Study investigated possibility of determining optimum median opening spacing for four-lane undivided highway using safety (accidents), intensity of roadside development (access) and level of service (travel time) as dependent factors; precise optimum spacing of median openings could not be derived; however, accident rates and level-of-service indices could be predicted for sites studied and can be applied to other sites with similar roadway characteristics; regression model utilizing all location types was generated to predict accidents.
