Section 4 - Alternatives - Detailed Description • The first two Transportation Systems ( #1 and #2), the 2030 LRTP and Comprehensive Transportation Plan, will be used to compare with the 2035 LRTP Alternatives, and therefore will not form Alternatives. • The next five Transportation Systems ( #3 through #7), are Alternatives for the 2035 LRTP. There is a unique set of Socioeconomic Data (SE Data) for each Land Use Scenario. The Baseline Land Use Scenario, for example, is the SE Data approved by the Transportation Advisory Committee (TAC) for use in developing the 2035 LRTP and is based on the current land use plans and policies of the local jurisdictions in the DCHC MPO's planning area. The other Land Use Scenarios assume certain changes to current land use policies. The Transportation System and Land Use Scenarios have only been combined into logical matches. For example, the Intensive Highway Transportation System assumes many highway improvements, relatively few transit improvements and no fixed - guideway service. Thus, this System was not matched with the Transit Node Land Use Scenario, which is designed to support fixed- guideway stations. There are 15 combinations of Transportation Systems and Land Use Scenarios to for the Alternatives. The System Preservation ( 0) will not require separate travel demand data because the TRM (model) is not designed to be sensitive to the levels of Intelligent Transportation Systems (ITS), Travel Demand Management (TDM) and the other related programs and policies inherent in the System Preservation Alternative. The impact of these particular programs and polices will be accounted for after the model is run (these are sometimes called off -model credits). Description of Transportation Systems Each Transportation System is composed of many highway, transit and other transportation projects. A review of the long list of projects is a difficult task. The table on page 4 provides a summary of the major projects in each of the Transportation Systems to highlight the level and type of investment in the three major modes — highway, bus transit and fixed- guideway. The detailed Highway and Transit project lists are presented at the end of this section. To compute the transportation system performance measures, the Triangle Regional Model (TRM) does not account for transportation facilities and services related to bicycles, pedestrians, Travel Demand Management (TDM), Transportation System Management (TSM), and Intelligent Transportation System (TSM). These facilities and services are accounted for after the model process occurs (called post processing adjustments), and therefore they are not listed in the Transportation System project lists. 4-2
