The Grade Severity Rating System (GSRS) is a computerized procedure using downgrade geometrics to determine the appropriate maximum safe descent speeds for large trucks on steep downgrades. The purpose of the GSRS is to reduce the probability of large truck runaways on steep downgrades. It is based on a model that uses gross truck weight and the physical characteristics of the downgrade to predict the truck system's brake temperature. The brake temperature estimates are used to determine maximum safe descent speeds for various categories of truck weights. The maximum safe descent speed information is presented to the truck drivers by weight specific speed signs installed on the downgrade. In addition to determining the maximum safe descent speeds for trucks, the procedure may be used to establish truck downhill speed limits, establish the need for and location of truck escape ramps, and analyze truck accidents. Software Description: The software is written in the Basic programming language for implementation on an IBM PC or compatible microcomputer using MS DOS 3.0 or higher operating system. Additional requirements in hardware are a 132 column printer.
