The American Public Transportation Association (APTA) is recommending that Congress increase its funding of transit systems in the U.S. by $11.5 billion per year.
The association announced on Tuesday at its annual conference in Washington, D.C., that it was proposing that Congress approve $100.4 billion in new public transportation spending when the current funding for road and transit projects runs out this fall.
The current congressional surface transportation bill is scheduled to expire in September, and the trust fund that pays for most of its infrastructure initiatives is projected to go bankrupt as soon as August.
APTA President Michael Melaniphy said the funding for transit systems should be increased in the new round of transportation funding that Congress is debating now.

Transportation Secretary Anthony Foxx said Thursday that lawmakers should stop focusing on trying to refill the trust fund that pays for road and transit projects.
Instead, Foxx said in a speech to the U.S. Chamber of Commerce, lawmakers should train their efforts on coming up with a new funding source for transportation projects altogether.
"For years, our national dialogue has focused on how to get the Highway Trust Fund leveled off," Foxx said. "To translate that into business terms, we’ve been trying to reach the same level of sales revenue and expenditures as the last year instead of growing revenue and expenditures to meet customer demand."
The new fund is separate from the climate change agenda announced in June.
