Standard work zone equipment is integrated with the ATMS system through several efforts including speed management (Variable Speed Limits (VSL) for both dynamic and static displays of speed limit), ramp metering (a pilot deployment within a work zone that can deploy both static and dynamic ramp metering), and traveler information (work zone travel time, use field detectors and/or probe data to provide queue related messaging, and Integrated Corridor Management).
Data Integration
Combined Situational Data Sources to Delineate When Incidents Truly Occurred
PennDOT had a need for better data aggregation and analysis to support decision making. In 2015, PennDOT started an initiative to audit the readily available DOT and vendor data resources that related to Transportation Systems Management and Operations (TSMO). PennDOT combined situational data sources to more accurately delineate when incidents truly occurred, how long it took them to be cleared, and what their overall impact on traffic was.
Integrated Construction Projects into the Traffic Information Website
ODOT developed OKTraffic.org for all traffic related information including the base map layer, Google and Waze traffic data, National Oceanic and Atmospheric Administration (NOAA) weather data, web cameras, Dynamic Message Signs (DMS), and sensor cameras. Integrated construction projects provide the exact project location for construction projects and better inform travelers of expected slowdowns, changing traffic conditions, and construction zones.
Real-Time Arrow Board Status Information
In 2018, MnDOT conducted a one year pilot project through a contract with a vendor (Street Smart) that installed a monitoring device on 20 arrow boards that provided arrow board status information (e.g., right arrow on, left arrow on) to the vendor’s server. The arrow board status information from the server was then integrated with MnDOT’s Advanced Traffic Management System (ATMS) and then their Road Condition Reporting System (RCRS).
Real-Time Arrow Board Status Information
In 2019, the Iowa DOT had access to 5 equipped arrow boards with reporting capabilities (Street Smart, iCone, Ver-Mac) to provide real-time arrow board status information to the vendor’s server.
Waze Reports Added as a Layer on the Iowa DOT 511 Website
Waze reports on Iowa DOT’s traveler information website are labeled as citizen updates, reported by Waze, on their own layer and in the map legend. Waze has been a valuable resource to Iowa DOT for both traveler information and operations in more populated areas, but may not be as valuable in less populated areas with fewer Waze reports.
