What causes fatal error 6500 (e.g., “Link (32, 369) defined on RT 19 does not belong to any disjoint freeway segment.”)?
Fatal error 6500 is usually related to incorrectly specifying the link type (i.e., ramp versus mainline) or specifying invalid freeway segments. Valid segments begin at an entry or entry interface node and end at an exit or exit interface node. There must be a continuous sequence of mainline links between the beginning and the end of the segment.
