Updating and Implementing the Grade Severity Rating System for Wyoming Mountain Passes, Phase 2

This project is set up to validate the grade severity rating system (GSRS) model for trucks that have one drum brake installed, make the GSRS fully implementable, and to develop a program that simplifies the implementation of the GSRS and formulation of weight specific speed signs. The project shall validate the GSRS model for trucks fitted with only drum brakes; incorporate curves into WSS sign formulation; develop a program to automate formation of WSS signs; and update the GSRS user manual.
