Bike To Work Days have a positive correlation with cycling rate

Today is Winter Bike To Work Day in Chicago at Federal Plaza. If the results below are true, we should hold this event weekly during the winter! Held on January 20th to celebrate the coldest temperature on record, in 1985.

I was looking for research on why more people don’t ride bikes, or why they don’t ride bikes more often. I started my search on Professor John Pucher’s website at Rutgers University and found this about Bike To Work Days and other promotional events.

There is some evidence that BWDs increase bicycling beyond the event. The number of “first time riders” has increased in many programs: in Seattle, from 845 new commuters in 2004 to 2474 in 2008; in Portland, from 433 in 2002 to 2869 in 2008 (LAB, 2008). In San Francisco in 2008, bicycle counts at a central point were 100% higher on BWD and 25.4% higher several weeks later; bicycle share was 48.3% before BWD, 64.1% on BWD, and 51.8% afterwards (LAB, 2008). In Victoria, Australia, 27% of first time riders on BWD were still bicycling to work 5 months later (Rose and Marfurt, 2007).

Here’s me surveying an attendee at the 2009 Bike To Work Day Rally in Chicago’s Daley Plaza. The results of the surveys taken each year by the Chicago Department of Transportation are not published.

Road pricing is more fair than other funding schemes

I’ve written several papers on congestion and road pricing*. The most common type seen in the United States is HOT (high occupancy tolling) lanes. This is where drivers can pay to use uncongested lanes; drivers who carpool may use the lane for free or at a discount. Transit buses can always use the lane for free.

From the University of California Transportation Center comes new research on paying for roads with congestion versus paying for roads with sales taxes and their respective burden on poor residents.

Will research show that more people will benefit from paying sales tax to support a transit system than from paying (all kinds of) taxes to support a highway?

Their finding is that funding transportation with sales tax is less fair than funding with congestion pricing. In the latest issue of Access, Lisa Schweitzer and Brian Taylor write:

This analysis has focused on one side of the ledger: the question of who pays. But transportation systems have both costs and benefits. Indeed, the access benefits of travel are transportation’s raison d’être. So while regressivity can be viewed as a cost of road pricing (and of most other ways of paying for roads), pricing confers transportation benefits that other transportation finance mechanisms do not. Tolls and taxes can both pay to build a road. But congestion pricing can also reduce traffic delays, fuel consumption, and vehicle emissions, often to a surprising degree. Sales tax finance for transportation, by comparison, does none of these things.

I think the appropriate direction of this research should next discuss and examine the fairness of using sales taxes to provide operational and capital funding for transit. In Chicagoland, the Regional Transportation Authority is partially supported by a local sales tax. While sales tax financing for road building may not reduce traffic delays, fuel consumption, or vehicle emissions, supporting a reliable, robust and expansive transit network can do all of those things by reducing the number of single occupant vehicles on the road.

*Here’s one I’ve written: Implementing value pricing on a highway in Southern California, which I excerpted in HOT lanes and equity.
