Bow tie

The bow tie intersection is NOT RECOMMENDED

The bow tie intersection is no longer the best way to take control of turns and traffic at divided-road intersections. It is an unrealistic representation of an intersection. Drivers report map errors based on the appearance. It was necessary before the introduction of the junction box and the 3-segment U-turn prevention mechanism, but now there are better methods to control turns and properly account for queuing.

  • Where waze seems to be doing a poor job of keeping track of traffic queuing, a junction box is recommended.
  • To prevent U-turns, rely on the u-turn prevention mechanism below
  • In complicated situations, control u-turns using a junction box
  • Do not add new bow ties to the map
  • When you find a bow tie intersection on the map, check if it can be replaced by a realisticly drawn intersection using other techniques to control turns and traffic.
  • If you think it is necessary to add a bow tie to the map, contact state managers to discuss the intersection.They will most likely recommend a better approach.
