What is it about?

Discussion on the use of diverse elevation models to recreate the road and its roadsides in 3D sight distance estimation of in-service highways. The elevation models were derived from airborne and terrestrial LiDAR data and may comprise landscape features affecting sight distance on highways.

Why is it important?

LiDAR data are a valuable source for highway construction and management. Hence the capabilities of this technology must be researched, in particular its application to sight distance and, therefore, traffic safety.


This study highlights the difficulties involved in using a cloud point to create a Digital elevation model to shape a piece of alnd and the landscape features.
