Vehicle Longitudinal Control and Reliability Project. Longitudinal and Lateral Control Cost and Weight Model.

摘要

UMTA's Automated Guideway Transit Technology (AGTT) Program is oriented toward the analyses of systems and the development of system elements which may be used in a variety of advanced urban transportation systems. The Vehicle Longitudinal Control and Reliability (VLCR) Project is the part of the AGTT program that focuses on the performance of longitudinal control systems. The project includes a review of the status of existing technology,specification of design goals and requirements,detailed mathematical modeling,analysis and simulation,development and specification of design concepts and their mechanizations,and experimental validation of the designs. This document describes an automated cost and weight model for Vehicle Longitudinal and Lateral Control (VLC) Systems. The model is a life-cycle cost and weight model which focuses on system components which vary with lateral control option. This model is to be used to evaluate the cost and weight of VLC designs for four classes of AGT (GRT) large and small,and Personal Rapid Transit (PRT). The report is organized in three technical sections: (1) Methodology and model description (includes design goals,model structure,basic equations,and a detailed description of the model; (2) Model use (includes input requirements,output and factor selection;and (3) Model growth potential. Conclusions are provided in the last section with the model code reproduced in the Appendix. The authors state that a usable life-cycle cost and weight model is available for immediate application to AGT nominal designs and control alternatives.
