Accuracy and bugs

Speed Adviser uses Intelligent Speed Adaptation (ISA) technology. The speed zone maps used in the ISA smartphone app are based on TomTom and Transport for NSW map data. We strive to keep the maps accurate, but errors may still occur.
If you find an error in a speed zone, please record its location. After you arrive at your destination, email us about the error. If you find a technical bug, or can suggest an improvement for the app, please email roadsafetytechnology@transport.nsw.gov.au.

Power use

Speed Adviser needs a lot of battery power, so we recommend you always use a car phone charger.

Data use

Map information is stored on your phone, so the app does not need to download data when it is working.
