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.

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.

Since the late 60’s the New York City Department of Transportation (NYCDOT) has been operating and expanding its Vehicular Traffic Control System (VTCS) in order to help manage traffic signal timing and coordination throughout the city. Currently over half of the city’s 12,000 plus signalized locations are under VTCS control. Due to the city’s vast size, NYCDOT currently employs various means of communicating with remote signalized locations. These communication methods include a city owned and operated coaxial cable system within the borough of Manhattan. In the remaining four boroughs, NYCDOT utilizes dedicated twisted pair telephone lines to communicate with the traffic signals on the VTCS system. In addition to the traffic signal system, NYCDOT employs the VTCS to operate over 70 traffic surveillance cameras within Manhattan.

This paper focuses on the primary public-private partnership (PPP) that often is formed after public-public partnerships have been created: those that occur as a result of the deployment of Advanced Traveler Information Systems (ATIS). More specifically, the private partner can play a variety of roles that range from efforts that remain almost separate from public efforts to collect, fuse and disseminate data to those in which the private partner is hired to perform all ATIS related functions. Whether or not these partnerships are successful or effective has been difficult to assess in most metropolitan areas where deployment has already occurred. In general, using the criteria of numbers of users that subscribe to customized or specialized ATIS services, low numbers of users indicate a decided lack of success in many instances.

This paper reports the results of a study of key success factors of integrated traffic management and emergency response systems. The study relied on the methods of survey research to specify a research model, create measures of the research variables, develop an appropriate sampling frame, administer the survey, analyze the results, and report and share the findings. The focus was on calibrating important success factors of integrated programs to reach clear conclusions about what works and what doesn’t work – and the circumstances that impact success or failure. The study is unique because it developed quantitative measures of the nature and quality of stakeholder relations. The measures are evaluated and assessed in terms of their usefulness for developing a better understanding of both the success factors as well as the limiting factors – the elements of collaborative inertia – that hold back projects from reaching their full potential. The findings are critical to stakeholders who recognize the benefits of working to integrate traffic management and emergency response systems and need to make the best use of their limited resources toward this goal.
