Public Transport Planning and Management in Developing Countries

model of a transit line with length L (km), headway h (min), cycle time T (min), and load

factor α

max

(prs/sp). The TU (bus or train) capacity is C

T U

(sps/TU).

Simplifying assumptions for this model are:

a) Total hourly cost of operation of the line C

o

is equal to the product of unit vehicle

operating cost c

o

(Rs/TU-h) and the number of TUs on the line NTU C

o

=c

o

*NTU.

b) Passenger demand (design hour volume p

max

) is constant and is related to the total

number of passengers boarding along the entire line, PL, by a coefficient: p

max

= η

p

PL. ...
