Jughandles are commonly associated with New Jersey State and over the years have been referred to as a "NJ Left" or "NJJI". A Jughandle is a procedure at a signed (signaled) intersection, which disallows a Left or a U-Turn and instead uses a right hand "at grade ramp connector" to allow access off the main roadway prior to or after the intersection and a subsequent indirect turn from the connector or cross street. There are 3 kind of Jughandles in this State per the NJ-DOT. They are:
Type A: Forward Ramps - The ramps exit on the right hand side and accommodate traffic turning both right and left.
Type B: U-Turn Ramps - The ramps allow a safe U-Turn as the driver will exit from the right. Used in absence of an intersection or at a T-Intersection. Commonly used for left turns as well.
Type C: Reverse Ramps - The ramps begin downstream of the intersection to the right and create a loop to meet the cross St/traffic signal.
NOTE: Exit ramps which use local streets to enable this maneuver are NOT considered jughandles.
IMPORTANT: The terms RAMPS and AT GRADE CONNECTORS as used above are simply referencing the NJ-DOT and should not be confused with the same terminology in Waze.
GUIDANCE:
Proposed: Any Jughandle which is unsigned with "Green Signs" aka. BGS/LGS or signed with BGS/LGS which only have the name of the connecting road, should be treated as a standard At Grade Connector. Type: Lowest connecting segment. Name: NO name.
Any Jughandle which is signed using BGS which has a more than one name (street, community, POI) or not the direct connecting segment name fall under the exceptions for At Grade Connectors. Type: Ramp. Name: Match signage. In this scenario the "ramp type" will hide the name in the client, so adding any other relevant signage - white, blue, brown (- ie. All turns, U-turn, XXX State Park) is acceptable only after the wording from ALL the BGS is added.)
Always refer to FC #Continuity when configuring Jughandles.
Parking Lot Roads
This state uses the following national standard guidelines found in the Wiki for Parking Lot Roads.
Alleys
This state uses the following unique guidelines for mapping alleys.
- 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" type.
- 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.
Note: Be careful adding alleys which will be closer to the destination pins for house numbers, as this can cause navigation to addresses on that block to route onto the alley instead of the main road. It may be better not to map these alleys, or you may have to adjust all the address pins to be closer to the actual roads.
Dirt Roads
This state uses the following national standard guidelines found in the Wiki for Dirt Roads.
Note: In other Regions/Countries, the usage of Dirt Roads-4x4 Trails may vary greatly.
