Conclusions

Optimally, all racks would have moderate utilization numbers, and there wouldn’t be too many cases of over-utilization

Racks in high traffic areas are over-used, racks in low traffic areas are rarely used

This tells us two things: Some racks need to be added or repositioned Also, awareness needs to be increased

Recommendations

For the UW campus, GPS may not be the best avenue to reach this project’s goals

the high concentration of buildings on campus, along with PDOP, obstructed satellite coverage

Led to skewed results

Digitizing points, especially with the tablet PC, proved to be more time-efficient and accurate (in our case) than taking GPS readings

Bigger team needed to cover campus in a timely manner

Recommendations: The Next Steps

Network analysis of bike paths/routes on campus

Efficient routes with nearby racks and lockers

Bicyclists travel and storage patterns Analyze the use of racks and lockers for travel storage vs.

overnight storage
