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

SF TDM measures

This report proposes a new approach to assessing and responding to land use-driven transportation impacts, called “modern mitigation.” Instead of relying on auto capacity improvements as a first resort, this approach builds on practice around transportation demand management (TDM) to make traffic reduction the priority. Based on programs dating to the 1990s in several cities, a modern mitigation program requires certain new land uses to achieve TDM credits. Read More >

U.S. cities and developers beleaguered by too much parking, Mortgage Bankers report finds

Des moines parking

There are 83,141 households in the city of Des Moines, and 1.6 million parking stalls. Even allowing that some of those stalls are occupied by commuters, that’s a pretty staggering disparity. And even accounting for commuters, peak parking occupancy rates are only 65 percent downtown. These are some of the eye-opening findings from a new Mortgage Bankers Association report on parking supply in American cities. The report argues that localities should do their own parking inventories rather than rely on rules of thumb for parking needs and risk squandering resources. Read More >

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

Planning agencies and transportation decision makers often talk about the importance of improving access to destinations, but they rarely have the tools or resources to measure accessibility and incorporate those metrics into decision making. This report guides agencies through that process. Read More >

Connecting Sacramento

Connecting Sacramento is the first study to incorporate both accessibility analysis and tripmaking data, including data from multiple sources, and assess how they can be used together to guide transportation- and land use-related decisions. This study focused specifically on opportunities to improve first- and last-mile connections to light rail transit in Sacramento, but its findings are widely applicable. More Resources...

Growth near transit is key to connecting smaller cities, SSTI finds

A new study by SSTI and the Traffic Operations and Safety Lab at UW-Madison provides a partial roadmap to the future for transit in smaller cities. The study gave Eau Claire, Wisconsin—a city nearing 70,000 people—a look into emerging transit technologies and insight on their residents’ perspectives toward transit. SSTI also laid out a dozen future scenarios, evaluating each one using accessibility metrics. Read More >

More highways, more congestion

In pursuit of congestion relief, the United States added 63 percent more urban freeway lane-miles between 1990 and 2017. That rate far outstripped the 46 percent growth in urban population. It didn’t work. As widely reported last month, the Texas Transportation Institute’s Urban Mobility Report has returned after a five-year hiatus. Read More >

PennDOT CEO emphasizes community engagement, active transportation

Pennsylvania’s Secretary of Transportation wants more diversity in decision making; more equal concern for people walking, biking and driving; and more early communication with communities about PennDOT projects. These were the themes of an interview with Leslie Richards published last month in Governing. Read More >

AAA: Red light running is killing us

The AAA Foundation reports that fatalities due to red light running is at a 10-year high, and more than half of the deaths were outside the offending car, including pedestrians, bicyclists, and those in other cars. Read More >

Connectivity is good for walkability, but social factors also matter

Most efforts to increase bike and walk accessibility focus on physical access. But the built environment is not the full story. A new study finds that certain attributes of the social environment also greatly affect the perception of walkability, especially among people of color. Read More >
