European Directive (1)
  • Road safety inspections contain
  • periodic inspections of the road network on the
    road safety of the traffic flow
  • surveys on the possible impact of road works on
    the road safety of the traffic flow
  • Member States shall ensure that periodic
    inspections are undertaken by the competent entity

6
European Directive (2)
  • Inspections shall be sufficiently frequent to
    safeguard adequate safety levels for the road
    infrastructure in question
  • Member States shall adopt guidelines on temporary
    safety measures applying to road works. They
    shall also implement an appropriate inspection
    scheme to ensure that those guidelines are
    properly applied

What is a RSI ?
  • A road safety inspection is
  • a regular, systematic on site inspection of
    existing roads covering the whole network and in
    case of road works
  • conducted by trained teams of experts
  • to identify hazardous conditions and deficiencies
    that may lead to (serious) accidents, resulting
    in a formal report
  • RSI is also a tool within Network Safety
    Management
  • an essential tool for preventing possible dangers
    for all road users, including vulnerable users

9
RSA ? RSI
Remark RSA and RSI are in large extent based on
similar procedures and checklists
  • RSA stage 1 preliminary design
  • RSA stage 2 building or detailed design
  • Road will be (re)constructed
  • RSA stage 3 pre-opening audit
  • RSA stage 4 after opening audit
  • RSI periodical inspections

10
RSI and daily maintenance
  • It is very important to distinguish two types of
    inspections
  • Daily maintenance inspections
  • Road safety inspections
  • Daily maintenance inspection is a daily review
    where the infrastructure is reviewed and asap
    remedied
  • potholes,
  • damaged traffic signs,
  • broken down traffic lights,
  • overhanging branches .

11
RSI and daily maintenance
  • Daily maintenance inspection is network
    management from day to day
  • carried out by a road inspector
  • road inspector has not
  • an independent status,
  • a broad safety focus,
  • detailed skills for safety inspections
  • Both type of inspections form a part of the total
    management process and practice

13
Why RSIs? (1)
  • To evaluate road sections in operation
  • to identify safety hazards which affect any type
    of road user
  • to suggest measures to eliminate or to mitigate
    problems
  • possibility to focus on special problem areas
    pedestrians, road sides, intersections, ..
  • Pro-active and re-active approach of road safety
  • RSI is a tool within road network safety
    management. Objectives are
  • to prevent (serious) accidents
  • to keep the consequences of accidents to a
    minimum
  • to avoid expensive remedial work

14
Why RSIs (2)
  • Causes of road accidents
  • human factors 95
  • road factors 16
  • vehicle factors 6
  • The way in which the road itself influences the
    road user is crucial
  • accidents occur because road users fail to cope
    with their road environment
  • their ability to cope can be influenced by basic
    design factors
  • infrastructure not only influences accident
    prevention but also injury mitigation

16
Who will perform a RSI (1)?
  • The aim is to build teams of road safety
    inspectors under justification of a competent
    entity
  • the process / protocol of inspection
  • the inspectors have the necessary up-to-date
    knowledge
  • A team of at least two road safety inspectors
  • independent of the road administration
  • not involved in design / construction
  • supported by the road inspector

17
Who will perform a RSI (2)?
  • Requirements of a road safety inspector
  • relevant experience or training in road design,
    road safety, traffic engineering and accident
    analyses
  • an initial training road safety inspector
    resulting in a certificate of competence
  • take part in periodic further training courses

18
Who will perform a RSI (3)?
  • Team of inspectors with up to date knowledge of
  • road safety and road design
  • human factors / traffic psychology
  • enforcement / police
  • civil engineering (asphalt expert)
  • Alternatives meetings/interviews relevant experts

How to do RSI 5 steps
  • Preparation by desk research
  • On site inspection
  • Draw up the report
  • Follow up, implementation of measures
  • Check if everything has been done

