The Drivaware server software acquires the data sampled by the on-board probes. The data are stored in a central database so that they can be viewed and processed at any time. The probes usually send a block of data once every minute.

Currently, the system acquires data such as vehicle speed, GPS position, engine speed, engine temperature, fuel rate, and many others, which are called channels. Probes can send channels in raw form (sequence of samples) or in a synthetic form (such as min/avg/max, distributions, etc.).

Data Visualization

The current server's software allows to view the data in charts and map, as shown in these figures.


The first figure shows the map of Milan with the vehicle's course. The second figure displays a sample chart of the vehicle speed and CO₂ emissions.

The system allows to draw charts and maps of all the acquired data; the vehicle course can be drawn using a color scale based on the data values.

This approach allows to view detailed information on every vehicle duty cycle, enabling to identify relevant information and therefore adjust, when needed, the acquired data channels.

The system is also able to perform automated analyses, as explained in the data analysis section.

Data Download and Exchange

The system allows to download the acquired data in CSV or XML format, so that it can be processed with 3rd-party applications such as Microsoft Excel or Mathworks Matlab, as well as custom-built applications.
