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...

Short commutes and multimodal access motivate housing choices

In choosing where to live, people strive for a combination of short driving commutes and good transit access, according to a new study spanning three large regions: Atlanta, Seattle, and Detroit. Walkable neighborhoods are also a plus, depending on the region. Read More >

Toward transportation equity

Many observers see the transportation profession—and other professions, when examined in the light of current knowledge—as being built on a foundation of exclusion. Now, the three E’s of ethics, equity, and empathy are emerging to guide the standard E’s of engineering, education, and enforcement. Read More >

In Silicon Valley, private shuttles not just for tech workers anymore

A recent article from Protocol, a newsletter devoted to the tech industry, details the twin and intertwined problems of very long commutes and the lack of adequate housing in Silicon Valley. Most of us have heard of the so-called “Google buses,” but these shuttles now carry factory workers as well as well-paid white collar programmers. Read More >

The argument for ending single-family zoning

An article in the latest issue of the JAPA makes a case for getting rid of single-family zoning in U.S. cities. The authors argue that single-family zoning exacerbates inequality and promotes the inefficient use of valuable urban land. By excluding other types of development, R1 zoning produces a housing scarcity in desirable places, which pushes prices up and excludes all but wealthy residents. Read More >

The incompatibility of Vision Zero and VMT growth

The U.S. transportation field has tried many things to reduce traffic crashes, fatalities, and injuries: drunk-driving and seatbelt laws; in-vehicle safety improvements; wide, straight roads with crash zones; graduated licensing; and more. Yet traffic crashes still kill 35,000-40,000 Americans each year and injure millions. A new online resource that helps explain the situation. Fatalities are largely a function of miles driven, so you can’t be serious about Vision Zero without also being serious about VMT management. Read More >
