Empirical Evidence on Traffic Induced by Paving Roads in Chile
Induced traffic could be an important consideration for the economic cost-benefit analysis of road paving projects. However, road paving projects generally do not justify the data collection required to estimate the induced traffic. International evidence is very scarce and consists of elasticities that should be applied to the change in origin-destination generalized costs produced by the road paving; unfortunately these data are generally not available. This study offers empirical evidence on the traffic induced by road paving projects, considering 91 projects in Chile and biannual traffic count data for the period 1994 – 2010 from the Ministry of Public Works’ National Census Plan. Elasticities for induced traffic have been estimated with respect to the changes to the generalized cost of trips over the paved road section, for light vehicles and buses. Overall the rate of induction of traffic as a result of road paving was estimated at approximately 10% for passenger vehicles. In the case of heavy vehicles the rate of induced traffic was insignificantly different from zero with a best estimate of approximately 3%. The results of this study will inform the guidelines for economic evaluation of road paving projects in the context of the National Investment System of the Ministry of Social Development of the Government of Chile. These results help to fill a gap in the international evidence and provide elasticity estimates for induced traffic due to road paving projects that are readily applicable with available data.
