The route survey serves as the validation of a proposed route ensuring the safety of all involved while the load is being transported . A vehicle (in most cases a pilot car, also known as an escort company) must travel the exact route proposed to perform a route survey.
Is a route survey used for highways?
Route Surveying is a branch of Civil Engineering dealing with the design and construction of linear works, such as roads, highways and pipelines. ... Results of these surveys are used to prepare detailed plan and profile base maps of proposed roadways.

What is topographical in surveying?
A topographic survey locates all surface features of a property, and depicts all natural features and elevations . In essence it is a 3-dimensional map of a 3-dimensional property showing all natural and man-made features and improvements.
