Counties in the San Francisco Bay area are considering getting rid of gas taxes and switching to a vehicle miles traveled (VMT) system instead. The National Surface Transportation Infrastructure Financing Commission (NSTIFC) recommends the switch because revenue from gas taxes have declined over the years as hybrid, electric, and more fuel efficient vehicles become prevalent on roads. They say that it will “balance the costs and benefits of the surface transportation system to those who are using it”, and could also reduce traffic congestion on the roads. The proposal is one idea in long range planning, updated by the agency every four years. If the idea is accepted, it would likely not be fully imposed until 2020.

Randy Rentschler, a spokesman for the regional commission, admits that the idea could be difficult to introduce. Radical changes like this will always be opposed by certain groups, and privacy issues will be questioned as a GPS based systems would be used to log information on when and where drivers are traveling. Transit advocacy groups are encouraging the transition to a VMT system to be tested first in the Bay area where the idea will be more easily accepted and the revenue could be used to support alternative public transportation options.
