Section 2 - Alternatives - Model Data - Performance Measures 2035 LRTP and CTP Alternatives — Performance Measures Purpose of Performance Measures Performance Measures provide a general indicator of the a transportation system from a variety of perspectives such as mobility, travel time, congestion, mode choice, air quality, financial, and environmental justice (i.e., perspective of minority and low- income populations). The measures are not specific to a particular travel corridor but instead cover the entire transportation system, and therefore are useful for comparing the efficiency and effectiveness of the different transportation Alternatives. Most of the data used for calculating the Performance Measures comes from the Triangle Regional Model, which is a travel demand model that forecasts future travel statistics based on a set of assumptions concerning the highway network, transit service and other transportation facilities. The tables in this section provide the Performance Measures for the fifteen different transportation Alternatives that are being analyzed. Each Alternative is a combination of one of the five transportationsystems , including: • Comprehensive Transportation Plan; • Intensive Highway; • Intensive Fixed Guideway; • Intensive Bus Transit; and, • Moderate Multimodal, And, one of the five Land Use Scenarios, including: • Baseline; • Constrained; • Buildout; • Travel Corridors; and, • Transit Node. (Note: For additional information on the development of the Alternatives, see Section 4, "Alternatives — Detailed Description" in this report.) Performance Measures Tables For comparison purposes, the Performance Measure tables are organized by transportation system type, plus the first table compares all the Alternatives that use the Baseline Land Use Scenario. The order of the tables on the following pages is: 2 -1
