What is the minimum stopping distance from a bus stop on the approach and departure sides?

A bus stop designed to hold a standard 40-foot bus that is located along a road that carries traffic traveling 50 miles per hour needs a 470-foot minimum stopping zone and a 975-foot acceleration zone. The length of these zones vary based on the speed of the traffic.

A road carrying traffic traveling 35 miles per hour only needs a 185-foot stopping zone. Increasing the speed of the bus by only 5 miles an hour to 40 miles per hour necessitates an additional 80 feet to stop. Increasing the speed from 50 to 55 miles an hour requires an additional 125 feet to stop safely.
