Local governments often have jurisdiction over public transit authorities. Many of these entities have the mission of providing safe, accessible, and affordable mobility options for their residents. From extensive shuttle services to new rail infrastructure, local officials have the power to shape their communities with reliable modes of commute. Help from city planners, environmental scientists, social workers, and countless other industries can contribute to decisions that decrease the carbon impact and air pollution caused by transportation. Technological innovations ranging from high-speed rail, to autonomous vehicles, to ride-sharing mobile apps are increasing the complexity of local decision-making and the need for STEM-informed input.
