For the MBTA’s Bus Network Redesign, we developed a data-driven approach to designing the high-frequency core of the network. Centering equity, the process algorithmically generated 100,000 possible high frequency bus networks and scored them based on how efficiently they served demand and demand by low-income and minority populations. The results were used in creating MBTA’s newly approved network.

Feng Liu, Mohammad Abbasi (Arizona State University), and Xuesong Zhou (Arizona State University): Integrated analytical and simulation based DTA to address scalability in regional planning applications
This session covers a theoretically sound integrated analytical and simulation-based Dynamic Traffic Assignment (DTA) model to solve dynamic user equilibrium via a gap function, as a nonlinear minimization problem. This integration is especially valuable for large-scale DTA applications (as shown in northern Virginia) since the model is computationally efficient and DTA solution is analytically tractable.

Kaveh Shabani: Truck Classification Schemes Conversions: An Application for SCAG Heavy-Duty Truck Model
For most agencies, regional travel demand models are the primary tool used for forecasting truck travel. These models are calibrated/validated to exogenous data sources, such as classification counts. However, various data sources often use different vehicle classifications/definitions. This study develops cross-classifications that can be utilized to convert between different truck classification schemes.

Ray Saeidi-Razavi, and Peter Furth (Northeastern University): Head Start in Time or in Space?: Determining Needed Leading Pedestrian Interval Length as a Function of Intersection Layout
Leading pedestrian intervals (LPI) are a means of reinforcing pedestrian priority over turning vehicles at signalized intersections, but they incur intersection capacity reduction and increased delay for all users. A model has been developed that suggests intersection layout should be accounted for when deciding on the length of an LPI to reduce its negative impacts.
