Turns

Time Based Turn Restrictions (TBTRs) are used when certain turns are partially restricted from one segment to another. If the turn is always restricted for all vehicles then use a red turn restriction; TBTRs are not to be set to 24/7 for all vehicles. TBTRs are used to only restrict certain hours, days, dates, and/or certain vehicle types.

Turn restrictions

Turns are set up for traffic flow or restricting traffic are set with turn arrows—the arrows that appear at the end of a selected segment. A restricted turn is indicated by a red arrow with a red do not sign next to it (upper left arrow in picture below). A partially restricted turn (TBTR) is indicated by the yellow arrow (lower right arrow in picture below). A turn that is open (not restricted) to all traffic is indicated by a green arrow. For two way segments, there are u-turn arrows that follow the same color indications. Hover over either a green or yellow arrow and a grey box pops up with that particular turn's turn instruction override selection, the turn restriction selection, and the difficult turn attribute selection (upper right arrow in the picture below). Above the grey box is a label for turn to name of segment (if named) or "no street" (if unnamed).

Scheduled turn restrictions

When not all times, days, dates, or vehicles are restricted from turning, you can set a scheduled turn restriction from one segment to another. Turns that are restricted to traffic during certain periods are "time based turn restrictions". Restrictions can either prohibit or allow vehicles by time, day, date, or type.

To enter a TBTR:

1. Select one segment
2. Hover over a GREEN or Yellow turn restriction arrow
3. Grey box appears

   

   • a) "VOICE PROMPT" for the Turn override instruction is listed on top
   • b) "RESTRICTIONS" for the TBTR is listed in the middle
   • c) "DIFFICULT TURN" for the Difficult turn (DT) attribute is listed on the bottom
4. Click the "Waze Selected" area to select a turn instruction override and a drop down menu appears
5. Click the "Add restrictions (or Edit restrictions)" icon to add a TBTR and a popup window appears.
   • a) If "Add restrictions" is selected then a popup window goes directly to TBTR attributes

     

   • b) If "Edit restrictions" is selected then a popup window with a summary of existing TBTR(s) is displayed; click the Add new radio button to get to the attribute popup window where you can add another TBTR

     

6. Click "Yes" to select the DT attribute or "No" to deselect the DT attribute; the Difficult Turn is described below
7. Click Save icon on the grey Waze bar to save any changes

If the turn restriction is part of a junction box and there is one or more alternate route within the junction box, then a SWITCH ROUTE line will appear between the restrictions and difficult turn lines. Please see Switch route selection for description of this feature.

TBTR pop-up window attributes

The second line will display Turning from [original segment] to [destination segment] is restricted on. There are several attributes that can be selected for the restriction:

1. Days
2. Hours
3. Applies
4. Restriction Type
5. Additional information text box

Days (of week)

Select the applicable days of the week that the restriction will be active. Use the Select all or Select none link to more quickly change all the check boxes. The default is all days of the week. Your display order for the days will depend upon your country settings in your browser and may not exactly match the image above. Mon-Fri and Every day are the most common restriction groupings in USA.

Hours (of day)

Select the applicable hours of the day that the restriction will be active. For restrictions that apply all day long, use the default setting of All day. If the restriction is for only certain periods of time during the day, then deselect the All day radio button to allow the time to be changed. You can click the hours or minutes fields to enter times directly, or click the clock icon next to the time to enable input panels. The schedule uses a 24-hour notation. The restriction will start at the beginning of the minute designated in the start block. The restriction will go till the 59th second of the minute designated; so if you state an end time of 08:00 it goes till 08:00:59. So if a posted restriction ends at 08:00 it is advisable to end the waze restriction at 07:59; this will have the 08:00 time enacted vice carrying the restriction over for an additional minute. If the end time is selected after 23:59 then the restriction will carry over till the next day.

24-hour time	12-hour time
00:00 (midnight)	12:00 AM
01:00	1:00 AM
02:00	2:00 AM
...	... AM
10:00	10:00 AM
11:00	11:00 AM
12:00 (midday)	12:00 PM
13:00	1:00 PM
14:00	2:00 PM
...	... PM
22:00	10:00 PM
23:00	11:00 PM

In a 24-hour format, time is represented with unique hours of the day that do not require the AM and PM indicators. To convert from 24-hour time to 12-hour time (or vice versa), use the table on the right.

The minutes remain the same between the two formats.

Alternately, you can use the following math to convert from AM/PM to 24-hour format:

• For AM times, use the time directly: 8:45 AM = 8:45 (in 24-hour format)
• For PM times, add 12 hours to the time: 8:45 PM = 20:45 (in 24-hour format)

For example, a schedule of 10:00 AM to 3:00 PM is entered as 10:00 to 15:00; a schedule of midnight to noon (12:00 AM to 12:00 PM) is entered as 0:00 to 12:00. A schedule of 3:00 PM to 5:00 AM is entered as 15:00 to 05:00.

The time that should be entered is the local time of the road as on the local signs. The Waze server knows the local time zone and will schedule the restriction correctly.

