Cross-cutting Issues

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.

This paper provides a background on the history of public wireless packet data networks, specifically Cellular Digital Packet Data (CDPD). Who has been using the network and how? Specifically, how has it been utilized in to serve the transportation industry? It also outlines the evolution currently underway in these networks. Why are billions of dollars being spent to build the next generation wireless networks? What standards are being utilized? What are the differences between service providers? How fast are the networks? When can we expect to see higher bandwidth? What applications are suitable to run on these networks? What technical issues need to be resolved? What will be the costs to utilize these networks?

The Alaska Department of Transportation and Public Facilities (ADOT&PF) is deploying a statewide Road Weather Information Systems (RWIS) network as part of their regional Intelligent Transportation Systems (ITS) architecture, the Alaska Iways Architecture Implementation (AI2). In Phase I, ADOT&PF installed 8 RWIS sites in the Anchorage area as a prototype to establish the type of equipment, site construction standards, and operational issues for future RWIS installations. Phase II calls for up to 31 additional RWIS in some of Alaska’s most remote and extreme weather prone areas of the surface transportation network.

This paper presents Broward County, Florida’s Advanced Traffic Management System (ATMS) communication network approach at various points in the design process, documenting such events as: lab tests, field tests and device deployment. As such, it is similar to a project engineering notebook, or a detail case study. The paper is divided into sections, with each section corresponding to a distinct design phase. Each section covers approximately 3 project months, and presents the goals, discoveries, approximations, choices and other considerations, which led to the subsequent design phase. This paper will serve as a living document to record the progress of the design until its conclusion, which is scheduled for late summer/early fall 2003.

Deployment of Intelligent Transportation Systems (ITS) can lead to significant impacts on the operation of a metropolitan area’s transportation system. This paper will review the documented impacts recorded in some of the U.S. cities that have been leaders in the deployment of ITS. Following a survey in 2000, 24 cities have been described as cities with a high level of ITS deployment by the USDOT’s ITS Deployment Tracking effort (www.itsdeployment.its.dot.gov).

Under the deployment tracking program, cities are defined as “high deployment” if they have achieved minimum threshold values of deployment in five component areas of ITS(Gordon, et al., 2001). These areas are Freeway Management/Incident Management,Transit Management/Electronic Fare Payment, Arterial Management, Regional Multimodal Traveler Information, and Emergency Management Services. Several of the cities with significant experience in deploying ITS are also developing a growing body of literature documenting the benefits that the systems can provide in the form of improved operation of the transportation network.
