Abstract This thesis presents an economic comparison of three different
highway networks which serve an area of 64 miles by 83 miles in size.
Each network is designed to carry the same traffic between any two
towns but is different in total length.
Costs of right of way, excavation, pavement and maintenance
are estimated from unit costs and length of each highway network.
Costs of bridges are estimated by using the unit costs per square foot
of bridge and approximated size and number of bridges. To calculate
road user costs, unit costs per vehicle-mile are obtained from given
references and vehicle-miles are calculated in she following way: The generated trips in each town are estimated from the number of
vehicles and are distributed to other towns by a gravity model. The
number of trips are multiplied by the distances travelled to obtain
vehicle-miles.
Comparisons are made by annual-cost method, present-worth
method, rate-of-return method and benefit-cost ratio method for different
interest rates.
It is found that the network which has the longest highway
length, but is the most convenient, is the most economical one.