Daylight savings time is automatically accounted for as long as the Waze client app is properly set to the correct local time.

Entering midnight

If a scheduled restriction is between 8:00 PM and Midnight, then enter "20:00 - 23:59". Technically if you enter "20:00 - 00:00" it will go to 00:00:59 but is more or less an equivalent result.

Crossing midnight

If a restriction occurs only during nighttime hours and opens in the morning, e.g., restricted between 10 PM and 5 AM, then enter the From time as 22:00 and the To time as 05:00. You will notice an information box that says the restriction will end of the following day. If this restriction is only on a certain day of the week, e.g., Saturday night and Sunday night, then select the day of the week for Sat and Sun matching the start of the restriction. There is no need to include Monday because it is automatically covered. Including the Monday check box would add a third day starting at 10 PM Monday.

Applies (to dates)

The default setting is Every week meaning there is no limit to the date range so as soon as you add the restriction it will be active every week until it is removed. Optionally you can select the radio button for Range of dates to limit the restriction to a certain number of days. Press the button displaying the date to display two calendars. The one one the left shows the start date and the calendar on the right shows the end date of the restriction. Note these date are inclusive meaning the restriction will include both dates (and all the ones in between) when determining the restriction. When you have selected the date range press the green Apply button. The date range is displayed in DD/MM/YYYY format. To remove the date range, simply select the Every week radio button again.

Remember that the end date will consider the entire day based on any time settings also configured. If the time crosses midnight, the next day will automatically be included for that time period and so that the restriction ends at the appropriate time.

Restriction types (Allowed/Prohibited)

This is where the two main Types of restrictions are selected that appear on the first pop-up window.

1. The two restriction Types displayed are:
   • allowable
   • prohibited
2. Restriction Types are added as Lines under the applicable direction of turning.

   

3. Restriction Lines contain Rules which are constructed here on the second pop-up window
4. Allowable restrictions have green backgrounds
5. Prohibited restrictions have red backgrounds
6. Restriction Rules combine the vehicle type allowed and/or prohibited
7. Allowable and Prohibited rules have different ways of selecting vehicle types; most editors will use one or the other restriction type but not both.
8. Remember
   • a) Each restriction Type on the first pop-up window is compared to other Types as an AND statement.
   • b) Each restriction Rule on the second pop-up window (within the Allowable restriction Type) is compared to other vehicle type(s) in that restriction line as an OR statement.
9. Note that the restriction's background color should change to red for prohibited and green for allowed
10. Select the applicable Allowed Vehicle type by clicking on the +

    

11. Private car is added to the restriction Line

    

12. The vehicle type can be changed by clicking on Private car bubble

    

13. Only one vehicle type can be selected per Restriction Rule
14. If no vehicle type is selected then Waze defaults to have the restriction applicable to all vehicles
15. If there is more than one vehicle type that needs a restriction then click Add a new rule and then the + and Vehicle type till all applicable vehicles are added as a separate Rule in the one Restriction Line

    

16. Click Add button in bottom right corner of the second pop-up window
17. For Prohibited restrictions you get to enter one Rule and mark all the prohibited vehicle types at the same time in the same rule.

    

18. Prohibited restrictions default to All vehicles
19. Select Only to be able to pick what vehicle type(s) will be prohibited
20. Note DO NOT select conflicting restrictions. There is no prioritization of the restrictions which is why it is advisable to only use Allowed OR Prohibited TBTRs but not both together on the same turn.
21. Click Add button in bottom right corner of the pop-up window
22. Click Apply button in bottom right corner of the TBTR summary pop-up window
23. Click Save icon on the grey Waze bar

Difficult turn

This setting tells the routing server to add a routing penalty to the turn, meaning when calculating the time to reach the destination, this turn will include extra time so that other routes are more likely to be selected if this turn is only marginally better than another nearby route. The user enables this option by selecting "Reduce difficult intersections" within the "Navigation" section of the "Settings".

A turn can be considered difficult for many reasons including but not limited to the following:

Heavy traffic

• Turn left across traffic that may be continuously flowing or fully stopped and into traffic that may also be continuously flowing or stopped.
• Turn right into traffic that may be continuously flowing or fully stopped.

Poor visibility

• Turn (left or right) into quickly moving traffic with poor visibility from:

• a crest in the road
• a sharp corner
• an obstacle

A turn can be identified as difficult by 'multiple' drivers submitting URs or by the direct knowledge of the editor.

Do not put a DT in for the following situations:

1. If the poor visibility turn is the only valid way into the segment (The DT will not affect routing and should be omitted)
2. A left/right turn at a traffic light
3. A left/right turn where there are stop signs at all paths of travel
4. A left turn where there is a dedicated left turn lane even if left turn lane is not an at-grade connector (AGC) (car is protected and if time to turn is long algorithm will pick up)

As of May 2016, the difficult turn box is a 24 hour every day setting and not related to any other time-based restriction. That may be something available in the future but not at this time.
