ITS (Vienna 2012) was the first presentation of the Testfeld Telematik project. Besides TomTom, companies like Kapsch, Asfinag, Siemens and Swarco are part of the consortium. The project improves knowledge and implementation towards a future with real-time (traffic related) information between infrastructure and vehicle. This to raise safety, efficiency and environment friendly mobility.
Problem
TomTom delivered a tablet with the TomTom (development) navigation platform. It is extended with an interface to visualize dynamic speed signs, (re)direction signs, greenwave, trafficlight countdown (etsi: SPAT + TOPO standards), park, ride and flight information. The tablets use a Kapsch WiFi-p gateway (802.11p) to receive messages from the infrastructure. The infrastructure broadcasts messages coming directly from the Vienna Traffic Center. The received messages are visualized and if possible any delays or closure are injected in the navigation engine to provide an optimized route and better estimated time of arrival to the user.
Solution
The platform runs on Android and we have developed several Android services to handle all information: Bluetooth communication towards the gateway, visualization service which renders composed images, the logging service, a survey widget and the main application that verifies if a message should be visualized or otherwise handled at the current location.
Every tablet gives feedback to the back-office of TomTom, therefore we developed several J2EE applications (running on JBoss) that handle this feedback, e.g. location of the device, logging of visualized messages and the answers to the user survey that can be filled in after each trip.
