Modernizing Mitigation: A Demand-Centered Approach (SSTI, September 2018)

Cities exist to provide people and firms with access to goods, services, employment, and other people. A mark of a city’s success is the clustering of complementary land uses to residents’ and businesses’ mutual benefit; the more people and activities within reach of each other, the greater

Guidebook for Measuring Multimodal Network Connectivity (FHWA, February 2018)

Active transportation works best when networks are well-connected and destinations compactly arranged. Yet while the field has standard metrics and methods for many other aspects of the transportation system, it performs connectivity analyses as one-offs or not at all. FHWA’s new guide

Pedestrians First: Tools for a Walkable City (ITDP, 2018)

The Institute for Transportation and Development Policy recently released Pedestrians First: Tools for a Walkable City. The toolkit, aimed at governments, city planners, NGOs, and developers, notes that “Walkability is the foundation of any type of transportation; all trips require walking at

Connecting Sacramento

New tools and data sources have begun to change the way we think about and plan for meeting people’s transportation needs. Accessibility analysis lets us measure transportation performance in terms of people’s ability to reach destinations instead of simply how fast cars move or whether

Accessibility in practice (SSTI and Virginia Office of Intermodal Planning and Investment, 2017)

Trip-making data, TDM, and connectivity in Northern Virginia (SSTI and Michael Baker International, 2016)

Commercially available GPS data offers valuable new insight about trip origins, destinations, and routes, including short trips that travel demand models often cannot capture. Using this data, SSTI worked with Michael Baker International, the Virginia DOT, and local stakeholders to identify

Linking Transit Agencies and Land Use Decision Making: Guidebook for Transit Agencies (TRB, 2016)

Land use decisions play a key role in shaping the long-term success of virtually every transit system in the United States. Organizations other than transit agencies hold the responsibility and authority for integrating land use and transit. However, transit agencies can influence the framework

Trip-making and accessibility: New tools, better decisions (SSTI, 2016)

Transportation researchers and practitioners have long sought other tools to complement or perhaps replace conventional methods—tools that would better analyze trips rather than speed at points in the system, speak to non-auto modes of travel, address land use solutions as well as highway

Growing a Culture of Transportation Sustainability in Massachusetts (McCahill, Ebeling and Codd, 2014)

The transportation sector is a growing focus of sustainability efforts, given the large scale of its impacts, and yet it remains one of the more difficult sectors to reform. Private automobiles powered by petroleum-based fuels dominate transportation in the U.S. and the primary mission of most

Effects of Parking Provision on Automobile Use in Cities: Inferring Causality (McCahill, Garrick, Atkinson-Palombo and Polinski, 2015)

In a paper presented at the 2016 TRB Annual Meeting, SSTI Senior Associate Chris McCahill and colleagues from University of Connecticut examined the cause and effect of parking and driving habits. Automobile use has been on the rise in cities for nearly a century and so has the supply of
