Design 03-11.pdfDesign 03-1111/2/201111/2/2011Traffic Engineering Analysis
The attached Traffic Engineering Analysis document provides guidance for the Project Development Team (PDT) and design engineers on the use of traffic engineering principles and procedures when designing a
highway project. Effective with this memorandum, the attached guidance should be used when the PDT deems that their project warrants such traffic analysis. While these guidelines can be applied to any project, the PDT should utilize them when the project purpose and need statement identifies the need for operational and/or capacity improvements.
