A transit agency in Silicon Valley has set up six cameras to count how many buses carrying Apple and Google and other tech employees are using its roads.
Officials with the Santa Clara Valley Transportation Authority officials say the companies have been unwilling to share information about their shuttle buses.
The San Francisco Chronicle reports Thursday that the agency is examining the impact of corporate bus fleets on traffic as it analyses ways to improve vehicle flow on Highway 85.
The agency estimates that tech companies spend roughly $249,000 a year to operate each shuttle, with an annual cost per rider of $12,000 to $15,000.
The double-decker buses are ubiquitous in the San Francisco Bay Area and have become a symbol of gentrification.
