Bikeshare Usage Change in New York City Due to COVID-19 Pandemic
Bikeshare use in New York City dropped substantially during the initial months of the COVID-19 pandemic, but by summer of 2020 had largely recovered to pre-pandemic levels. The patterns of usage, however, have changed.
Research: Variation in ride-hailing trips in Chengdu, China
A new paper looks at the elasticities of demand for ride-hailing service provider DiDi in Chengdu, China.
Trip patterns and revenue of shared e-scooters in Louisville, Kentucky
Data on shared e-scooters in Louisville, Kentucky are analyzed.
Has the Great Recession and its Aftermath Reduced Traffic Fatalities?
An analysis of state-level data from 1984 to 2014 provides evidence on the relationship between economic recessions and US traffic fatalities.
A rejoinder to the critique of “Costs and Benefits of a Road Diet Conversion”
A response to the six points made by Le Vine and conclude with a brief critique of existing practice.
An Evaluation of Transit Procurement Training
We evaluated a training course called “Orientation to Transit Procurement”, designed and conducted by the National Transit Institute.
Attitudes towards transit-oriented development: Resident experiences and professional
The question addressed here is how, if at all, TOD and TOD-proximate residents’ perceptions of the benefits and shortcomings of TOD are perceived and addressed by professionals involved with TOD planning and development.
Measuring Benefits of Transit Oriented Development
This study provides an overview of the beneficial impacts of transit-oriented development – compact, mixed-use pedestrian land uses within walking distance of transit stations.
Transit-oriented development and the frequency of modal use
The analysis presented here examines the frequency of using these modes of travel for those living in TODs and proximate to a train station versus those living more distantly.

GPS-Based Street-View Greenspace Exposure and Wearable Assessed Physical Activity in a Prospective Cohort of US Women
Background Increasing evidence positively links greenspace and physical activity (PA). However, most studies use measures of greenspace, such as satellite-based vegetation indices around the residence, which fail to capture ground-level views and day-to-day dynamic...
Measuring Induced Travel Elasticities associated with Local Roads from Trip Generation
Induced travel elasticities associated with new road capacity are typically estimated for roads of higher functional classifications, such as interstate freeways and principal arterials. These are estimated as “own” elasticities, that is an increase in lane kilometers...
