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 merge 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 merge process does not support three different speeds on a single segment. Thus, please do not add more than one single-lane restriction on any segment.
Speed measurements are gathered per lane, not per vehicle 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 restriction is used, speed data will be collected properly.
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 restriction is used, speed data will be collected properly.
The routing server uses this speed data for calculating the best routes for the user. From these routes, speed data is used to calculate the trip duration. This calculation uses either vehicle speed or motorcycle speed since motorcycle speeds are kept separately.
