In cases where a ramp terminal involves a surface street junction, the. procedures for signalized or unsignalized intersections must be used to assess the complete. performance of the ramp. The ramp junction methodology estimates the performance of the. ramp-freeway junction.
61. Median Crossover/Left Turn Lane Type. Definition: The presence and type of crossover/left turn bay in the median along the segment. Note: This element is intended to capture the typical median characteristic along the segment at non-intersection locations. Information on intersection-related turn lanes will be coded in the Junction File. Attributes: None; Median crossover, no left turn bay Median crossover, left turn bay Median crossover, directional left turn lane bays (to prevent crossing traffic from driveways)
