Methodologies to Quantify Transit Performance Metrics at the System-Level
Travis Glick
Performance metrics have typically focused at two main scales: a microscopic scale that focuses on specific locations, time-periods, and trips; and, a macroscopic scale that averages metrics over longer times, entire routes, and networks. When applied to entire transit systems, microscopic methodologies often have computational limitations while macroscopic methodologies ascribe artificial uniformity to non-uniform analysis areas. These limitations highlight the need for a middle approach.

Emerging Technologies and Cities: Assessing the Impacts of New Mobility on Cities
Becky Steckler Rebecca Lewis
Digital devices – such as smart phones, tablets, and computers – are significantly changing how people and goods move. Leaders in communities where new mobility services and e-commerce deliveries exist are grappling with how to take advantage of the benefits of these services and mitigate the challenges. Government agencies are just beginning to create strategies and policies to ensure that these new mobility services help communities achieve their goals. These efforts are being led primarily…
