Rumble strips are patterned grooves or raised elements placed across or along a road surface. When a vehicle drives over them, they produce noise and vibration that alert the driver. They are commonly used near lane edges, medians, intersections, or approaching hazards to reduce unintended lane departures.
What is the US nickname for a carpool lane?
In the United States, a lane reserved for vehicles carrying multiple occupants is commonly called an HOV lane, meaning High-Occupancy Vehicle lane. It is also widely known as a carpool lane. The lane is often marked with a white diamond symbol on signs and pavement.
What is a Barnes Dance crossing?
A Barnes Dance is a pedestrian scramble that stops motor traffic in every direction at an intersection. During the pedestrian phase, people can cross the road, sometimes including diagonally, while vehicles remain stopped. The name honors Henry Barnes, a US traffic engineer associated with promoting the design.
What is a pedestrian countdown signal?
A pedestrian countdown signal displays the number of seconds remaining in a crossing phase, usually while the flashing or clearance interval is active.
