Bus Stops near Signalized Intersections: Analytical Models, Management Strategies and Design Guidelines

Curbside bus stops are often located in close proximity to signalized intersections. A bus that dwells at a stop of this kind can impede queued cars upstream as they attempt to discharge into the intersection during green times. This state of affairs adds to the delay and queueing of cars, which in turn can negatively impact the bus. The project seeks to formulate analytical models that quantify these negative impacts of bus-stop operation. The models will be developed using kinematic wave theory, and the project envisions very general models that can be applied: to bus stops that are located either upstream or downstream of their neighboring intersections; and to wide ranges of car and bus demand and roadway geometry. The project will use the models to theoretically explore innovative bus-stop management strategies. The goal here is to devise strategies that improve travel for both buses and cars. Model predictions will be tested against simulation and real observation. Finished products will include a set of guidelines to assist practitioners in determining both, where to place bus stops relative to intersections, and how to manage the buses and cars at and around these stops in greener ways.
