EFFECT OF DOTTED EXTENDED LANE LINES ON SINGLE DECELERATION LANES (ABRIDGMENT)

The purpose of this study was to determine the effectiveness of the optimal dotted extension of the right edge line for deceleration lanes. A study was conducted on the effect of dotted lines at both tapered and parallel right, single deceleration lane exits with varying approach and exit ramp geometrics on New Jersey's Interstate system. Data collection procedures included the following tasks: performing before studies, installing extended dotted lane lines, and performing after studies. The study concluded that the dotted extension of a right edge line was more effective in orienting existing traffic sooner into the deceleration lane, single tapered and parallel deceleration lanes. No significant change was noted in zone 3 exits (crossing the painted gore regions) at parallel deceleration lanes. It was also observed that existing vehicles use the shorter deceleration lanes with less variation, because there is less room to maneuver. As a result, the use of dotted lane lines did not have as marked an effect on orienting vehicles into these shorter lanes.
