With the use of dotted extended lines at tapered and parallel single deceleration lanes at right hand freeway exists, a significantly greater proportion of exiting traffic entered the deceleration lane earlier in nine out of ten study sites. Two foot (0.6 meter) lines with 25 foot (7.6 meter) gaps were placed in the neutral area of five tapered and five parallel deceleration lanes on interstate freeways in New Jersey. The application followed a before study while leaving a sufficient time prior to an after study at each location. Two control sites were also studied and did not receive dotted lines. Four additional exits were treated with dotted lines to help relieve a possible novelty effect. The installation of dotted lines appeared to have a more pronounced effect on the paths of exiting traffic using the longer deceleration lanes. (Portions of this document are not fully legible)
