1 Team BIKES ( Bikeshare I ntended K eyless Encrypted S mart-locks) Junior Colloquia 11/20/14 Mentor: Dr. Robert Newcomb Librarian: Ms. Robin Dasler Members: Luke Boegner, Peter Cho, Kyle King, Nicholas Fleming, Tyler Gilman, Eric Huang, Joshua Lafond, Nathaniel Kruder, Tim McLaughlin, Isaac Noh, William Poh, Emily Ruppel, Libby Wei Conclusion

2 Bikeshares are a force for change Relatively new trend Promotes healthy lifestyles and sustainability Capital Bikeshare Washington, D.C. Hubway Bikeshare Boston, MA Conclusion

3 Problems Current bikeshares are not well suited to college campuses Docks are inconvenient for short commutes High cost of bicycles and docking equipment Empty Docks Capital Bikeshare Conclusion

4 Solution: a stationless bikeshare enabled by smartlocks Eliminates docking stations I wanna Simplified implementation process park here! Convenient for travelling needs in college campuses or here! Conclusion

5 How to Use Our System Conclusion

6 Conclusion

29 Budget Breakdown Bicycles Spent $ $ $ $ Future Spending $ $ $ $ Total Spent $ Total Future Spending $ Total Budget $ Conclusion

30 Branding & Pricing Apply to UMD & other college campuses Red Bar Inspiration of Red Bar Logo Conclusion

31 Other College Bikeshares: Station-based Pricing Structure Seasonally/ Monthly/ Yearly/ Daily Numbers: Potential users, number of bikes Bikeshare at University of Michigan, Ann Arbor Conclusion

32 Focus Group (Spring 15) Process of getting IRB Gauge student current understanding of bikeshares Get feedback on web app and lock design(s) Conclusion

33 Conclusion Where we stand: Finishing the prototyping stages : 3D printed lock designs, testing existing locks : Operational code, meeting size constraints : Web app, Zigbee network : Filed for IRB approval, payment and branding scheme

34 Conclusion Long Term Objective: Complete the integration of the system parts to achieve: 2 bicycle system by mid-spring, bicycle system by Fall, 2015 Final objective: Demonstrate a proof-of-concept for a stationless bikeshare on a college campus

35 Conclusion Greatest Challenges: Changing focus while staying true to the project s original goals Mobilizing the team to effectively move forward Individual time management and coordination

36 Conclusion Recommendations: Organization - distribution of power Apply for grants Spend time together
