4. THE IMPORTANCE OFTIA?
When impacts are not accurately projected
through the traffic analysis process, the best
decisions may not be made. Poor decisions
can result in traffic congestion, safety issues,
or unnecessary improvements.

6. WHAT IS TIA?
❑ TIA is an important tool used to determine the transportation
and traffic impact of a proposed site development project
(upon full development) on the surrounding traffic and
transportation systems.
❑ It identifies the need for mitigation measures for a
transportation system to reduce congestion, as well as to
maintain or improve road safety.
❑ Local Authorities will use TIA as basis for assessing and
apportioning a developer’s contribution to road improvements.
❑ Local Authorities also will use TIA to evaluate Traffic
Management Plan proposals.
❑ Provides necessary technical input to other relevant reports
such as Environmental Impact Assessment, Social Impact
Assessment, Development Plan (Structure and Local Plan),
Transport Master Plan and the Road Safety Audits.

7. WHY DO WE NEED TIA?
1. T
o obtain degree of control at access requested by the
private / government entities.
2. T
o determine what type of access required to be
considered and constructed.
3. T
o predetermine future expansion if its required.
4. To offer alternatives solution to traffic improvement as
well as safety measures for the road users.

• Data Collection
Stage 1
• Analysis of Existing Traffic Conditions
Stage 2
• Forecasting of Future Traffic Demand
Stage 3
• Evaluation of Future Traffic Conditions
Stage 4
There are four (4) main stages involved in the TIA process

26. TIA APPROACH
▪ Comprehensive review of literature study, covering all
documents and technical reports pertaining to all
existing and proposed developments surrounding the
development area. (Relevant Local Plan and Structure
Plan, Infrastructure andTransportation Plans, etc.)
▪ Consultations have to be carried out with the local
authority and relevant bodies responsible for any
adjacent development projects to gather necessary
information concerning the overall development
surrounding the proposed project site.
▪ Site visit to determine existing traffic conditions,
existing traffic and pedestrian issues and problems,
and obtaining information on the surrounding road
network, junctions and land uses.
▪ Demarcation of the study area (to consult from the
ApprovingAuthority);
▪ The Classified Count (CC) survey is to be conducted at
peak hours that is determined based on 12 or 16 hours
traffic count.

29. TIA APPROACH
▪ All relevant data collected in Data
Collection Stage is to be used in Stage
2, which is analysis of the existing
traffic data.
▪ Upon data processing, the existing
traffic distribution patterns can be
identified. The relationship of the
traffic pattern and land use
development pattern is also
determined at this stage.
▪ The understanding and establishment
of the existing traffic pattern is vital for
forecasting future traffic demand.
Stage 2 -
Analysis of Existing
Traffic Patterns

30. TIA APPROACH
▪ In forecasting the future traffic growth in an area,
it is a function of demography which involves the
planning variables such as population growth,
employment supply, vehicle ownership,
committed and future property developments
and future road network.
▪ The future trip generation is calculated based on
the above inputs and empirical trip rates which is
established by the Highway Planning Division,
Ministry of Works Malaysia and other relevant
studies. In forecasting the future traffic, it is
necessary to determine the design year for which
the analysis of future traffic is to be undertaken.
▪ Traffic generated from the proposed and adjacent
developments are overlaid on the design year
traffic forecast to produce the total traffic volume
for the Impact AnalysisYear (IAY).
Stage 3 -
Forecasting
of Future
Traffic
Demand

31. ROADTRAFFICVOLUMEMALAYSIA
(TRAFFICGROWTHRATE)

32. TIA APPROACH
▪ Road link and intersection capacities have been
assessed to determine whether the envisaged
road network would be able to accommodate the
traffic demand.
▪ Based on the traffic flow forecasts,
recommendations have been made on the
number and locations of ingress/egress points
required to service the full development and the
form of access intersections required.
▪ Possible locations for access points on to the
existing road network need to be suggested,
taking into account the intersection spacing
standards so as to provide an efficient traffic
circulation.

transport infrastructure.
* Note:
- Project completion period (inclusive of time
taken for Planning Permission Approval to be
obtained and actual construction works) is
assumed to be 2 years & commencement of
project immediately after Planning Permission
Approval obtained in SY. However, if project
completion period is expected to be more
than 2 years, this will have to be determined
and reflected accordingly in the TIA Report.

* Where the Baseline Traffic Condition in IAY is at LOS E, the target mitigated LOS shall also be D.
however, where site condition is very restrictive and the Approving Authority is convinced that the
highest LOS achievable after mitigation measures is level E, the Approving Authority may consider
allowing an exemption of the LOS D requirement.
** BASELINE TRAFFIC CONDITION IN IAY refers to traffic condition without development in IAY.
IAY means Impact Analysis Year.

44. LOS INDICATOR
➢ For each individual intersection, LOS of each lane group of all
approaches shall be presented individually. Overall LOS of an
intersection, though useful as an indicator of the overall
performance of that intersection, is not relevant in TIA study.
Apart from the LOS, the respective degree of saturation (v/c
ratios) as well as the maximum queue lengths and delay shall
also be computed and presented.
➢ LOS provides an indication or measure of the operational
condition of the facility concerned. A range from “A” to “F” is
applicable; LOS “A” represents an excellent level of
operational condition, while LOS “F” an undesirable,
exceedingly congested and failed situation.

45. Road/Mid-block
• Two (2) primary measures used to describe the service quality of a
road or highway.
• These are:
(1) (PTSF) PercentTime-Spent-Following another vehicle, &
(2) (ATS)AverageTravel Speed (km/h).
Intersection
• Defined in terms of delay (kelengahan) as a measure of:
• Driver discomfort
• Driver frustration
• Fuel consumption
• Lost travel time

50. LOS – UNSIGNALIZED INTERSECTION

51. LOS – SIGNALIZED INTERSECTION

52. MITIGATION MEASURES
1. Where the analysis shows that there will be negative impact,
mitigation measures must be proposed to upgrade the
road facilities at that location so as to achieve the
requirements set out in this Guideline. This proposal, as decided
by Approving Authority, with the indicative costs of land
acquisition, design and construction of mitigation measure
which shall be borne by the Developer, shall be included in the
submission for the Planning Permission.
2. In developing mitigation measures, possible improvements in
relation to site access, geometry, traffic signal timing, new
facility, traffic management and other operational issues should
be investigated.
3. When reasonable improvements cannot sufficiently mitigate
the resulting impacts from the development, a review of the
proposed development in terms of project size, land use,
development density or plot ratio should be carried out, with a
view to lessen or reduce the level of such impacts to within the
acceptable level.

53. MITIGATION MEASURES
– Change the intersection layout
o Increase number of lane(s)
o Change the lane sharing (vehicles movement)
o Provide acceleration, deceleration and storage
lane(s)
– Upgrading
o From unsignalized to signalized junction
o From roundabout to signalized roundabout
o From roundabout to signalized junction
o From signalized junction to interchange (grade
