Why is it important?

This paper highlights the differences between sight distance modelling techniques on highways in terms of safety performance. It advocates 3D sight distance modelling considering landscape features and the use of reliability in geoemtric design.


This article provides insight on the safety implications of reduced sight distance on curves under a new approach. It merges a realisitc 3D sight distance estimation technique and a powerful analysis technique that evaluates the risk of failure in engineering systems.