21
Preparation RSI (1)
  • Investigations of accident data (3-5 years
    preceding RSI)
  • Traffic data
  • (intended) road function
  • traffic volumes (AADT)
  • specific groups of road users
  • Drawings of the section
  • Additionally data
  • speed data
  • experience police
  • complaints residents / road users
  • maintenance schemes/practices

22
Preparation RSI (2)

23
Preparation RSI (3)
  • The identification of road sections with high
    accident concentrations
  • high risk sites
  • Network safety management
  • A rough analysis of accidents can
  • provide guidance in terms of priorities
  • simplify the inspection
  • Rough analysis of accident data means
  • types of accidents
  • locations of accidents

24
RSI where to start?
  • High risk sites and/or high accident rates
  • E-roads are mostly very important international
    roads
  • Thinking in three road categories
  • a through road has priority above a distributor
    road
  • a distributor road has priority above an access
    road
  • Traffic volumes (AADT) within a specific road
    category
  • Road sections where an improvement of
    infrastructure is expected to be highly efficient
    (highest benefit-cost ratio)
  • Maintenance works (rehabilitation asphalt)

25
Inspection safety principles
  • Functionality of roads prevent unintended use of
    infrastructure
  • Homogeneity prevent major variations in mass,
    speed and direction
  • Recognisability of road design and predictability
    of the road course prevent uncertainty for road
    users
  • Forgivingness of the physical surroundings free
    recovery zones, passive safety of objects

26
Ideal road network
27
On site inspection time
  • Time of inspection
  • during daytime and at night
  • different seasons (snow)
  • By car, bike or feet
  • depends on the type of accidents
  • depends on the kind of infrastructure
  • the road needs to be seen from the road users
    perspective

28
On site inspection questions
  • How will all road users cope at all times and in
    all conditions with this road environment?
  • All dimensions are correct?
  • Does the design create confusion?
  • Is there too much or too little information?
  • Is there too little or too much visibility?
  • Does the lay-out or actual condition create
    hazards or obstacles to road users (forgiving
    roadsides)?

29
On site inspection tools
  • Test the design against the up to date
    guidelines is important, but
  • given the local circumstances, what is the best
    solution
  • therefore an inspector needs to have experience
  • Take pictures and / or video of findings /
    problems
  • Use of checklists is recommended

30
On site inspection checklists
  • To be used as a tool, an aid at the end of the
    process
  • to ensure that no major potential safety issue
    has been overlooked
  • To structure the performing of the inspection
  • checklist per problem area better than general
    checklist per road category
  • To provide points of particular interest
  • but
  • Expertise, knowledge and experience of the
    inspectors are most crucial to do the inspection!

35
Frequency of inspections
  • RSI will become (in future) more or less a
    routine process
  • Cross section, alignment and intersections will
    not change during some years, but have to be
    adapted to
  • changing road functions
  • traffic volume changes
  • rehabilitations of surface (win-win situation)
  • Road safety inspections every 2 to 4 year
  • monitoring of measures of previous inspection
    will automatically happen
  • Special elements changes (renewing guardrails)
  • inspections at irregular intervals?
  • preparation of the building design?

37
RSI report performance (1)
  • Carry out inspections day after day
  • first day inspection
  • second day report the results
  • third day inspection
  • Use photos to support the presentation of
    inspection results
  • Very important to indicate accurately the
    location of the problems
  • RSI-report is always negative!

38
RSI report content (2)
  • Part 1 project data, a brief description of the
    project
  • Part 2 brief description of the problems
  • positive and negative effects
  • the relative importance of each problem should be
    indicated (high, average, low).
  • Part 3 proposals of counter measures

39

What to do tomorrow
  • Continue with your preparing work for RSI
  • Set up of competent entity
  • Draw up a protocol/guideline
  • The steps to be followed and the elements to be
    considered
  • Use available literature, guidelines,
  • Decision process of different issues
  • Combining with daily (maintenance) process
  • Frequency of safety inspections
  • Prioritising of roads

42
What to do tomorrow
  • Selection/training inspectors
  • Certificated inspectors
