  2. Conventional Merge TCP

  3. Basic Approaches • Early Merge • Late Merge

  4. Early Merge • Static • Dynamic

  5. Indiana Lane Merge

  6. Indiana Lane Merge ConventionalMerge

  7. Forced Merges • Indiana: 0.4/hour • Conventional: 20/hour

  8. Capacity • Indiana: 1540 pcph • Conventional: 1460 pcph

  9. Late Merge

  10. Conventional Merge Late Merge

  11. Conventional Merge Late Merge

  12. Conclusions • Early & Late Merge Performed Better Than Conventional Merge • Lower Volumes: Early Merge May Be Safer • Higher Volumes: Late Merge May Be Safer & More Efficient

  13. Dynamic Late Merge

  14. Operational Issue

  15. Research Needed • Volume Thresholds for Transition Between Early & Late Merge • Driver Information Needs • Warrants for Implementation
