Researchers tell us one way to stay trim is to walk more often.

But that’s hard in some neighborhoods – maybe sidewalks are bad or there are no stores to walk to.

Shawn Allee found one researcher who thinks what really stops us … is actually in our heads.

Dr. Tanya Berry researches physical activity, and she surveyed people living in Edmonton, Canada.

She calculated how trim or fat they were, then she logged details about their neighborhoods, things like how many stores are nearby and how many cars pass through the area.
Berry says the thing that mattered most, and kept people from walking was a subjective feeling that there are too many cars on the street.

“There was too much traffic in their neighborhoods, it made it difficult to walk, so they chose to jump in their cars and contribute to the traffic problem.”

Berry says her research team will look at how buildings and streets can be designed to make pedestrians feel there’s less traffic than there actually is, and maybe feel more comfortable walking down the street.

Pedaling While Reclining

Bicycles are about as green as you can
get. They’re economical and provide great
exercise. But a lot of people draw the line
at hunching over those skinny, hard seats.
There are bikes that offer more ways to ride,
whatever your age or size. Lucy Martin reports:

“This pump gets used a lot, so sometimes it doesn’t want to stay on.”

(Sound of employee operating tire pump)

The air pump beats the gas pump every time. Bikes are pretty simple to use. No gas, no bus fare.
Check the tires and you’re good to go.

(Sound of blast of tire pump air)

A lot of people who don’t bike now wish they could too. And that’s where recumbent bikes can help.

(sound of entry bell chimes, door opens and closes)

“A recumbent is a bike where you sit down with your feet out in front of you and it’s comfortable like
your office chair. It’s comfortable like the chair you watch TV in. It puts you in a seated position like
the car you drive.”

That’s Peter Stull. Nearly 30 years ago he took a one-room school house and turned it into a business
called The Bicycle Man. The small store in Western New York has become a magnet for shoppers
interested in bikes that feel good.

Employee: “Where you guys coming from?”

Customer: “Ottawa, Canada.”

Employee: “Yeah? Locals.”

People regularly travel long distances to check out the extra-large selection.

“We have a couple kinds of customers. And one is the customer who is a serious road-bike geek for
decades and he just got a report, from the doctor, saying ‘you can’t’ because of wrist, neck, prostate –
something – you can’t ride anymore. Or, maybe runner, can’t run anymore. And they really want to
stay active. They come to us.”

Stull sees plenty of brand-new bikers too. They come in every age and shape. His motto is ‘Ride before
you decide’, because there are so many variables to consider.

“You know, if you look at a racing bike, you give up everything for speed. But did you want speed? Or
comfort? Or Durability? Or foldability? Or – would you like me to show you the compromises on our
design?”

Stull spends a lot of time testing and tinkering in the shop out back. He’s on a quest to build even better
bikes. No single style can do everything for everyone. But Stull says recumbents can solve a number
of common problems.

“If you’re uncomfortable–like have a pain issue on a traditional bicycle? This will probably eliminate
it. If it’s a hip or a knee issue, maybe it won’t help. If it’s a balance issue, then maybe a trike recumbent,
with three wheels.”

I had to try the cool trike bikes. I wasn’t sure what to expect. They were amazing. Really low and super
fast. But they need a lot of room to turn. Stull says trike bikes give some of his physically challenged
customers the bike freedom the rest of us take for granted.

(Sound of Stull greeting customers)

Saturdays get busy. I asked John and Deb Wegman why they bothered to drive 90 minutes from
Rochester.

John Wegman: “My wife. (laughter) Yeah. That’s it! Exactly!”

Deb Wegman: “Be honest.”

John Wegman: “Well, we wanted to try them because they’re supposed to be very comfortable and a
different kind of ride. And this is the place to come, because you can’t find them anywhere else. All
the other bike shops have maybe one. And you can test drive it in the parking lot for a hundred yards,
maybe.”

Lucy Martin: “And you’re about to go out on a ride of as long as you want?”

John Wegman: “Right. And we can come back and try another one, and do it again, if we want to.”

Recumbents are hard to find. They can cost a bit more too. But Stull says any good bike that’s cared
for should last for years.

(Sound of a car whooshing past.)

After maybe 20 minutes, John and Deb come back.

John Wegman: “That was a lot of fun – a very comfortable ride.”

Deb Wegman: “It was great! Yeah, I’m actually going to have them change the seat, on that one ’cause
I’m interested in the wider seat.”

Lucy Martin: “Try that bigger seat?”

Deb Wegman: “Yeah.”

The Bicycle Man carries basic recumbents all the way to slick racers. They sell regular bikes too.
Whatever buyers chose, Peter Stull recommends taking enough time to find the right bike for each
body. He says comfortable bikes get ridden. The rest just sit around and rust.

