Bus or taxi only lanes 
When a road or lane is designated for bus or taxi use only, mark that road segment(s) with an allowed time based segment restriction for bus and/or taxi. The entire segment, right lane, center lane, or middle lane can be selected as appropriate on the second pop up window of the time based segment restriction. This will prevent the Waze router from using that segment(s) for general traffic, since the majority of the users will not be able to use that lane. It will only route if the taxi or bus type of vehicle is set in the user's settings. (Taxi is currently available but bus is a potential future selection). Set the turn restrictions as appropriate for the legal usage by taxi and/or bus vehicles.
Change the road segment(s) to the proper Road Type based on the functional classification and the Waze correlation table. A Private Road segment is no longer required.
If a road is one-way, but allows bus or taxi traffic to flow the other direction, leave the road as one-way with the normal flow of traffic, add the time based segment restriction for the Bus and/or Taxi in the appropriate direction. There is no need to create a second road traveling the opposite direction for the bus and taxi-only traffic.
