High Occupancy Vehicle (HOV)

Intro

Waze has HOV routing! This feature puts Waze out in front of the other navigation systems, but we need to know how to properly configure the map for a great user routing experience. There are a lot of considerations for getting all the options included, so please take your time and read it through the entire article prior to editing. If you have questions, then please reach out to your State Manager or Regional Coordinator and we’ll get you some help.

Definitions

HOV

HOV – High Occupancy Vehicle. Has more than one person in the vehicle. It is often posted with a number after the acronym; HOV-2 or HOV2+. The number specifies the number of people to meet the HOV requirements; ex. HOV-3 means that three or more people need to be in the vehicle.

HOT

HOT – High Occupancy Toll. This is a combination of toll road and HOV. Sometimes called “Lexus Lanes” since people can buy their way onto roads with less congestion. Electronic toll roads often require a special transponder set to HOV which broadcasts the car meets the requirements so that the toll is not charged.

Express Lanes

Express Lanes – There are two main types of Express Lanes on the interstate system. They can either be HOT lanes or lanes that have limited exits. This wiki section will just deal with the HOT type of Express Lanes and the segments should follow the guidance for HOT below.

Clean Air Vehicle

Clean Air Vehicles – future feature These vehicles meet the requirements for low emissions for the state that the person is operating the vehicle. The vehicles are normally either a hybrid or electric or natural gas vehicle. Note some states require special permits or license plates to qualify.

Nearby HOV Attribute

The Nearby HOV attribute is a check box that is used for designating roads that close to the HOV lane so that Waze’s algorithm can differentiate between the varying speeds

Location The Nearby HOV attribute is under the road type selection when a segment is selected

DO NOT SELECT this attribute on the actual HOV road segments. Even for road segments that have regular and HOV lanes on the same segment. (i.e. the segment has an HOV lane that is separated by dashed line.)

Ensure the Nearby HOV attribute is selected on all parallel road segments going the same direction as the HOV traffic that are within (XXX feet) of an HOV segment.

Note for reversible HOV lanes there may be road segments on both sides of the HOV lane that require the Nearby HOV attribute to be checked.

How to map HOV lane segments

Separated HOV lane

Separated HOV lanes are either lanes that are:
1. Completely separated by a physical distance from the normal lanes (ex. land, curbs, shoulders)
2. Separated by a concrete barrier from the normal lanes
3. Separated by solid or double solid lines from the normal lanes
4. Separated by flexible barriers from the normal lanes

Insert pictures of the separations

Mapping separated lane - The separate lane should be mapped as a normal parallel segment that is distinct from the normal road.

Dashed line separation

Dashed line separations are transition areas where vehicles can merge from HOV lanes to regular lanes or from the regular lanes to the HOV lanes.
There are two types of situations with the HOV dashed line separation:
1. Continual dashed line for the entire HOV lane. HOV vehicles can enter or exit at any location on the HOV lane
2. Transition zones, where there is a limited are for entering or leaving the HOV lane

Mapping continual dashed line HOV lanes
1. Current guidance in forum is to map the HOV lane on the regular road segment
2. Follow restriction guidance for combined segment HOV and regular traffic in different lanes below

Mapping transition zone dashed line HOV lanes
- Current forum guidance: This requires a merge ramp from HOV to the regular lanes and a merge ramp back to the HOV lanes. Be sure to have each ramp labeled so that people know when to get into the regular lanes and the HOV lanes. This configuration does cause problems with excess commands for people already on the HOV lane and staying on the HOV lane. Insert picture of an example
- Possible guidance;
  1. Have separate parallel segments for the HOV and regular lanes the entire length of the HOV lanes
  2. Add ramps to make a V entrance/exit to HOV lanes
  - a) Add a ramp with to HOV coming from the regular lanes to the start of the transition area (Prompts user to enter the HOV lane)
  - b) Add a ramp with to return to regular [Road name/Route number] (Prompts user to exit HOV lane either for upcoming exit or if traffic is faster in regular lanes)
  1. Add another V entrance/exit ramps at the end of the transition zone if the zone is over 0.5 miles/xxxx meters long
  2. For very long transition zone, V entrance/exit ramps can be added every 0.5 miles/xxxx meters

Entering HOV restrictions

Separate segment HOV only

To mark a segment for HOV use including the required number of passengers:

Select Add restrictions (Time Based Segment Restrictions) on the left panel when the segment is selected
Select Entire segment in the Applies to section
Select HOV in the Applies to section
Select appropriate Days, Hours, and Every week [Note every week can be a date range but probably not used for HOV]
Driving is _____ for
1. Select toll free if free for HOV vehicles
2. Select allowed for if there is a charge even for HOV vehicles
3. Select prohibited if there are times when the road is closed to all traffic, ex. reversible lane
Select Num passengers by clicking the + on the green add restriction banner and a drop down menu will appear
1. At least 2 passengers is added
2. Select number of passengers required by clicking the At least 2 passengers and a drop down menu will appear with selections for At least 3 (4) passengers
HOV lane only part of the day/Open to all rest/part of day/Reversible lane
1. Make sure one period is added for the segment then add additional restrictions till all appropriate times are added for one direction
2. Add the appropriate time and restrictions for the opposite direction on reversible segments

Note be sure to add the Driving is Prohibited period(s) if a reversible lane does not allow traffic to prevent misrouting.

Separate segment HOT/Express Lanes (HOV or toll allowed)

Normally the HOV vehicle is allowed to use the lane for free while other vehicles have to pay a toll. The toll rate can be variable with surge pricing to control the number of vehicles that are not HOV on the road. Therefore this is setting up or statements. A vehicle can use the road for free if meeting the HOV requirements or the vehicle has to pay a toll.

For each segment that is HOT/Express Lane

Set up the HOV restrictions following the instructions for HOV above [Note do we want to link to above or repeat steps a drop down?]
Set up the applicable segment for toll road by selecting the applicable toll transponder(s)
Select Add restrictions (Time Based Segment Restrictions) on the left panel when the segment is selected
Select allowed on the Driving is ____ for section
Select subscription by clicking the +' on the green add restriction banner and a drop down menu will appear
Select applicable transponder company by clicking the Sunpass and a drop down menu will appear with all available companies

Combined segment HOV and regular traffic in different lanes
