Median Type – This code is a classification of the type of median on the segment of
road separating the travel ways for traffic in the opposite direction. Starting and ending
reference points are to be measured at the location where the physical change in median takes
place. Painted medians are identified by yellow striping. Continuous left-turn lanes are generally
not to be considered medians, with the exception of two-way left-turn lanes (TWLTL), which are
identified by a solid yellow stripe and skip stripe on both sides of the median. Transitions
between striped no-vehicle travel medians and TWLTL warrant segment breaks, but transitions
between TWLTL and designated left-turn lane striping do not warrant segment breaks, provided
that the overall median width remains constant. When left-turn lanes are present, a median may
still exist between the inside left-turn lane and the opposing lane of traffic. In the event that the
inside left-turn lane is immediately adjacent to the opposing lane of travel (separated only by a
double-yellow stripe), the median type should be entered as no-vehicle travel with a width of 0-
feet in order to preserve the cross-section width (where applicable).
