AB  - The continuing global mission for safer roads has led to many important ways for safety evaluation
and improvement especially for two-lane rural roads. Available visibility is one element that has the combined
function of speed, driver characteristics and the driving environment. Since, most fatal accidents occur at
relatively high speeds, the driver's ability to accommodate and control successive variations of available
visibility along the road is a very relevant safety component. This study is positioned to present the possibility
of considering these variations directly, especially when the visibility values can easily be obtained. It is shown
that road sections with high inconsistent visibility differentials have the highest possibility of crashes. The
existing relationship between crashes and visibility along two-lane rural highways is upheld. Some technical
recommendations and room for further research are proposed and advised.
