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 >


FEATURED RESOURCE

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...

VMT moderates after recession-driven swings

U.S. vehicle-miles traveled, which had declined during the recession and then spiked, returned to a more normal level in 2018. According to FHWA’s Travel Monitoring Trends data, total VMT grew by 0.4 percent in 2018. That rate was slower than population growth, resulting in a slight decline in VMT per capita. Read More >

A tool to estimate the added VMT from highway expansions

Since passage of S.B. 743 in 2013, California agencies have wrestled with questions around the added travel and emissions resulting from land use and transportation projects. On the land use side, see SSTI’s recent webinars about land-use review reforms in San Jose and Pasadena. On the transportation side, the National Center for Sustainable Transportation has developed an induced travel demand calculator designed to calculate the percentage of additional annual VMT when highways are widened.

Lessons from nine states bringing ‘practical solutions’ from policy to practice

Smart Growth America recently concluded two years of technical assistance with nine state DOTs. The projects focused on “Accelerating Practical Solutions,” and addressed practices that hold back DOTs from consistently building lower-cost and context-sensitive projects. SGA has developed seven white papers based on key changes DOTs are making. Read More >

Methodology for prioritizing streets for multimodal treatments

Building Complete Streets can assure that our transportation network is safe and comfortable for all road users: people biking, walking, and taking transit, as well as drivers of cars. But which streets are most appropriate for Complete Streets treatments—to encourage non-driving modes and maximize the safety of people using these modes—can be a tough question to answer. A recent journal article describes the prioritization methodology used in Quebec City for making these decisions. Read More >

Larger cities offering TNC trips to improve transit options

As transit ridership continues to fall in urban areas nationwide, several cities are turning to an unlikely ally to make transit service more appealing and convenient: TNCs. Although in the past smaller cities with less robust transit have used TNCs to fill in the gaps, larger cities are now jumping on board. Read More >
