SE Data,�fi-9 <br /> 11 <br /> 2040 MTP and CTP <br /> Socioeconomic Data <br /> Purpose of Socioeconomic Data <br /> The socioeconomic data (SE Data) shows the location of the population and employment, <br /> median household income and other demographic data that drives the travel demand. <br /> The SE Data is among the most important inputs into the Triangle Regional Model <br /> (TRM)because the residential data is used to determine the number and type of trips and <br /> the employment data is critical for determining the destination for those trips. The <br /> distance between residential and employment centers, and the location of roads and <br /> transit service in relation to those house and jobs, will have a big impact on the travel <br /> distance, travel time, mode shares, and congestion in the TRM output. <br /> Scenarios <br /> The DCHC MPO and the Capital Area MPO partnered together in a process called <br /> Imagine 2040 to create a land use model for the entire Triangle region that is capable of <br /> producing multiple land use scenarios. The GIS (geographic information system) <br /> software called Community Visualization provides the method and data bases for the <br /> scenarios. This partnership created two distinct SE Data scenarios for use in the <br /> Alternatives: <br /> CommPlan— The Community Plan scenario is based on the comprehensive land <br /> use plans of the local jurisdictions and counties. <br /> AIT—The All-in-Transit scenario starts with the comprehensive land use plans <br /> and adds transit oriented development(TOD) around the light rail and commuter <br /> rail stations. The TOD has higher density and more mixed land uses than the <br /> anticipated development in the CommPlan. In addition, the factors in this land <br /> use scenario that drive the attractiveness of the parcels (e.g., land use suitability) <br /> are weighted more positively for rail transit stations. <br /> It is important to note that the county-level population and employment are the same <br /> between the two scenarios. The county-level guide totals established for each county <br /> earlier in the 2040 MTP process are used for both scenarios. The difference between the <br /> two scenarios is the location. The population and employment in the AIT scenario is <br /> more concentrated around the rail transit stations than in the CommPlan scenario. <br />
