Emergency Vehicle and DOT Service Roads: typo
#* Since freeways are given the highest priority of all, having other high-type roads is necessary to provide viable alternatives to the routing server in case freeways are clogged with traffic.
# When viewing the map, more important roads should appear at the far zoom levels. Without proper types, the zoomed out display can be misleading.
 The {{Freeway}} and {{Ramp}} # Certain [[#Other drivable roads|other drivable road types each have their own special rules]] generate [[Routing penalties#Segment properties|transition penalties]] when a route leaves them onto a different road type. The {{Major Highway}}, {{Minor Highway}}, and {{Primary Street}} types are designated using a set of minimum criteria, as explained #* This can be useful for areas like [[#HighwaysPrivate Installations|belowprivate installations]]but can also cause dramatic and unexpected routing results.

Road types do not affect naming. See [[Road names]].
== {{@|Public roads}} ==
Public roads are those that can be driven by anyone. Naturally, they are by far the most important roads on the Waze map.
 
The {{Freeway}} and {{Ramp}} road types each have their own special rules. The {{Major Highway}}, {{Minor Highway}}, and {{Primary Street}} types are designated using a set of minimum criteria, as explained [[#Highways|below]].

=== Unpaved checkbox [[File:Checkbox.png|50px]]===
 
The [[FIle:Unpaved attribute.png|90px]] checkbox is an attribute that can be applied to any road type. It indicates that a road is not paved with asphalt or concrete. The unpaved attribute affects routing over drivable road types; it does not really affect non-drivable road types, since the client does not use them for routing. Based on user preference, destination, and other settings options, the Waze client may avoid routing them over otherwise drivable segments when the 'unpaved' attribute is checked.
[[File:RoadPicN6.jpg|right|300px|RoadPicN6.jpg]]
==== When to select the Unpaved attribute ====
 
'''Any drivable road which is not paved with asphalt or concrete''' should have the Unpaved attribute box checked.
 
<sub>Check your [[Mapping resources|state's page]] for details on whether there are additional guidelines for roads that are in '''''uncommonly poor condition by local standards''''' or contact your [[Regional Coordinator]] for further guidance.</sub>
 
==== User setting options for the Unpaved attribute ====
This attribute has the unique property in that Waze users may select when not to be routed over unpaved road segments. Users may choose:
* 'Dirt roads - Don't allow' - Avoids through-routing on all unpaved roads
* 'Dirt roads - Avoid long ones' - Avoids through-routing on long unpaved roads
* 'Dirt roads - Allow' - Allows through-routing that could include unpaved road(s) (i.e. ignores whether roads have the unpaved attribute checked)
:''The Client still refers to these settings as "Dirt Roads", but it will be updated soon to read "Unpaved Roads". Rest assured they apply to this [[FIle:Unpaved attribute.png|90px]] attribute, and not to the {{Off-road}} type.

