Ratio (CBR)
Components of the CBA Benefits Costs
Road traffic emissions 79,108
Accident costs 1,025,903
Installation and maintenance costs 207,949
Total 1,105,011 207,949
? ROSEBUD (WP1) CBR gt 3 are ranked excellent

Section Control on Austrian motorwaysConclusions

• 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).
