Presentation Transcript

  1. Overview • Detailed description of Cost Matrices • Commuter • Transportation • Accessibility • Steps to building a simulation and understanding your results

  2. Commuter Cost Matrix • Captures changes to time per trip for off-the-clock, work-related trips. • Calculated through VHT/Trips • Think—Would NYC still be a financial center without its subway system?

  3. Transportation Cost Matrix • Captures the on-the-clock business travel and transport of goods. • Calculated in two ways: • Ratio of VMT to VHT between alternate and baseline scenarios • Cost per trip of commercial truck deliveries

  4. Accessibility Cost Matrix • Calculates changes in access to intermediate inputs and consumer goods • Explains residual bias toward local suppliers • Calculated through Trips/VHT

  5. Accessibility Cost Matrix Baseline value calculated with REMI dynamic estimation to estimate distance deterrence factors which are normalized to 1.

  6. Capturing Mobility Benefits of Long-Range Plans (1) • Step 1-Importing Travel Files • “maintenance only” base case • “maintenance + capacity improvement” alternate case

  7. Capturing Mobility Benefits of Long-Range Plans (2) • Step 2-Identifying Adjustments to Simulation Options • Emissions • Safety • Operating Costs • Value of Time • Cost Matrices

  8. Capturing Mobility Benefits of Long-Range Plans (3) • Step 3- Understanding the Results • Analytical graphs • Labor productivity? • Sector sensitivity to transportation? • Industrial composition? • Cross-regional benefits?

  9. Capturing Mobility Benefits of Long-Range Plans (3)

  10. Coming Up Next Time • Session 3: Client Application • Step-by-step walkthrough of two road projects • comparing benefits and costs
