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...

Spending smarter: lessons and opportunities for state DOTs

Two states that are changing how transportation investments are prioritized were featured recently on an SSTI webinar. Virginia just funded a third round of projects under its Smart Scale program, while Hawaii piloted its own SmartTRAC program with help from SSTI and Smart Growth America. SSTI will soon be launching a new project to learn from these past experiences and guide future programs, and we invite interested agencies to reach out. Read More >

Why cities aren’t preparing for autonomous vehicles

A study evaluating municipal planning for autonomous vehicles found that an overwhelming majority of cities have done little to prepare for their arrival. At the same time, many of those cities have concerns about the negative impacts AVs could bring along with the substantial benefits, from increased vehicle miles traveled and congestion to reduced transit ridership and increased sprawl.

AVs: Some intersections may get more dangerous before they get safer

Many imagine a future with fleets of autonomous vehicles seamlessly traversing road networks, wirelessly connected, perfectly aware of their surroundings and other vehicles, expertly avoiding conflicts. But what happens during the transition from manually-driven to fully-autonomous cars? As the share of AVs increases, some intersections may get more dangerous before they get safer, says a new paper by Australian researchers. Read More >

TDM best practice: Shout out to Greater Richmond Transit Company

In an era of falling transit ridership and utopian sustainability goals, Richmond, Virginia, seems to have hit the nail on the head. With the introduction of a bus rapid transit line and an overall bus system redesign, the Greater Richmond Transit Company has increased transit ridership in the region by 17 percent. GRTC’s distinctive carpooling and vanpooling system has grown extensively in the past decade. A recent article by Mobility Lab explains in detail the reasons and strengths behind GRTC’s continued success. Read More >

Why are they Snapchatting while driving, and what will get them to stop?

A study from Australia gives some insights into use of social media while driving, looking not just at the incidence, but also what deters the behavior. But while the study began as a general look at use of all social media by young drivers, it ended up focused on the use of Snapchat as the most common mobile phone behavior in the car. Read More >
