Improving road and tunnel safety via incident management: implementing a video image processing system Video Detection Solutions Benjamin Schiereck, Sales Manger Traficon Germany
Introduction Incident Management: Video Based Incident Detection Basic Functions of Incident Management Video Image Processing Functions, Methodology & System architecture Detection rate Automatic Incident Detection system Cases (Eye on fire in a tunnel) Typical Freeway and Tunnel AVI files Summary Conclusions Outline of Presentation
Introduction More Secondary Accidents & Long Traffic Jams More Accidents & More Cars Involved SOLUTION? More Traffic Time INCIDENT MANAGEMENT
Traffic Monitoring, Prevention Incident Detection Incident Verification Driver Information Incident Clearing Basic Functions of Incident Management
Most important is safe infrastructure Monitor traffic situation, speed and occupancy using video cameras. Set appropriate speeds on VMS panels Fast information about the incident Fast reaktion on incident e.G.. Closing the Tunnel Traffic Monitoring – Prevention All about time
Traffic Monitoring on Highway using cameras!!
Access control, situation in the Tunnel Monitoring actions with video Slow driving vehicle Traffic jam in tunnel Speed differences Occupancy Intervehicle distances VMS Panels Ventilation control Traffic Monitoring in Tunnel
Detection Rate Incident Detection with respect to dedicated camera positions for incident detection Data collection for Outdoors Applications and for dedicated camera positions for data collection

Case 2: ORESUND - Situation • Because this is quite a long tunnel at under sea level, the owner requested a highly redundantsystem with a very high detection rate, high reliability (MTBF) and a very high level of service (% Uptime). • This was one of the reasons why the detection cameras were installed at 60 metres distance, but programmed to cover at least 120 m.

Summary Basic Advantages of Video Based Incident Detection: • Fast incident detection rate • Visual verification • High system reliability • Easy to install and modify • Low false detection rate & cost • Low overall lifetime cost
Video detection works reliable. Video detection is the fastest way to detect. Video detection has the lowest false alarms rate. Video detection offers immediate verification via CCTV. AID, Automatic Incident detection is the best detection method for Incident management Conclusions
Why use other incident detection if you will verify by video? Just use Video Incident detection Directly Thank You
