Analysis methodology for estimated cost of inadequate riding quality in South Africa

Abstract

Paper presented at the 32nd Annual Southern African Transport Conference 8-11 July 2013 "Transport and Sustainable Infrastructure", CSIR International Convention Centre, Pretoria, South Africa.

Deteriorating road conditions can potentially have negative effects on road user costs. This is mainly due to the increased vibrations experienced by vehicles travelling on poor roads resulting in additional structural damages. The negative effects of deteriorating road conditions extend far beyond their impact on businesses, with deteriorating road conditions ultimately having a negative impact on the economy and competitiveness of a country. This paper discusses a method developed for the analysis of the national impact of inadequate riding quality on major freight corridors, and demonstrates the need to ensure that these corridors are maintained in a good condition.
