In its 67-page ruling in May 2015, the federal Surface Transportation Board noted: "The current transportation system in the San Joaquin Valley region has not kept pace with the increase in population, economic activity, and tourism. ... The interstate highway system, commercial airports, and conventional passenger rail systems serving the intercity market are operating at or near capacity and would require large public investments for maintenance and expansion to meet existing demand and future growth over the next 25 years or beyond." Thus, the Board sees the HSR system as providing valuable benefits to the region's transportation needs.
