Graduated driver licensing with mandated driver training in Ohio is associated with fewer serious injury and fatal crashes among young novice drivers

Urban Roadway in America
We predicted the amount, share, and value of land dedicated to roadways within and across 316 U.S. primary metropolitan statistical areas. Despite the amount and value of land dedicated to roadways, our study provides the first such estimate across a broad range of metropolitan areas. Our basic approach was to estimate roadway widths using a 10% sample of widths provided by the Highway Performance Monitoring System and apply our estimates to the …
Should Environmentalists Support the Gasoline Tax
Taxes on gasoline and diesel reduce vehicle travel by making driving more expensive -the price effect.But fuel tax revenue is used to build and widen urban highways, inducing more driving -the capacity effect.We show that in the United States, the capacity effect over the 1981-2021 period was more than five times greater than the price effect.As the rise of electric vehicles forces policymakers to consider replacing or supplementing fuel taxes, o…
A global analysis of land use regulation, urban form, and greenhouse gas emissions
Cities feature prominently in debates over the existential threat of climate change. Research on urban sustainability, however, has too long been based on national studies from data-rich regions of the world. Fortunately, that is changing as globally harmonized datasets enable new comparative analysis of urban areas. This paper uses new data to address the question - how does urban land policy relate to urban form and greenhouse gas emissions? We…
Impact of TNC on travel behavior and mode choice
How do low-income commuters get to work in US and Mexican cities? A comparative empirical assessment
This paper applies multinomial logit models to examine how metropolitan urban form, housing type and socioeconomic factors covary with individuals’ commute mode choice for 1.2 million low-income workers in the USA and Mexico. Comparing the commute patterns of low-income households across the USA–Mexico border sheds light on the consistency of estimated relationships across global contexts and the likely transferability of transportation and land …
Compact cities and economic productivity in Mexico
This paper examines the contingent nature of agglomeration economies. Existing empirical evidence that compact cities are more productive is mostly from countries and regions with highly productive service sectors, such as the USA or Europe. We hypothesise that this relationship will differ in countries where land-intensive manufacturing activities are more productive than services. In this paper, we test this hypothesis using data from the 100 l…

Do Denser Neighborhoods Have Safer Streets? Population Density and Traffic Safety in the Philadelphia Region
This study uses multilevel negative binomial models to investigate relationships between neighborhood socio-demographics, urban form, roadway characteristics, traffic collisions, injuries, and fatalities on the Philadelphia region’s streets from 2010 to 2014. We pay particular attention to neighborhood population density. Results indicate that streets in denser neighborhoods have fewer overall collisions, injuries, and fatalities. The association…
The Philadelphia story
We examine changes in travel behavior in the Philadelphia region between 2000 and 2012. We use two household regional travel surveys over a decade apart, the 2000 and 2012 surveys, from the Delaware Valley Regional Planning Commission (DVRPC). Previous research, at the national scale, has highlighted changes among the Millennial cohort. We use these two regional datasets to examine the changing travel behavior among Millennials and to put these c…
Residential location, urban form, and household transportation spending in Greater Buenos Aires
Urban sprawl and the growing geographic scale of segregation in Mexico, 1990–2010
Intersecting Residential and Transportation CO 2 Emissions
This article uses a series of fixed-ratio projections and scenarios to explore the potential for local residential energy conservation mandates and compact growth programs to reduce locally based CO 2 emissions in eleven representative US metropolitan areas. Averaged across all eleven metros, residential energy conservation mandates could reduce residential CO 2 emissions in 2030 by an average of 30 percent over and above 2010 levels. In terms of…

The geography of car ownership in Mexico City
Suburbanization and car-ownership have increased rapidly in developing-world cities over the past half-century. This study examines the relationship between income, car ownership, and suburbanization across geographies and households in metropolitan Mexico City. Neither car-ownership trends by geography nor a mixed logit model of 43,000 households’ joint car-ownership and residential-location decisions suggest that car ownership and suburbanizati…
Planning for Cars That Drive Themselves
Through a review of long-range transportation plans and interviews with planners, this article examines how large metropolitan planning organizations are preparing for autonomous vehicles. In just a few years, the prospect of commercially available self-driving cars and trucks has gone from a futurist fantasy to a likely near-term reality. However, uncertainties about the new technology and its relationship to daily investment decisions have kept…
The Built Environment and Car Use in Mexico City
This article explores differences in the relationship between the built environment and households’ car use in Mexico City in 1994 and 2007. After controlling for income and other household attributes, population and job density, transit and highway proximity, destination diversity, intersection density, and accessibility are statistically correlated with households’ weekday car travel in Mexico City. These correlations are generally stronger tha…
Half-Mile Circle
The 0.5-mile distance has become accepted for gauging a transit station's catchment area in the United States and is the de facto standard for the planning of U.S. transit-oriented developments (TODs). Planners and researchers use transit catchment areas not only to make predictions about transit ridership and transit impacts (socioeconomic and on land use) but also to prescribe regulations (e.g., relaxing restrictive zoning or carving out TODs f…
To T or Not to T
The debate over the costs and benefits of rail passenger transit is lively, deep, and often ideological. As with most polemical debates, the truth probably lies somewhere in the middle of extreme views. Some rail systems have benefits that outweigh their costs, while others do not. Applying a commonly used transit-fare price elasticity to 24 of the largest light and heavy rail systems in the United States and Puerto Rico, assuming a linear demand…
