Operational Scenarios. The Thermal Control Subsystem performance shall be evaluated using the following operational scenarios for the range of orbits specified in Section 3.2.1.1.2.1
Operational Scenarios. There are three separate operational components to the ADR facility. The first two, are the skid pad and kart track. These however, are not included in the noise model. This is due to limited information available on these operations at the time of this study, as well as the dominance of road course noise levels at sensitive receptors. The third operational component, and primary focus, of this study is the main road course. Two operational scenarios for the main road course were investigated as outlined in Table 3 below. Scenario 1 is a typical quiet day usually experienced during weekday operation. Scenario 2 is considered worst case, from an operational noise level perspective, that might happen on a very busy weekend.
Operational Scenarios. Under normal conditions, roadway sensors will be collecting a variety of data on various roadway traffic characteristics, including: travel time/speed, traffic counts, and occupancy. This data will be fused and processed by existing systems, as well as the iFlorida Conditions System (developed under a separate iFlorida procurement). Several alert scenarios relate to the devices’ deployed under this procurement. Below are several sample scenarios for an alert mode. Incident on SR 417 – Due to the provision of information indicating reduced speeds and significantly increased travel times for a given roadway segment, an alarm is initiated on the monitor of the RTMC operator. At the same time, the system wide web-based speed map has been adjusting the color code for this roadway segment accordingly. The RTMC operator subsequently utilizes a nearby CCTV camera (controlled from the RTMC) to further investigate the alarm and discovers that there has been an accident and two lanes of traffic are blocked. The RTMC operator then initiates the proper response procedures and coordinates with other RTMC staff and representatives of other agencies as appropriate. In addition, the RTMC operator coordinates with a representative of the 511-telephone system to disseminate an appropriate message concerning the accident. Hurricane Evacuation of the east coast of Florida – A category 3 hurricane is heading towards the eastern coast of Florida and is anticipated to make landfall just south of Daytona. Local residents have been advised to evacuate coastal areas and seek refuge inland. Utilizing the Hurricane Evacuation System (HES) and new monitoring infrastructure deployed as part of iFlorida, traffic congestion levels are monitored on key evacuation routes. The HES only monitors the Brevard County area. At present, the monitored region includes a few miles on I-95 and SR 528. Other key evacuation routes are listed on the Florida Emergency Management website (xxxx://xxxxxx.xxxxxxx.xxxxxxxxxxxxxxx.xxx/). Subsequently, RTMC staff observe that one of the posted evacuation routes is not being utilized anywhere near capacity, while other routes are at/above capacity. To remedy this situation, the RTMC operator utilizes the DMS system to inform motorists of the availability of the alternate route.
Operational Scenarios. Under everyday conditions, incident and events will continue to come into the Orlando Operations Center via 911, cell phone, and radio. With the integration of the TMC into the OOC and the availability of information from the iFlorida Conditions System website (i.e., segment travel times and localized weather information), Orlando public safety agencies will have the additional capability of detecting incidents and events via significant increases in segment travel times and the scanning of CCTV images. Additionally, the exact location of incidents and events of which TMC staff become aware due to a call to 911 may be more quickly confirmed via an examination of current CCTV images and changes in segment travel times. Overall, as a result of the coordination and co-location of staff, everyday traffic management functions will be conducted more efficiently and effectively. Under emergency conditions, that is, a major incident or event expected to impact fire, police, emergency services, and travelers over an extended period of time and require the activation and implementation of emergency management plan(s), the Orlando Operations Center will be the focal point for all emergency management activities. In this mode, all necessary public safety and transportation management resources and staff will be more efficiently and effectively utilized.
Operational Scenarios. This project will support a single scenario or mode of operation. The project will collect and integrate weather-related data from the Central Florida region with weather-related data from Northern Florida. This integrated weather-related data will be provided to both the National Weather Service and Meteorlogix for further processing.
