- Alleys should always be mapped if they have a name.
- Alleys should always be mapped if they are the sole access to a home or business.
- Alleys should always be set to "Parking Lot Road"
- Some alleys mapped before these guidelines are mapped as "Private Road". It is okay to change these to "Parking Lot Road".
- Alleys are normally mapped if they are acknowledged by the municipality.
If an alley does not meet the above criteria, mapping is optional. Leave the name field blank. Always disable the straight turn restriction from one alley to another when it crosses another road to prevent alleys from being overly used in routing.
See the Driveways article for more details.

When mapping roundabouts in Washington state, it is important to know the difference between roundabouts and traffic circles. Traffic circles are small circles to help slow traffic at intersections.

Here are some examples of roundaboutsː 
In Washington, we usually only map roundabouts. We don't map traffic circles unless:
- Specific directions are needed to navigate the traffic circle (i.e. more instructions than just turn right or turn left)
- If the traffic circle is on a Primary Street with high traffic or higher road type(contact a SM for traffic circles on primary streets)
- The traffic circle is larger than 12m.
Dead end segments
Dead ends should all have nodes on the dead end side of the segment. It was possible in older versions of WME to add a road with a dead end and no node. As of July 2014, U-turns at dead ends or cul-de-sacs, no longer need to be adjusted in a particular way. WME no longer provides a link to adjust it. Please make sure U-Turns on the end of cul-de-sac with private driveways are Not Allowed. Example
See Non-driveable roads for guidance that may not be universal to all other states and territories.
