Visualizing Bike-Lane Obstructions

Bike Bureau reports can be shown at several scales. These are the main visualization formats, ordered newest to oldest.

The live accumulation

August 2026 · interactive timeline

Each report is sorted by timestamp and added to the map at its recorded coordinates. Vehicle cutouts are separated with a repulsion solver so dense locations remain readable; the map and count stay tied to the underlying report set.

The controls scrub or play through the reporting period. The current build uses the August 2026 Boston-area report data and vehicle cutouts.

The traffic snake

August 2026 · physical scale comparison

Four hundred seventy-nine public-safe reports were represented as vehicle-length units and routed along real streets around the Charles River. The result is 2.8 kilometers of reported obstructions as a single visual measure.

The citywide accumulation map

July 2026 · chronological map

Five hundred seventy public-safe reports in the Boston-area viewport were placed by location and revealed in timestamp order. The still shows the final spatial distribution; the animation shows the rate and geography of accumulation.

Block-level hotspot reconstructions

June–July 2026 · repeated-location evidence

At smaller scales, report images are placed along the visible roadway or bike lane and labeled by time. These views isolate repeated activity at a loading zone or intersection and can combine Bike Bureau and public 311 records while keeping the sources distinct.

The common fields are report timestamp, coordinates, source image, and privacy treatment. The layouts change; the records do not.
