Systems Engineering Projects

Athey Creek supported the Minnesota Department of Transportation in developing model systems engineering documents for six ITS applications (dynamic message signs, video, traffic detection, communications/radio, flood warning, and ramp metering). Each document describes the system and components; includes a concept of operations, system requirements and test plan; and outlines CAV infrastructure systems to facilitate CAV infrastructure readiness. Each document also describes the relationship of the application to the National ARC-IT and Minnesota ITS Architecture.

Athey Creek led development of a concept of operations and implementation roadmap as well as internal stakeholder engagement to support the Minnesota Department of Transportation’s efforts to achieve their vision for work zone data. These efforts sought to provide automated vehicle-ready work zone data for all lane closures caused by maintenance and construction work zones through a series of activities, including automated reports from field devices and fleet vehicles and implementing the work zone data exchange specification. Athey Creek also completed the system engineering documents for three automated warning systems: ice warning, fog warning, and curve warning. In addition, Athey Creek supported development of a holistic vision and systems engineering document for work zones in Minnesota including work zone data assembly, processing, and dissemination as well as targeting operational concepts for work zone data to support and be supported by connected and automated vehicles.

Athey Creek supported the Utah Department of Transportation (UDOT) in defining the needs and requirements for a new advanced ATMS and ATIS and developing the procurement documents for both systems. The key focus of the new ATMS was on integration with legacy systems while being able to utilize state of the art software and incorporate emerging technologies as they are deployed. Athey Creek led development of system requirements for traveler information software to integrate with UDOT’s data sources while providing the public with information through streamlined web, phone, and mobile applications. Athey Creek also supported the demonstration of existing products and the development of systems engineering documentation, including a concept of operations, system requirements, and a request for proposals.

Athey Creek is a member on the team developing the National ADS Integration Concept of Operations (previously the Highway Automation Concept of Operations) document to present a shared future vision of how ADS can safely, equitably, and efficiently be integrated with the overall transportation system. This project aims to identify how ADS technology could manifest on public roads, as well as the interactions between physical, digital, operational layers of the transportation system and ADS-equipped vehicles. As part of this effort, Athey Creek led stakeholder engagement efforts that included a national dialog with public- and private-sector ADS stakeholders and individual “Beta Site” walkthroughs with multiple agencies in 16 states to capture input to early draft content for the concept of operations.
