Freeway and Arterial System of Transportation Dashboard Web-Based Freeway and Arterial Performance Measurement System

This paper introduces the Freeway and Arterial System of Transportation (FAST) dashboard, an integrated web-based freeway and arterial performance monitoring and measurement system. The dashboard provides an intuitive web-based user interface to present real-time and historical freeway and arterial network monitoring and performance information in a variety of displays, including the interactive three-dimensional surface plot tool, which the user selects and customizes. These displays also include most of those found in the Highway Capacity Manual and other widely accepted professional handbooks. In addition to comprehensive performance measures, newly defined measures, such as delay volume in mile-minute(2), are applied in the system. Since September 2009, the FAST dashboard has been widely applied in day-to-day operations, incident management, express lane evaluation, ramp meter operation and evaluation, intelligent transportation system device maintenance, and operation data quality control. Moreover, the system facilitates coordination with other transportation fields by providing information to the planning and transit departments.
