Essential Terminology for AMS

The following terms are used in describing the AMS effort for the I-210 pilot:

  • Scenario: The operational challenge or problem to be addressed; for example, an incident that affects traffic flow, such as a crash blocking one lane of the freeway for 30 minutes during a weekday afternoon peak period
  • Intervention: The action taken to address the problem, such as changing signal plans or adjusting ramp meters to facilitate the flow of traffic off the freeway, onto arterials, and back onto the freeway downstream of the incident
  • Simulation: A virtual representation that captures both the scenario and the intervention and measures their effects on traffic conditions
