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...

New mindset needed to address congestion, says MassDOT

A new report from the Massachusetts DOT dives into the state’s growing traffic congestion to understand the causes and potential solutions. It points to the rapid outward growth around Boston as one of the main causes, and suggests the current situation calls for bold new solutions aimed at connecting people and places while managing demand, rather than simply keeping roads moving.

Use of multimodal accessibility metrics in project prioritization and investment

The Accessibility Observatory at the University of Minnesota recently released a one-of-a-kind report that ranks the country’s 50 largest metropolitan areas (by population) according to accessibility to jobs via bicycle. The report is a product of a multi-year study, where the researchers analyzed land use and transportation systems to measure accessibility to destinations via different modes. The researchers also incorporated traffic stress and bicycle comfort in measuring accessibility. Read More >

E-bikes mean longer, more frequent bike trips

On June 18, the Madison, WI, bikesharing system became the first in the U.S. to switch its entire fleet to electric pedal-assist bikes, although other cities have been adding e-bikes to their fleet for several years. Results from a comparison of e-bike vs. standard bike usage show pedal-assist bikes may be the key to increasing bike mode share, especially as part of a city bikesharing program. In addition, recent studies also show that we are still getting plenty of exercise, even when getting help from the electric motor. Read More >

Autonomous boat “bridge” proposed in Amsterdam

A group of autonomous vessel developers is proposing a new way to move people through the unique urban-aquatic environment of Amsterdam. A small fleet of autonomous, electric boats (Roboats) is being designed to travel between the Marineterrein area and the city center, including the busy NEMO science museum. The potential use of autonomous technology here serves the dual purposes of increasing the accessibility of the area, by reducing the walk time by ten minutes, and showcasing this leading-edge technology.

Proximity to highways affects long-term school performance

A study from the National Bureau of Economic Research extends our knowledge of the effects of attending school near major roadways. Previous studies have found short-term effects on test scores, behavior, and school absences on days of poor air quality, but this new research shows that long-term school performance and test scores can be affected by attending school downwind of highways.
