Chapter 2 - Introduction and Methodology

摘要

Efficient planning, design, construction and maintenance operations require accurate, dependable and electronically based methods of positioning and locating specific facilities, operations, and needs. These methods must be logically linked with other organizational electronic management systems to optimize overall operational efficiency. Recognizing these objectives, NCHRP Project 20-27 was initiated with the objectives of: (1) establishing consensus-based functional requirements for a multi-dimensional LRS data model for multimodal transportation systems, (2) developing an improved LRS data model, and (3) developing guidelines to implement an improved LRS data model in transportation organizations. The results of that research are published via NCHRP Report 460.
