Induced Demand and Transit
Wednesday, November 28th, 2007There’s an old Catch 22 in public transportation: People won’t ride transit unless it is frequent and convenient. On the other hand, transit providers can’t afford to increase service and frequency unless they have the riders to justify it.
In traffic engineering, the paradigm is different. The typical practice is to build roadways to meet demand in 20 years. This increased capacity induces demand. An example: when North Reserve Street was expanded to 4 lanes, development occurred at an accelerated rate, and the 20-year traffic projections were exceeded in a mere 6 years.
Currently, the Montana Department of Transportation is studying what to do about regional transit greater Missoula area. The consultant recommends a stepped approach to adding transit service: a little here, a little there - as demand increases. This method is inherently short-sighted. A twice-daily bus to and from Lolo is not enough to be convenient, so people won’t use it, and the trigger point for adding more service won’t be reached.
Conversely, ASUM Transportation offers bus service so frequent that you don’t even need a schedule, and their ridership is through the roof. Buses have standing-room only. In less than ten years, ridership has increased from under 4,000 rides per year to over 300,000. (That’s about a 7400% increase.)
While 10-minute service from the Bitterroot is a little excessive, the consultant and the state need to keep in mind this old idea: that if you build it, they will come!
A public meeting regarding the plan will be held on December 5th from 4:00 to 6:00 at the Grant Creek Inn in Missoula.
