User:Hawkeygoal/Global Pages/RTC Cross Traffic(2016 06)

Overview

The goal of this page update is to provide guidance for editors relevant to lessons learned in handling real-time closures (RTC) and cross-traffic at junctions.

This information is a draft under development. It should not be considered official guidance.

A specific challenge addressed by this revision is the routing to a destination on a closed segment from the far side of a adjacent thru-closure. For example, rather than routing to the destination from Whitworth the route suggest approaches from other side of a closure necessitating either manually navigating to the far side or crossing a closed intersection.

Junctions and cross traffic

When adding a Real-Time Closure consider whether any cross traffic will be blocked as well.

Often in work zones and for special events (parades, 5K and 10K road races, marathons, half-marathons, festivals) cross traffic is not allowed at one or more junctions.

It has been observed that Waze will not route through a closed segment; however, it will route on to or off of a closed segment to reach a destination or leave a starting point on that segment. If traffic going across your Real-Time Closure must be blocked at a junction, you will need to close at least one of the cross street segments as well.

• One-way cross street

• Close the cross street s-in segment.

This prevents traffic from routing through the junction and onto closed s-out segments to reach a destination.

• Two-way cross street

• Close both cross street s-in segments in both directions.

Closing a single segment will allow routing across the junction to destinations on s-out segments. Closing both segments will prevent routing across the junction when to reach a destination or leave a starting point.

• T-intersections

• Close the cross street s-in segment in the direction approaching the junction.

This is necessary only to stop routing to destinations on s-out segments of the main closure.
