  • Computational Fluid Dynamics Investigation of High Mast Illumination Poles Influence of Light Fixtures
    Computational Fluid Dynamics Investigation of High Mast Illumination Poles: Influence of Light Fixtures
    Junge, Briceson ;
    Bennett, Caroline
    2026-01-01 | PDF
    High Mast Illumination Poles (HMIPs) are lighting towers that are taller than 55 ft (16.8 m) and are typically located along highways and rest stops. In March 2019, a wind event, referred to as a “bomb cyclone,” caused several HMIPs in Kansas to excite and experience large-amplitude deflections on the order of several feet called “lock-in” behavior ...
  • Effectiveness of Automated Speed Enforcement in School Zones and Guidance for Continuous Usage in Georgia
