Highlights
Road Safety Audit (RSA) is defined as a formal examination of road planning, design, construction, and operation to identify potentially unsafe features.
The goal of RSA is to ensure the highest practicable standard of traffic safety for all road users.
A safe road has appropriate horizontal and vertical alignment standards suited to its environment.
Road cross-section should have appropriate lane and shoulder provisions for various traffic volumes.
Access control should be consistent with the road's function in the overall road network.
Clear and uncomplicated intersections with appropriate traffic control are essential for road safety.
Traffic signing should provide clear advice, warning, and unambiguous directional information.
Consistent delineation of the roadway and high standards of skid resistance and pavement drainage are crucial.
Appropriate street lighting and overall traffic management are key components of a safe road.
The RSA process involves seven steps, including preparation, site inspection, and deciding on required actions.
RSA is most effective when conducted at five key stages of highway development: feasibility, draft design, detailed design, pre-opening, and post-opening.
The feasibility and planning stage is critical for identifying safety implications of overall project concepts and road network safety.
Draft design stage focuses on functional design, access control, and safety for vulnerable road users.
Detailed design stage examines geometric design, road markings, and street furniture for safety compliance.
Pre-opening stage involves site inspections to ensure safety before the project opens to traffic.
Post-opening stage audits focus on identifying and correcting potential hazards on existing roads to prevent accidents.
RSA guidelines were first published in 1997 by the Public Works Department of Malaysia.
Audits during construction should ensure traffic management safety and compliance with construction standards.
Stage 5 audits of existing roads are proactive, aiming to identify and correct safety problems before they cause accidents.
Day and night inspections are essential for Stage 5 audits to check visibility and adequacy of road markings and delineation.
The RSA process includes checks for special provisions for vulnerable road users such as pedestrians and motorcyclists.
RSA Stage 5 also evaluates the effectiveness of speed limit signs and the need for additional traffic calming measures.
Sharp curves in rural areas can be accident-prone; RSA Stage 5 suggests treatments like advisory speed signs and good delineation.

hello this video is is on road safety
audit which is to ensure that the roads
being constructed to the highest
possible safety for the road users first
we start with the definition and goal of
road safety ordeal road safety or D may
be defined as the formal examination of
the planning design and construction of
a road project and the characteristics
and operation of an existing road by
independent and qualified examiner's to
identify any potentially unsafe feature
or operational arrangement that may
adversely affect their safety of any
road user so the goal of road safety
audit process is to ensure that all road
projects and all existing rules are
capable of providing the highest
practicable standard of traffic safety
for all road users before we go into
road safety audit we like to discuss
what are the general attributes of a
safe rule well a safe road has standards
of horizontal and vertical alignment
which are appropriate to the environment
second road cross section with
appropriate ly linen shoulder provisions
catering for the various traffic volume
access control consistent with the
function of the road in the overall road
network and a clearly visible and
uncomplicated intersection with
appropriate traffic control providing
safe movement for all user groups well
but traffic signing with clear advice
positive warning and ambiguous
directional information and you create
an consistent delineation of the roadway
high standard of skip resistance
pavement with good drainage
appropriate street lighting and lastly
overall traffic management management
which properly considers the needs of
all road users so these are the general
attributes of a safe road what are the
objectives of route safety audit the
objective of the road safety audit is
first to identify potential safety
hazards on new road projects at the
appropriate stage so that they can be
eliminated or otherwise treated to
mitigate the adverse effects at minimum
causes second the identification of
hazardous features of an existing group
so that they can be eliminated or
otherwise treated before they become
accident prone locations that to ensure
that the safety requirements of all
users are explicitly considered in the
planning design construction and
operation of road projects and fourth to
reduce the overall to life most of a
route project to the community ok we now
talk about guidelines for road safety
audit road safety audit work started in
Malaysia in 1995 on selected existing
routes under the supervision of senior
road engineer and a road safety expert
from Australia which is Edward button
the team put together guidelines for
road safety audit that were first
published in 1997 on your right is the
guidelines which is published by the
public works department of nature in
1997 the procedure for road safety audit
involves seven steps as shown in the
slide first is the step 1 which is the
preparation of the audit brief the
appointment of the auditor and the
appointment of the independent Assessor
the second step is the assembling the
background information for the road to
be audited the plan to be audited and
other documents required body for safety
or did step three involved initial
meeting with the auditors and handing
over the plan and other documents for
the audit and also discussions and
arrangement for the site inspection step
4
if worth involve carrying out or doing
the audit and summoning the plan and
site inspection step 5
preparing the audit report
step 6 completion meeting presentation
and discussion of the audit findings and
finally step 7 is deciding on the action
required on the audit findings there are
five stages in the development of
highway for all projects at which it is
most appropriately to carry out the road
safety audit
Stage one which is the feasibility and
planning stage where there is planning
concept network adequacy Road hierarchy
step two is the draft design stage where
our se or ctod is carried out on the
functional design access control on the
vulnerable road users using two daily
route to be constructed injunction type
and others
Stage three involve the detailed design
stage where our city audit is carried
