The Optimal Traffic Monitoring project is intended to raise the awareness of viable traffic data sources that have emerged over the past decade.  This new age of data and communications has opened up new avenues for traffic monitoring.  The intent of this paper is to outline how to leverage these new data sources in combination with traditional data resources for the best results.   The target audience for this document is engineers, planners, and managers at state, county, metropolitan planning organizations (MPOs), and cities involved in transportation planning and operations.  The full report can be found here.

Many agencies are re-examining how best to architect their traffic monitoring and management systems using multiple data sources, types and levels of fidelity, the design of a monitoring system is becoming requirements driven. Some of the data sources being used today are outlined below. A one-page document is available here.
