EVENT OVERVIEW: Bike-share services offer cities a new transportation option with the potential to improve environmental, social, and health outcomes by increasing physical activity and reducing vehicle miles traveled and related greenhouse gas emissions. But these benefits accrue only if bike-share use replaces car travel. Little is known about the factors influencing whether bike-share substitutes for driving. In this webinar, researchers will share results of a study based on user surveys and system-wide trip data from a Sacramento-area dockless, electric bike-share program in 2018 and 2019. The researchers will present estimates of system-wide reductions in vehicle miles traveled caused by bike-share. They will also share modeling work that examines factors influencing bike-share demand and estimates the impact of hypothetical expanded service scenarios.
