Safety Evaluation of the Removal of Not-needed Traffic Signals (SIGEVAL II.

Résumé du livre

When the original MSY/MDOT SIGEVAL project was concluded in 1994, the software was provided to the general engineering community through the FHWA software distribution program at the McTrans Center for Microcomputers in Transportation. The program was developed originally as a DOS package. Since it was offered to the public, there have been many requests to upgrade the program into more of a "windows" application, where the program input could be made with dialog boxes, pull-down menus, scroll-down windows, and other graphical user interfaces rather than through conventional keyboard methods. In addition, since the conclusion of the project, the chapter of Highway Capacity manual (TRB, 1994) related to signalized and unsignalized intersections were significantly modified, and the related HCS (USDOT, 1987, 1994) software was appropriately upgraded. The input data file structure for both types of intersections changed significantly, with the result that the data file generation portions of the original SIGEVAL program were no longer valid
