Urban bike‑share programs generate massive streams of geospatial, temporal, and demographic data that are ideal for exploratory visual analytics. This project designs, implements, and evaluates an interactive dashboard that visualizes real‑time bike‑share activity for the city of Portland, Oregon. Using the public GBFS (General Bikeshare Feed Specification) API, data were harvested every 30 seconds for a 30‑day period (≈ 1.3 M records). After cleaning, the dataset was enriched with weather, transit, and census tract information. The 837 (Professional, Institutional, or Dental) is used

Four visualization modules were created in Tableau 2024.3 and Python (Plotly‑Dash):

A mixed‑methods evaluation (heuristic inspection, SUS questionnaire, and a 30‑minute think‑aloud session with 12 city planners) demonstrated a System Usability Score of 84.5, a statistically significant increase (p < 0.01) in insight generation speed compared with the legacy static reports, and strong support for equity‑focused decision‑making. Key features:

The dashboard is publicly hosted on Heroku (URL: https://havd837‑bike‑dashboard.herokuapp.com) and the full source code is available under an MIT licence on GitHub. Recommendations for scaling the system to city‑wide deployment and for integrating predictive demand modelling are discussed.


Our design follows Munzner’s “Visualization Design Process” (2014) – a six‑stage pipeline that ensures analytic goals drive visual encodings.
