  • Abstract:
    The objective of the Stage 3A AMS efforts is to ensure that the Stage 2 models and methodologies can sufficiently replicate and evaluate corridor conditions and the proposed ICM strategies prior to deployment. In Stage 3A, the AMS contractor and the Demonstration site staff confirmed, refined, and validated the parameters and assumptions that serve as the basis for the control strategies currently present in the Stage 2 models. These updated and enhanced models and methodologies can provide further insight on ICM implementation and other operational benefits that will help guide the Stage 3 demonstration projects, future ICM deployments, as well as the post-deployment AMS activities.

    This Pre-Deployment AMS Assessment Report for the I-15 Corridor describes the various tasks associated with the refinement and additional analysis of the Stage 2 models and methodologies in order to support the successful implementation of ICM.

    Chapter 2 provides a brief description of the I-15 Corridor in San Diego, California, and the methodology used for the overall AMS effort. This chapter describes the overall modeling framework used for the analysis and provides detailed information about the assumptions used to model route and mode shift, as well as rules used in modeling the effects of better traveler information be it pre-trip, en-route, or using Dynamic Message Signs.

    Chapter 3 summarizes the AMS work completed as part of the Stage 2 analysis, including analysis scenarios, ICM strategies, modeling assumptions, summary of analysis settings, performance measures, the model calibration effort, and Stage 2 analysis results. Appendix A presents the model calibration results from Stage 2 AMS. Appendix B provides more information on analysis results from Stage 2 AMS.

    Chapter 4 lays out the methodology, model enhancements, model reasonableness assessment, and analysis results for the AMS work completed as part of the Stage 3 pre-deployment analysis. The refined model is capable of adequately representing the pre-deployment corridor operational conditions and corridor management strategies in the I-15 Corridor. Overall, AMS results are intuitive and ICM deployment is expected to produce positive travel time benefits on the I-15 Corridor.
