1250 traffic segments covering 300 miles of Chicago's arterial roads are monitored. The Chicago Traffic Tracker estimates congestion in real-time by analyzing GPS traces from Chicago Transit Authority buses, with speeds updated every ten minutes. Data is provided by data.cityofchicago.org and was last updated on 2026-04-03.
Use Cases
- Predict real-time traffic flow using CURRENT_SPEED, STREET, and DIRECTION from 14 available columns.
- Map congestion hotspots by visualizing SEGMENTID, START_LONGITUDE, START_LATITUDE, END_LONGITUDE, and END_LATITUDE.
- Analyze speed volatility over time using CURRENT_SPEED and LAST_UPDATED for specific segments like those on STREET or FROM_STREET to TO_STREET.
- Calculate average segment speed and length correlations using CURRENT_SPEED and LENGTH for route planning.
Strengths
- Covers approximately 1250 segments across 300 miles of principal arterial roads.
- Data is updated every ten minutes from a real-time GPS monitoring system.
- Includes 14 columns with geographic coordinates (START_LATITUDE, START_LONGITUDE), street names, and directional data.
Limitations
- Row count is unknown, which may limit suitability assessment.
- Description notes high volatility in segment speeds, which may affect model stability for individual segments.
- License and author information are unknown.
