With an estimated reduction of over 45 million vehicle miles traveled per year, a big benefit of the private shuttle buses running from San Francisco to the Peninsula is a reduction in overall vehicle emissions and congestion on the roads.
According to an analysis conducted by the Department of Public Work’s Infrastructure Design & Construction Division, however, the cost impact that a large shuttle bus has on the lifetime of the physical roadway is nearly 4,700 times that of an individual SUV:
…every time a large shuttle bus drives over [a] hypothetical lane mile, the impact on the pavement accounts for $1.08 out of the $1,045,000 it will ultimately cost to reconstruct the lane. In comparison, the cost impact that a typical passenger vehicle has on the lifetime of pavement is $0.00023 every time it drives on the same hypothetical one-mile long lane mile.
On the agenda for San Francisco’s Board of Supervisors this afternoon, an environmental appeal of the SFMTA’s approved pilot program which would allow private shuttle buses to share the use of San Francisco’s municipal bus stops for a fee of $1.06 per stop.
The fee is designed to simply capture the cost of administering the pilot program but does not capture any additional impact to the roads, as the “SFMTA is precluded from charging a fee for the proportional cost of such damage pursuant to Section 9400.8 of the California Vehicle Code, which restricts the ability of a local jurisdiction to impose a tax, permit or fee for use of City streets.”