out on the geometric design road
markings street furniture landscape and
tear zones and others Stage four involve
the construction and pre opening stage
whereby the audit is carried out on the
traffic management during construction
site inspection and construction
compliances clear opening day and
nighttime inspir
and finally stage 5 is the post opening
stage where the audit is carried out on
the safety performance during the
defects likely be period or auditing of
an existing rule you now discuss on the
stage 1 which is a feasibility and
planning stage this is the police
recognized stage of the routes safety
audit which may not be always applicable
particularly on very simple projects or
those involving only minor improvements
such as road rehabilitation worlds it is
particularly desirable to audit on video
transport infrastructure projects and
planning and feasibility stage to avoid
commitments which in later stages have
unfortunate safety consequences at this
stage of the road city and it will
identify safety problems associated with
the overall concept for project the road
network safety implication group options
intersection and interchanges types and
locations this dish also will consider
the safety implications of strategy
issues such as access control and
provisions for various root user groups
such as pedestrian cyclist motorcyclists
heavy Trump and others which may need
special emphasis generally on a
particular part of a project this is the
checklist provided in the road safety or
the guidelines for stage 1 which is the
planning and feasibility stage so in
this slide shows the information
required for the ADI and the other items
which involve road network effects
general geometric standards outline
provisions for users with special needs
access control details environmental
consideration
lassic consideration of alternatives
this slide shows the land-use and
traffic management which is normally
considered during stage one this shows
what other land uses for the delivered
development in the area and the rural
network provider so at stage one we will
look at the land use and traffic
management Stage two of the road safety
or the end of the draft of luminary
State design station at the preliminary
design stage many of the traffic
engineering features of a road project
and establish most of this such as cross
section elements intersections and
interchange they are lean and create
carriageway they are traffic control
options vertical and horizontal
alignment standards have a mark effect
on the safety performance of a project
furthermore it is generally at this
stage that the right-of-way requirements
are finalized and if this is not
advocate it may lock in unsatisfactory
design features this slide shows the
preliminary for the rental and vertical
alignment of a road project some of the
issues during stage 2 design involve the
intersection design which there are many
safety issues involved so at this
particular stage consideration must be
made for the type of intersection to be
used particularly junctions which have
high traffic volume in the stage 3 of
the the road safety audit is the stage
where detailed design is being carried
out in carrying out the detail design
designers are continually made
balances of judgment in the selection
and application of standards and guides
to meet the specific site conditions
relevant to each particular project the
road safety audit at this stage will
test the design decisions made against
the road safety objectives and will
identify aspects in which safety has not
been given high enough waiting
compared to other competing factors it
will also identify potential hazards
resulting from adverse combination of
vertical and horizontal alignment or
from choosing a series of minimum or
maximum design criteria other
undesirable features associated the
final grading drainage and landscaping
design as well as those arising from the
price traffic signing traffic controls
and street lighting which will be
finalized in the detailed design stage
can also be identified at this stage of
audit this slide shows some of the
weakness of the design of an Junction
which is located just outside a curve so
in this particular Junction drivers have
difficulty judging the deceleration when
they cannot see the highway carriageway
or the location of the stop line so the
approach sight distance in this case is
very important to be considered and this
must be checked in the detailed design
stage this slide sourced the detailed
design of horizontal and vertical
alignment the horizontal and vertical
alignment should have a consistent speed
and sight distance standard the design
speed of the horizontal curve at the end
of the straight from the south in this
example would be carefully checked in
this case the relatively steep grave of
seven point two six percent would help
reduce vehicle speeds as the entered is
curved so while it may appear to be
substandard it could be satisfactory
in assignment this slide shows the lack
of a deceleration lane at this high
speed exit ramp which is which would be
a safety problem you can see in this
slide also know that the unprotected
no-go area is a hazard
place in appropriate high barrier type
of curve is being used and also the
right light poles or lighting poles in a
vulnerable area so these things actually
can be rectified
during the detailed design stage and not
a big construction stage stage 4 of this
road safety audit is the pre opening
stage audit at this stage involve site
inspection of a project both by day and
at night and or just prior to its
practical completion or just prior to
the opening of a new project to traffic
the auditors can now see the project in
three dimensions and including any
changes modifications with during
construction the actual placement of
items such as got rails traffic sign
angeles street lighting landscaping a
look in detail and particular emphasis
should be given to checking that the
respective needs of all our user groups
me desirable safety standards this will
be the last chance to make sure that the
project open to the traffic in the best
condition to provide safe and efficient
operation so the stage for audit
generally also includes the audit of
traffic management in and around the
world earlier during the period of
construction such auditing is usually
done as early as possible in the
construction piece and periodically
during construction as may be necessary
to cover changes to the traffic
management as the work progresses this
slide shows the traffic management
during construction
and you notice that safety barriers are
placed at the appropriate place
appropriate locations so that they can
ensure the safety of the vehicle passing
through this construction site
