Abstract
Analysing the distance visible to a driver on a highway is important for traffic
safety, especially in manoeuvres such as emergency stops, when passing
another vehicle, or when vehicles cross at intersections. Software that
calculates highway distances visible to a driver has been developed. This
software is supported by a Geographic Information System (GIS) and can use a
trajectory defined by points obtained with a GNSS receiver instead of relying on
project information. The software includes specific tools for studying
shortcomings in 3D alignment, mainly divings. In this article, the software and its
application to a case study are presented. The results are compared with those
obtained using an existing validated procedure
