level of transportation in the philippines

2. Introducton
to
TIA
According to a 2014 report by
the Japan International
Cooperation Agency (JICA),
traffic demand for Metro Manila
alone stands at 12.8 million
vehicle trips, exceeding the
capacity of most urban roads.
Therefore, assessing a proposed
development’s traffic-related impacts is
imperative before any permanent
construction begins. Development
projects in the Philippines that may result
in a considerable increase in vehicular
and pedestrian traffic need a thorough
Traffic Impact Assessment report
(TIA).
TRAFFIC CAUSES:
 Population Growth
 High Vehicle Density
 High-density Urban
Development
Continuous expansion of urban
areas due to development and
construction of establishments
including malls, schools, and
commercial buildings.
High Density Urban
Development

3. Traffic impact assessment (TIA) is a powerful
tool for engineers and planners to determine the
possible effects of a project on the transportation and
traffic system.
It is a useful tool for local governments,
especially for managing traffic and in planning their
respective transportation systems.
What is
Transportation
Impact
Assessment?

4. A Traffic Impact Assessment enables the
road authorities to determine whether an existing
road network can handle the traffic generated by
the proposed development, particularly in the
short term.
It includes formulation of traffic
management schemes and recommendation of
infrastructure for possible transportation and
traffic problems that will be encountered during
the construction and operation phases of projects.

5. The city planning office may subject any vertical
development, whether residential, commercial,
office, industrial, or mixed-use, to a TIA report if it
falls under the three factors identified by the UP
National Center for Transportation Studies, Inc.
These are the following:
1. Transportation Impacts
2. Traffic Generation – threshold may be taken
as 100 or more vehicles trip during the
morning and afternoon peak hours
succeeding the project’s operation.
3. Parking Generation – the threshold is a
parking deficiency of one or more parking
spaces generated by the project when it
might impact an already congested or high-
accident location or when specific site access
and safety issues are of concern.
When is a TIA
required?

6. Without a comprehensive understanding of the
volume, time, and location of its traffic
movements, there is a risk of safety problems
and unanticipated congestion on projects
immediately connected to roadways in its
neighborhood.
Consequently, the need to identify and prepare
countermeasures for the traffic impacts of
urban expansion via Traffic Impact
Assessment is a momentous step

15. EXAMINATION OF
TWO CASES

16. LOCATION OF THE TWO CASES EXAMINED
Case 1 – 670 Heights Condomenium
• Complied with the
requirement of the
EIARC to conduct TIA.
Case 2 – Skycity
• Failed to conduct traffic
impact studies despite strong
recommendations from the
EIARC

17. Case 1
Case 1 – 670 Heights Condomenium
• 40-storey mixed-use building
• Located along EDSA in the Cubao
central business district of Metro Manila.
• Traffic management schemes for this
project were developed in part upon
close discussion with the EIARC and the
MMDA

18. 1. Estimation of future traffic generation with and without
the project;
2. Estimation of traffic volumes at approach routes and
critical intersections with and without the project;
3. Identification of locations of potential traffic congestion
due to the project; and
4. Recommendation of remedial measures to overcome
potential traffic problems with the project.
The assessment conducted for 670 Heights
included the following items:

19. 1. Inventory of the physical conditions of the study area;
2. Conduct of primary and secondary traffic count data
for roads in the projects environs;
3. Projection of traffic generated/attracted by the
development;
4. Estimation of levels of service of roads and
intersections; and e. Evaluation of impacts of future
traffic.
Tasks undertaken to meet the requirement of
MMDA and EIARC

20. Case 2
Case 2 – Skycity
• Proposed 85-level building project.
• Envisioned to be the tallest building in the
Philippines.
• Its proximity to major traffic generators like the
SM Megamall and Robinsons’ Galleria combined
with the facilities that will be located in building
underline the importance of conducting TIA.

