The main purpose of this legislation is to increase funding for small cities that have a high reliance on public transit. The goal is to support and improve transit services in these communities, making it easier for residents to access transportation options. The key provision of this law is a change in the formula used to allocate federal grants to small transit-intensive cities. Specifically, it raises the percentage of funding these cities receive from 3 percent to 5 percent. This adjustment aims to provide more financial resources to enhance transit systems in smaller urban areas.
