This report documents the evolution, development, and lessons learned while attempting to identify, modify, and deploy Intelligent Transportation System (ITS) and advanced technology tools to facilitate coordination of public transit and social (human) service transportation and mobility management in a one stop shop located in Modoc County (northeast), California. The report summarizes planning and coordination efforts; shares challenges, lessons learned, and outcomes; and concludes by identifying some issues and structural obstacles that diminish usability and impede transfer of functional ITS tools for purposes of data collection, management, and reporting.

The growing number of traffic safety strategies, including the Intelligent Transportation Systems (ITS) and lowcost proactive safety improvement (LCPSI), call for an integrated approach to optimize resource allocation systematically and proactively. While most of the currently used standard methods such as the six-step method that identify and eliminate hazardous locations serve their purpose well, they represent a reactive approach that seeks improvement after crashes happen. In this project, a decision support system with Geographic Information System (GIS) interface is developed to proactively optimize the resource allocation of traffic safety improvement strategies. With its optimization function, the decision support system is able to suggest a systematically optimized implementation plan together with the associated cost once the concerned areas and possible countermeasures are selected. It proactively improves the overall traffic safety by implementing the most effective safety strategies that meet the budget to decrease the total number of crashes to the maximum degree. The GIS interface of the decision support system enables the users to select concerned areas directly from the map and calculates certain inputs automatically from parameters related to the geometric design and traffic control features. An associated database is also designed to support the system so that as more data are input into the system, the calibration factors and crash modification functions used to calculate the expected number of crashes will be continuously updated and refined.

This project has developed and implemented a software environment to utilize data collected by Traffic Management Centers (TMC) in Florida, in combination with data from other sources to support various applications. The environment allows capturing and fusing the data from multiple sources. The combined data can support the performance measurements of transportation system, transportation system modeling, assessment of the benefits of Intelligent Transportation System (ITS) applications such as incident management, ramp metering, and so on, and discovery of different relationships and associations of attributes through data mining and visualization methods. The developed modules are demonstrated in a series of use cases.

Systems Theory represents a significant theoretical backgrounds for any professional undertaking within the branch of ITS. There are several approaches to elaborating this kind of theory. For engineering purposes (i.e. also for ITS) the classical approach: GTS - General Theory of Systems which is based on ideas of Karl Ludwig von Bertalanffy [1] and his co-workers is probably the most beneficial. A purposeful source of knowledge on the internet is [2]. An excellent review of fundamental Systems ideas is provided in the works of G.J. Klir [3, 5]. Both innovative and thorough insight into the engineering utilizations of Systems ideas is presented by J. Vlcek [4].

Telematics is a result of convergence and following progressive synthesis of telecommunication technology and informatics. The effects of telematics are based on synergism of both disciplines. Telematics can be found in wide spectrum user areas, from an individual multimedia communication towards intelligent use and management of large-scale networks (e.g. transport, telecommunications, public service). Advanced telematics provides intelligent environment for knowledge society establishment and allows expert knowledge description of complex systems. It also includes legal, organizational, implementation and human aspects.

Traffic congestion burdens the nation's quality of life and will likely grow substantially if current trends continue. Intelligent Transportation Systems (ITS) are a range of technologies that can reduce congestion at less cost than some other approaches. The U.S. Department of Transportations (DOT) Research and Innovative Technology Administration (RITA) is responsible for promoting and supporting the use of ITS in coordination with other modal administrations, including the Federal Highway Administration (FHWA). Since 1994, DOT has overseen the allocation and expenditure of more than $3 billion for deploying and researching ITS. GAO was asked to address (1) the current and emerging uses of ITS technologies by state and local governments, (2) the challenges these governments face in using ITS, and (3) the extent to which DOT's efforts to promote and support ITS address these challenges and follow leading practices. To conduct this work GAO visited four sites, and interviewed and analyzed documents and data from DOT and state and local transportation officials, ITS experts, and other stakeholders.

The purpose of this effort was to conduct a border-wide assessment of the use of intelligent transportation systems (ITS) technologies and operational concepts at and near land border crossings between the U.S. and Mexico. The work focused on tolling, traffic management and operations, and safety. The specific objectives of this project were to research, assess and document how ITS technologies can be used in areas of: Toll collection and management in border regions, identifying technology used, system components, and any special data sharing arrangements between the two countries. Transportation operations and traffic management in US/MX border regions. Transportation safety policy and operations. Traffic management, traffic operation and traffic enforcement on tolled roads/tolled border-crossing roads. Archiving toll and traffic management data.
