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...

Places with most crash exposure also fear enforcement bias

Low-income and minority Americans face a dilemma: They are disproportionately victimized by our transportation system. And while law enforcement could help, those same Americans are subject to profiling and fines that can lead to economic ruin. SSTI’s mid-November Community of Practice meeting, attended by CEOs and top staff from a dozen state DOTs, took on this problem. Jill Locantore, executive director of Walk Denver, gave us permission to share her presentation, and we can also summarize the thrust of the conversation. Read More >

LOS to play more limited role in California planning, according to survey

A new survey of planning officials in California finds that most are embracing the shift from highway level of service to vehicle miles traveled for evaluating the environmental impacts of new development projects. While some are ditching LOS altogether, however, many still rely on it to measure traffic impacts. Read More >

How might travelers behave with privately-owned AVs?

In many ways, we can only speculate about a future with autonomous vehicles on the road. The effects on vehicle miles traveled are expected to be very different if AVs are privately owned versus shared. A recent post on Jalopnick reviews a study published in 2018, that focuses on the question of individual ownership. The results point to a potential worst-case-scenario; a catastrophic increase in VMT that could occur with the introduction of privately-owned AVs. Read More >

App cuts double parking by delivery drivers in DC

Like many cities, Washington, DC, has a problem with double parking and delivery vehicles blocking crosswalks and bus and bike lanes. One experiment in curb management showed good results during its trial run from August to October. Using the curbFlow app, delivery drivers can book an appointment for a loading zone up to 30-minutes in advance. Double parking and illegal U-turns went down 64 percent in the nine zones where it was tried. Delivery drivers like it as well, as they reported that they received fewer parking tickets and avoided circling the block looking for a legal spot. Read More >

Why didn’t the turtles cross the road?

A study from Ohio University evaluating the impacts of a new bypass on Eastern Box Turtles found unexpected results: turtles living next to the bypass did not exhibit heightened stress levels, but not one of them crossed the road over a two year period, including via a culvert. Read More >
