The iFlorida Bridge Security Monitoring System consisted of a software and hardware system that automatically monitored video images of the bridge and its vicinity and activated an alarm whenever…
As part of the iFlorida Model Deployment, the FDOT conducted a vulnerability assessment for the District 5 (D5) Regional Traffic Management Center (RTMC). The purpose of the assessment was to…
At the start of the iFlorida Model Deployment, FDOT managed about 45 dynamic message signs (DMS) deployed along I-4. Most signs were used to display delay and incident information, with a small…
An activity funded as part of the iFlorida Model Deployment was the development of an emergency evacuation plan for the Daytona International Speedway. This section of the report summarizes the…
As part of the iFlorida Model Deployment, FDOT deployed the field hardware needed to support a variable speed limit (VSL) system on a portion of I-4 and maintained a network of loop detectors on I-4…
During the course of the iFlorida evaluation, several approaches were discussed for reducing the overall costs of owning and operating traffic monitoring equipment. These approaches are discussed…
One common source of device failures at FDOT was fiber cuts, which left field devices disconnected from the Regional Traffic Management Center (RTMC). The main cause of fiber cuts on the FDOT network…
With iFlorida Model Deployment, there was a significant increase in the number, types, and geographic distribution of field equipment that FDOT District 5 (D5) was required to maintain. In January…
The primary objectives of the various Florida Department of Transportation (FDOT) interfaces to the Florida Highway Patrol Computer Aided Dispatch (FHP CAD) system were to provide the FDOT Regional…
FDOT, aware of the problems with the Condition Reporting System (CRS) software and anticipating the potential that it might fail, had begun testing SunGuide, a replacement for the CRS, in November…
As noted previously, FDOT experienced significant difficulties in reaching its objectives with the iFlorida Model Deployment. Early in the deployment, the problems were centered on the deployed field…
As part of the iFlorida Model Deployment, FDOT deployed a network of toll tag readers that were used to estimate travel times on seven Orlando arterials and on portions of several limited access toll…
An extensive network of traffic monitoring equipment was deployed and used to provide traveler information via 511, the Internet, and electronic signs. Taken together, the Central Florida and…
Some of the challenges faced by FDOT centered on limitations and failures of the Condition Reporting System (CRS) software. FDOT, aware of the problems with the CRS and anticipating the potential…

State DOTs increasingly contract with private, for-profit firms for highway maintenance services as a means to make up for inadequate staffing at the government level, a need for specialized…
Many TOCs in the country have now entered into their second-generation life cycle and have successfully implemented day-to-day TOC operations in their jurisdictions. TOCs from California, Minnesota,…
Weather events have both major and minor impacts on transportation management operations. During seasonal weather events, these impacts may include reduced traffic flow or increased traffic incidents…
Transportation Management Centers are established around the country to integrate data, information, and systems in support of day-to-day traffic and emergency operations. Incomplete or inaccessible…
In addition to highlighting current best practices for emergency integration and ways to improve current levels of integration, this study recommends investment in the development of new methods and…
A final report for the SE process improvement review was completed in April of 2005. The report provides descriptions of the successful SE applications, areas where the application of SE needs…
The key to a successful interoperable transportation system is to integrate ITS via a systems engineering approach into all stages of planning, designing and deployment of transportation projects at…
Institutional integration is key to the success of ITS projects. It is often difficult to bring agencies and other stakeholders together and sustain the relationships required to effect efficient…
Many coastal states have a need for near real-time traffic information to support traffic monitoring during a hurricane evacuation. Deploying traffic monitoring devices to collect this information…
The breakdown in the effectiveness of the transportation system during a hurricane evacuation has spurred a renewed interest in evacuation planning both within individual states and at the Federal…
Utilize clearance time incentives when contracting with towing service providers to reduce incident clearance times.
The use of this incentive driven contracting mechanism and implementation of the…
Adaptive Signal Control Technology (ASCT) systems collect data, evaluate traffic signal performance based on functional objectives, and then update signal timing in response. Florida DOT commissioned…
