In Houston, Houston Metro has described two different types of high occupancy lanes. There is a Vehicle (HOV) lane which is subjected to restrictions based on time and type of vehicle with number of occupants being a type of vehicle. They also have Toll (HOT) lanes which are time restricted toll roads. What can make the restrictions particularly challenging is that a single lane will often be both a HOV and HOT lane. [http://www.ridemetro.org/Pages/HOVandHOTLanes.aspx Metro] provides a general description of high occupancy lanes which happens to provide includes links to the individual lanes where the lane's time based restrictions are described.
Unique factors that should be considered are
# The times on the Metro site specify when it is legal to enter the lane not when it closesa wazer must exit the lane.
# HOT lanes are electronic toll roads. HOV lanes are not toll roads.
# The HOT lane's toll is a fixed amount regardless of how far you drive in the lane.
There was a time when the entire high occupancy lane in waze was restricted to all traffic from 11 AM to 1 PM (the trasition transition window between the end of morning inbound traffic and the start of afternoon outbound traffic). This inadvertantly inadvertently resulted in navigation errors as a vehicle entering the lane at 10:59 AM would be directed to leave the lane at the first opportunity rather than following the best route to the wazer's destination. The solution to this class of issues is to place the time restrictions on the entrances to the high occupancy lanes. Once in the lane there should be no timed based restrictions.
Toll is an attribute applied to a road segment; it can not be turned off and on. Therefore, every high occupancy lane that is both a HOV lane and a HOT lane must have two entrance segments. One tolled for the HOT lane and the other non-tolled free for the HOV lane. That way, a HOV-2/HOV-3 vehicle may still be directed to use the HOV while avoiding all other tolls roads.
Waze assumes that the tolls paid are proportional to the distance driven yet HOT lanes have fixed tolls. The solution is to keep the length of the tolled segment short so that variations in length between one entrance and the next are negligible in comparison to the distance between the entrances.
Any time you are setting a road to allow ''HOV - 2'', it must also be set to allow ''HOV - 3''.
''In the USAHouston '' motorcycles are allowed to use HOV lanes, therefore when setting partial restrictions to only allow ''HOV - 2'' (''HOV -3''), ''Motorcycles'' should also be allowed (unchecked). Some jurisdictions also ''Taxis'' and ''Buses'' to use the HOV lanes. These should be set accordingly in those jurisdictions.
