5European 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
6European 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

8What 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
9RSA ? 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
10RSI 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 .
11RSI 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

13Why 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
14Why 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

16Who 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
17Who 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
18Who 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

20How 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
21Preparation 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
22Preparation RSI (2)
Road safety map of Utrecht
23Preparation 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
24RSI 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)
25Inspection 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
26Ideal road network
27On 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
28On 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)?
29On 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
30On 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!

35Frequency 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?

37RSI 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!

- 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

- 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
42What to do tomorrow
- Selection/training inspectors
- Certificated inspectors
- Regularly come back and renew knowledge
