47 As acknowledged previously, the steps in this guidebook are not always followed consecutively, and there is ample room for reflection and returning to earlier steps in an iterative way. This may be particularly true for Step 6, as the process of refining a treatment plan may require revisiting the actions, assumptions, and decisions made in prior steps.

50 Systemic Pedestrian Safety Analysis Table 18 offers a hypothetical example for how to apply a cost-effectiveness index to a selection of 26 potential treatment sites identified in Step 4, using model-derived SPFs and established CMF and countermeasure cost data. Site 1 represents the site with the highest predicted crash risk based on the SPF model, as indicated by the relatively high number of predicted crashes (A)

52 Systemic Pedestrian Safety Analysis Allocate Funding State and local agencies may need to change or adapt existing policies to allocate funds to systemic safety projects. For some states, this may require an adjustment in how projects are prioritized (see section on considering additional community priorities)
