*it allows Waze to provide door-to-door directions within the lot;
*it allows Waze to recognize that the Waze client to get is off the main road, avoiding erroneous traffic reports.*it using the special type prevents the Waze client from routing thru-traffic along through the parking lot segments.
'''NOTE:''' Most For marking parking lots should '''with places see the information on the [[Places/Parking lot|Parking Lot Place type]]. Parking lots roads are not''' be designated as a Waze "limited to use with the parking lot placetype," and especially not an Area Place (previously known as Landmarks)though they are sometimes used together. The Parking Lot Road type exists to allow the mapping of parking lots, while discouraging the routing server from using them for through navigation. Waze applies a [[Routing penalties|transition penalty]] for leaving a Parking Lot Road segment to enter another road type. Landmark-worthy This penalty decreases the chance that Waze will route through a parking must be something of lot as a destination shortcut but allows better navigation in itself, either having and out of a well-known and documented name, or serving multiple destinationsparking lot. For information pertaining It is advised not to mix road types within a parking lot to using avoid triggering the Parking Lot Place please see: [[Places/Parking lot]]transition penalty unnecessarily.
==== Shopping Centers ====
*Main entrances from the roads outside the parking lot
*Lanes that run along storefronts
*Lanes that at the edge of the lot which run along main alongside public roads outside the parking area (to prevent cars prevents Wazers in the parking area from "snapping " to the main roads public road, and then sending incorrect speed informationit)*Primary travel lanes that serve to get people from one area of the lot to another
Remember, the goals here are usability and simplicity. When in doubt, imagine yourself in a car in the lot at various points, and ask yourself what the most efficient way would be to get to a store at the other end of the lot, or to exit the lot and get back on a main road, with as few convolutions as possible. The lanes that are used the most in this thought experiment should be mapped, with the rest being omitted. You can turn on the GPS points layer ([[Shortcut key]] Shift-G) to see where traffic has been most recently is concentrated to help determine get a sense of what might be the best section to mapneeds mapping.<br/>[[File:ParkingLotRoad ShoppingCenter.png|714px]]
In particular, '''do not''' map every single lane, and especially not every single parking space (it has been done!). This serves no purpose but to clutter the map, confuse directions, and put an unnecessary burden on both the client and server hardware. Remember usability and simplicity are #1. Your editing time and expertise can be better used elsewhere in the map.
==== Small Parking Lots ====
Parking lots that serve a small number of businesses should be minimal: enough to give the driver correct directions into and out of the lot, and navigate to a particular business. Very small lots with a single one entrance/and one exit could even be represented by a single segment running diagonally across through the parking area (lots with entrances either a diagonal across the lot if it connects to roads on both sides) each side, or a single, flattened curve (for strip mall-style lots that only have with entrances/exits and exit along a single the same road, such as for strip malls).
Beware of Parking Lot exits that have To permit a restricted turn (typically no left turn allowed across route to be given to exit a median). Due to small parking lot from the same point the way that Waze routing works in regards to penaltiesparking lot was entered, if there is only one way out of a Parking Lot Waze [[Turn_restrictions#U-turns|u-turns]] may route you to take that restricted left turn. In these cases it would be better to provide another path out enabled at the ends of the parking lot road. This is particularly relevant where a single parking lot via an unrestricted turnsegment connects two different street segments such as is common for many corner [[Places/Gas_Station|gas stations]].
==== Drive-Through Lots ====
Because these lots can be narrow and congested, with one-way sections, the simplest way to represent them may be as just a one-way drive-through loop. ''Caveat: because both ends of a segment cannot connect to the same junction, if the lot has only one entrance/exit, it is necessary to build the [[Junction Style Guide#Loops|loop using three segments]].''
==== Use Two parking lots connected to the same street ==== Bad routing can occur when two parking lots connect to the same street. This can happen, for example, where two lots face each other. If you connect both parking lots to the street using ''the same junction'' as the connection point for both, Waze will treat them as one parking lot.  If there are no turn restrictions preventing routing across the street, Waze may route the driver through one parking lot to reach a destination in the other parking lot. Waze is designed to avoid such routes, but in this configuration, Waze does not apply the expected penalty - because crossing through the junction from one parking lot segment to the other is not considered a transition, even though there is also a street running through the junction. This may be most easily understood by looking at the example image below. If it is not legal to cross from one lot to the other, [[turn restrictions]] will prevent any sort of routing between the lots. However, if it is possible to route from one lot to the other, then a different method is required to prevent routing through one lot to reach the other.  To be sure that Waze will apply the transition penalty when routing through one parking lot from another, the two parking lots must be isolated from the each other such that passing from one to the other requires driving over a standard road segment (not a parking lot road or [[Private road|private road]]). You should use a short "stub" length no less than {{:Segment length/Minimum}} of a standard road segment. This segment will run from the junction to the entry/exit segment of one of the lots. With this configuration, exiting the parking lot will have a consistent penalty, whether the route exits the first parking lot to the street or the route leads to another parking lot at the same junction. The short stub may reduce display impact and will also signal other editors that the use of a different road type is not accidental. Parking Lot Road Type lots do not have to be across the street from each other. In a strip mall, if the exit segment of one business is joined to the entrance segment of the next business, the same problem can occur. ===== Illustration ===== For example, in the configuration shown below if routing from the west parking lot, there is no transition penalty to route through the gas station parking lot on the east side of the street if routing east on Riva Rd. Conversely, if routing to the west parking lot from Riva Rd. there is no transition penalty to use the gas station.  [[File:PLA.png|center]] {{clear}} 
The Parking Lot Road type exists to allow the mapping of [[File:PLB.png|right]]This potential problem arises when two parking lots, while discouraging on opposite sides of a street connect at the same junction node on the street.{{clear}}[[File:PLC.png|right]]If this configuration causes routing server from using them for navigation vs. problems it can be solved by changing the road networktype of one (or both) of the parking lot roads that intersect with the street.

Every the crossover segment that is used to map a parking lot should may be of changed (this may also allow [[U-turn_prevention#Avoiding_U_turns|U-turns]] at the Parking Lot crossover segment type. It is advised not to mix road types within a parking lot).
