4. Evaluation Methodology RTC SR-160 Corridor Study of Land Management (BLM) land in Enterprise, the window of opportunity to secure land needed for transit is quickly closing. In the following section, current ownership of desirable parcels is described. Methods available for acquiring federally owned right-of-way needed to construct transit-supportive amenities like Park & Ride facilities, transfer stations and intermediate transit stations, shelters and bus stops are also presented. 4.2 SCREENING METHODOLOGY This subsection presents a screening methodology to the corridor alternatives based on formal planning criteria and it establishs a framework for applying this screening methodology to each corridor alternative and recommending an alternative or set of alternatives that best suits the characteristics of the corridor. By design, the methodology to assess the corridor alternatives is taken from the evaluation criteria established for the Las Vegas Valley Long Range Transit Plan, which outlines a strategic vision for long-term transit investments for the Las Vegas Valley. The screening criteria include the following. Mobility Improvements – How well do the proposed transit alternatives improve travel times and options How does the proposed modal solution improve ridership and operational efficiency To what extent will new transit services impact vehicular safety on existing roads where transit routes will be introduced Presence of Transit Supportive Land Use – Is the candidate corridor included in existing land use policies that emphasize smart growth and transit-oriented development Engineering Feasibility – How difficult is the build option to implement What are the estimated capital and operating costs What are the impacts to traffic circulation Supportive Demographics – Are there population and employment densities sufficient to justify the introduction of new transit services Assuming the share of transit-dependent population in the study area is low, how many jobs are within a ½-mile of the corridor Environmental Constraints – How much right-of-way is available to construct facilities required to introduce local, express and bus rapid transit (BRT) services How much relocation of utilities and other assets will be required 4-3
4. Evaluation Methodology RTC SR-160 Corridor Study Community Support – How much community support is there for new mass transit services System ridership is an especially important measure of how effectively new transit service improves both mobility and accessibility. Ridership is related to several factors, including the baseline demographics of the residential population in proximity to transit stations and the transit supportive attributes of land uses within the corridor. In addition, the concentration of major trip attractors along the corridor, such as commercial, retail, tourist, and education, also plays an important role in the potential for new transit service to capture market shares. Generally, sufficiently high residential and commercial densities clustered tightly within a major transportation corridor are required to produce sufficient ridership levels to justify the investment in a fixed guideway mass transit system. This corridor profile is common in major cities with central business districts (CBDs) that represent a significant share of the region’s employment and commercial activity. Where the prevailing transit mode share is high and land acquisition is prohibitively expensive, fixed guideway systems serving urban corridors do not typically require Park & Ride lots as a precondition for attracting ridership. In a lower density environment that may be characterized as suburban, Park & Ride facilities have been adopted as a transit-supportive strategy needed to attract choice riders in areas where the existing automobile mode share is very high. For our purposes, the land use characteristics of the Blue Diamond study area are defined as suburban/rural, with the area between Durango Drive and Decatur Boulevard transitioning from rural to largely suburban.
