Barricade (from the French barrique - 'barrel') is any object or structure that creates a barrier or obstacle to control, block passage or force the flow of traffic in the desired direction. Adopted as a military term, a barricade denotes any improvised field fortification, such as on city streets during urban warfare.
Barricades also include temporary traffic barricades designed with the goal of dissuading passage into a protected or hazardous area or large slabs of cement whose goal is to prevent forcible passage by a vehicle. Stripes on barricades and panel devices slope downward in the direction traffic must travel.[2][3]
There are also pedestrian barricades - sometimes called bike rack barricades for their resemblance to a now obsolete form of bicycle stand, or police barriers. They originated in France approximately 50 years ago and are now used around the world. They were first used in the U.S. 40 years ago by Friedrichs Mfg[4] for New Orleans's Mardi Gras parades.
Anti-vehicle barriers and blast barriers are sturdy barricades that can respectively counter vehicle and bomb attacks.[5]
