In the fall of 1995 the Maryland State Highway Administration (MSHA) decided to take a closer look at how to build an affordable ITS network to support its growing Chesapeake Highway Advisories for Routing Traffic (CHART) program. In doing so, the MSHA departed from the prevalent ITS practice of building a private fiber optic telecommunications infrastructure in favor of first performing a telecommunications analysis to determine if a build option was the most cost-effective approach for meeting its telecommunications needs. This communications analysis was the second of two studies that MSHA undertook using a systems engineering approach to define a communications infrastructure that met its business needs. This report describes Marylands experience in performing an ITS telecommunications analysis including: the reasons for performing the analysis, the approach used, the findings of the analysis, lessons learned, the merits and drawbacks of performing such an analysis and some considerations other DOTS may want to use in making a similar decision. |
