ARIZONA HIGHWAY USER REVENUE FUND
OFFICIAL FORECAST UPDATE
RISK ANALYSIS OF EXPECTED VALUES
as of November 2002
Introduction
This document presents the Arizona Department of Transportation’s (Department) forecast of
expected values for the Arizona Highway User Revenue Fund for the period FY 2003-2012.
Background
The State of Arizona taxes motor fuels and collects a variety of fees relating to the registration and
operation of motor vehicles in the state. These collections include gasoline and use fuel taxes,
motor carrier fees, vehicle license taxes, motor vehicle registration fees, and other miscellaneous
fees. These revenues are deposited in the Arizona Highway User Revenue Fund (HURF) and are
then distributed to the cities, towns and counties of the State and to the State Highway Fund, which
is administered by the Department. These taxes and fees represent the primary source of revenues
available to the state for highway construction, improvements and other related expenses.
Since 1986, the Department has estimated Highway Revenues for the State using a comprehensive
regression-based econometric model. In 1989, the model was updated by Dr. Alberta Charney of
the University of Arizona. The model relied on the estimates of certain “independent variables” to
predict future tax revenues. The model’s revenue forecast was highly dependent on estimates of
the independent variables. Any variability between estimated and actual values could lead to
variances in the tax forecast. In order to deal with this variability, the Department introduced the
Risk Analysis Process (RAP) in 1992. The RAP relies upon probability analysis and the
independent evaluation of the model’s variables by an expert panel of economists. This results in a
series of forecasts with specified probabilities of occurrence, rather than a single or “best guess”
estimate.
In 1997, Hickling Lewis Brod Inc. (HLB), working in conjunction with Dr. Dennis Hoffman of
Arizona State University, developed a new forecasting model to incorporate certain economic data
generated over the past ten years and evaluate the inclusion of independent variables absent from
the 1989 model, to enhance the model’s forecasting accuracy. HLB also eliminated independent
variables that were either not significant to the model or were not readily available.
The new model also took into consideration 1997 legislation (SB 1144 and SB 1398) which
eliminated the weight distance tax on motor carriers, increased weight and use fees for use class
vehicles, and changed the point of taxation on fuel. In September 2000, HLB reviewed the model
and updated the equations. The independent variables contained in the updated model include:
· Arizona real income growth per capita
· Arizona population growth
· Arizona wage & salary employment growth
· Arizona fleet fuel efficiency

Risk Analysis Panel
The Risk Analysis Process relies heavily on the judgments of an expert panel of economists to
provide information critical to the forecasting process. In September 2002, an expert panel of
eleven economists representing public, private, and academic sectors submitted their individual
estimates of the model’s independent variables and comments on the future economic outlook.
The information gathered from the panelists was input into the updated model to produce a series
of forecasts with associated probabilities of occurrence. The panelists’ inputs are reflected in the
attached tables at the back of this report.
Model Results
This year’s RAP panel inputs resulted in a mean forecast of $13,414.0 million for the period FY
2003-2012. The average compound growth rate associated with the forecast was 4.2 percent.
The Department’s Official Forecast totals $13,442.7 million for the period of FY 2003-2012 with
an average compound growth rate of 4.3 percent. The Official Forecast incorporates the 50
percent confidence interval for each year of the forecast. The FY 2003 forecast of $1,107.7
million was developed independently of the econometric model using time-series techniques,
historical and projected growth rates from the model, and recent legislative changes.

Summary
The panel believes that the economy will continue to grow but at a slower pace. They forecasted
lower growth rates for Arizona real income per capita and Arizona wage and salary employment
during FY 2003-2012. However, they believe the Arizona population growth rate will remain
about the same. For FY 2003-2012, there was a $145.4 million decrease in HURF revenue
forecast, which was due mainly to the panel’s more conservative view of Arizona’s long term
economic outlook.
