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...

Researchers re-evaluate how we value transportation

Transportation agencies and metropolitan planning organizations often wrestle with how to properly value transportation investments, especially when it comes to things that can’t be measured in terms of vehicle delay, such as multimodal access and environmental justice. Some of these challenges are tackled in a new issue of Research in Transportation and Business Management, edited in part by SSTI. Those familiar with SSTI’s recent work in the development and implementation of accessibility metrics may be interested in a paper describing a new measure of non-work accessibility. Read More >

Chicago opens TNC data to the public

Getting data from transportation network companies for planning and other purposes has been a challenge. Agencies want to understand where TNCs are operating in order to address curb management, congestion, and transit-cannibalization issues. But TNCs have viewed such data as proprietary and have been reluctant to share. Chicago, however, has an advantage over many cities in this area, due to its per-ride TNC tax established four years ago. Now the city has made that data public. Read More >

NYSDOT chooses the grid for Syracuse freeway replacement

After 10 years of community meetings, studies, and fierce debate, the New York State DOT has chosen the “community grid” as the preferred alternative for I-81 through Syracuse. The elevated viaduct had reached the end of its useful life and did not meet modern standards for an interstate. Instead of an elevated viaduct, the corridor will become an urban boulevard connected to local streets. Syracuse is not the first city to see an elevated freeway come down, and it likely will not be the last, including in the state. New York will soon have to make a decision on what to do about the Brooklyn-Queens Expressway. Read More >

Oregon regulators require public utilities to adopt plans for electric vehicles

While electric vehicles only make up a small share of the current U.S. vehicle fleet, by 2040 they are expected to comprise approximately 55 percent of all new vehicle sales. Accommodating for growing EV demand, however, will require major changes in how utilities supply electricity. At the moment, the electrical grid is simply not equipped to handle widespread EV adoption. In Oregon, regulators are attempting to address this problem. Read More >

Sidewalk evaluation app Project Sidewalk launches in Seattle

Project Sidewalk, newly launched in Seattle, is crowdsourcing the evaluation of sidewalks and ramps with the intent to help DOTs locate and prioritize needed repairs and improvements, educate the public, and collect data to train AI. Poorly planned sidewalks and ramps, those in disrepair or with other impediments can dramatically reduce the mobility of people with disabilities and decrease walking accessibility. The gathered data could eventually be incorporated into interactive routing software such as Access Map, which is aimed primarily at helping sidewalk users maximize their mobility. Read More >
