how to divide a road
These instructions have been designed to preserve traffic and address information, and transfer it from the original 2-way road to the divided 1-way roads. It is important NOT to create new segments for the divided road in order to use the information that is already there. Please follow these steps in order for each segment to divided. If there are house numbers on the segment to be divided, you will need to do things that can only be done by level 3 and higher editors.
- Choose a segment to divide
- Cut it in half to create a new junction and save. (illustration)
- Move house numbers
- Next, move the house numbers to the correct segment. Use the [House Numbers] button (or (⇧ Shift+H) to start the house number interface. Click on a house number. Find
- Add a geo node to each segment
- Connect the segment to the intersection

How to properly divide roads in WME
Changing an existing road from single two-way segments to double one-way segments is a process which has the potential to accidentally erase valuable data if done hastily. Road segments which have been driven by Wazers contain complex historical records of the speeds they have been traveled at various times of day. For this reason, it is very important to use the existing segments of a road when dividing it, rather than creating new ones which have no history for Waze to use when routing. There are also often house numbers which need to be preserved and properly positioned when the process is complete. Keeping this data intact requires careful planning and attention to many steps carried out in the optimal order.
Step One: Determine the extent of the division, and decide how much of it should be done at a time. Because dividing is a complicated process, and it’s disastrous to leave roads disconnected, it’s best not to try dividing too long a stretch of road all at once, in case your editing session is interrupted for some reason. If there are only four or five intersections along where the road needs to be divided, it may be good to tackle the whole length at once, but ten or more is probably too much.
Step Two: Make sure that you have the required editing level for EVERY segment connected to any part of the stretch of road you plan to divide. Even one connected segment above your editing rank may prevent you from making necessary connections or setting turn restrictions properly. If you will need something unlocked, get that help before you begin.
Step Three: Scout for House Numbers. Select a segment of the existing road, and press H to bring up the House Number interface. It is often much easier to spot house numbers when the Satellite Imagery layer is turned off. You can toggle the imagery on and off even while viewing house numbers by pressing Shift-I. If there are house numbers, take note of how they are distributed. This may help you make decisions in the next step, where you will be cutting existing segments into the pieces which will be used for the new one-way halves of the road.
Step Four: Cut the segments of road which will be divided, but do not separate them yet. Cutting a segment means adding a junction somewhere between its two ends.
This can be done to a selected segment in one click with the help of a browser add-on such as WME Toolbox, but in some cases the manual method is preferred, because it allows you to place the junction just where you want it. If the house numbers on a segment are not evenly distributed between the two sides of the road, you may want to locate the junction in a spot which requires less work in the next step. To manually add a junction to a segment, you temporarily create a new road segment and connect one of its ends at the spot where you want to create a junction in the other segment, then delete the temporary one, or move it to the next place you need to make a junction.
Next, decide which halves of your freshly cut segments are going to represent which sides of the divided road, but if there are house numbers, don’t separate them yet. Because some of the historical speed data stored in segments relates directly to which directions Wazers have turned when leaving the segments, it is a good idea to leave as many segments as possible connected to their original junctions. If you use an alternating pattern, at least two segments can stay connected at each intersection.
Step Six: Reposition the Stop Points of the House Numbers. Open the house number interface, select house numbers one at a time, and move their Stop Points to the appropriate halves of the segments you cut in the last step.
The Stop Point for a house number is revealed on its associated segment only when you have selected that particular house number. It’s represented by a white dot on the segment, and connected to the house number by a dotted line. This white dot is what you need to move to the appropriate section of the segment, not the house number itself, which can stay put on top of its building. When the road division is complete, these stop points will need to be relocated in their appropriate positions.
