However, even given these efforts to disseminate information on the various tools, there has been wide variation in States' level of interest in the tools. As displayed in Table 2.2, flexible match and certain cash flow tools have proven most popular under TE-045. Table 2.2 illustrates each instance in which each of the eight financing concepts has been employed on an active TE-045 project. FHWA quarterly TE-045 project updates and supplementary independent telephone interviews. As previously noted, phased funding is no longer being tested.
Tapered match continues to be tested, but only on an experimental basis.
The number of projects displayed in Table 2.2 sums to more than 71 because two or more financing tools were used in combination on 12 projects. A number of factors contributes to States' varying degrees of interest in the individual financing techniques that comprise TE-045's financial toolbox. One important influence on the use of a particular tool is the extent of its applicability to a wide range of situations. Some tools hold nearly universal appeal, while other tools instead offer targeted remedies to unique funding dilemmas. Some of the less commonly used tools, such as Section 1044 toll investment credits, have a narrower scope of applicability, and therefore a lower incidence of use.
