Supply Analysis

Abstract

Transportation supply refers to all physical elements of the transportation system, including vehicles (e.g. trucks, barges, buses, and rail cars) and fixed facilities (e.g. highways, rail lines, ports, and airports). Inventory activities provide inputs for the supply analysis and the diagnosis serves to focus the analytical activities. In this methodology the supply analysis is limited in scope. It is a technical phase aimed at providing inputs and analytical tools for subsequent phases of the planning process. Improvements in the system that can be realized in the near future are dealt with in a separate section because short-run operational and capital improvements are considered to be a critical element: they are considered within Future Modal Options (J).
