Lyndon et al.,
Continuing with Pittsburgh streetcar line traffic data from 1948 (Part 6):

Forbes Avenue (East End) lines

64 - Wilkinsburg - East Pittsburgh
12.7 miles
5,950,000 revenue passsengers

66 - Wilkinsburg via Forbes Avenue
7.6 miles
1,263,000 revenue passsengers

67 - Swissvale - Rankin - Braddock
10.2 miles
5,944,000 revenue passsengers

68 - Homestead - Duquesne - McKeesport
16.0 miles
9,151,000 revenue passsengers

69 - Squirrel Hill
6.2 miles
2,226,000 revenue passsengers

Summary, Forbes Avenue lines
27.7 miles system length (unduplicated).
24,584,000 revenue passengers.
29.9 million "total passengers."

To adjust from "zone passengers" to "revenue passengers," I multiplied
the data presented 
for the longer lines (64, 67 and 68) by 0.9.

Assuming that all five lines carried the same share of "transfer"
passengers as the 
"systemwide" average, I multiplied the data for each line by the 1.33
factor used thus far.

Composite ATD: 4 miles. Determined by assigning average travel
distances as follows:

64 - Wilkinsburg - East Pittsburgh: 4 miles.
66 - Wilkinsburg via Forbes Avenue: 3 miles.
67 - Swissvale - Rankin - Braddock: 4 miles.
68 - Homestead - Duquesne - McKeesport: 4 miles.
69 - Squirrel Hill: 3 miles.

The "weighted average" travel distance is 3.6 miles, which (as before)
is presented in the 
"traffic density tables" as simply "4 mi."
