[email protected]. Analyses of Bus Travel Time Reliability and Transit Signal Priority at the Stop-To-Stop Segment Level by Wei Feng A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Civil and Environmental Engineering Dissertation Committee: Miguel Figliozzi, Chair 1 Robert Bertini Christopher Monsere James Strathman Portland State University 2014 1 © 2014 Wei Feng 2 2 i ABSTRACT Transit travel time is affected by many factors including traffic signals and traffic condition. Transit agencies have implemented strategies such as transit signal priority (TSP) to reduce transit travel time and improve service reliability. However, due to the lack of empirical data, the joint impact of these factors and improvement strategies on bus travel time has not been studied at the stop-to-stop segment level.
