Jarrett Walker Comes to Tucson

Though the origins of the phrase “Think globally, act locally” are disputed,  and it has been used in so many different contexts it sometimes seems like a cliché, in regard to an issue like climate change, it’s very apropos. Climate change affects our whole world, but anything I can do about it has to start where I live right now.

So in the past two weeks, on the “think globally” side of things, I signed up for a MOOC called “Climate Change in Four Dimensions,” which is an eight-week course from UC San Diego.  The course views climate change from the point of view of natural sciences, technology, social sciences, and humanities -- the four dimensions cited in the title -- and so far lectures have addressed the history of climate change science and the scientific consensus on climate change.

On the “act locally” side of things, there’s actually a lot going on in Tucson right now, especially in relation to public transit. On Wednesday evening I attended the Bus Riders Union monthly meeting where I spent time with 25 dedicated and energetic supporters of the bus system here in Tucson. We talked about the fact that our so-called modern streetcar will begin running on July 25, and though Bus Riders Union members do plan to use the streetcar, they also want people to remember that the group has as one of its five goals: Keep bus dollars on the buses -- do not use bus funds for streetcar expenses. The streetcar, which has as its end points the University of Arizona campus and downtown Tucson, is an important adjunct to public transit in our city, but buses are the main people movers in the SunTran system.

Then on Friday evening I attended a presentation by Jarrett Walker, whose appearance in Tucson was sponsored by a range of groups from Bus Riders Union to the City of Tucson Department of Transportation. Walker  is a consultant on transit network design and policy and is also a blogger whose take on the event can be found at http://www.humantransit.org/2014/07/tucson-a-frequent-network-map.html. Walker rarely mentioned green aspects of using transit but focused on the factors that encourage people to ride buses and trains. At the beginning of the talk, he said that everything is changing and there is no status quo any more. He went on to talk about the VMT inflection point and the changing role of cars here in the U.S. (VMT is jargon for vehicular miles traveled, a number which rose steadily between the end of World War II and the mid-2000s and then leveled off -- see “The Case forModerate Growth in Vehicle Miles of Travel: a Critical Juncture in U.S. TravelBehavior Trends.”) 

Walker also said that “the market wants transit-friendly places.” Many people, especially young people, want to live in places where they don’t need cars. They are concerned about the environment, and they want diverse and affordable urban neighborhoods, the type of neighborhoods transit facilitates. Walker also cautioned against binary thinking – for example, it’s wrong to think that some people are “choice riders” and some people  are “captive riders” or that some people want only to ride trains and others buses. He showed us a map of the small but functional high-speed grid here in Tucson where people can travel without having to wait for more than fifteen minutes. He reminded us that some people will choose to live in areas well-served by transit, including low-income people. But low-income people's choices are important. In fact people in the Bus Riders Union who chose a transit-centered lifestyle are pioneers. Hopefully, more people will soon follow their lead.
