Mobile applications for traffic safety

This paper describes Centria´s research work on improving traffic safety and traffic flow by developing mobile applications to support real-time decision making. Centria has utilized a wide range of mobile device built-in capabilities in the mobile applications it has developed. For example, Wi-Fi has been used for vehicular area networking, 3G/4G/LTE for vehicle-to-infrastructure (V2I) communication, and Bluetooth for acquiring OBD2 information. When all these functionalities are connected into one single device with an adaptive dashboard, we have a powerful tool for cognitive infocommunication (CogInfoCom) in the vehicular environment. Fully programmable additional user interfaces can provide two direction communication channels for the driver. Applications can make use of the data gathered from multiple sources and support driving events in an intelligent way through location awareness alerts and notifications. Because they are independent of vehicle technology, web-based HTML applications and mobile phone user interfaces guarantee the potential to reach a vast majority of people driving older cars in traffic. Applications developed by Centria will bring this old car fleet fully into the context of intelligent transport systems (ITS).
