12th Ave S Bicycle Traffic Counts from Inductive Loop Sensors

Inductive loops on the east and west bicycle pathways of the 12th Ave S bridge count passing bicycles regardless of travel direction. The City of Seattle maintains this counter, which came into service early 2025 and was last updated in March 2026. The data likely provides a time-series record of bicycle traffic crossing the bridge.

Use Cases

• Model daily and seasonal bicycle traffic patterns based on continuous inductive loop counts.
• Assess bicycle infrastructure demand and usage on the 12th Ave S bridge.
• Compare eastbound and westbound bicycle flows based on separate pathway sensors.
• Integrate bicycle counts with other urban mobility datasets for multimodal analysis.

Strengths

• Data is sourced from physical inductive loop sensors, providing objective counts.
• Records are updated frequently, with a last update timestamp of 2026-03 15.
• Counts bicycles on both east and west pathways separately, allowing for directional analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The description metadata is limited; actual data quality requires manual inspection.
