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.
