In a road work zone the traffic control layout is the only thing standing between the crew and live traffic. Taper length, device spacing and advance warning are engineered figures derived from approach speed, not preferences — a short taper gives drivers insufficient distance to merge, which is precisely how a vehicle enters the work space. High-visibility apparel and a shadow vehicle are the last layers when that happens anyway.
The steps ChatterFix schedules for this PM. Every step is a checkable item on the work order — a technician can speak their way through it without touching a keyboard.

Setups get shortened for convenience on 'quick' jobs, which are exactly the jobs where the crew is exposed with the least protection. Devices lose retroreflectivity and become nearly invisible at night while still looking acceptable in daylight. Struck-by remains the leading cause of death in roadway work, and it is almost always a setup failure rather than a driver anomaly.
Verify every setup at deployment, with a documented programme audit monthly. Any change in speed limit, road geometry or shift into night work changes the required layout — the plan is derived from conditions, not copied from the last job.
This procedure — and every other PM for your industry — is already built into ChatterFix. Pick your industry and it lands on the right equipment, on the right interval, in about three minutes.
