Definition

A section of a transportation route where its size (for example: narrowing or expansion in width) and/or operating speed is significantly different than in the adjacent sections of the route.

Description

For example, an increase or decrease in the number of lanes in a road. Constrictions along or beside a transportation route may impede the flow of vehicles or people thus resulting in 'choke points'.
