126. Intersection/Junction Geometry

Definition: The type of geometric configuration that best describes the intersection/junction.

Attributes:

  • T-Intersection
  • Y-Intersection
  • Cross-Intersection (four legs)
  • Five or more legs and not circular
  • Roundabout
  • Other circular intersection (e.g., rotaries, neighborhood traffic circles)
  • Non-conventional intersection (e.g. superstreet, median U-turn, displaced left turn)
  • Midblock pedestrian crossing

See Figure 6 for additional detail.

Priority: Critical

HPMS/Tool Requirements: HSM/IHSDM (Required), SafetyAnalyst (Required)

There are eight illustrations of different types of intersections in the figure labeled as: T-Intersection; Y-Intersection; Cross-Intersection (four legs); Five or more legs and not circular; Roundabout; Other circular intersections (e.g., rotaries, neighborhood traffic circles); Non-conventional intersection (e.g., superstreet, median U-turn, displaced left turn); Midblock pedestrian crossing.
