RONCALLI - Real time traffic information

The RONCALLI principle is based on linking centrally available information with current vehicle data. Key components from RONCALLI are GPS-positioning (later Galileo) and traffic relevant information from a central server which communicates with amobile device (PDA) over a GPRS connection. The permanent availability of positioning signals from satellites and efficient mobile radio connections form the central theme of the project.

Short Description

In order to present the most up to date information, RONCALLI receives constant updates of accident spots, sensitive zones (around schools), road conditions, and speed limit information (Intelligent Speed Adaptation).

In the frame of the project RONCALLI, this information brought together from a myriad of sources will be specially processed for each individual participant according to their current situation and made accessible via a standard traffic safety service device. Special value is placed on aspects of road safety, customer friendliness, and information reliability.

By the successful implementation of RONCALLI, the consortium has proven that road safety information can be made available in real time to each participant and that this does not necessitate the development of special hardware, rather existing standard business equipment can be used. RONCALLI provides a leading contribution to road safety in Austria which represents an increase in value for the consumer as well as for the entire economy.
