... 11 chapter two Review of LiteRatuRe and PRactice This chapter summarizes the literature review and review of typical agency practices, the findings of those reviews, and their relevance to the overall study. Because of the nature of the topic, resource allocation is addressed in the literature primarily through conference and peer review proceedings, state-of-the-practice reviews, and other documentation of transportation agency experiences.

... 12 of executive leadership and the transportation commission in adjusting program levels while still recognizing the goals documented in the LRTP. Other states' contributions at the peer exchange are discussed throughout this chapter.

... 13 STIP. One presentation discussed how the increasing degree of financial planning occurring within the STIP process limits the influence of the LRTP and strategic goals in setting program funding.
From page 14...
... 14 focus of performance measure discussions and cross-modal allocation methodologies, as seen in the following sections. These include a discussion of the tools used for allocating resources by building up from projects or comparing overall programs.

... 15 ex post evaluations. Some studies, including one conducted by the Appalachian Regional Commission, have looked at selected programs in an ex post evaluation, yet have been challenged by difficulties in obtaining retrospective performance and asset condition data sufficient to isolate programmatic investment levels in direct relation to system conditions and performance (Wilbur Smith Associates 1998)

... 16 programs difficult to assess. Consequently, progress toward performance goals is largely an issue of optimization within programs rather than more optimal reallocation to achieve goals across programs.

... 18 state DOTs utilize these types of models regularly in developing needs-based program allocations based on performance targets. travel demand models Although travel demand models are not investment management tools per se, they play an increasingly important role in how agencies understand likely future demands and consequently investment requirements.

... 21 France makes use of its relatively new LRTP Schéma National des Infrastructures de Transport, which follows the principles of sustainable development (French Ministry of the Environment, Energy and the Sea 2011)
From page 22...
... 22 Multicriteria processes often have been helpful for agencies in reconciling projects of different programs in a single TIP or STIP process by applying normative weights to reconcile the quantifiable project benefits to the subjective values of policy objectives. However, such processes have not been well documented as a basis for overall programmatic allocations at higher than the project level.
