Point Closure

A point closure is another term for a modal filter.

However, 'modal filter' is the recommended term, because these measures do not actually 'close' the street to people walking and cycling, they only prevent motor traffic passing through a specific point, or from driving through an area. 'Closure' is a car-centric term in this context, and indeed inaccurate as in almost all cases motor vehicle access will still be retained.
