“Induced demand” is the idea that building and widening roads doesn’t make traffic better–it makes it worse. Late last year Caltrans finally acknowledged that, yeah, it’s probably true that all the work they’ve been doing for the past few decades has been for naught.
Not everyone got the memo. The Valley Transportation Authority (VTA)’s proposed half-cent sales tax, which is supposed to fund everything from buses to Caltrain to bicycle routes, could also open the floodgates to billions of dollars in continued highway expansion. That’s because Palo Alto, Mountain View, Sunnyvale, Los Altos, Los Altos Hills, Cupertino, Campbell, Saratoga, Los Gatos, and Monte Sereno have included a total of $1.5 billion in auto traffic capacity expansion projects in their draft proposals on where to spend the money [PDF]. That means $1 billion will go to county expressways and another $500 million on state highways and local arterial roadways.
San Jose’s funding priorities [PDF] include $650 million countywide for reconstructed highway interchanges “to support economic development,” including $320 million for six expanded interchanges. Even more money could be sunk into traffic capacity expansions on city streets via a “local streets and roads” category intended for repaving but which also can include lane additions and signal modifications. The North County and West Valley cities have proposed $1 billion for local streets and roads, while San Jose has proposed $1.8 billion.
In other words, more and more asphalt.
“As a voting member of the VTA Board of Directors, I think expressways are extremely important,” said San Jose City Council member Johnny Khamis at the city’s February 9 review of the sales tax. “I take an expressway every single day to work because I can’t get on Highway 87 because it’s too congested!”
