8. Section Control on Austrian motorways Objectives » Harmonization of traffic flow » Surveillance of closed lanes » Detection of wrong-way drives (’ghost cars‘) » Image triggering for vehicles exceeding height limits » Detection of stolen vehicles » Traffic surveillance » Statistical data » Monitoring different speed limits

11. Section Control on Austrian motorways Average speed: Before/After

12. Section Control on Austrian motorways Costs/Benefits Costs of the measure » Investment costs » Annual costs of operation and maintenance Economic benefits » Reduction of accident costs (numbers, severity of injury) » Reduction of road traffic emissions

13. Section Control on Austrian motorways Costs of the measure

14. Section Control on Austrian motorways Accident history » Reduction in total numbers of casualty accidents and severity of injury » since August 2002: no fatal accident recorded

15. Section Control on Austrian motorways Safety effects » Comparison ’Current situation’ vs. ’Anticipated situation without SC’ » Control group: development of accidents on motorways

16. Section Control on Austrian motorways Valuation of environmental impacts » Emission model by the Austrian Umweltbundesamt » Input factors:  vehicle type (passenger cars, lorries)  speed during day/night  changes in composition of vehicle fleet

17. Section Control on Austrian motorways Speed violations and charges » Aug.03 – Sept.04: more than 29 million vehicles measured » 40.881 drivers charged because of speeding Every 700 th driver (0,14%) does not follow speed regulations (?) » mutual recognition of financial penalties only with D, CH

19. Section Control on Austrian motorways Conclusions » Positive safety effect despite low accident rates  Accident rate in the Kaisermühlen Tunnel: 0.10  Austrian average on motorways: 0.12 » CBR would be higher if material damage accidents and foreign speeders were included » Stronger effects on road sections with above-average accident rates » CBA incorporates various effects (not only safety effects) into evaluation process » Results from this CBA can not be generalised but refer to a specific situation (Kaisermühlen Tunnel).
