LOS Grade (1=A to 6=F)

2

Effective Width (ft)3
Capacity (ped/min)69
How to Use This Calculator
  1. Enter Sidewalk Width (ft), Peak Pedestrians/Minute, and Obstructions.
  2. Review Flow Rate (ped/min/ft) and LOS Grade (1=A to 6=F).
  3. Use Effective Width (ft) and Capacity (ped/min) to inform your decision.
  4. Use the chart to visualize the results and explore different scenarios by adjusting inputs.

How the result changes with Sidewalk Width (ft)

Sidewalk Width (ft)Flow Rate (ped/min/ft)LOS Grade (1=A to 6=F)
3.901
113.331
201.331
270.911

What each input means

Sidewalk Width (ft)
Total sidewalk width from building face to curb in feet
Peak Pedestrians/Minute
Peak 15-minute pedestrian volume converted to per-minute rate
Obstructions
Number of fixed obstructions (signs, poles, planters) reducing effective width

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    Sidewalk Width (ft) = 8, Peak Pedestrians/Minute = 20, Obstructions = 2 = 3 input(s) provided
  2. Calculate Flow Rate
    Flow Rate
    6.67 = 6.67
  3. Calculate LOS Grade
    2 = 2
  4. Calculate Effective Width
    Effective Width
    3 = 3
  5. Calculate Capacity
    Capacity
    69 = 69
