NYC Crash Tracker

In summer 2024, I collaborated with Transpo Maps to design an interactive visualization that tracks vehicle crashes in New York City’s congestion pricing zone (CPZ). The project raised awareness of the human cost of Governor Kathy Hochul’s decision to delay congestion pricing—a policy expected to reduce traffic below 60th Street by 17%, removing 120,000 vehicles daily.

The final product transformed raw data into a visually compelling advocacy tool, supporting efforts to protect vulnerable New Yorkers. The project received notable media coverage, including a feature in Streetsblog NYC, which praised the map for illustrating the human toll of traffic crashes and reinforcing the urgency of implementing congestion pricing.

Led by Stephen Braitsch, who provided the concept, creative direction, and engineering, the project was a collaborative effort that combined visual design, messaging, and technical expertise. I was responsible for developing a cohesive and engaging user interface that aligned with Transpo Maps’ brand style while reflecting the gravity of the issue and pushing visual boundaries for maximum impact.

My contributions included refining key elements such as the interactive map, sidebar, and daily crash counter. I ensured the map, which updated daily using NYC’s open data portal, allowed users to explore crash details and local demographics.

To enhance usability, I implemented a tab switcher to separate crash and demographic data, designed animated data bars for clear visualization, and recommended features like preventing unintentional map zooming and visually highlighting the current day on the time-series chart. Beaudry Kock developed the messaging strategy, ensuring the project’s narrative effectively communicated the urgency of the issue.

The collaboration resulted in a data-driven storytelling platform that connected users to the real-world impact of policy decisions. By making complex data accessible and emotionally resonant, the project amplified public discourse on the need for congestion pricing and positioned Transpo Maps as a key player in using design and data to advocate for safer, more equitable streets.
