Figure 8 TRIMMS – Step by Step Soft Program Evaluation
The user is guided through a set of questions comprising the six screens. Based on the answers provided, the model automatically applies a set of diversion rates, which were derived using the soft program estimation procedures outlined in the previous section. Just like in the case of hard program evaluation, the user has the option to override the model and manually supply the final mode shares.
Figure 9 shows the layout of the Model Output worksheet. All policies or strategies being evaluated are summarized and their impact is presented and summarized by employing the evaluation metric of choice discussed in the previous section. The layout is similar to that of the EPA Commuter 2.0, to provide continuity to those practitioners already accustomed to pollution emission evaluation. The user can create custom charts by clicking on command buttons located on the worksheet, as well as go back to the “Base Case Scenario.” To better understand how to read and interpret the results, the next section of the report provides application examples.
