OpenTraffic is a free, global traffic speed data set linked to OpenStreetMap built with open source software.
Traffic speed data is a critical input to many transportation related applications. Fortunately many users who need speed data also produce the inputs necessary to create anonymized traffic statistics.
OpenTraffic provides the space and tools to share traffic statistics from connected vehicles and mobile services. We support the development of analysis and routing tools that enable cities, businesses, and individuals to make use of this data.
How it Works
OpenTraffic connects anyone with real-time or archived GPS location data to processing technology, data storage, and routing and analysis applications.
Location data privacy is paramount. We allow contributors to share anonymized traffic speed statistics from derived GPS data without disclosing individuals' location information. In return, data contributors help build a global traffic speed data set that can be used in routing and analysis applications.
The OpenTraffic platform is comprised of several components to make it easy to share and use traffic data:
GPS probe data can be generated from a variety of sources, including mobile applications or fixed GPS hardware. GPS data can be processed in real-time or archived and transmitted for batch analysis. The OpenTraffic platform has a variety of open source tools to help you load your GPS data from existing sources or connect to Amazon AWS Kinesis streams to manage real-time flows of any size.
GPS data is linked to the OpenStreetMap network via Traffic Engine. Data is converted from GPS locations to roadway speed observations and anonymized before being aggregated. As open source software, you control where Traffic Engine is deployed, allowing full control over GPS trace data. Simply install Traffic Engine and load your GPS data to start generating traffic data.
Once anonymized, traffic statistics are added to the global OpenTraffic data pool. By pooling data many different data sources are merged together to provide a seamless global data set, free for use by any application.
We are working with vehicle fleet operators, app developers, and governments to develop and operate the OpenTraffic platform. Learn how you can contribute and benefit:
Do you need traffic data for your application?
Start building applications that utilize the global OpenTraffic data set. Historical and real-time travel speeds enable accurate routing, estimated time of arrival and other transport analysis and planning applications.
Do you collect traffic or location data?
Join our community of data contributors sharing anonymized traffic statistics using Traffic Engine. You'll benefit from combining your data with sources to create a more complete and current data set. In addition to using this data in your own applications you'll be improving the global data pool and help improve transport outcomes in your community.
Do you need traffic data for your city?
Use traffic data to help inform transportation planning decisions in your community. OpenTraffic's analysis applications allows users to query real-time and historical traffic conditions and monitor roadway conditions.
OpenTraffic, forming as a nonprofit organization, is coordinating open source software development and data collection by individuals and organizations across the transport sector.
