The Problem

SOLUTION APPROACH BY E.C.


Four Approach Schemes

RSI- Paris Definition of 2007

Road safety inspection is
– a formal systematic road safety
assessment of road or road scheme
carried out by
– an independent, qualified inspector or
team of inspectors who
– report on the existing road accident
potential for all kinds of road users.

RSI: Some Clarifications

• NOT ONLY ON BLACKSPOTS
• MANDATORY ON TRANS-EUROPEAN NETWORK

• Any reason not to apply it on the
rest of Road Network?

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

i.e.

• Pavement Drop-Offs


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


The Principles of RSI (good
practice) cont’d
• 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


Annex III cont’d

– 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


Annex III cont’d

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


Cost of RSI

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


EU Experience

How?

By any means …
– Visually
– Instrument driven
– Automation Recording and Evaluation Techniques

CASE EXAMPLE:


Road Safety Inspection
Road 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

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)
