The AMS Phase 1 study enabled the project team to gain an initial understanding of the processes, needs, and capabilities involved in modeling the I-210 corridor. This led, in AMS Phase 2, to implementation of the Aimsun microsimulation model, a robust and detailed commercial model to which the team added extensive information about the I-210 corridor, including:
- 1000 lane miles of road
- 5000 traffic detectors
- 459 signalized intersections and control plans
- 45 freeway ramp meters
- Metro Gold Line light-rail and all bus routes
The model also takes a range of other data into account: school zones/bell schedules, conflicting flows at intersections, U-turn areas, driver behavior (e.g., stopping in the middle of an intersection), and more.
As the project timeline shows, AMS Phase 2 extends until the start of system operations. Model development, calibration, and refinement thus proceed for much of the project, in parallel with other tasks. In October 2016, the project team presented a comprehensive review of the AMS effort, showing the progress and direction of development at that point.
