The principle is to make use of "unused capacity" in one direction to carry traffic in the other direction. The HOV Diamond Symbols / HOV Lanes Road markings for HOV lanes are marked on the road as a diamond symbol Reversible lane conceptshave complex operating strategiesnew to most travelers, Law enforcement coordination to ensure driver compliance and address potential violations, Static and electronic signs to communicate reversible lane access status to drivers, Barrier equipment, including gates and/or barrier-moving machines, Traffic and/or incident detection to triggerlanereversals and lane closures, Software to determinewhen lane reversals should occurand activate electronic signs and any field devices, Closed-circuit television (CCTV) and redundant monitoring components to verify that the system is operating safely, Regular testing and validation of the dynamic lane assignment system to confirm that all components are operating reliably and safely, Traffic engineers to place signs and other field elements, establish proper messaging, monitor its effectiveness, and make modifications to the system, Traffic management center operators to operate and monitor the reversible lanes system, For non-automated systems and those requiring additional safety redundancies, ground crews to perform regular safety sweeps of the express lanes prior to activating the reversal. Phase 1 also concluded that the lane utilization of the reversible lane is less than the utilization of the normal through lanes Main findings of the report focussed on comparing costs, time from design to operation and environmental issues. [6] For routes with moderate traffic, other movements involve downgrading four-lane undivided streets to three-lane streets with a turn-only center lane. Take a balloon and blow it.
