DIPLODOC - DIstributed Processing of LOcal Data for On-line Car services

DIPLODOC - DIstributed Processing of LOcal Data for On-line Car services project is to design and develop a system based on a distributed architecture where intelligent vehicles communicate with a remote traffic control center.

Each vehicle integrates different technologies to provide more comfort and driver safety. Speech recognition and synthesis techniques are used to interact with the user. Computer vision and image understanding are applied to the extraction of traffic parameters and to accident avoidance by detection and recognition of obstacles on the road using on-board stereo camera. Wireless telecommunication is used to send and receive traffic data and route planning information to/from the control center. The practical result of the project will be a simulation of the traffic control center and a demonstrative vehicle equipped with vision, speech and telecommunication devices.

The DIPLODOC architecture has been designed in order to satisfy four services, defined as follows:

  • xFCD (eXtended Floating Car Data): the vehicles act as mobile probes for the collection of remote data. Each vehicle transmits its position provided by the satellite positioning system and data coming from the engine control unit and from the on-board vision system. Moreover, still images are sent to a specialized vision module hosted in the center for a deeper analysis. The system at the traffic control center exploits and integrates the information coming from the vehicle fleet in order to deduce the local traffic conditions.
  • xEC (eXtended Emergency Call): the user can activate manually or by voice an emergency call to the control center. The emergency call allows the operator in the traffic control center to be timely informed about the on-board situation. Extended information, like video sequences and audio recording, are sent in addition to the position data of standard emergency call.

  • DRP (Dynamic Route Planning): the driver can request by voice a route plan for the travel from the traffic center: how to arrive at a desired destination starting from the current vehicle position, considering also information about traffic levels on the possible paths.

  • FOR (Front Obstacle Recognition): this service aims at warning the driver when pedestrians, vehicles or obstacles are in close proximity to the driver’s intended path, using information coming from the on-board vision sensors, the vehicle sensor data, and possibly from environmental conditions or driver activity to modulate the alarm level.
