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...

Was 2018 the year of peak ICE?

With slowing growth in light-duty automotive markets overall, and an increasing share of electric vehicles within that market, last year may have been the high point for internal combustion engines. Such is the conclusion drawn by Financial Times, based on interviews with and reports from a variety of automotive industry experts. Read More >

The hype cycle of autonomous vehicles

Several recent articles have addressed a significant shift in public perception toward autonomous vehicles over the course of 2018. While some studies and reports pointed out the challenges AVs are likely to pose to communities, or raised skepticism about the rosier claims around safety, timing, and level of adoption, in general transportation industry and public expectations were high. However, 2018 was a bad year for AVs.

Seattle moves to new transportation level of service guidelines

Seattle is the latest city to move away from traditional definitions of motor vehicle LOS and toward a more multimodal approach in assessing the impacts of new development. On January 14, the Seattle Council is set to vote on new regulations for developments to support changes in adopted transportation level of service. The new regulations will change which development projects require transportation mitigation and increase the minimum size of developments that are subject to a transportation impact analysis.

Tolling strategies may mitigate the impact of AVs on VMT and congestion

The anticipated shift to autonomous vehicles raises several concerns, among them are whether AVs will increase total vehicle miles traveled, exacerbate congestion, or replace the use of transit and active modes. A new study focused on Austin, TX, models the effects that two adoption scenarios may have, comparing the results to current conditions. The experiment shows a jump in VMT, increased congestion, and a shift away from public transportation. The authors then mitigate the scenarios by applying four tolling schemes, and examine the results. Read More >

Mileage-based fee more effective than California’s new ZEV fee

California is among the states that have added a special registration fee for zero emission vehicles. However, research commissioned as part of the enacting legislation casts doubt on the efficacy of the fee in paying California’s infrastructure costs, instead pointing to a road user charge as the most effective solution.
