Abstract: Mobility is central to urbanity, and urbanity is central to our common future as the world’s population crowds into urban areas. This is creating a global urban mobility crisis due to the unsustainability of our 20th century transportation systems for an urban world. Fortunately, the science and planning of urban mobility is transforming away from infrastructure as the solution towards a sustainable mobility paradigm that manages rather than encourages travel, diminishes mobility and accessibility inequities, and reduces the harms of mobility to people and environments. In this essay, I discuss the contributions over the past decade of movement analytics to sustainable mobility science and planning. I also highlight two major challenges to sustainable mobility that should be addressed over the next decade.

Lack of access to opportunities contributes to poor social and health outcomes.
Columbus, OH introduced a transit route and schedule redesign and bus rapid transit.
We analyze impacts on accessibility to opportunities in a deprived neighborhood.
Detailed route and schedule data allow high resolution accessibility analysis.
The new bus rapid transit has a much greater impact on accessibility
The absence of effective access to opportunities and services is a key contributor to poor socio-economic and health outcomes in underserved neighborhoods in many cities. The city of Columbus, Ohio, USA is attempting to enhance residents’ accessibility by providing new public transit services. These new services include a major Transit System Redesign (TSR) of the conventional bus network and the introduction of a new bus rapid transit, named CMAX. Using a high-resolution space-time accessibility measure, we analyze whether these new public transit services will change residents’ accessibility to job and healthcare in an underserved neighborhood of Columbus. Also, we assess whether enhancing the CMAX service to reduce delays (e.g., reserved lane, off-board payment system) will improve accessibility. The high-resolution space-time accessibility measure in this study uses published public transit schedules via the General Transit Feed Specification (GTFS). We use multiple departure times during a day to account for the temporal fluctuations of accessibility based on the transit schedule changes. We also consider the operating hours of job opportunities and healthcare services. Results suggest that the TSR yields ambiguous benefits for accessibility to jobs and healthcare. However, the new CMAX service and its potential upgrades lead to a substantial increase in both job and healthcare accessibility. The results can be used for city officials and urban planners to evaluate the effectiveness of public transit innovations in improving accessibility.

U.S. Transportation Secretary Anthony Foxx announced this week that The Ohio State University has been named one of 18 institutions across the country to lead research on transportation challenges outlined in the Department of Transportation’s Beyond Traffic 2045 report.
As a Beyond Traffic Innovation Center, Ohio State is recognized as a forward-thinking and influential institution capable of driving solutions to these challenges by convening decision-makers in the Great Lakes megaregion and coordinating related research, curriculum, outreach and other activities. Due to its location in the center of the country, the Great Lakes megaregion sits at the heart of the U.S. transportation network.
