Abstract:
This report identifies the key issues that must be considered by state and other highway operating agencies in selecting traffic equipment for collecting the truck volumes and load spectra needed for analysis and design of pavement structures. The report also identifies steps that must be taken to ensure that the equipment performs appropriately and that, as a consequence, the data collected accurately describe the vehicles being monitored. The report is a useful resource for state personnel and others involved in the planning and design of highway pavements and structures.

Abstract:
The SWIFT (Seattle Wide-area for Travelers) project was a field operational test of a wide area ITS communications system using a flexible FM sub-carrier High Speed Data System (HSDS). The test was conducted in a partnership with WSDOT, King County Metro Transit, Delco Electronics, Inc., IBM, Seiko Communications Systems, Metro Traffic Control and the Federal Highway Administration. Three devices were used, by the public, to receive the traveler a Delco car radio (capable of providing vector navigation in addition to personal paging and the messages); a Seiko wrist watch pager; and a portable computer (capable of providing graphic displays of traffic advisories and bus positions). After the 15-month test, interviews with the 600 Seattle commuters/participants were conducted to assess user acceptance. A communications study evaluated the adequacy of the HSDS system to disseminate traveler information. Architecture study assessed the effectiveness of the various components to carry out SWIFT operations. institutional issues study documented the history of the project and assessed the institutional issues confronted. A deployment cost study investigated the cost of deployment of a SWIFT system and assessment of potential profitability. The first five reports in this series detail individual aspects of the project.

Abstract:
This report examines the feasibility of implementing an automated vehicle toll collection system for the Washington State Ferry System. The study concluded that such a system would pay for itself in four to five years. Impelementation of such a system is not recommended at this time, but it should be considered after similar projects, ongoing in other states, demonstrate that the AVI technology has achieved the accuracy and reliability requirements of a toll collection system.
