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.

This report, prepared by the Florida Department of Transportation (FDOT) District IV ITS Office, is the second annual report for the SMART (“Systems Management for Advanced Roadway Technologies") SunGuide Transportation Management Center (TMC) located in Fort Lauderdale, Florida. This annual report reviews the performance of the ITS operations and summarizes the return-on-investment or benefit/cost ratio outcome that was calculated for 2005.

Several tests, focusing on the effects of the type and composition of cementitious materials, mechanical properties and durability of 60MPa high-strength concrete, were performed to provide experimental data for application of high-strength concrete to prestressed bridges. Mechanical properties, such as compressive strength, modulus of elasticity, splitting tensile strength and flexural strength, were determined. Durability related properties, such as hydration temperature, resistance to chloride-ion penetration, resistance to freezing-thawing, autogenous and drying shrinkages and creep were also determined. The effects of cementitious materials on high-strength concrete properties have been demonstrated. It was verified that 60MPa high-strength concrete revealed better structural and durability performances. Field test construction and performance follow-up survey for prestressed concrete bridge were performed. It was searched out that structural performance of 60MPa HSC members was improved.
