Computing New Dimensions for Use in Multimodal Access Metrics


1:40pm - 3:00pm


1605 Tilia, Room 1103, West Village


Building on decades of academic research, multiple city and state DOTs and MPOs have adopted multimodal access measures, such as the number of jobs and other opportunities reachable in a 45-minute door-to-door commute. Cloud-based software platforms have resolved past technical barriers, enabling use of such measures in project selection, operations analysis, and equity assessment. This presentation highlights recent applications and advances of one such platform to incorporate new dimensions of access in addition to travel time, such as comfort and safety for cyclists, schedule variability and reliability for transit riders, and fare costs and monetary constraints.
