Junctions & signals

Traffic Architect Junction & Signal Guides

Choose Traffic Architect help for allowed turns, traffic-light timings and phases, or interchange placement. Check the tool and version before editing.

Which part of the junction needs changing?

To prevent a movement, use junction turn bans. To choose a specific outgoing lane, use the lane-connector guide. To change green time or investigate a phase reset, use the versioned signal guide. For a prebuilt road arrangement, check interchange placement and generated turn rules.

These change different layers of the same junction. If a movement edit leaves a destination inaccessible, follow the No Route Available checks instead of assuming the physical road disappeared.
