ROADWAY DESIGN SYSTEM USER MANUAL

The FHWA Roadway Design System commonly referred to as "RDS" is one large integrated computer program which assists engineers in the design of highways. RDS contains over 350 integrated computer subroutines written in FORTRAN IV and four assembler language subroutines. RDS can be used in preliminary route location, design, and final design phases of highway engineering. It contains a comprehensive general bridge geometry process which allows the engineer to perform preliminary bridge designs. This user's manual begins with an overview of the system. Chapter II, "General Information and Design Terminology," defines pertinent roadway shape and geometry terminology, discusses the various RDS processes and identifies the particular station equation scheme by the RDS. Chapter III, "System Card and Project Tape," considers matters associated with the submittal of specific requests to the Roadway Design System and control of the project file. Chapters IV through XI discuss the individual processes which can be performed by RDS. Except for Chapter V, these processes have been grouped according to the specific aspects of roadway development to which they pertain. The processes included in Chapter V provides the capability to perform a number of specific geometric computations and plotting functions which could be helpful at any point throughout the design of a roadway. Job Control Language for executing RDS is given in Appendix A. A complete set of the RDS input forms is provided in Appendix B.
