The effect of front-end vehicle height on pedestrian death riskJanuary 29, 2024Abstract: Pedestrian deaths in the US have risen in recent years. Concurrently, US vehicles have increased in size, which may pose a safety risk for pedestrians. In particular, the increased height of vehicle front-ends may present a danger for pedestrians in a crash, as the point of vehicle contact is more likely to occur at… Read More
New publication by Justin Tyndall in the Economics of TransportationJanuary 29, 2024In a new publication in the Economics of Transportation by Justin Tyndall, "The effect of front-end vehicle height on pedestrian death risk," Tyndall tests for the effect of taller vehicles on pedestrian outcomes in crashes using vehicle design measurements. Using recent crash-level data, Tyndall shows that a pedestrian hit by a full-size SUV is twice as likely to… Read More
The Effect of Front-end Vehicle Height on Pedestrian Death RiskJanuary 12, 2024Pedestrian deaths in the US have risen in recent years.

The effect of bus rapid transit on local home pricesDecember 1, 2023Abstract: Bus Rapid Transit (BRT) systems have become increasingly common in US cities. BRT stations provide a local amenity by improving transportation options for local residents, but may also represent a local nuisance due to noise or displacement of other road users. We estimate whether BRT is priced into local real estate by studying a… Read More

Highways and pedestrian deaths in US neighborhoodsAugust 8, 2023The research makes use of a national database on vehicle crashes. You can explore the data yourself using UHERO's Fatal Car Crash Explorer. Abstract: Over 100,000 pedestrians have been struck and killed by vehicles on US roadways in the first two decades of the 21st century, representing an alarming public health issue. We examine the… Read More
Justin Tyndall awarded the Stough-Johansson Springer Award for research in pedestrian safetyFebruary 20, 2023Congratulations to Justin Tyndall, whose joint work with Cody Nehiba was awarded the Stough-Johansson Springer Award. Their paper, titled "Highways and Pedestrian Deaths in US Neighborhoods", was deemed the best paper presented by an early-career scholar at the 62th Annual Meeting of the Western Regional Science Association. Each year the Springer Prize is awarded for the best paper… Read More
UHERO’s Justin Tyndall’s “case for taxing large vehicles” receives national media attentionDecember 8, 2022UHERO’s Justin Tyndall's recent publication in Economics of Transportation has received national media coverage, including Medium, Streetsblog, Financial Times, and Vox. Using data covering fatal vehicle collisions in the US and exploiting heterogeneity in changing vehicle fleets across metros for identification, Tyndall estimates that replacing the growth in Sport Utility Vehicles with cars would have… Read More
Does air pollution increase electric vehicle adoption? Evidence from U.S. metropolitan areas, 2011–2018April 15, 2022A publication in the Journal of Environmental Economics and Policy by a team of economists including UHERO’s Coffman, Hayashida, and La Croix shows that changes in local air pollution within U.S. metropolitan areas are associated with changes in consumer purchases of new EVs. The authors find a positive association between PM2.5 pollution and BEV adoption, and a negative… Read More
Blog: Improving Pedestrian Safety in HawaiʻiAugust 12, 2021By Justin Tyndall Over 2,500 people have been killed in motor vehicle crashes in Hawaiʻi since 2000, averaging a person every three days. Car crashes are a leading cause of accidental death, particularly for younger people. In a different setting, this scale of mortality might be treated as a public health emergency, but we have… Read More
The local labour market effects of light rail transitJuly 1, 2021Many US cities have made large investments in light rail transit in order to improve commuting networks. I analyse the labour market effects of light rail in four US metros. I propose a new instrumental variable to overcome endogeneity in transit station location, enabling causal identification of neighbourhood effects. Light rail stations are found to drastically improve… Read More
Traffic in Honolulu: How to Make Transitory Pandemic Gains PermanentApril 26, 2021By Justin Tyndall and Sumner La Croix During the COVID-19 pandemic, Honolulu traffic became much less congested. Local and state governments could help residents keep the social benefits from traffic control by providing incentives to private firms to stagger hours and/or keep more employees working at home. A congestion zone fee to drive within the downtown-to-Waikiki corridor… Read More
Cycling mode choice amongst US commuters: The role of climate and topographyOctober 28, 2020Cycling to work is uncommon in most areas of the US, but relatively common in a particular set of metros and neighbourhoods. Explanations for this spatial heterogeneity often focus on differences in local geography, with some areas being allegedly more suitable for cycling. Tyndall estimates the role of topography and climate in determining the share of a metro’s workers who… Read More
Pedestrian Deaths and Large VehiclesOctober 20, 2020Abstract: Traffic fatalities in the US have been rising among pedestrians even as they fall among motorists. Contemporaneously, the US has undergone a significant shift in consumer preferences for motor vehicles, with larger Sport Utility Vehicles comprising an increased market share. Larger vehicles may pose a risk to pedestrians, increasing the severity of collisions. I… Read More
EV driver characteristics: Evidence from HawaiiMarch 1, 2020Electric vehicles (EVs) offer an opportunity to dramatically decrease greenhouse gas emissions within the transport sector if fueled by renewable energy. Hawaii had been early-on considered an ideal place to launch new EVs because of the limited driving range of its island geography. Though it ranks second in new EV registrations per capita in the… Read More