Operational Scenarios. This project will support a single scenario or mode of operation. This project will collect data, process it, and provide refined data sets to the iFlorida Conditions System for its use. Statewide travelers will be able to access current and forecasted weather via the statewide road segments map found on the “XxXxxxxxx.xxx” web site (generated by the iFlorida Conditions System). For access to current and forecasted Central Florida-oriented road segment weather information generated by the Conditions System, the “XxXxxxxxx.xxx” web site will transparently forward users to the Central Florida “xXxxxxxx.xxx” web site. For access to current and forecasted Central Florida-oriented 511 road segment weather information generated by the Conditions System, the traveler shall utilize FDOT District 5’s 511 telephone service.
Operational Scenarios. In the normal monitoring mode, bridge motion detector sensors will focus on key security related areas (e.g., bridge roadway shoulders, areas beneath the bridge decks, approaches to bridges, etc.) and provide continuous monitoring of all security-related events. In the alarm/alert mode (which occurs when a bridge mounted security monitoring device is triggered), the VSOC system will automatically notify specific FHP and FDOT locations. Alarms and alerts will also trigger the automatic, real-time digital recording of events for post event analysis. Bridge-related FHP and FDOT alert recipients are summarized as follows: • Xxxxxx Xxxxxx Bridge - Jacksonville FHP, Troop G* - FDOT District 2 TMC - FDOT District 5 RTMC • Xxxxxxx Causeway Bridge - Brevard County 911 Center* - Brevard County TMC - Brevard County FHP Substation Troop D* - FDOT District 5 RTMC - FHP Troop D * First Responder First responders will have the ability to initiate automatic call-up of cameras covering the location of a detected alarm and interactive camera call-up for the verification of a security event. Upon review of available information, the first responder will make a determination concerning the validity of the alarm and contact appropriate resources to investigate the event. As part of the post-event analysis mode, the documentation of both the video and the sequence of alarms and events can assist with post-event decision analysis and provide lessons learned for others. As per state law, all FDOT video recordings are erased after 30 days. The iFlorida partners have already held meetings with Florida Department of Law Enforcement (FDLE) officials to ensure that any FDOT bridge related security event recordings will be classified as evidence and tuned over to FDLE officials for further action.
Operational Scenarios. In the normal, automatic operating mode, Conditions System data will be collected, fused, and disseminated to FDOT and travelers via the web sites and the 511 systems. In the alert mode, the Conditions System will automatically provide alerts to the RTMC operator that something requires immediate attention. Below are sample scenarios that would initiate an alert mode. • Recurring congestion along I-4 in Downtown Orlando – During a typical weekday, traffic begins to back up in the downtown area due to the increased demand placed on the road by those leaving work. As the speed of traffic begins to slow below the posted speed limit, the RTMC operator receives an alert from the Conditions System specifying the problem and suggesting a potential solution. The Conditions System operator subsequently acknowledges the alert and requests that the RTMC operator to change the posted limit on specific variable speed limit signs from 65 MPH to 45 MPH. The Conditions System operator will now use the system to observe the effect of the speed reduction on traffic. The Conditions System will also have the capability to enable users to view archived data (i.e., speeds) for the periods of time during which the speed limit signs were modified. These tools will enable Conditions System/RTMC operators to make more informed decisions concerning the timing, duration and speeds selected. It is expected that over time, a pattern of optimum speed limit changes will be attained. Meanwhile, the Conditions System will continue to evaluate the current traffic conditions, determining if a different Central Florida 511 Scenario should be selected based upon current travel times. If the travel times dictate that a different scenario should be selected, then an appropriate pre-recorded announcement (.WAV file) will be delivered to the Central Florida 511 Telephone System and the RTMC operator will be alerted that a change has been made. If the RTMC operator determines that the current traffic conditions warrant a different announcement than the one selected, the RTMC operator has the option to create an override message that will replace the announcement delivered to the Central Florida 511 Telephone System. • Calculating a Roadway Diversion Message – The Conditions System will calculate and compare the travel times a southbound trucker or other traveler might encounter while traveling from the northern intersection of I-4 and S.R. 417 to the I-4 Disney area. For this to occur, two calculat...
Operational Scenarios. The current operational mode is daily polling of the 54 sites, with the capability to shift to hourly polling during emergency situations. The goal of this project is continue a single operational mode, however, at an enhanced polling rate, which is still to be determined.
