In a recent study, researchers from Australia look closely at the relationship between parking demand and proximity and quality of service supply of public transit. When other socioeconomic factors were considered, the quality of transit service became much more important than proximity alone in determining parking demand. This will be helpful in the ongoing discussion about where and how to reduce or eliminate required parking as part of development.

Forecasters guarded about EV share of VMT
As transportation planners and environmental researchers look at climate policies, a smooth and equitable transition to a low-carbon global economy is an essential component. In the passenger vehicle sector, how will this process be affected by oil demand and EV adoption trends? A new report examines a number of EV penetration forecasts and summarizes the 2019 trends and their changes since 2018. The report focuses on passenger vehicles, which account for about 23 percent of oil demand. While other segments of the transportation sector—trucks, and aviation and shipping—account for about 29 percent of the oil demand, electrifying cars may be easier, according to the author.
As car commuting demand changes, highways and parking lots give way to development
Urban highways and plentiful surface parking lots, once considered essential, have outlived their promise in many large U.S. cities. Observers see growing interest in dense urban living, with some mobile segments of the population opting out of car-dependent suburbs. Bold cities have been redeveloping the areas opened up by highway removal, and developers are poised to profit from the development of surface parking lots within revitalizing urban cores.
On-demand transportation services as a complement of public transit
A recent article reports that on-demand transportation can complement existing transit and help cities reduce traffic by up to 15 to 30 percent. Emerging transportation technologies such as TNCs and on-demand transit apps have been much in the news, often with claims that TNCs are adding to urban congestion. In this study, an important conclusion is that the on-demand service can complement public transit networks.
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.
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.
Priced parking is fair and effective at lowering car use
New research out of California looks at the effect of priced parking on commuter mode choice and transportation costs for low-income households. Findings from two studies suggest raising the price of commuter parking by 10 percent could lower car use by as much as three percentage points and, while residential parking permits could hit low-income households hardest, few households would be disproportionately affected. Moreover, revenues from paid parking could offset any potential burden.
TRB provides playbook to TNC-transit partnerships
Transit agencies have increasingly partnered with transportation network companies, such as Uber and Lyft, to supplement fixed-route services. TNCs are used to extend service to less-dense areas of a community, provide first- and last-mile connections, operate on weekends or evenings, and for paratransit services. Until now, transit agencies have not had guidelines for the best way to set up these partnerships. A new TRB publication provides this guidance while outlining options based on the goals of both TNCs and transit agencies.
More evidence that TNCs are clogging downtown streets (and what NYC is doing about it)
In August, Uber and Lyft jointly released an analysis conducted by Fehr & Peers examining how their vehicles are contributing to VMT in six major cities: Boston, Chicago, L.A., San Francisco, Seattle, and Washington, D.C. The study found that Uber and Lyft vehicles account for just 1-3 percent of total VMT in the metro regions. However, they are contributing a significantly larger share in the core counties of several of these regions.
Overabundant parking fuels car-oriented living in greater Boston
A new report from the Metropolitan Area Planning Council reveals 30 percent of residential parking in the Boston area goes unused at night. This new study builds on an earlier report, featured in an SSTI webinar, growing the sample from 80 properties to 189 across 14 municipalities throughout the city’s inner core. The additional data also let MAPC test for significant factors affecting parking demand. MAPC estimates that the 5,910 empty spaces in their study represent $94.5 million in development costs, or roughly $5,000 per housing unit.
