Part 3 - Identify Project Need and Project Initiation Document

II. Project Initiation Document

A. Define Transportation Need and Assess Site (150.05) - Obtain and Review Existing Reports, Studies and Mapping (150.05.05)

P22. Obtain Traffic Concept Report

Offices, such as the Traffic Operations Branch or the Traffic Investigations Branch, within the Division of Maintenance and Traffic Operations, typically generate Traffic Concept Reports. The basis for a Concept Report may be TASAS Table C reports and/or HT65 traffic investigations. The Concept Report may be one or two pages in length and provide basic background information. It identifies the deficiency that triggered the traffic study, the proposed improvement and a rough cost estimate. Concept Reports are also used to identify safety improvement needs such as; signals, lighting, barriers, curve corrections, signing, etc.

Concept Reports are not formal PID reports as contained in the PDPM Chapter 9. The Concept Report, rather, is used to start the project initiation process. Concept Reports are provided to Program and Project Management for the purpose of initiation of a capital project such as a Minor project or a SHOPP operation and safety improvement project. The project engineer should obtain the Concept Report when one is available.
