Chicago Average Daily Traffic Counts for 2006

Average Daily Traffic (ADT) counts estimate vehicle volumes on Chicago streets for an average weekday in 2006. The dataset includes sample counts along major streets, providing vehicle volume by direction, total volume, and location details. It was published by the City of Chicago's Department of Transportation.

Use Cases

• Model traffic congestion patterns using Total Passing Vehicle Volume and Vehicle Volume By Each Direction of Traffic across different Street segments.
• Analyze traffic density by geographic area using Latitude, Longitude, and associated Community Areas or Zip Codes.
• Assess historical traffic trends for specific locations by correlating Date of Count with Vehicle Volume By Each Direction of Traffic.
• Support infrastructure planning by joining traffic volume data with Census Tracts or Wards for demographic analysis.

Strengths

• Includes precise geospatial coordinates (Latitude, Longitude) for each count location.
• Provides multiple geographic aggregations including Community Areas, Zip Codes, Wards, and Census Tracts.
• Contains directional traffic volume data (Vehicle Volume By Each Direction of Traffic) for detailed analysis.

Limitations

• Data is historical and from a single year (2006), limiting current applicability.
• Sample counts are taken only on larger streets, missing traffic data for smaller residential streets.
• Update frequency is approximately every 10 years, resulting in significant temporal gaps.
