Show CMAP Modeling Results: "Preserve" Scenario June 8, 2009 1 Results of "preserve" scenario travel modeling Introduction and purpose The GO TO 2040 plan, due to be complete in 2010, will make recommendations for policies, strategies, and investments in transportation and other fields. This document is part of a series that begins to examine potential plan recommendations by testing the effectiveness of "sample programs" of systematic improvements of different types. In this case, a sample program for transportation management and operations was developed that is consistent with the theme of the preserve scenario and a "Complete Streets" planning approach. It assumes that the region invests heavily in our current transportation assets and that forecast growth and development can be accommodated by devoting transportation funds primarily to improving the performance of existing facilities. Each of the alternative regional planning scenarios uses a different balance of capital and non-capital investment, and this scenario minimizes investment in new transportation capital facilities. Before reviewing the remainder of this document, please read the following notes, which explain its purpose and limitations: Implementation: This document does not address the responsibility for implementing the sample programs described here. This is very important consideration and will be addressed as a next step. Scenario context: In reality, transportation management and operations will not be pursued in the absence of other strategies. CMAP recognizes that the benefits of the strategy are magnified when linked with compatible land use measures. As a later step, transportation management and operations will be analyzed along with other strategies; but for this series of documents, CMAP is attempting to isolate and examine the benefits of the transportation components of each scenario. Specificity: The results of the analysis are not accurate at the individual facility level and further geographic detail beyond what is shown in this document cannot be given. Assumptions: To perform the analysis of the sample program described here, assumptions were made for appropriate locations for improvements and their effects. The purpose of the document is to allow these assumptions to be discussed and questioned. The purpose of the analysis and modeling exercise is to determine, on a regional scale, where and to what degree transportation management and operations strategies should be applied, how much such a program would cost, and how it will impact key indicators. Key assumptions Any regional analysis and modeling process involves making assumptions. The fundamental assumptions for the transportation management operations strategies associated with the preserve scenario involve the following: The definition of transportation management and operations strategies |
