Settlements where houses are constructed in a long line along a road or river are called linear villages.
Step-by-step explanation:
Linear village refers to settlement where the houses or buildings are formed in lines which follow a transport route such as a road, river, or canal. There is often a single street with houses on either side of the road. It is also known as chain development. In a situation where linear settlements follow a road, the road predates the settlement.
