Google presently accepts 2 specific types of network data: New roads, and bicycle and pedestrian paths. Keep these things in mind:
- Use a segment-based representation. A segment is part of a road between two intersections. We can not accept roads that have multiple intersections hanging off of them.
- The street format is similar in many ways to the address format, only with different street number format.
- All address ranges should be specified relative to the the geometry (that is, the right side is to the right of the path from the start of the segment to the end of the segment).
| Field | Description | Example values |
|---|---|---|
| ID | A unique and stable identifier for the road segment | Any alphanumeric string (e.g. "14232514") |
| AR_RT_FR (optional for BP) | Starting address on right hand side, relative to geometry | 42 |
| AR_RT_TO (optional for BP) | Ending address on right hand side, relative to geometry | 58 |
| AR_LT_FR (optional for BP) | Starting address on left hand side, relative to geometry | 41 |
| AR_LT_TO (optional for BP) | Ending address on left hand side, relative to geometry | 57 |
| ST_NAME | Street Name and Type (the words Street, Avenue, etc., can be abbreviated) | Powell St |
| ST_NM_A1 (optional) | Alternative Name 1 | U.S. 101 |
| ST_NM_A2 (optional) | Alternative Name 2 | |
| NEIGHBH (optional) | Neighborhood Name | Union Square |
| CITY | City Name | San Francisco |
| STATE | State (Two Letter Abbreviation) | CA |
| ZIP (optional for BP) | 5-digit zip code | 94108 |
| CNT_NAME (optional) | County Name | San Francisco |
| CNT_FIPS (optional) | County code (see here and here.) | 06075 |
| ONEWAY (optional for BP) | One-wayness - relative to the direction of geometry | "None", "To-From", and "From-To" |
| PRIORITY (optional for BP) | We would consider the following levels: interstate, federal/state highway, expressway, minor arterial, local, not intended for public traffic. | minor arterial |
| LANES (optional) | Number of lanes | 2 |
| SURFACE (optional) | Road Surface | Paved or Unpaved |
| SPEED_LM (optional) | Speed limit in MPH | 55 |
| AVG_SP (optional) | Average Speed | 25 |
| CAR (optional) | Cars are allowed on this segment? | Allowed, Small vehicles only (mopeds etc), None, Disallowed |
| PEDEST (optional) | Whether the segment allows bikes, and if so, what type it is | One of: Trail, Walkway, Mall, Sidewalk, Wide Shoulder, None, Disallowed |
| BIKE (optional) | Whether the segment allows bikes, and if so, what type it is | One of: Trail, Bike Lane, Wide Shoulder, Recommended, None, Disallowed |
| SEPARATED (optional) | Whether the road is separated by a barrier in the middle | Y/N |
| TURN_R (optional) | Turn Restrictions (or see below for exact format) | Freeform text |
| ELEVATION (optional) | If the road is elevated, or a bridge or a tunnel | One of: bridge, tunnel, overpass, underpass |
We are happy to accept turn restrictions as freeform text to make it easier for people to submit data as turn restriction formats can be very complicated. We can accept turn restrictions in any format. However, to assist, here is a model format that would typically be delivered as a CSV file or a DBF file:
|
Field |
Description |
Example |
|
FROM_ID |
The ID (see the id column above of a road segment) of the segment where the turn restriction starts |
14232514 |
|
FROM_END |
The end of the segment the turn restriction applies to relative to its geometry. |
Either "FROM" or "TO" |
|
TO_ID |
The ID (see the id column of a road segment) of the segment where the turn restriction ends |
14232599 |
|
TO_END |
The end of the segment the turn restriction applies to relative to its geometry |
Either "FROM" or "TO" |
|
MODE |
The mode of transportation the limitation applies to. |
Either "ALL", "PEDESTRIAN", "CAR", "TRUCK", "BUS" or "NON-HOV" |
|
START_TM |
The start time of the turn restriction, in 24 hour notation. Leave this and END_TM blank for permanent restriction |
06:00 |
|
END_TM |
The end time of the turn restriction, in 24 hour notation. Leave this and START_TM blank for permanent restriction |
10:00 |
|
TYPE |
Type of turn restriction |
Either "NO LEFT TURN", "NO RIGHT TURN" or "NO U-TURN" |
