Refined Corridor Assessment
5.0 REFINED CORRIDOR
ASSESSMENT
5.1 INTRODUCTION
Section 5.0 provides a summary of work completed under Task 5 of the PAG HCT Study, which
involved data collection and analysis to determine if one or more premium transit modes in each
HCT corridor are best suited for inclusion into the updated HCT System Plan. Section 5.0
includes the development of several evaluation criteria for comparing modal alternatives in the
HCT corridors and an objective, high‐level summary that helped PAG, the TAC, and the project
team screen out any fatally flawed alternatives or alternatives that are not likely to have a
measurable benefit. Section 5.0 concludes by identifying top‐ranked alternatives for more‐refined
analysis in terms of preferred transit technology, routing, station locations, general service
characteristics, detailed costs, and benefits.
5.2 DESCRIPTION OF CORRIDORS AND
ALTERNATIVES
Figure 48 depicts the corridors and HCT technology alternatives that were identified in Section
4.0 for analysis. Table 18 describes the corridors and alternatives in more detail. These corridors
and alternatives were selected from 16 preliminary corridors in an initial screening of near and
long‐term population and employment densities, low‐income population density, density of
households with zero cars, land uses, location of major trip generators, trip patterns, local transit
service use, and roadway operations.
The HCT modes considered in Task 5 are BRT, LRT, streetcar, and CRT. Express bus may be
implemented in any corridor where ridership and other factors do not justify an HCT mode or as
an interim step in the implementation of an HCT mode.
