Overview
In the Waze editor and routing system, there are three basic types of restrictions:
- Vehicle type
- Segment or traffic flow direction
- Turn restrictions
Each of these three types of restrictions can be set permanently or time-based. Here are some examples:
- Interstate truck-only ramp
- No trucks allowed between 9a-3p weekends
- No left turn 7a-9a and 4p-6p weekdays
- HOV lanes
- Freeway express lanes which are a single roadway, but run a different direction for morning and evening commutes
- Vehicle towing a trailer
Waze is very flexible in the types and combinations of restrictions allowed to be specified in the map editor. This flexibility is excellent and required of a mature navigation system. If there is a downside to this flexibility, it is complexity. Specifying, maintaining, and not accidentally destroying restrictions on segments or turns takes great care, patience, and requires checking and double-checking before making any drastic changes.
