2F. Nonmotorized facilities analysis

Question 1

What is the maximum capacity of effective walkway width?

Answer 1

23 p/min/ft

Question 2

Where can fixed object effective widths be found for calculating Effective walkway widths?

Answer 2

HCM 24-9

Question 3

How to calculate pedestrian flow rate
(Step 2 in calculating LOS for pedestrian walkways)

Answer 3

Similar to Peak Hour Factor
Vp = V15 / (15 x We)

Vp = pedestrain unity flow rate (p/min/ft)
V15 = Pedestrain flow rate during peak 15 min (p/hr)
We = Effective walkway width (ft)

Question 4

How to calculate Calculate Average Pedestrian Space
(Step 3 in calculating LOS for pedestrian walkways)

Answer 4

Ap = Sp / Vp

Ap = Pedestrian space (ft^2/p)
Sp = Pedestrian speed (ft/min - HCM 19-81)
Vp = Pedestrian flow per unit width (ped/ft/min - step 2)

note - Often the question will give you ft/s and Sp is in ft/ min

Question 5

How to Determine Effective Walkway Width (We)?
(Step 1 in calculating LOS for pedestrian walkways)

Answer 5

We = Wt - Wo

We = Effective walkway width (ft)
Wt = Total Walkway width (ft)
Wo = Sum of fixed-object effective width (HCM exhibit 24-9)

Question 6

Where can the LOS table be found for pedestrian walkways

Answer 6

HCM Exhibit 24-1
