WebA sight distance study at an uncontrolled intersection includes four key steps: 1. Determine the minimum recommended sight distance. 2. Obtain or construct sighting and target rods. 3. Measure current sight distances and record observations. 4. … WebSight Distance (Obstruction Removal) Insufficient sight distance and limited forward visibility can adversely affect safety and increases the risk of a collision by reducing reaction times and stopping distances. Adequate sight distance provides drivers with sufficient time to identify and appropriately react to all elements of the road ...
