President Barack Obama's May 1 commencement visit will complicate the traffic congestion typical of a University of Michigan graduation weekend.

And two college students hope to offer a way around it all.

On graduation weekend, Calvin Schemanski, a University of Michigan business sophomore, will team up with a friend and forgo end-of-the-year parties to cash in on the festivities surrounding graduation and the presidential visit to Michigan Stadium.

Schemanski started the pedicab business in Petoskey last summer with his friend Josh Lycka, a Grand Valley State University sophomore. The Petoskey natives ended up making back their initial investment in equipment and making some cash in their hometown, while building up a lot of endurance hauling people around in hilly Petoskey.

"It was really successful at night with bar crawls," Schemanski said of business in his hometown. "I thought it might be a great idea to bring it to Ann Arbor."

From Friday, April 30 through Sunday, May 2, the two will provide pedal-powered taxi service around Ann Arbor. AA Pedicab (an offshoot of Petoskey Pedicab LLC) will offer tip-based rides from early afternoon to late into the night, Schemanski said.

Now, they're looking for sponsorship opportunities from local Ann Arbor businesses to advertise on their cabs, shirts and hats that weekend in order to keep rides free to pedestrians. Meanwhile, U-M is sounding early traffic congestion warnings leading up to the 11 a.m. event at Michigan Stadium, promoting shuttle use and detailing what is known about road closings so far.

Here is what residents can expect:

Getting around on May 1

• Traffic congestion on all routes into Ann Arbor and to the stadium can be expected. Some streets could be blocked entirely that morning, so drivers should plan routes with alternatives in mind. • If traffic is re-routed to accommodate arrival of the president’s motorcade, police will instruct drivers about alternate routes. The only known closing at this time is Main Street between Pauline and Stadium Boulevard. Vehicle access on Keech and Greene streets will be restricted due to shuttle bus traffic.

• Shuttle services will be available to and from select hotels, central downtown locations, and some university parking lots, running every 20 minutes from 5:30 a.m. on.

• Several roads and parking lots near the stadium will not be available for use due to enhanced security.
