Abbreviations

The following abbreviations should be used where possible to conserve screen space.

Road Name Abbreviation TTS Expansion?
Avenue Ave Yes
Boulevard Blvd Yes
Broadway Bdwy Untested
Close Cl Yes
Court Ct Untested
Crescent Cr Yes

Gardens Gdns Yes
Green Gn Untested

Terrace Ter Yes

Notes:

  1. Roads like "The Avenue", "The Green" etc should not normally be abbreviated.
  2. TTS = Text To Speech for future Waze version support in UK.

Road types

The following convention should be followed where possible, although it is acknowledged that you may need to deviate from it in some circumstances.

Waze Road Type UK Road Types
Freeway Motorway
Major Highway Trunk roads (other than motorways) as defined below.
Minor Highway Non-trunk A-class roads or dual-carriageway B-class
Primary Street Other B-class roads and roads carrying heavier traffic, often seen on Ordnance survey maps in yellow or orange.
Streets Urban Streets, Low traffic rural roads

Scottish Trunk Roads (Traffic Scotland)

English Trunk Roads (Highways Agency) | London Trunk Roads (Transport for London)

N Wales | Mid Wales | S Wales (Traffig Cymru)

Combined Map

Dual Carriageways

The following convention should be followed where possible, although it is acknowledged that you may need to deviate from it in some circumstances.


A road can be split into be 2 one-way roads if any of the following conditions are met:

  1. The central reservation is > 5m
  2. There's a visible gap between average of all GPS traces
  3. It is split by physical barrier (Concrete, Armco, pedestrian barrier etc)


Pedestrian refuges and painted road separation (cross hatching that can be driven over) should not normally be split. Be aware there are a lot of these that were created as split roads during the UK Base-map import, these usually need merging to be a single two-way road.

Motorway Carriageway Naming Convention

Whenever possible, on split roads, name carriageways with the direction of travel. Insert the direction of travel at the end of the road name:

Examples:
1. M1 (N)
2. A4 (W)
3. M25 (ACW)

This makes traffic and incident reports much more useful and helps with navigation.

Ramps (to/from Motorways and Dual Carriageways)

For the best balance between information, routing, reports and screen real estate the following convention should be used for the ramp road type:


Exit Ramps:

<Road Number> (<Direction>) (<Junction Number>) Exit (<” to ” Road Number 1, Road 2 …>)

Examples:
1. M54 (E) J4 Exit to A464
2. A46 (N) Exit to A6
3. M1 (S) J24 Exit to A453, A6
4. M1 (N) J24 Exit to A453
5. M4 (W) J4B Exit to M25


Entry Ramps:

“Entry to” <Road Number> (<Direction>) (<Junction Number>)

Examples:  
1. Entry to M54 (E) J4
2. Entry to A46 (N)
3. Entry to M1 (S) J24
4. Entry to M1 (N) J24
5. Entry to M25 (N) J15


Notes:

  1. Fields marked in parenthesis (<field>) are optional.
  2. Onward roads should only added if they are shown on road signage as this is an aide to the driver to confirm they have the correct exit (e.g. Exit ramp example 4 which also has A6 and A50 not on signage). [Hint: look on streetview]
  3. Roads with clockwise or anticlockwise directions (e.g. M25) should have have ramp directions taken from signage which will typically be N, S, E or W (e.g. Entry ramp example 5). [Hint: look on streetview]

Junction Naming

When naming/numbering junctions, particularly on motorways, please ensure the landmark is kept tight to the road system to ensure a tidy transfer to the client. The "snap-to" feature when adding landmarks via Papyrus should make this process easier!

or...


Large, freehand rectangles should be avoided...

Road Name & Number

Where a road exhibits both a road number and name the following convention should be used:

<Number> - <Name>

Examples:
1. A7 - Old Dalkeith Rd
2. A1 - Edinburgh Rd

This gives both a consistent appearance and allows a straightforward transfer if/when Waze UK moves to the official Department for Transport designations.

The same can also be said for adding the direction of travel on single/dual carriageways with an A-road designation in the form

<Number> (Direction) - <Name>

Examples:
1. A2 (W) - Dover Rd
2. A229 (N) - Cuxton Rd

Roundabouts

To aid navigation instructions, roundabouts should typically remain unnamed - where the client comes across a segment with no name it will use the next named segment as the next named instruction whilst retaining any turn signals.

Bypass or By-pass?

Bypass.
