1. Scenario  Emergency vehicle  Free way  Fast and Safe Public University of Navarre Ontology Based Road Traffic Management A. J. Bermejo, J. Villadangos, J.J. Astrain, A. Córdoba 3

2. State of Art  Plenty of projects  No solutions ◦ Dangerous scenarios  Too basic solutions ◦ Alternative routes ◦ Alarm signal forwarding ◦ Basic movements Public University of Navarre Ontology Based Road Traffic Management A. J. Bermejo, J. Villadangos, J.J. Astrain, A. Córdoba 4

3. Solution  Distribute vehicles  Minimum alteration in traffic flow  System characteristics ◦ Small areas ◦ Distributed system ◦ Collaboration ◦ Fast decision taking ◦ Individualized solutions Public University of Navarre Ontology Based Road Traffic Management A. J. Bermejo, J. Villadangos, J.J. Astrain, A. Córdoba 5

3. Solution  ONTOLOGY ◦ Decision taking system (SWRL rules)  Positions and speeds ◦ Real-time solutions (Jess reasoner) ◦ Consensus ◦ Strategy  Vehicles to slowest lane  Gaps assignment Public University of Navarre Ontology Based Road Traffic Management A. J. Bermejo, J. Villadangos, J.J. Astrain, A. Córdoba 6

3. Solution  System Architecture 2 1 Solutions: - Accelerate - SoftAccelerate 3 - Decelerate - SoftDecelerate - MaintainSpeed - MaintainDistanceWithCarInFront - ChangeLane Public University of Navarre Ontology Based Road Traffic Management A. J. Bermejo, J. Villadangos, J.J. Astrain, A. Córdoba 7

4. Conclusions  Real-time solutions (300 ms)  Drivers: ◦ No indecision ◦ Straightforward execution ◦ Common sense  Continuous monitoring  Other approaches: ◦ Objects on the road ◦ Reduction in number of lanes (traffic controls, road works, accidents,...) ◦ Car accidents Public University of Navarre Ontology Based Road Traffic Management A.

5. Future steps  Standardized ontology (A3ME)  Complex scenarios  Infrastructures  Atmospheric conditions Public University of Navarre Ontology Based Road Traffic Management A. J. Bermejo, J. Villadangos, J.J. Astrain, A. Córdoba 9
