• Abstract:
  Local transportation agencies in the Salt Lake City (SLC) Metropolitan Area spent more than a decade ; working toward building a sustainable regional transportation system. Light Rail Transit (LRT) is an ; integral part of that system. Currently, three LRT lines operate along the Wasatch Front area. A new line ; between the SLC International Airport and the University of Utah area currently is under consideration. ; Due to implementation of an additional LRT line, it is anticipated that an expected increase in frequency ; of LRT trains will worsen traffic and transit performance of a large and complex multi modal network. ; The goal of this research is to estimate and analyze the impact of LRT Transit Signal Priority (TSP) on ; other modes of transportation and the performance of a transportation network using microsimulation ; environment. The most prominent feature of the analyzed traffic network is a diverse signal timing ; environment with predictive priority for LRT. Successful integration of VISSIM simulation software and ; Siemens NextPhase virtual controller enabled realistic representation of real-time predictive priority ; settings, which allowed for a comprehensive analysis of traffic and transit performance measures on ; different levels. Results showed the most severe impacts occurred at intersections in the downtown area ; where multiple LRT lines intersected. However, certain areas for improvement were identified. Proposed ; procedures and their effectiveness were demonstrated toward reducing adverse effects of LRT expansion, ; which would validate potential implementation of the proposed strategies in the field.
