Accessing current, reliable, and relevant data is critical to planners and decision makers. As the region's MPO, DVRPC provides access to a wealth of data, some original to the Commission and some provided by our partners.

Aerial Imagery

Aerial imagery is an essential tool for planning and analysis, presenting a comprehensive view of regional conditions. Having access to aerial imagery from various years provides the user with a chronological record of land use patterns. Aerials have been an important component of DVRPC's planning efforts for many years, with historical aerials available from as early as 1959.


Delaware Valley Data is our periodic series of free data products. Regional Data Bulletins provide the most current data sets for a 28-county extended area, and Analytical Data Reports provide more detailed analyses for DVRPC's nine counties. Data Reference Guides, issued only occasionally, explain how to use specific data sets. Data Snapshots are designed to provide a more in-depth look at specific demographics or topical areas through a series of related snapshots.

Travel Monitoring Counts

DVRPC collects traffic volume counts at over 5,000 locations each year. The data is collected by the pneumatic tubes you see laying across the road. DVRPC also obtains traffic data collected by other entities and includes that data in its database as a public service.

GIS Data

A Geographic Information System (GIS) is an important planning tool that supports state, regional, county, and local planning and technical efforts. Nearly all projects incorporate GIS technology, whether it is for data collection and storage, or analysis and presentation. GIS allows planners to view and query spatial data, perform advanced analysis to discover relationships, patterns, and trends, and effectively present information to decision-makers and the public.

Regional Indicators

Regional indicators are a means to monitor and evaluate implementation of Long-Range Plan goals and determine if the recommendations are being accomplished. Over 30 indicators are tracked, grouped under the four core principles of the Long-Range Plan. The online Tracking Progress indicators are updated periodically.

Survey Data

DVRPC occasional conducts surveys on various topics to better inform regional planners and decision-makers. This includes the Commission’s Household Travel Survey (HTS). The HTS is conducted approximately once every 10 years to help DVRPC better understand the region’s travel characteristics and guide future transportation projects.
