PAVEMENT WIDTH STANDARDS FOR RURAL TWO-LANE HIGHWAYS

This report summarizes statistical and economic investigations of traffic accident records from selected Idaho and Washington rural two-lane highways. The primary area of concern is the relationship among construction cost, maintenance cost, and accident costs as related to paved width. Results are compared with the minimum paved widths currently specified by the Idaho Division of Highways (IDH). The only configuration of interest is full width roadway paving, or paving which covers both driving lane and shoulder. Structural section of the shoulder is assumed to be the same as that of the travel lane. /Author/
