Researchers at the Polytechnic University of Valencia tell us about the latest release of their app Driving Styles.
Alert the driver in real time when their driving becomes aggressive. Keep track of fuel consumption, CO2 levels and the money spent for each journey. Find out what areas of the city cause drivers the most stress, individually and collectively. These are the main features of the latest version of Driving Styles, an app developed at the Universitat Politècnica de València (UPV), with over 5000 downloads to date.
Driving Styles uses Bluetooth technology to extract data on speed, fuel consumption, revs, acceleration, etc. from the vehicle’s electronic control unit. Connecting via the OBD-II diagnostics port, fitted as standard in cars manufactured after 2000, the device then processes this information and instantly sends it to the user’s mobile phone. This new version also incorporates the use of heart rate monitors and smartwatches.
Juan Carlos Cano and Carlos M. Taveres at the UPV’s Networking Research Group (GRC) tells us that the application brings together all of the data in real time – the data from the vehicle, from the heart monitor and smartwatch – and records it with the corresponding time and location tags.
Meanwhile, the smartphone processes the data using neural networks to analyse the driver’s behaviour behind the wheel, classifying their driving style as either calm, normal or aggressive based on percentage scores. If the app detects dangerous driving patterns, users receive an alert in real time to their mobile phone. The app can even sound an alarm via their mobile device or smartwatch.
At the end of the journey, the full stats can be reviewed, sent to the web server for storage and further analysis.
Driving Styles Web
Driving Styles also has a website where drivers can view their routes in more detail, along with an overview of all journeys and overall driving style classification. «Users can consult all of the information collected, presented in the form of detailed graphs charting accelerations and speed, as well as maps of the routes taken. It also includes personalised analysis of behaviour behind the wheel, fuel usage, etc.» (Cano and Tavares).
What’s more, the global database of all drivers managed at the UPV will allow comparison of driving styles between countries, as well as detection of the areas in each city that cause drivers the most stress.
«With this latest version we wanted to go a step further: our goal is to contribute to driver safety, while also enabling a more efficient and cost-effective driving style among our users, providing them vital information in real time», the researchers conclude.
