  7. Methodology Bus Stop Capacity Main Inputs Calculation Worksheet Output # of Loading Areas Dwell Time Bus Stop Capacity [bus/hr] Signal Timing Clearance Time Right-Turn Traffic Failure Rate

  8. Methodology Corridor Capacity Main Inputs Calculation Worksheet Output Adjacent Lane traffic Corridor Capacity [buses/hr] Blue Zone Capacity Yellow Zone Capacity

  9. Methodology Capacity Analysis Results SOUTHBOUND NORTHBOUND Pine St Critical Bus Stops Capacity Capacity Pike St Yellow Stops 80 buses/hr NB Corridor Capacity: 130 buses/hr Union St University St Seneca St Blue Stops 65 buses/hr Spring St Blue Stops 65 buses/hr Madison St Marion St SB Corridor Capacity: 130 buses/hr Yellow Stops 85 buses/hr Columbia St Cherry St James St

  10. Scenarios First Attempts Pine St R R • Bus Stops Overloaded • Blue SB • Yellow NB • Possible Solutions • Move routes to 2nd/4th Ave • Split common routes • Different color per direction • Something else?
