Technical Analysis Tools

SDOT staff members employ a variety of quantitative and qualitative technical tools to conduct multimodal traffic analyses. They include:

  • Traffic counts (volumes) that include all modes and vehicle types
  • Crash types, frequencies, and rates by specific locations and along roadway corridors
  • In-depth examination of factors contributing to crashes; and development of counter-measures
  • Pedestrian, motorist, and transit rider surveys
  • Design standards and guidelines (best practices)
  • Ongoing review of current research
  • Traffic (vehicle) forecasting methodologies
  • Operations modeling (e.g. VISSIM)
  • Performance measures and benchmarks for all modes (partially based upon street typologies)
  • Mapping technologies
  • Quantitative and qualitative evaluation criteria for project ranking and prioritization
