Section Control on Austrian motorways System description

Section Control on Austrian motorways Objectives » Monitoring different speed limits » 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

Section Control on Austrian motorways Average speed: Before/After

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

Section Control on Austrian motorways Costs of the measure

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

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

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

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

Section Control on Austrian motorways Cost-Benefit Ratio (CBR) Components of the CBA Benefits Road traffic emissions 79, 108 Accident costs 1, 025, 903 Installation and maintenance costs Total Costs 207, 949 1, 105, 011 207, 949 ROSEBUD (WP 1): CBR > 3 are ranked „excellent“

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 » Stronger effects on road sections with above-average accident rates » CBR would be higher if material damage accidents and foreign speeders were included » 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).
