Abstract/Description: Moveable bridges create critical intersections on roadways causing excessive delays to vehicles and vessels. Vehicles are forced to form a queue when the vessel traffic is being serviced and similarly for vessel traffic. Stochastic and deterministic queuing models such as Adolf May Continuum model and Webster methodology, etc… are explored to determine the queue characteristics, including CORSIM simulation software to model the vehicular queues at the moveable bridge location and the adjacent roadway intersections. Vehicles delayed by the moveable bridge opening incur high user delay costs. Objectives of this study include evaluating delay at moveable bridges and adjacent intersections, as well as evaluating level of service ratings and estimating associated costs, especially user delay costs, with replacement options. Replacement considerations to potentially reduce the delay and user costs would include the following options: (1) Existing moveable bridge, (2) higher moveable bridge, and (3) higher fixed-span bridge. To determine the feasibility of replacement alternatives a replacement cost model was developed. The replacement cost model incorporates life-cycle cost analysis with results, showing that the replacement options reduce or eliminate the delay conditions with an emphasis on reducing user delay costs. Results obtained from the continuum queue model and CORSIM software were compared with the field observations and it was concluded, using statistical tests, that the continuum queue model and CORSIM simulation software could accurately predict the queue characteristics.
