This document discusses funding transportation projects through revenue generation and efficiency. It examines San Diego's TransNet program, which generates $3.3 billion over 20 years through a half-cent sales tax. The funds are distributed equally among transit, highways, and local roads. It supports a robust public transportation system through projects like new bus rapid transit. The program also includes $850 million for environmental mitigation and a $280 million smart growth incentive fund. Going forward, the document recommends stabilizing existing assets, investing according to the state framework, advocating for expanded revenue sources, and developing new funding structures.
