The effect of road roughness on vehicle operating costs for medium-sized trucks: a calibration of existing modelsFinlayson, Adrian Mclean January 1991 (has links)
A project report submitted to the faculty of engineering, University of the Witwatersrand, Johannesburg, in partial fulfillment of the requirements for the degree of Master of Science in Engineering
Johannesburg 1991 / In the economic and social development of any country, an effective road transportation
system is an important factor However, it also consumes a large proportion of the total
infrastructure costs, while the costs borne by the road user for vehicle operation and
depreciation arc even greater. A policy must therefore be adopted in which total
community costs for any road link Of network are minimized. To do this meaningfully,
alternatives must be developed and compared and the trade-offs between them carefully
assessed. This, in turn, requires the ability to quantify the different cost functions for the
desired period of analysis. [No abstract provided. Information taken from introduction] / MT2018

A cost benefit analysis for the bicycle as a transportation alternativeStanislaw, Andrew C. January 1996 (has links)
Cost benefit analysis is the conventional method of evaluating automobile transportation improvements. This study examined traditional automobile evaluation methods and applied the same techniques to bicycle transportation projects. Cost data from recent research is summarized and eleven costs (five internal and six external) were estimated. The cost estimates are used to calculate automobile and bicycle costs per mile of travel. A case study of a hypothetical corridor is used to demonstrate how the transportation costs can be applied to specific planning problems. The case study explores what effect shifts in modal distribution would have on the cost effectiveness of automobile and bicycle alternatives. The findings of the study begin to question the underlying premises of traditional cost benefit analysis in transportation projects. The study suggests that conventional analysis is fundamentally flawed and biased toward automobile transportation. / Department of Urban Planning
