While most known for buses and trains, many transit agencies are exploring how to incorporate on-demand Microtransit services into their offerings. However, driver shortages and low capacities per vehicle can make on-demand service a challenging investment, especially at scale. AVs, which are reaching full maturity, will be key to expanding on-demand transit service while maintaining costs at a manageable level. Microtransit is an updated form of shared, on-demand public transportation that uses an app to book rides in selected service zones. Microtransit will be an important gateway for many in the community to start to use public transit of all modes.
