Indemnification Costs in the Dam Safety Decision
The ASCE Task Committee on Spillway Design Floods has proposed safety criteria for three categories of dams. Category 1 dams are those with anticipated failure consequences so large and...
Use of the DEB Model in MARTA's Service Planning
The Metropolitan Atlanta Rapid Transit Authority (MARTA) is in the process of expanding bus and rail services. The expansion program requires the preparation of annual and five year system...
Use of a Schedule and Runcut Simulator
The development of a computer program which simulates the transit scheduling and runcutting processes is discussed. The program, called OCRS, was developed for the Multi-Corridor Project...
Running Rucus II on a Microcomputer
Since the preliminary version of the RUCUS II (Run Cutting and Scheduling System) was released by UMTA in 1982, the system has achieved considerable acceptance by transit properties. These...
Seven Myths of Managing Microcomputers
Microcomputer usage in the transportation community has grown so rapidly in recent years that it seems sometimes that we are being overwhelmed, and maybe oversold, by the technology. As...
Sell Your Organization on the Seven C's for Effective Microcomputer Management
