This report reviews how human factors are explicitly or implicitly considered in the current road design standards of the following countries : Australia, Canada, China, Czech Republic, France, Hungary, Japan, the Netherlands and Portugal.
The report focuses on design features as they relate to the spatial perception of the driver. It covers in particular :
- the need for the driver to anticipate any critical point;
- management of the field of view to ensure appropriate speed and lane tracking;
- the human factors demands to pre-program the driver's behaviour.
For the different criteria and factors, the report identifies best practices and provides recommandations for the missing links such as : the optical density of the field of view ; transition zones ; fixation objects in the lateral road side environment ; depth of the field of view.
