• report on the existing road accident potential
  for all kinds of road users.

RSI-CONTENT

• Routine Inspections and Inspections of Road Works
  (Annex III of the Directive)
• Inspections undertaken regularly by Competent
  Authority
• Frequency Inspections as needed for adequate
  levels of Road Safety
• Member States shall adopt guidelines for
  Temporary Safety Measures to Road Works
• Appropriate Inspection Scheme to assure Proper
  Application of Guidelines

19
i.e.

• Pavement Drop-Offs

20
The Principles of RSI (good practice)

• Elements of RSI represent risk factors for
  accidents
• Standardized activities to ensure inclusion of
  all elements in a objective manner
• Use Checklists at least initially
• For each element included a standardized
  assessment should follow based on 3 categories
• Traffic hazard that needs immediate action
• Element is deviating from accessible standards
  but no short term action is needed. FOLLOW UP.
• Element complies with accepted standards and in
  good condition

21
The Principles of RSI (good practice)
contd

• Document findings and propose safety measures in
  STANDARDIZED form
• Inspectors should be qualified for the job.
  Conduct regular meetings for experience and ideas
  exchange
• FOLLOW-UP of RSI findings. CHECK whether
  implemented or not.

Annex III

• Delimitation of Road Section
• Previous Reports on Same Sections
• Analysis of Accident Reports
• Number of Fatalities and Injuries in past 3 Years
• Set of Remedial Measures for Next (1) Year
• Removal/protection of roadside obstacles
• Speed limits and Enforcement
• Visibility under various conditions
• Condition of Restraint Systems

24
Annex III contd

• Condition of Road Markings, Signs and Signals
• Rock falling
• Pavement roughness
• Set of Remedial Measures for more than one Year
• Redesign of Restraint Systems
• Median protection
• Overtaking
• Intersection Improvement
• Alignment Improvement

25
Annex III contd

• Amendment of Cross-Section
• Traffic Management and Control System
• Consideration of Vulnerable Road Users
• Upgrading to Current Design Standards
• Pavement Restoration and Replacement

26
Cost of RSI

• Varies considerably depending on road category
  and safety element
• On average 600-1000 / motorway-km
• 10-15 km / man-day

Road Safety InspectionRoad Safety Inspection of
Austrian motor- and expressways

• In Austria, Road Safety Inspection of motorways
  and expressways started in July 2003. - 2003
  and 2004 11 inspected sections
• - 2005/2006 10 sections

Road Safety InspectionRoad Safety Inspection of
Austrian motor- and expressways

• RSI in a team including
• accident analysis accident map
• analysis of the traffic conditions
• analysis of the constructional elements
• inspection on-site visit
• meetings and interviews with motorway maintenance
  unit and traffic police
• analysis of road surface (pavement rating - ruts,
  friction, )
• analysis of road maintenance measures
• analysis of road environment

remedial measures (short-, medium-, long term)
