Propose to add a new section to the HOV wazeopedia
Segment speed tracking
As part of the HOV/Express Lane process, Waze computes a maximum of two separate road speeds per segment during the route evaluation process. While the Waze editor interface allows the addition of multiple single-lane restrictions (e.g., HOV left lane, regular traffic center lane, and Bus right lane), the data collection process does not support three different speeds on a single segment. Therefore do not add more than one single-lane restriction on any segment.
Speed measurements are normally gathered per lane, not per restriction type—for example, an HOT or Express road segment allowing both toll free and tolled traffic in the same lane gathers only one set of average speed data. This makes sense, as vehicles in the lane are traveling together as a single pack. In other words, the complexity of restrictions in a single lane does not matter—as long as only one single-lane is used for allowable/toll free/prohibited restrictions, speed data will be collected properly.
Note motorcycle speed data is collected separately from the other vehicle data and is discussed on the [Road segment speed data] section.

This is for the Road segment wazeopedia page:
Speed data in normally collected by the segment with a maximum of two speeds for any road segment to account for lane (right/center/left) restrictions. A motorcycle's ability to conduct lane splitting can alter their expected estimated time of arrival; therefore, motorcycle speeds are the only known exception for a vehicle type having different speed history. Motorcycle speeds are kept alongside the normal two sets of speed data for private/taxis/electric vehicles. The routing server uses the appropriate stored speed data and current conditions for calculating the best routes and estimated time of arrival based on the user's selected vehicle type.