===Exceptions===
Occasionally, if deemed necessary for proper routing, a particular road's type may be set higher than as prescribed in these rules. If a road has a higher or lower type than what's specified in these rules, there may be a reason for it. Special rules are used to determine the road types of [[Creating and Editing a roundabout#Road type|roundabouts]] and [[At-grade connectors#How to label the connector type|at-grade connectors]]. ==== Routing road type ====Apart from changing the nominal road type, level {{rank|routing}} editors can also change the [[Creating and editing road segments#Special properties|routing road type]] (also known as routing preference) to one type higher or lower, which only affects [[Routing server#Changes in routes due to different route lengths|long-distance aspects]] of road type behavior while maintaining the same appearance, [[How Waze determines turn / keep / exit maneuvers#Best Continuation|best continuation]] and [[Detour Prevention Mechanisms|detour prevention behavior]] of the nominal road type. These exceptions to the rules should be reviewed with local leadership before implementation. ====Continuity====[[File:35-71.png|thumb|300x300px|SR-435 has the Minor Arterial functional class , so it would normally have the Minor Highway road type in Waze. Since it is signed as the way from one Freeway (US-35) to another (I-71), its routing road type has been promoted to Major Highway, enabling the routing server to use it on routes from WV to IL. It's nominal road type remains Minor Highway to preserve appearance and detour prevention.]][[File:M55-66.png|thumb|300x300px|These Michigan State Trunkline Highways have the Minor Arterial functional class, so they would normally have the Minor Highway road type. However, even without signage indicating their longer-distance use, they have been upgraded to Major Highway in order to be used in routes between southwestern Michigan and the Upper Peninsula.]]One common reason for a road to be set to a higher type is for the purpose of maintaining '''continuity''' between two roads with higher types. Promotion for continuity is usually indicated by signage: A certain less important road is signed as the way to get between two different more important roads. For example, a freeway exit from I-70 is signed as "Exit 142: US-40 / Gratiot", indicating that this is the intended way to get to US-40, with Principal Arterial functional class. Between the ramps and US-40 is CR-30 with Local functional class. The rules on this page would normally dictate that this road be set to Primary Street, but in long-distance routing it may be removed from consideration, or '''[[Routing server#Pruning|pruned]]'''. This can be prevented either by assigning the Major Highway type outright or by assigning the Minor Highway type with a +1 routing road type, which would cause it to be treated like a Major Highway for long-distance routing. Use of routing road type is preferable to avoid unintended side effects on the behavior and display of the road.
Apart from changing the nominal road type, level {{rank|routing}} editors can also change the [[Creating and editing road segments#Special properties|routing road type]] Certain situations may require continuity upgrades even without signage to support them. Examples include but are not limited to one type higher or :* Sparsely populated areas connected by long roads with lowerfunctional class* Places where highway designations end abruptly, which only affects [[Routing server#Changes in such as jurisdictional boundaries* Alternate routes due used as detours for main highways subject to different route lengths|frequent or long-distance aspects]] term closures* Urban or suburban areas in the midst of road type behavior while maintaining the same appearanceredevelopment, [[How Waze determines turn / keep / exit maneuvers#Best Continuation|best continuation]] and [[Detour Prevention Mechanisms|detour prevention behavior]] where functional class may be out of the nominal road type. These exceptions date* Connecting roads that may be too short to the rules should be reviewed with local leadership before implementation.noticed during state functional class assignment
Special rules are used to determine When promoting for continuity, the effective road type of the connecting road types should match the ''lower'' of [[Creating and Editing a roundabout#Road the two roads that it connects, similar to type|roundabouts]] and [[Atselection for at-grade connectors#How , up to Major Highway. Since Major Highway is never pruned, there is no need to promote something to label Freeway with routing road type for continuity reasons alone, and the connector nominal Freeway road typeshould only be used for controlled-access highways that meet the criteria [[#Freeway|at-grade connectorsabove]].
Road Continuity upgrades prevent Waze from pruning out valid routes, and in extreme cases they can mean the difference between getting a good route and getting no route at all.=== Unpaved checkbox [[File:Checkbox.png|50px]]=== The [[FIle:Unpaved attribute.png|90px]] checkbox is an attribute that can be applied to any road type.

==== {{@|Emergency Vehicle and DOT Service Roads}} ====
[[File:Emergency.jpg|right|300px|Emergency.jpg]] Limited-access service roads, such as those marked for "emergency and authorized vehicles only" should not generally be mapped, and if there is a need to map them, they should not support routing nor appear like other roads. The clearest way to do this is to map them using the {{Private Road}} type, add [[partial restrictions]] on them to prohibit routing for all times and vehicle types and include a description within the restriction to explain the reason for mapping. Another, older method also involves using the {{Private Road}} type, disconnecting the limited-access road and locking as high as possible. This is also valid. Examples of such roads include fire roads prohibited to all non-service motor vehicles, patrol roads for park service vehicles, and service cutoffs across the medians of divided highways.
