Abstract: This paper derives the square root bus dispatch optimization developed by Newell from consumer surplus rather than the original cost minimization function. We then extend the model to consider dispatch-variant demand and outline its property relative to the original model by Newell. Demand elasticity is introduced via a multinomial logit mode choice model. Results are tested for City of Edmonton mode choice and ridership. The sensitivity of the function to wait time cost and passenger demand is tested. For the observed passenger demand and value of travel time, our analysis suggests there is a portion of riders who are captive and will suffer increasing wait time costs, but many passengers will make the choice to utilize other modes of travel when faced with increasing bus headways.
