Bow tie
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 realistically 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.
