The relevant speeds are the 85th percentile speeds measured on the existing road, or in the case of new roads, the proposed design speed. These are set out in the Table 1. DMRB visibility distances apply to roads which

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. Perform sight distance analysis.
