Introduction
• Traffic Impact Analysis (TIA) is a traffic engineering
  study which determines the potential traffic impacts
  of a proposed development.

• A TIA usually needs to be submitted by a developer
  before any changes in the land use zoning,
  subdivision maps, site plans or new driveways are
  approved.

• A TIA should start in the earliest planning stages of a
  project including at site selection.

Impact Assessment in the Philippines

  Foundation, Inc. (UPNCTSFI) through Japan
  International Cooperation Agency (JICA)
  development study program

• Objective:
      • To establish a standardized process to serve as
        the basis for the preparation and evaluation of
        traffic impact assessments of urban and
        regional development projects.

Significance of the Study
• This study will evaluate whether the traffic condition
  will be affected by the proposed development.

• This study can serve as an example of a TIA.

• This study will provide knowledge about TIA and its
  contents.
Objectives of the Study
General Objective
  To assess the traffic impact of the proposed
  relocation of Los Baños Municipal Hall

Specific Objectives
• To analyze the existing traffic conditions
• To estimate the future traffic with and without
  development
• To identify the impacts of the proposed development
• To recommend roadway improvements
