HIGHWAYS WITH A NARROW MEDIAN-CONNECTICUT

THE FOLLOWING FOUR NARROW MEDIAN CONDITIONS ARE FOUND IN CONNECTICUT: (1) MAJOR STREET THROUGH RESIDENTIAL OR SUBURBAN AREA, (2) MAJOR STREET WITH RIBBON COMMERCIAL DEVELOPMENT, (3) LONG STRUCTURE, AND (4) EXPRESSWAY. SPEED DATA AT THESE MEDIAN CONDITIONS WERE OBTAINED BY USE OF RADAR EQUIPMENT. PLACEMENT STUDIES WERE MADE BY SETTING OFF LINES, FROM THE MEDIAN CURB OUTWARD, AT ONE-FOOT INTERVALS, AND VEHICULAR PERFORMANCE WAS RECORDED BY AN OBSERVER STATIONED AT THE SITE. SPEEDS WERE RECORDED FOR THOSE VEHICLES THAT WERE INCLUDED IN THE PLACEMENT OBSERVATIONS. VEHICLES INCLUDED IN THE SAMPLE WERE THOSE WHICH WERE TRAVELING FREELY AND WERE NOT INFLUENCED BY THE ACTIONS OF OTHER DRIVERS. ACCIDENT EXPERIENCE WAS RECORDED FOR THESE MEDIAN SECTIONS. TRAFFIC DATA AND ACCIDENT EXPERIENCE ARE SHOWN IN TABLES. ACCIDENT RATES COMPARE FAVORABLY WITH STATE-WIDE AVERAGE EXCEPT FOR FATALITIES. THE TWO FATALITIES SHOWN ON THE SHORT SECTION OF THE FREEWAY RESULT IN A LARGE RATE PER HUNDRED MILLION MILES.
