Abstract:Transit preferential treatments (TPTs) are promising strategies for reducing delays for transit vehicles and improving person mobility, leading to more sustainable and economically competitive multimodal transportation systems. However, the exact impact of such strategies, individually or combined, on the person carrying capacity and person delay of signalized arterial corridors are yet to be determined. This project focused on the development of analytical models to explicitly assess the impact of TPTs on the person carrying capacity and person delay of signalized intersections that are part of a larger signalized arterial (i.e., autos arrive in platoons). In addition, domains of application that dedicated bus lanes (DBL) and pre-signals with or without green extension and red truncation, should be used to minimize total person delay for a generic isolated intersection and undersaturated conditions were also determined. These models allow for a comprehensive comparison of various TPTs without the need for time-consuming simulations.
