Business Process Modeling for the Virginia Department of Transportation: A Demonstration with the Integrated Six-Year Improvement Program and Statewide Transportation Improvement Program: Executive Summary

摘要

In automating many of their business processes, the information technology (IT) divisions of transportation agencies need to set priorities and allocate resources for the development and maintenance of their IT applications. Developing business process models can support the agencies in deciding which systems have the greatest impacts relative to their required investments of resources. This research has been performed by the Center for Risk Management of Engineering Systems at the University of Virginia to support the Virginia Department of Transportation (VDOT), the Virginia Department of Rail and Public Transportation (VDRPT), the Federal Highway Administration (FHWA), and the Federal Transit Administration (FTA). Its purpose is to improve the business processes of the Virginia Transportation Six-Year Improvement Program (SYIP) for Construction and Development and the Statewide Transportation Improvement Program (STIP). The effort is a logical sequel to the document, Development and Financial Constraint of Virginia's STIP (FHWA et al. 2002), which describes the federal interest in transforming the state's SYIP into the federal STIP. This report is organized as follows. The Purpose and Scope section is an overview of the SYIP/STIP process and presents some recent challenges implementing the two documents. The Methods section describes the functionality of IDEF (Integrated Definition for Function) modeling, the development of an IDEF Worksheet, and the AllFusion/BPWin software that supports IDEF modeling. The Results and Discussion section provides an overview of the technical results that are presented in full detail in the appendices. The Conclusions section discusses the findings of the effort. The Recommendations section addresses implementation of the findings by three divisions of the highway agency: planning, programming, and information technology. Twelve Appendices provide the technical results of the effort.
