文档介绍：Traffic Impact Studies
Introduction
What is a traffic impact study (TIS)?
A study to identify impacts to a work due to a proposed development (or change to an existing development)
monly called traffic impact analysis (TIA).
Who Requires Them?
Governmental agencies (city, county, state) require them to determine necessary mitigation for proposed development as a result of increased traffic demands on work
These agencies will have established thresholds regarding when studies need to be performed, such as:
X number of generated peak hour trips
Site impacts a high-accident location
Specific site access or safety issues are of concern
Why are they necessary?
Why are they necessary?
Satisfy goals of growth management
Transportation infrastructure is provided concurrently with the needs of development generated traffic
Ensures that developers pay their fair share of transportation infrastructure improvements
Who performs TIS’s?
Usually consultants, hired by developers
Professional Engineering (.) licensing usually required
Procedure
Preliminary
Obtain plans/details from developer or architect
Site visit
Determine scope of project
impacted intersection/roadways
need for special analyses
Accident
Parking
Site access
