PRE-PUBLICATION DRAFT -- Unedited Text and Graphics Project Delivery Considerations for ATM Construction and implementation for ATM can involve building and installing specific ATM components on an established facility, such as a freeway or arterial, or implementing ATM elements as part of a larger construction or facility expansion/rehabilitation effort. In the latter scenario where the ATM components are integrated into a larger civil engineering construction package, agency staff responsible for the ATM elements may need to play a larger role as part of the overall construction coordination and project management effort to help align technology infrastructure procurement, systems procurement, and system testing and integration activities within the broader project schedule (Kuhn et al.

PRE-PUBLICATION DRAFT -- Unedited Text and Graphics document highlights the key systems engineering steps, including the development of the Concept of Operations and Requirements, which outlines the core planning and design steps to define ATM software needs and capabilities. Engaging the right stakeholders in these processes will help ensure that multiple perspectives on software and system needs, functions, and capabilities are captured prior to embarking on an implementation effort.

PRE-PUBLICATION DRAFT -- Unedited Text and Graphics Schedule Considerations Schedules are critical on any project, but ATM projects involve a complexity of coordination that increases the criticality of the schedule for an effective delivery. A traditional freeway-focused ITS project can experience a delay with minimal or no impact on the day-to-day operations of the facility.
