Road Status

Road Status is still in its early stages of development, but you can already see bits and pieces inside your Private Cyberspace (from road speed limits inside community maps to voice interfaces for those on the move).

1. Voice Interface

If voice interfaces in car are more accurate and flexible than the use if touch screen can be much reduced.

The voice interface in your Private Cyberspace is trained exclusively by you so can be close to 100% accurate, allowing you to keep eyes on the road and hands on the wheel. Studies have shown that touch screens are much worse than driving above the drinking limit.


Besides driving a private and accurate voice interface can also help when walking and running along the road, the hands are more free and there is less need to look down on the phone.

2. Speed Limit

The privacy protection provided by your Private Cyberspace mean you can query the latest up to the minute speed limit of your stretch of road WITHOUT disclosing your location to others and get notifications anonymously if you have exceeded the speed limit.

Ringtone Notification is especially helpful to drivers of old vehicles that do NOT have access to voice based speed limit warning (which automatically gives out a warning when the car has exceed speed limit).

This not only help drivers of old cars, but also passengers of commercial vehicles monitor speed of their travel.

Speed limits are available in most community maps e.g. in NSW Australia where streets without labels are set with a "default speed limit" of 50 km/hour.

Currently the global openstreetmap database for road speed limits.

2.1. Open Data Programs

Background speed limit data are normally available from governments through their open data programs e.g. the NSW Australia road speed limit data is available for free at Speed Zones | TfNSW Open Data Hub and Developer Portal It is provided as a Shapefile which can be read using the free QGIS program:

2.2. User Updates

An advantage of using a community map is that you can update those government open data sourced speed limit at any time!

If you spotted an error or a change in the speed limit you can fix it directly using the inbuilt editor at
For example:
the value to change for a road is "maxspeed":

Or if you are really keen you can perform a bulk upload of speed limits (e.g. using shapefile) with the free JOSM software.

Large shapefiles needs to be reduced in size first and Import Guidelines must be followed.

Recommended steps for Bulk Uploads:

  1. Create a wiki page YourUserName/ImportName with all the info about your import (e.g. how you plan to merge your data).
  2. Create OSM file using JOSM including converting, reviewing and adjusting.
  3. Upload the OSM file on public server (not to real openstreetmap yet), and link to it on the wiki page.
  4. Send a message to the imports mailing list pointing to the wiki page.
  5. Wait for feedbacks and adjust OSM file taking all feedbacks into account.
  6. Upload OSM file.
