Transportation Impact Analysis (TIA)

A Transportation Impact Analysis (TIA) assesses whether a development will adversely affect surrounding infrastructure and identifies strategies to mitigate those impacts. This course aims to introduce students to the fundamental concepts of traffic engineering and its connection to environmental impact. Students will learn to estimate the congestion and safety effects of a specific development on the surrounding transportation infrastructure. 

Student Learning Outcomes (SLO)   

Upon successful course completion, students will be able to:   

  • Articulate the need for a Traffic Impact Analysis.
  • Develop a basic understanding of the knowledge and concepts related to traffic data collection.
  • Identify problems and their causes in traffic data collection programs.
  • Analyze data collection and processing tools and techniques for historical trends and forecasting.
  • Recognize the duties of a Traffic Data Technician within the region’s traffic counting program.
  • Understand the overall framework of Traffic Impact Analysis.
  • Conduct step-by-step operational and safety analyses.
