Lyndon et al.,
Continuing with Pittsburgh streetcar line traffic data from 1948:

Part 4: South Side - South Hills lines ("interurban" division and line
37-Castle Shannon 
excluded.)

42 - Dormont
5.1 miles.
4,338,000 revenue passengers.
["Today's" ridership over this segment is very roughly 3 million
boardings per year.]

--------------------

38 - 38A - Mount Lebanon - Castle Shannon
6.9 miles
4,091,000 revenue passengers.

39 - Brookline
5.0 miles
2,231,000 revenue passengers.

Lines  38, 38A and 39 (sum)
8.4 miles (unduplicated)
6,322,000 revenue passengers.

-------------------

40 - Mount Washington
4.4 miles.
2,375,000 revenue passengers.

44 - Knoxville
3.4 miles.
3,518,000 revenue passengers.

48 - Arlington
3.9 miles
2,059,000 revenue passengers.

49 - Beltzhoover
3.5 miles
1,086,000 revenue passengers.

"Hilltop" lines (sum)
9.4 miles (unduplicated)
9,038,000 revenue passengers.

--------------------

50 - Carson Street
3.4 miles
4,737,000 revenue passengers.

47 - Carrick via Tunnel
6.3 miles
533,000 revenue passengers [I believe this was a peak-only service].

53 - Carrick
6.1 miles
5,892,000 revenue passengers.

Lines 47, 50 and 53 (sum)
9.0 miles (unduplicated)
11,182,000 revenue passengers.

--------------------

South Side - South Hills "urban" lines (excluding 77/54)
24.9 miles (unduplicated)
30,880,000 revenue passengers.

--------------------

77/54 North Side - Carrick via Bloomfield
12.2 miles
8,386,000 revenue passengers.

(I have no information on how to allocate passengers to the "Carrick"
segment, so - 
regrettably - I have not included this line with the other two Carrick
services.

Composite ATD: 2 miles. Determined by assigning average travel
distance per "revenue 
passenger" to the lines as follows:

42 - Dormont: 3.5 miles [this goes onto the table as 2.7 miles,
established during 
previous discussion, because "table" figures include "all" passengers,
"revenue" and 
"transfer"].

38 - 38A - Mount Lebanon - Castle Shannon: 4 miles

39 - Brookline: 3 miles

Lines  38, 38A and 39: summary result (including "all" passengers) is
2.7 miles (2.5 miles 
on the table).

40 - Mount Washington: 3 miles.

44 - Knoxville: 2.5 miles.

48 - Arlington: 2.8 miles.

49 - Beltzhoover: 2.5 miles

"Hilltop" lines: summary result (including "all" passengers) is 2.0
miles (2 miles on the 
table).

50 - Carson Street: 2.5 miles.

47 - Carrick via Tunnel: 4 miles.

53 - Carrick: 2.5 miles.

Lines 47, 50 and 53: summary result (including "all" passengers) is
1.9 miles (2 miles on 
the table).

As before, I calculated a "weighted average" travel distance per
revenue passenger, 
adjusted "downward" to account for revenue and transfer passengers:
2.2 mi for South 
Side - South Hills "urban" lines (excluding 77/54). As before, this
figure is presented on 
the "traffic density tables" as simply "2 mi."
 
(Effects of depopulation can be seen (on Google Maps satellite photos)
in various 
locations, notably in the Beltzhoover district. The Jones & Laughlin
steel mill that once 
provided a major source of traffic for Route 50 is now gone, but part
of the site is being 
redeveloped.)
