Simulated median plantings were installed on selected portions of two Chicago expressways to determine whether this means of providing roadway delineation would significantly reduce frequency of vehicle encroachment on median; complete record of encroachments was obtained during winter for comparison with number that occurred during same portion of previous year; findings suggest possibility of substantial improvement in safety of divided highways through development and use of median plantings.
