Dwell, the amount of time a bus services a bus stop, is a primary contributor to transit travel times and variability. The Transit Capacity and Quality of Service Manual (TCQSM) capacity analysis incorporates the concept of a failure rate as an estimate of the probability that a proceeding bus will be delayed by a bus still occupying the loading area. Empirical research efforts have not yet quantified the delay that takes place when two or more buses overlap or interact at a bus stop. Utilizing new bus interaction scenarios and variables this research quantifies the impacts of different types of bus stop queuing and interactions in Portland, OR. Novel results of detailed statistical analysis utilizing linear and log-linear regressions are discussed and compared. Results show that the interaction of buses of different routes have a measurable and significant impact on dwell durations. These results may be applied to improve dwell prediction models and to analyze the potential impact of route overlaps on dwell times
