This research presents a series of accessibility methodologies developed for bus-highway system interactions. Accessibility is defined as the collective number of jobs that can be reached by a particular mode of transportation within a given travel time period. The effects of managed lanes (ML), park-and-ride (PNR), and travel costs on walk-up transit accessibility are measured for the Minneapolis-Saint Paul (Twin Cities) region. Each methodology is introduced, supported by a literature review, and described in detail before scenario results are presented. The final analysis uses the ML and PNR methodologies to establish a comprehensive transit accessibility profile for the Twin Cities, which accounts for the dual impact of auxiliary transportation facilities.
