Norfolk Traffic Speed and Volume Studies for Speed Hump Qualification

Norfolk, Virginia traffic engineering studies conducted on city streets. The dataset includes study locations, dates, traffic volumes, vehicle class breakdowns, and percentile speeds to assess eligibility for speed humps or tables. Data is updated ad-hoc as new studies are completed and provided by the Department of Transportation.

Use Cases

• Identify streets qualifying for traffic calming using Speed Limit, 85th Percentile Speed, and Average Daily Volume columns.
• Analyze vehicle composition and its relation to speed using Passenger Car Volume, Large Truck Volume, and Motorcycle Volume columns.
• Model speed distribution patterns using Average Speed, 50th Percentile Speed, and 95th Percentile Speed columns.
• Geolocate study areas for spatial analysis using Street Location, Latitude, and Longitude columns.

Strengths

• Includes detailed speed percentiles (50th, 85th, 95th) and pace speeds for traffic analysis.
• Contains granular vehicle class volumes (e.g., Passenger Car, Bus, Large Truck) from 25 available columns.
• Provides geographic coordinates (Latitude, Longitude) for spatial mapping of study locations.

Limitations

• Row count is unknown, which may limit suitability assessment.
