Person delay uses microsimulation to evaluate the delay per person for each mode of travel at an intersection. The person delay for each mode can then be combined to create an overall person delay for the intersection. This method provides a better decision-making tool for developing improvements to facilitate more efficient movement of people, rather than a single mode, through an intersection. It also facilitates the development of multi-modal mitigation measures. It is useful for analyzing higher occupancy travel modes such as BRT or the influence of a grade-separated crossing, as it accounts for benefits or impacts to all facility users.
