Overview
******************************************************
The software and documentation produced during Project L08 are currently being updated as part of NCHRP 3-115. Updated products will be available in early 2016 at hcm2010.org. After the 2016 release of updated products, Project L08 material contained in the Reliability Archive should not be used.

This document is intended to provide guidance on using the FREEVAL-RL computational engine, which implements the Freeway Reliability Analysis methodology developed in SHRP2 Project L08. FREEVAL-RL is a Microsoft Excel based computational engine coded in the Visual Basic for Applications (VBA) platform. The tool has a Graphical User Interface (GUI) to facilitate data entry and navigation through the tool. The core computational engine of the tool is an enhanced version of FREEVAL-2010, which is the computational engine for the freeway facilities methodology in Chapter 10 of the 2010 Highway Capacity Manual. Some modifications and enhancements to the core computational engine of FREEVAL-2010 have been made to make the tool and method ready for reliability analysis.
