EFFECT OF LANE WIDTH ON TRAFFIC OPERATION

A COMPARISON OF TRAFFIC VOLUME, SPEED, HEADWAYS AND DENSITY ON TWO BRIDGES ACROSS THE DELAWARE RIVER OF COMPARABLE OVERALL WIDTH INDICATED THAT THE SEVEN 11-FOOT, 3-INCH LANES OF THE WALT WHITMAN BRIDGE CARRIED 20% MORE TRAFFIC PER LANE THAN THE EIGHT 9-FOOT, 8 3/4-INCH LANES OF THE BENJAMIN FRANKLIN BRIDGE. STOP-MOTION PICTURES TAKEN AT ONE-SECOND INTERVALS FROM THE TOWERS OF EACH BRIDGE PERMITTED MECHANICAL CALCULATION OF VOLUME, SPEEDS AND OTHER OPERATING CHARACTERISTICS WHICH INDICATED SIGNIFICANT IMPROVEMENTS IN TRAFFIC CAPACITY. LATERAL PLACEMENT, AVERAGE OPERATING SPEEDS AND HEADWAYS FOR THE WIDER LANES WERE COMPARED WITH THE ONE-AND-ONE-HALF-FOOT NARROWER LANES OF THE BENJAMIN FRANKLIN BRIDGE. /AUTHOR/
