The Indiana House Enrolled Act 1481 (HEA-1481) requires that the Indiana Department of Transportation (INDOT) adopt final rules by December 31, 2014, for the issuance, fee structure and enforcement of permits for overweight divisible loads, fee structure of permits for loads on extra heavy duty highways, and fee structure of permits for overweight loads. On December 26, 2013, INDOT adopted the Emergency Rules regarding these items, as required by HEA-1481, effective January 1, 2014. HEA-1481 requires INDOT to use the results of this impact study to inform the setting of final rules. Three different fee structures were considered: Pre-HEA-1481 fee structures were in place prior to HEA-1481; Interim Policy fee structures were in place between June 1, 2013 and December 31, 2013; these were superseded by Emergency Rules which took effect January 1, 2014. INDOT commissioned this study to evaluate the impacts of overweight divisible load permits on revenue, asset consumption, alternative transportation modes, Indiana’s economic development, and economic competitiveness relative to other Midwestern states. The results of the analysis indicate that overall, the overweight commodities divisible permit structure arising from HEA-1481 is not expected to change dramatically the consumption of pavement and bridge assets, lead to a slight increase in the revenue collected per permit and a slight decrease in the gap between consumption and revenue. However, the gap between revenue and consumption is still significant. From an operations standpoint, it was estimated that HEA-141 will lead to a net decrease in safety but a net increase in mobility of the traffic stream, due to the twin but opposing effects of traffic impairment and trip substitution associated with overweight vehicle operations. Also, HEA-1481 is expected to lead to little or no shift in the modal share across truck and rail, but significant shift in the specific configurations of vehicles used in trucking operation
