculating optimal cycle lengths based on traffic flow patterns—directly on your Android device. Input vehicle-per-minute rates across multiple phases, adjust saturation headway parameters, and receive instant cycle time calculations with phase-by-phase breakdowns.

The queue trace visualization system plots vehicle accumulation across ten-minute intervals for every movement direction at your intersection. Drag your finger across the timeline to inspect queue depth at any specific second. The system color-codes each traffic stream and pedestrian crossing, making it simple to identify bottlenecks and verify that phase allocations match actual demand patterns observed in the field.

Beyond calculation tools, the Cross or Clear quiz module sharpens your understanding of signal phasing conflicts. Each question presents two simultaneous movements with intersection diagrams—you determine whether they're compatible or create collision risks. Score tracking and progressive difficulty levels make this an effective training resource for civil engineering students and junior traffic technicians preparing for certification exams.
