Sweden and Virginia: Messaging and variable tolls can influence mode choice

Two recent studies demonstrate two approaches to reducing driving. A Swedish study looked at what types of messages influence the choice to drive, while a report from Virginia shows that tolls on the I-66 corridor outside Washington have made a difference in both mode choice and when drivers travel.

Does Uber impact bike-share usage? Evidence from a natural experiment in Budapest

Significant research has gone into understanding the relationships between different urban transportation options and whether they support or compete with each other. It seems reasonable to think ride-hailing services like Uber might compete with bike sharing in urban areas, but findings from a recent study in Budapest suggest the opposite.

Impact of “new age” shopping behavior on VMT and the environment

There have been a number of studies studying the relationship between in-store and online shopping behavior and its impact on retail-related travel. A broadly accepted idea is that online shopping, in more ways than one, is substituting for in-store shopping and can thereby reduce shopping related travel. However, major demographic and economic factors affect shopping behavior, and expedited delivery options may reduce the potential of e-commerce to reduce VMT and greenhouse gas emissions.

In Silicon Valley, private shuttles not just for tech workers anymore

A recent article from Protocol, a newsletter devoted to the tech industry, details the twin and intertwined problems of very long commutes and the lack of adequate housing in Silicon Valley. Most of us have heard of the so-called “Google buses,” but these shuttles now carry factory workers as well as well-paid white collar programmers.

The argument for ending single-family zoning

An article in the latest issue of the JAPA makes a case for getting rid of single-family zoning in U.S. cities. The authors argue that single-family zoning exacerbates inequality and promotes the inefficient use of valuable urban land. By excluding other types of development, R1 zoning produces a housing scarcity in desirable places, which pushes prices up and excludes all but wealthy residents.

Researchers say investment in infrastructure has the potential to move short trips out of cars

Can the rise of new personal mobility options lure drivers out of their cars for short trips? Several recent reports say, “yes,” but only if cities resolve both infrastructure and legal issues surrounding their use. At the same time, examination of walking and biking rates from 2001 to 2017 show that better infrastructure and policies are needed to help them supplant driving for short trips. However, cities that have invested in infrastructure have seen a dramatic rise in active transportation.

Findings from Toronto: Sticks and carrots for TNCs

We have a lot of evidence that venture capital-subsidized transportation network companies are cannibalizing transit and driving up VMT. Now a new study of this phenomenon examines the patterns of TNC trip making and suggests a system of taxes and subsidies in response. The paper, which employs data from a 2016 personal transportation survey, finds that TNC trips that could reasonably be taken on transit tend to occur during peak hours and for non-work trip purposes. Given policy concerns for maintaining transit ridership and reducing auto congestion and emissions, the authors suggest penalizing these TNC trips with higher fees.
