• Abstract:
  This study was commissioned by INDOT to investigate the cost responsibility and the revenue contribution of highway users with regard to the ; upkeep of Indiana’s state and local highway infrastructure (pavements, bridges, safety assets, and mobility assets). The costs consisted of ; expenditures on construction, preservation, maintenance, and operations of the highway infrastructure. For revenues, user and non‐user sources ; were considered. The highway users were represented by the 13 FHWA vehicle classes, and the study was based on 2009‐2012 data on ; expenditures and revenues. The study framework duly recognized the dichotomy between attributable and common costs. For allocating the ; attributable costs to the vehicle classes, ESALs, AASHTO loading equivalents, and PCEs were used; for allocating common costs, VMT was used. ; For each vehicle class, the share of revenue contribution was compared to the share of cost responsibility to determine respective equity ratios ; and thus to ascertain the extent to which vehicles in each class may be underpaying or overpaying their cost responsibilities at the current time. ; The study also determined the distribution of fuel purchases and travel by out‐of‐state vehicles on Indiana’s highways; this analysis was required ; to further refine the results of the cost allocation and also to quantify the magnitude of any imbalance between the out‐of‐state travel and share ; of consumption on Indiana’s infrastructure and the revenue from such out‐of‐state vehicles. ;         The outcome of this research is a systematic documentation of the sources and extents of highway revenues and the areas of expenditures ; at the local and state levels in Indiana. Pavement and bridge expenditures were found to have a dominant share of the overall expenditures on ; Indiana’s highway system. Classes 2 (automobiles) and 9 (5‐axle combination trucks) were found to have a dominant share of the cost ; responsibilities. It was determined that the user revenue sources contributed approximately 63.5% of the total state funding for highway ; expenditures and 36.5% were from non‐user revenue sources. The inability of user revenue sources to cover the total highway expenditure and ; the consequent partial reliance on non‐user sources seem to constitute a rather unstable funding situation particularly because the non‐user ; sources are characterized by significant variability. On the basis of the expenditures and revenues associated with the various user groups ; (vehicle classes) over the analysis period, this study found that inequities exist, albeit in varying degrees, among the highway user groups. Of the ; 13 vehicle classes, classes 1–4 were found to be overpaying their cost responsibilities while classes 5–13 are underpaying. For example, vehicle ; class 2 is overpaying its cost responsibility by 10% while vehicle class 9 is underpaying by 19%. The results of the equity analysis are generally ; consistent with those of studies carried out at other states. Also, it was estimated that the travel by out‐of‐state vehicles on Indiana’s interstates, ; NHS non‐interstates, non‐NHS and local roads are 21%, 10%, 9%, and 7% respectively, of the total travel as a percentage of VMT on those families ; of highway systems.
