Stopping Distances @ 45 mph  (Aetna fire response lane / first-responder corridor)

Design goal — both/and: Apple Road / West Park Place serves as an Aetna fire company response lane. The corridor must support both adequate emergency vehicle speed and reach and safe, protected pedestrian crossings near WPPE. These are not competing goals — proper crossing infrastructure (HAWK signal, protected phase) clears pedestrians before responders arrive and gives drivers predictable stop cues. The table below shows braking requirements at typical response speed; the constraint below shows what the corridor currently provides.

Current corridor constraint: ~200 ft available stopping distance (drive-to-intersection at Apple Rd / West Park Place). At 45 mph response speed, no vehicle in this table can stop in time for an unprotected crossing. A protected signal phase resolves this for pedestrians without impeding response — vehicles proceed on red only when the crossing is clear.

All values assume dry pavement, alert driver, well-maintained brakes. Wet roads roughly double braking distance.
