The speeds of 4,258 trucks were measured on downgrades along rural freeways and expressways in California during 1982, 1983, 1984, 1985, 1986 and 1987. The speeds of trucks were measured at eleven grades with lengths ranging from about 1.4 miles to 11.8 miles and average rates of downgrade ranging from about 3.5 percent to 7.1 percent. The results did not provide any definite relationships between truck speeds and rate of downgrade from which downgrade truck speeds can be obtained for any given situation. Each location has its unique set of characteristics which might influence truck speeds on downgrades. Therefore, the information in the report would be helpful for planning and designing freeways at areas where there will be downgrades with similar characteristics.
