A barrier is a (or barricade) is a physical measure with the aim to block or impede traffic flows.

Description

A barrier as measure is an intentional obstruction of traffic, irrespective of its mode. A barrier can either by static (in place all the time) or dynamic (able to actively open or close).

Barriers can be labeled hard or soft, depending on the amount of effort it would take to overcome the barrier. This amount of effort can be mode specific; a gravel moat would be very hard to cross by car, but is relatively easy to cross on foot.

Examples

Static barriers

Dynamic barriers