21. The developers opted to conduct a
simplistic study that understated the
negative impacts of the project and
passed the burden of countermeasures to
the local government and the
Metropolitan Manila Development
Authority (MMDA).

22. COMPARISON
OF
TWO
CASES
• Recognized the
importance of
conducting a TIA.
• 670 Heights was
granted and ECC.
• Good Example that
other developers
should emulate
• Disregarded the
valid concerns of
stakeholders.
• Skycity’s
application was
disapproved.
• Developers should
avoid same
application.

SUSTAINABLE TRAFFIC
MANAGEMENT

24. Development of Traffic Management Plan
1. Those that pertain to the preparation of traffic
management measures both for the construction
and operation phases of the development;
The first relates to the creation of project-specific
traffic management plans. In order to estimate future
situations, baseline data are established, and the
current traffic situation is evaluated. These scenarios
include construction-related traffic as well as
operational stages. (For instance, in regard to a
residential condominium's occupancy). Future traffic
volumes are predicted using historical data, and
growth rates depend on the approach used.
Although there are many difficulties and concerns that are regularly
expressed throughout the development of a TIA, they may be
categorized into the following groups:

25. Development of Traffic Management Plan
2. Those that pertain to traffic congestion due to the
development
The second focuses on opinions on the development's
potential impact on traffic flow. This is a prevalent
worry, and it usually includes parking, traffic, air
pollution, and noise problems.

26. Those that pertain to traffic congestion due to the development
Development of Traffic Management Plan
The third concentrates on developing suitable solutions to the stated
problems, including determining who is in responsible of putting the
required preventative measures into place (such as infrastructure that
must be constructed to reduce congestion or to enhance safety). These
serve as the starting point for developing a traffic control strategy.

3. Those that pertain to the provision of recommended countermeasures or solutions to
transportation and traffic problems brought about by the development

27. PUBLIC INVOLVEMENT & THE RESPONSIBILITY OF
THE GOVERNMENT
Government should take a proactive role by being
informed of changes, understanding their effects, being
sensitive and critical during the decision-making process,
and being watchful while a project is being implemented.
Regardless of their opinions towards a particular
development, it is also the responsibility of the
government to ensure that all sectors are represented.
Government should play a significant role in engaging them within the neighborhood or
community where the project will be located.

28. It is advised that organizations
like the MMDA participate in
the EIARC's evaluation process
to get active in mandating TIA.
These organizations must also
make a commitment to
creating, authorizing, and
putting into effect rules that
mandate TIAs be conducted for
a variety of projects that are
thought to have major traffic
implications.

29. 1. Quality of baseline data
2. Accuracy of traffic forecasts
3. Soundness of traffic analysis employed
4. Suitability of recommended countermeasure
To be effective in anticipating and solving prospective transportation and traffic issues, a TIA
must be thorough and trustworthy. Completeness in terms of material would suggest a
thorough method of assessing affects. Meanwhile, dependability will be demonstrated by:

30. CONCLUSION AND RECOMMENDATION
The effects of advancements on the traffic
and transportation system are frequently
ignored.
Developments' effects on the
transportation and traffic infrastructure are
frequently disregarded.

31. The findings of meticulous and systematic
examination of "with" and "without" development
scenario analysis will be used to identify
countermeasures to probable problems.
A clear and thorough grasp of the circumstances
pertaining to the effects on the transportation and
traffic system can be gained through such an
approach.
Only when specific project plans are developed in
relation to other proposed projects and integrated
with the government's schemes can sustainability in
transportation planning, including the establishment
of realistic and effective traffic control schemes, be
accomplished.
CONCLUSION AND RECOMMENDATION

32. People who make up the stakeholders in the TIA
or EIA process are assumed to be the same
people who the government would act in the
interests of.
As a result, the government ought to actively
promote TIA, if only to make sure that
stakeholders and developers are aware of the
advantages of TIA and the drawbacks of not
doing impact analysis.