Recumbent bikes are beginning to catch on across the nation. But, active baby-boomers might just
make bicycle shops think about peddling more of them.

The High Costs of Empty Parking Lots (Part Ii)

  • A new book says that much of the space covered by parking lots is only designed for use for the holiday rush, and is unused for the rest of the year. (Photo by Lars Sundström)

A growing number of city planners say we’re building more parking than we really need. They say the fact that nearly all parking is free, makes the situation worse. Their ideas are turning nearly fifty years of urban planning on its head. The Great Lakes Radio Consortium’s Shawn Allee has this second report in a two-part series:

A growing number of city planners say we’re building more parking than we really need. They say the fact that nearly all parking is free, makes the situation worse. Their ideas are turning nearly fifty years of urban planning on its head. The Great Lakes Radio Consortium’s Shawn Allee has this report:


If you had to pay for a parking space, would you think twice before making a frivolous trip, say, to a convenience store for a candy bar?


City planning researcher Donald Shoup bets you would stay home if you had to pay, or maybe you’d walk instead. That’s a point he makes in his recent book, The High Cost of Free Parking. In it, he tries to show that free parking entices us to waste gas. He says paved lots also compete for better uses of land, like parks or housing. Shoup says the problem’s very real – but to see it, you need to step out of your automobile.


“Any view of suburbia from the air will show you a lot of parking lots and a lot of these parking lots will have empty parking spaces.”


I decided to take a look at what’s Shoup’s talking about in Lincolnwood Illinois, a Chicago suburb. I cheated by skipping the air fare, though. Some new Internet sites can provide satellite photos of your area. I joined two of Lincolnwood’s city planners, Tim Clarke and John Lebeque, in their office to get a birds-eye view of their home turf.


Clarke: “The plus is closer.”


Allee: “Right, and go ahead and see if you can find… There it is. Lincolnwood.”


Clarke: “Wow.”


Lebeque: “Whoa.”


Allee: “So find a retail strip.”


Turns out, Donald Shoup was right. Within a minute, we find a popular grocery store, with a huge parking lot. Tim Clarke recognizes it.


“It’s probably one-third filled. I’m not sure when this aerial was taken. I’ve never seen the parking lot full.”


So why should a busy store’s parking lot be two-thirds empty most of the time? Shoup says it’s the cities’ fault. Cities make the rules. They say how many spaces each new business, house, and apartment building must provide.


By his estimation, city government does a poor job at guessing how much parking we really need. Shoup says governments force businesses to provide enough spaces to meet peak demand, such as the day after Thanksgiving, the busiest shopping day of the year.


“Everyone understands the advice, don’t build your church for Easter Sunday, but we build our parking for the week before Christmas.”


In other words, cities tell stores to build parking for the year’s busiest two weeks, even if most of the spaces are empty the rest of the time. He says, without city pressure, a lot of businesses would create smaller lots or they’d sell off parking space they don’t need.


Tim Clarke, the Lincolnwood planner, says suburbs do err on the side of too much parking, but they’re often planning for future growth. He gives an example of a small Lincolnwood dental practice that had 7 examination rooms, but only used three of them. The dentist wanted to build fewer parking spaces than the village required, because it was small and family-run.


“But one could imagine that that family at some time in life would sell that business and someone would come in and want to use all 6 or 7 examining rooms at one time.”


So city planners have to look at the long term use of a building.


Many of Lincolnwood’s largest retailers actually build more than they need to. Bob Johnson runs a Lowe’s Home Improvement store built in late 2003. He says stores like his don’t gamble with having too few spaces.


“I think customers are going to shop, again, where they feel most comfortable and what’s convenient for them. The key word there being convenience. If they’re inconvenienced, they might drive another couple blocks down the road.”


Shoup says that’s a calculation that businesses have to make. He says market forces can help decide how many spaces should be built, but government should not force retailers to have too many spaces. Nor should it force them to offer only free parking.


In fact, Professor Shoup says cities, especially suburban cities, could use land more efficiently if businesses controlled demand for parking like they control everything else: by setting the right price.


“I’m just saying that cities should not force anyone to provide more parking than drivers are willing to pay for.”


Killing our appetite for cheap, abundant parking could be difficult, but Shoup says pressure’s building for change. He says, as suburbs grow, space gets tight. And that raises prices for all land uses.


“I think most people now are focused on the high cost of housing. I think we’ve got our priorities wrong if housing is expensive and the parking is free.”


In his battle against too much parking, Shoup says the most effective weapon might be a little comparison shopping. Free parking might not seem so cheap once it’s compared to the cost of other needs.
