Travis Glick received his Ph.D. in civil and environmental engineering from Portland State University. His doctoral work tackles a new class of problem that accounts for multiple routes and multiple service connections. It combines stochastic modeling techniques with new, high-resolution data sources and route-level methodologies to model and analyze performance measures for an entire transit network. Previous network-level analyses rely heavily on deterministic network models that assume linearly dependent costs and travel times; however, there is significant non-linearity in how travel-times and transit costs are valued by users and agencies in real networks.
