This content will enable users of the software to create a range of products and features that can enhance driving safety, such as speed advisory warnings (done visually or aurally). Navteq claims these applications will help reduce inadvertent speeding, avoid fines and improve driving performance.
"Australia has been on the leading edge of road safety globally for many years," said Kirk Mitchell, director of business development, NAVTEQ Australia. "The team worked tirelessly to capture this advanced speed limit data at the quality level required to enable such safety applications, because we recognised this as a critical requirement by the Australian business and consumer communities." 
Navteq has already collected data on railway crossings, school zones, country/town entry point speed changes and accident black spot data. All of this data is layered on the company's navigable database needed for dynamic turn-by-turn routing.
