Cross-cutting Issues

In 2003, PB Farradyne under the guidance of the Oahu Metropolitan Planning Organization (OMPO) and support of Oahu’s transportation stakeholder agencies developed a Regional Intelligent Transportation System (ITS) Architecture for Oahu. The development of the Oahu Regional ITS Architecture was born from the need to improve safety, capacity, agency/system integration, communication, and mobility on Oahu. The objective of the Oahu Regional ITS Architecture effort, therefore, was to support ITS interoperability and joint operations initiatives amongst Oahu’s transportation and emergency response providers ultimately benefiting a broad range of Oahu’s transportation stakeholders. This paper summarizes the Oahu Regional Intelligent Architecture placing emphasis on the approach taken to develop the architecture, key aspects of architecture development, and the unique characteristics inherent to the region.

This paper presented a quantitative analysis framework for estimating the operational impact, in terms of delay, of adverse weather events on travel in the United States. The speed estimation methodology for travel in adverse weather was based on the Highway Capacity Manual methodology. Using the GIS and database tools, one can estimate travel delay and other relevant statistics at various resolutions including weather forecast zone, county, FHWA urbanized area, metropolitan area, state, and national levels. The estimation procedure employed NCDC's Storm Data and FHWA's HPMS and NHPN databases, which are all publicly accessible. The estimation procedure, as proposed, which can be implemented repeatedly to assess the change from one year to the next, was used to estimate adverse weather impacts for the year of 1999.

Palm Beach County, Florida has urgent needs for work zone safety and traffic and incident management improvements due to reconstruction of Interstate 95 and rail corridor improvements. In response, Florida DOT sponsored a fast track project to plan, design, build, operate and maintain a comprehensive traffic management system. The planning process confirmed the corridor needs, concept of operation and design requirements. The design determined software requirements, communications design, and field device placement in the context of interstate reconstruction. The Management Information System for Transportation (MIST) control platform is utilized with field devices by ADDCO Inc. The system is integrated with other ITSs within the region. The project demonstrates successful partnering by Florida DOT, FHWA, and the PB Farradyne Team to expedite the contracting process and complete the necessary studies, design, acquisition and deployment utilizing innovative contracting methods.

Cambridge Systematics, Inc. under subcontract to PB Farradyne, was hired by the Florida Department of Transportation (FDOT), District 6, to conduct a pre-deployment estimation of the impacts of ramp-metering on the I-95 corridor in Miami, FL. A total of twenty two I-95onramps in the vicinity of downtown Miami, are scheduled for ramp- metering starting in the year 2005. The purpose of this project is to estimate the impacts of ramp- metering on the I-95 corridor on the Miami-Dade County roadway network. The impacts estimation was performed using the ITS Deployment Analysis System (IDAS)1 model and will serve the following purposes:· The development of a technically sound regional IDAS model to assess the impacts of ramp metering on the I-95 corridor. · The results of the IDAS analysis will be used to identify ramp- meter sites for further data collection, simulation analysis and evaluation. · Communication of the expected impacts of ramp- metering to the traveling public in Miami- Dade County.

This paper is being submitted based on the assumption that the author is in charge of a private company focused on the ITS market, as suggested in Essay Topic 2. In this paper the author attempts to identify ITS-related products and services that have the greatest impact on saving lives, time, and money while providing opportunities for a successful business. More specifically, major conditions for private company investment in ITS-related public projects are briefly reviewed and benefits of electronic payment systems (EPS) for public transportation operators are discussed. Finally, a private sector view on the assessment of EPS investments is described and an approach to overcome its shortcomings is presented.