this light shows some safety
deficiencies which can be which can be
sent on located during the route safety
or the stage form for example on the top
picture or photo and improper gabriele
to obliterate to the bridge real
connection can be corrected during the
construction stage the cut real should
be constant or continuous instead of the
this photo shows which is discontinuous
and at the bottom picture shows the
bridge approach cut reel which runs off
the brush onto the embankment resulting
in a decree ground support for the post
if the vehicle the vehicles approach
this guardrail
it can easily be dislodge so a proper
placement of gradual is important and
this can can be can be shown after
inspection of the construction finally
for Stage five which is the road safety
audit of an existing Road road safety
audits are designed for also on the
existing routes regardless of them
having been audited during planning
design and construction Stage five type
audits of existing roads may include
sections under construction or
undergoing maintenance operations the
stage 5 or the attempts to identify and
correct potential hazards before
accidents occur due to them that it it
is more proactive rather than reactive
an audit at this stage will identify
safety problems we should develop due to
normal wear and tear
traffic operations it will also identify
hazards due to the way the landscaping
has matured such as trees and foliage
obstructing traffic signs or sight
distance being impaired inspections by
day and night are insane essential to
check-in adequacies in delineation and
visibility apart from any relevant plans
the auditor sure has available data on
the accident history along the road and
traffic laws so that a proper assessment
can be made all of the road safety
performance again the stage 5 audit will
particularly look at the way issue who
wrote user groups is the route from
their particular safety viewpoint this
slide and the following slides will show
the checklist for route safety or J or
the stage 5 among the checklist includes
vertical and horizontal alignment as
shown in this slide as well also the
checking and Oddie of cross sections
where the items are shown in this slide
the audit of intersection which includes
the site distances general layout
features which have the following items
as shown in the slide so these things
must be properly audited to ensure that
the existing road is also for expressway
and other interchanges these are the
checklist which is required for the
route safety or the stage 5 these are
the interchanges of appropriately
located and space and physiological
traffic management strategy for the
region so the note the situations of
incompatibility of mixing every
intersection and interchanges and on the
same route appropriate and consistent
standard of layout Java 3 exits at exit
n
and three Rams identify locations where
the provisions of salarians is
inadequate the start and end deepest of
auxilary lanes we check ram alignment
and lang is consistent with the speed of
traffic entering the RAM bearing in mind
deceleration refinements and lightly
cueing of vehicles at ram intersection 4
and also finally the sight distance
required for entry and exhibit points
for traffic signal in installations road
safety or the stage 5 checkers these are
the items that you should be checked
traffic signals are provided only where
warranted for safe efficient and
equitable management of traffic flow
provision of location and spacing of
traffic signal such a sensible traffic
management strategy signal installs are
operating effectively and efficiently
ensure that there is inadequate where
there is where there is inadequate
signal hardware whose safely control the
various traffic movements we should we
should ensure that the signal spaces are
a new field then the signal hardware and
filling providers you create also for
pedestrian and other vulnerable road
users
finally the positioning and visibility
or signal faces and they require
instances the visibility must be
therefore the signal faces this slide
shows the road safety audit of street
lighting at stage 5 you must check and
ensure that through lighting is provided
on at the railroads and highways and
other Belov areas we must ensure that
where the lighting is installed it is of
appropriate standard consistence with
the needs of location pedestrian and
other factors we have to identify
location so a street lighting for poles
constitute
hazard to traffic such as on small
island gnosis of medians and outside of
shaft curves for situations where street
lighting also could be limited by joint
sharing of traffic signal Podesta's and
electric power poles and that the
arrangement of street lights enhances
the guidance rather than conscious
drivers ability to see the direction of
the here for traffic signing we need to
check the general aspects of the
traffic's I assign ages and then for
regulatory and warning sign ages we also
need to ensure the appropriate
regulatory science are provided where
necessary and warning signs have been
used only where they are warranted for
guide and Direction signs we need to
check that light and Direction signs
have been done in a systematic route
original strategy that is not logical
and meets the needs of unfamiliar
drivers so the rest are the requirements
of the guide and directions sign other
items that need to be checked for road
safety audit Stage five is also a
pavement markings and route safety and
leaves landscaping as shown in this
slide so there are there are the various
items which need to be checked and
audited for non safety audit stations
and finally we need also to check the
general traffic management items which
is solely shown in these slides so there
are many items which we require to check
special provisions from for example
special provisions for motorcycle liens
degree of safety afforded to pedestrians
adequacy and credibility of existing
speed deviance effectiveness of this
speed limit sign ages
consider the need for positive advice on
substandard girls and low-speed
cross-sections and Delia nation
requirements for substandard curves and
the placement of several science on day
and the use of red retro-reflective
starts on on locations which are
substandard so these are the general
traffic management items which are
required to be checked in road safety
audit Stage five this last slide shows
the sharp curve at the end of a long
street in a rural rural area which takes
the drivers by surprise and quickly
become accident-prone
the use of advisory speed signs with a
curved warning sign and a good
delineation of the curve is the
preferred treatment so this is some of
the things which we need to consider
during the road safety audit Stage five
