Frequency, nature and causes of vehicle encroachments on medians of divided highways were investigated to obtain information needed in establishing traffic safety criteria for median width and cross section design; effects of width and cross section, traffic volume, roadway alignment, weather, roadside signs, grade separation structures and other features of highway and driving environment were considered; relationships between traffic volume and frequency and nature of vehicle encroachments on medians are presented; recommendations include minimum design requirements for safe stopping or control of vehicles in median.
