COST-EFFECTIVENESS OF PASSING LANES: PROGRAMMER'S MANUAL
Program PCL is an interactive, screen-oriented, menu-driven, PC-based software package for the analysis of the effect of adding passing or climbing lanes to selected locations along two-lane rural highways. The main analysis functions are: a) choosing the start and end locations of a climbing lane based on the speed differential of a heavily loaded truck; b) predicting the effects on level of service and average speed of adding a passing or climbing lane; c) performing a cost effectiveness analysis based on reduction of delay and reduction in accidents. PCL provides extensive on-line help for the novice or inexperienced user, and is menu-driven for ease of use. The Programmer's Manual provides a general overview of program logic, and extensive documentation of the internal workings of some portions of the PCL program. It is intended for use by programmers who wish to make modifications to the program. The PCL program is written in ANSI Standard C, and comprises about 50 source files totalling approximately 17,000 lines and over 450K bytes (exclusive of screen handling libraries). The extensive use of PC-specific screen manipulation means that porting to other (non-PC) environments will be difficult.
