User:Sub5/HNs on Service Roads

Service roads or frontage roads

Service Roads and Frontage Roads are often used interchangeably by Waze Users. Dictionaries even state that the quick definition of one is the other. A more formal definition is along the lines of a road that is parallel or near to a more significant road and that allows people to access local businesses and/or houses. Please refer to the USA National Functional Classification guidance and check your local State's and Region's wazeopedia page for local policies/guidance.

Problems

Service and Frontage Roads often cause routing problems. Some of the more frequent routing problems are:

1. Routing off the main road to the service road, and then back onto the main road.
2. Being navigated to the main road for an address which is on the service rd. The address may not be reachable from the main rd, especially if there is a barrier between the roads. Additionally stopping may be dangerous or prohibited on the main rd.
3. The address is not found in search since it is listed on the service road, but it should use the main street's address. This causes the search to use 3rd party results even if there is a confirmed HN in Waze, leading to routing issues.
4. Drivers unknowingly taking the main road instead of the recommended service rd, and then being unable to make a recommended turn further down since they are on the main rd instead of the service rd. This results in Turn Not Allowed, Incorrect Junction, or Wrong Driving Directions URs.

Here is an example at Arlington Blvd in Northern Virginia. Reporter was unable to make the turn from Arlington Blvd to N Montague St because they did not follow the recommended route. The recommended route was the PL above. [Note: Editors need to make sure that the service road is labeled service road. Sometimes they are found labeled the same as the main road and Users don't understand to go to the service road. Users who turned on the main road and won't be able to make the subsequent turn.]

Solutions

Naming service/frontage roads

1. To prevent routing errors from Big Detour Prevention make sure that you have at least one segment that does not have the "Main Road" name as either primary or alternate name. This can be done by having an unnamed segment or the name of an intersection road.
2. Check for any Bowties, or forks where the main road connects directly to service road, or a feeder road connects directly to both the main and service roads, and eliminate any Best Continuation issues.
3. Check and adjust if necessary any slip roads (entrance or exit), in most cases these are best left as no-name segments.
4. Test the routing after the tiles are built.

House numbers on service/frontage roads

Nudging all the HNs a bit to move the anchor point to the service road vice the main road has 2 benefits:

1. It confirms them given them routing priority over 3rd party sources
2. It snaps the HN stop point to the service road.
3. Check for any Bowties, or forks where the main road connects directly to service road, or a feeder road connects directly to both the main and service roads, and eliminate any Best Continuation issues.
4. Check and adjust if necessary any slip roads, in most cases these are best left as no-name segments.
5. Test the routing after the tiles are built.

Procedure to move house numbers from main road to service road

• Starting with HNs on the [Main St]

  

• Temporarily name the service road with the [Main St] as the primary road name. (No Service Rd in the primary name)

  

• Save the road name change
• Edit HNs by moving each applicable HN from the real Main St to the Service Road
