Cross-cutting Issues

The Ports ATMIS, which will improve traffic flow for both Ports as well as the adjacent regional transportation system, consists of the following components: 1. Port Transportation Facility Security System/Emergency Response and Evacuation System 2. Advanced Transportation Management System (ATMS) 3. Advanced Traveler Information System (ATIS) 4. Communication System

The authors hope that this paper would benefit those agencies intersted in development of an ITS program focusing on a Systems Engineering approach that included Concept of Operations and Configuration Management.

This paper explores impacts of ramp metering on urban land use. A regression-based transportation model is developed to capture changes in accessibility caused by ramp metering on a highway network. A Land Use Change Indicator (LUCI) model is modified to estimate how the spatial distribution of employment and housing would change in response to the redistributed accessibility in five hypothetical urban areas with various initial land use patterns. Results show that ramp metering can affect land use in various ways depending on initial land use conditions. Ramp metering can exacerbate decentralization, but not necessarily sprawl.

This report is the second and final of two reports to identify and recommend performance measures to assess the ITS program in District 4. The focus of the District 4 ITS performance measurement program is to measure outcomes and activities that are responsibilities of the Traffic Operations Division. The measures reported will be the accountability assessment of the District’s ITS Program. Data on activities conducted by partner agencies may be collected but will not be reported as part of this program. The first report produced in May 2005 describes the development of a data collection plan and performance measures that will complement a number of existing Florida DOT activities and assist in achieving the goals and objectives established by the District. This task is intended to assist the District in meeting the goals and objectives of the ITS Business Plan and in achieving the stated vision of being the number one ITS program in the United States and will further the District as a leader in Florida in data collection and performance monitoring.

An Intelligent Transportation Systems (ITS) communications architecture is emerging with ITS-specific standards for several layers of the International Standards Organization Open Systems Interconnections (OSI) communications reference model. However, these standards neither fully leverage the advantages of a standards-based architecture, nor fully address ITS-specific security and networking requirements. This paper rectifies these shortcomings by describing a reorganization of the emerging standards and the addition of protocols for two additional OSI layers. The result is an improved communications architecture for ITS networks.

This case study explores the evolution of the I-95 Corridor Coalition - a “virtual” organization created in 1993 by twenty-six Northeastern transportation agencies. New approaches were needed to solve complex transportation problems prevalent in this twelve-state corridor. Recognizing the need to increase the capacity of existing systems through improved management and operations, these autonomous agencies formed a coalition to coordinate their use of Intelligent Transportation Systems (ITS), and received USDOT “Priority Corridor” funds to enable this effort.
