• Abstract:
  A novel Hardware-in-the-loop Simulation tool was constructed to show how modifications to signal timings would improve coordinated corridor performance. A total of 15 unique microsimulation models were developed and run three times each to test three case studies of bi-direction bandwidth optimization, cycle length sensitivity, and leading pedestrian interval sensitivity. Results show that optimization can improve overall corridor operation, and that all approaches and turning movements must be evaluated. Specific improvements can be targeted using shorter cycle lengths, but cycle length reaches a point where diminishing returns are experienced. Leading Pedestrian Intervals can provide safety improvements for pedestrians, but the effects are influenced by the optimization strategies.
