This book brings together reports of original empirical studies which explore the impacts of the COVID-19 pandemic on urban mobility and transportation and the associated policy responses. Focusing on the California region, the book draws on this local experience to formulate general lessons for other regions and metropolitan areas.  The book examines how the COVID-19 pandemic has had different impacts on vulnerable populations in cities. It explores the pandemic's impacts on the transportation industry, in particular public transit, but also on other industries and economic interests that rely on transportation, such as freight trucking, retail and food industries, and the gig-economy. It investigates the effect of the viral outbreak on automobile traffic and associated air quality and traffic safety, as well as on alternative forms of work, shopping, and travel which have developed to accommodate the conditions it has forced on society.With quantitative data supported with illustrations and graphs, transportation professionals, policymakers and students can use this book to learn about policies and strategies that may instigate positive change in urban transport in the post-pandemic period. 

"Every major American city has a highway tearing through its center. Seventy years ago, planners sold these highways as progress, essential to our future prosperity. The automobile promised freedom, and highways were going to take us there. Instead, they divided cities, displaced people from their homes, chained us to our cars, and locked us into a high-emissions future. And the more highways we built, the worse traffic got. Nowhere is this more visible than in Texas. In Houston, Dallas, and Austin, residents and activists are fighting against massive, multi-billion-dollar highway expansions that will claim thousands of homes and businesses, entrenching segregation and sprawl. In City Limits, journalist Megan Kimble weaves together the origins of urban highways with the stories of ordinary people impacted by our failed transportation system. In Austin, hundreds of families will lose childcare if a preschool is demolished to make way for Interstate 35. In Houston, a young Black woman will lose her brand-new home for a new lane on Interstate 10-just blocks away from where a seventy-four-year-old nurse lost her home in the 1960s when that same highway was built. And in Dallas, an urban planner has improbably found himself at the center of a national conversation about highway removal. What if, instead of building our aging roads wider and higher, we removed those highways altogether? It's been done before, first in San Francisco, and more recently, in Rochester, where Kimble traces how highway removal has brought new life to a divided city. With propulsive storytelling and ground-level reporting, City Limits exposes the enormous social and environmental costs wrought by our allegiance to a life of increasing speed and dispersion, and brings to light the people who are fighting for a more sustainable, connected future"--
