Taxi Heat Map NYC Problem & Motivation Cuts and changes to bus routes and schedules have complicated effects on quality of bus service across large areas and on bus delays and road congestion. It is useful to leverage historical data to demonstrate how congestion and coverage changed as the result of route changes. This could help inform future transit policy decisions.

It would be like Sunday schedule, but every day” Seattle bus driver, route 31 Dots on the Bus: San Francisco Design Inspiration & Initial Prototypes • Approach • Focus on Feb 2012 transit change • Data from several pre-/post-change days • Two maps enable comparison for different days/times of day • Colored dots represent locations and delays of buses • User Study • Semi-structured interviews • 8 participants (4 male, 4 female; including Seattle transit experts & transit users) • Feedback on prototype: • Relevance • Interactive features • Color choices • General usability • Desired functionality • Design Improvements • Default to “day” view • Make maps bigger • Do not require click to stet time • Ability to sync maps & times • Add legend • Day selection by day of week • Future Directions • More complete data collection • Animation to show movement during time intervals • Filter by route • Show bus frequencies • “Bus score” metrics • Show multi-day averages CSE 512 Final Project https://github.com/CSE512-14W/fp-cobbc12-cbonnar-pany5-kuksenok http://homes.cs.washington.edu/~cbonnar/viz/ibusviz.html Will Upcoming Transit Cuts Affect You?
