Automobile use has been on the rise in cities for nearly a century and so has the supply of parking. Because driving often seems unavoidable, policymakers, developers and the public push endlessly for more parking to meet demand. That push, however, might only be making matters worse. SSTI Senior Associate Chris McCahill’s research suggests that abundant parking in cities causes people to drive more, shedding important light on the question of cause and effect.
Where and how communities grow and build homes, transportation, and other infrastructure is likely not at the forefront of most disaster preparedness agencies’ agenda. Yet a community’s decisions about land use and transportation have significant impacts on how resilient it can be in the face of disasters. This document is intended to introduce and integrate land use and transportation issues into states’ conversations about resilience. Disaster preparedness professionals can use it to understand how strategic decisions about land use and transportation can build communities that are more resilient from the ground up.
Transit often fails to get the credit it deserves for reducing traffic and emissions. In most U.S. cities, transit’s mode share is in the single digits, so the direct effect of ridership seems small. And while it’s clear that even in places with low mode share transit plays a role in raising densities—and thereby reducing travel distances—this relationship has been hard to quantify; conventional demand models simply take land use as an input. Filling this gap is a report and tool from TRB’s Transit Cooperative Research Program.
In the past decade, several cities have transformed their streets by adding bus and bike lanes, creating new pedestrian plazas, and emphasizing the movement of people instead of cars. This new report examines six cities’ recent innovations in urban transportation. It looks at what is behind successful change and found common elements. Based on the experience of the cities studied, TransitCenter recommends actions for transit advocates, policymakers, foundations, and anyone interested in transportation change.
Deloitte’s Public Sector Research organization offers a study that found that the expansion of alternative modes of transportation could lead to reduced congestion and other benefits, and identified the types of transportation suited to a city or suburb. The study uses geospatial analytics, such as coupling location data with existing government data, to examine the potential congestion reduction benefits in major metropolitan areas across the U.S. Congestion reduction could result from the expansion of alternative modes of commuting.
This research review highlights findings from studies conducted in several states and cities that have examined walking or biking rates, safety, and economic issues associated with Safe Routes to School.
This new report identifies specific modifications to the Vermont State Standards, recommends changes to other related VTrans guidelines and policies, and presents an implementation plan and schedule for conducting the revisions. The Vermont State Standards provide VTrans staff and other partners with direction in designing roadway transportation projects.
Urban sprawl costs the American economy more than $1 trillion annually. These costs include greater spending on infrastructure, public service delivery and transportation. This report details planning and market distortions that foster sprawl, and smart growth policies that can help correct these distortions.
After declining every year since 2004, vehicle-miles traveled (VMT) per capita in the U.S. ticked up by 0.9 percent in 2014 compared to 2013, according to figures released on Thursday, March 12, by FHWA. Accounting for the effect of population growth, total miles driven increased by 1.7 percent. Chris McCahill and Eric Sundquist examine the economic and social trends at work and analyze which factors are likely to most heavily influence VMT in the coming years.
Nearby public transportation boosts property values, and increasingly cities are asking developers to help fund transit improvements that will benefit their projects. This report examines various value-capture methods used in four cities operating some of the largest and oldest transit systems in the nation, with the greatest backlogs of unfunded capital needs.
