| Abstract: | In this study, the researchers examined traffic volumes and patterns in Yosemite Valley, the heart of Yosemite National Park. The purpose of this analysis was to understand which destinations attract the most visitors and to analyze how visitors move around the park on foot, by bike, and by car. Aggregated cell phone location data accessed through the StreetLight Data platform was used to produce vehicle volumes and indexes of bicycle and pedestrian volumes. This analysis reveals noteworthy patterns of travel for each mode with respect to weekdays versus weekends and times of day. An analysis of trip origins and destinations for each mode shows that drivers generally make longer trips than visitors who walk or bike, but that many driving trips are relatively short. Vehicle counts are higher in the core area of the valley than on the roads into and out of the valley, suggesting that most drivers circulate between valley destinations rather than parking and using other modes. Short distance trips by car could be a target for efforts to replace driving with walking and bicycling. This analysis can help to inform transportation planning in Yosemite Valley, particularly with respect to the bicycle network and potential changes to and expansion of the bike share service overseen by the Yosemite Conservancy. As a follow-up to this analysis, the research team plans to conduct an intercept survey of visitors to Yosemite Valley to better understand their choices about travel within the valley, especially their choices about bicycling.

| Abstract: | We estimate the causal effect of shared e-scooter services on traffic accidents by exploiting variation in availability of e-scooter services, induced by the staggered rollout across 93 cities in six countries. Police-reported accidents in the average month increased by around 8.2% after shared e-scooters were introduced. For cities with limited cycling infrastructure and where mobility relies heavily on cars, estimated effects are largest. In contrast, no effects are detectable in cities with high bike-lane density. This heterogeneity suggests that public policy can play a crucial role in mitigating accidents related to e-scooters and, more generally, to changes in urban mobility. |

| Abstract: | The social costs of pollution and climate change hinge critically on humans’ ability to adapt. Based on transaction records from the world’s largest payment network, this research compiles daily travel flows and documents that China's rapid expansion of high-speed railways (HSR) facilitates the use of intercity travel as an effective adaptation strategy. Access to HSR reduces travelers' exposure to extreme air pollution and temperature by 7% and 10%, leading to substantial health benefits. These reductions are attributed to both contemporaneous responses to unexpected adverse conditions and also longer-horizon changes in travel patterns. |

| Abstract: | With China’s 2001 WTO accession, trade costs between the US and China fell sharply, but the transport costs of Chinese imports within the US remained sizable. We argue that domestic transport costs shield local labor markets from globalization. Using a shift-share design for industry-level Chinese imports across 42 ports of entry, we show that US job losses from competing imports occurred near the ports where they arrived. Once accounting for domestic transport costs, import competition affects coastal areas more than inland areas; shows larger impacts in housing markets and indirectly affected jobs; and explains voting, mortality and family formation |
