This paper summarizes results of a recent study conducted by the Los Angeles County Metropolitan Transportation Authority (MTA), addressing coordination of existing and future Transportation Management Centers (TMCs). For Fiscal Years 1991-1999, the MTA programmed $212 million in capital costs to local agencies for Transportation Systems Management (TSM) projects. This funding includes costs for the design and implementation of signal systems infrastructure, as well as Transportation Management Centers (TMCs). Given the substantial amount of funds allocated to local agencies during this eight year period, MTA aims to establish objectives for defining a formal investment strategy for TMCs through this study to identify whether it should allocate funds towards establishing: (1) a regional TMC; (2) a network of regional and subregional TMCs or (3) a network composed of regional, subregional and local TMCs. This paper is organized as follows: Introduction: Summarizing the goals and objectives of the study. Existing Conditions: Addressing results of TMC survey of 14 agencies, including their annual cost, their architecture, and other pertinent information. Architecture Analysis: Analysis summary of eight different architecture options articulating their attributes and characteristics. Recommendations: Summarizing the recommended architecture and elaboration of its characteristics and overall investment strategy. TMC Implementation:Recommended approach to implementation is provided, addressing cost, O&M issues, multi-modal functions as well as multi-jurisdictional opportunities. Definition of Terms: Terms frequently used throughout the study is defined and clarified. The study was conducted in Spring 1997 under the direction of an "Oversight Committee" with representatives from the MTA, Los Angeles County DPW, Caltrans, and cities of Lancaster, Long Beach, Los Angeles, and Pasadena. Several meetings and discussion sessions were conducted addressing institutional and technical issues associated with various architectures. This paper provides an overview of the analysis and recommendations prepared for this project. Definition of terms has been provided at the end of the paper. |
