Georgia Navigator
Georgia Navigator (sometimes also as Georgia NaviGAtor) is an Advanced Traffic Management System used in the U.S. state of Georgia. It is operated by the Georgia Department of Transportation (GDOT), and was first activated in April 1996, just before the 1996 Summer Olympics in Atlanta. Metro Atlanta Most of the Georgia Navigator system is installed in metro Atlanta, where at least half of the state's population lives. It includes traffic cameras, changeable message signs, ramp meters, and a traffic speed sensor system. Unlike other ITS deployments around the world, Georgia Navigator almost exclusively uses video detection cameras to gather traffic flow data, as opposed to traditional sensors embedded in the pavement. Additionally, a portion of the system (Georgia 400 and parts of I-16, I-75 and I-85 outside of Atlanta) receives traffic flow information from floating car data gathered by anonymously tracking cell phones. All devices are connected by buried optical fiber, which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Advanced Traffic Management System
The Advanced Traffic Management System (ATMS) field is a primary subfield within the Intelligent Transportation System (ITS) domain. The ATMS view is a top-down management perspective that integrates technology primarily to improve the flow of vehicle traffic and improve safety. Real-time traffic data from cameras, speed sensors, etc. flows into a Transportation Management Center (TMC) where it is integrated and processed (e.g. for incident detection), and may result in actions taken (e.g. traffic routing, DMS messages) with the goal of improving traffic flow. The National ITS Architecture defines the following primary goals and metrics for ITS: * Increase transportation system efficiency, * Enhance mobility, * Improve safety, * Reduce fuel consumption and environmental cost, * Increase economic productivity, and * Create an environment for an ITS market. History In 1956, the National Interstate and Defense Highways Act initiated a 35-year $114 billion program that designed and ...

Weather Station
A weather station is a facility, either on land or sea, with instruments and equipment for measuring atmospheric conditions to provide information for weather forecasts and to study the weather and climate. The measurements taken include temperature, atmospheric pressure, humidity, wind speed, wind direction, and precipitation amounts. Wind measurements are taken with as few other obstructions as possible, while temperature and humidity measurements are kept free from direct solar radiation, or insolation. Manual observations are taken at least once daily, while automated measurements are taken at least once an hour. Weather conditions out at sea are taken by ships and buoys, which measure slightly different meteorological quantities such as sea surface temperature (SST), wave height, and wave period. Drifting weather buoys outnumber their moored versions by a significant amount. Weather instruments Typical weather stations have the following instruments: * Thermometer for ...

County (United States)
In the United States, a county is an administrative or political subdivision of a state that consists of a geographic region with specific boundaries and usually some level of governmental authority. The term "county" is used in 48 states, while Louisiana and Alaska have functionally equivalent subdivisions called parishes and boroughs, respectively. The specific governmental powers of counties vary widely between the states, with many providing some level of services to civil townships, municipalities, and unincorporated areas. Certain municipalities are in multiple counties; New York City is uniquely partitioned into five counties, referred to at the city government level as boroughs. Some municipalities have consolidated with their county government to form consolidated city-counties, or have been legally separated from counties altogether to form independent cities. Conversely, those counties in Connecticut, Rhode Island, eight of Massachusetts's 14 counties, and Alaska ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Induction Loop
An induction or inductive loop is an electromagnetic communication or detection system which uses a moving magnet or an alternating current to induce an electric current in a nearby wire. Induction loops are used for transmission and reception of communication signals, or for detection of metal objects in metal detectors or vehicle presence indicators. A common modern use for induction loops is to provide hearing assistance to hearing-aid users. Applications Vehicle detection Vehicle detection loops, called ''inductive-loop traffic detectors'', can detect vehicles passing or arriving at a certain point, for instance approaching a traffic light or in motorway traffic. An insulated, electrically conducting loop is installed in the pavement. The electronics unit applies alternating current electrical energy onto the wire loops at frequencies between 10 k Hz to 200 kHz, depending on the model. The inductive-loop system behaves as a tuned electrical circuit in which the lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
I-85
Interstate 85 (I-85) is a major Interstate Highway in the Southeastern United States. Its southern terminus is at an interchange with Interstate 65, I-65 in Montgomery, Alabama; its northern terminus is an interchange with Interstate 95, I-95 in Petersburg, Virginia, near Richmond, Virginia, Richmond. It is nominally north–south as it carries an odd number, but it is physically oriented northeast–southwest and covers a larger east-west span than north-south. While most Interstates that end in a "5" are cross-country, I-85 is primarily a regional route serving five southeastern states: Virginia, North Carolina, South Carolina, Georgia (U.S. state), Georgia, and Alabama. Major metropolitan areas served by I-85 include the Greater Richmond Region in Virginia, the Research Triangle, Piedmont Triad, and Charlotte metropolitan area regions of North Carolina, Upstate South Carolina, the Atlanta metropolitan area in Georgia, and the Montgomery metropolitan area in Alabama.

Interstate 285 (Georgia)
Interstate 285 (I-285) is an auxiliary Interstate Highway encircling Atlanta, Georgia, for . It connects the three major Interstate Highways to Atlanta: I-20, I-75, and I-85. Colloquially referred to as the Perimeter, it also carries unsigned State Route 407 (SR 407) and is signed as Atlanta Bypass on I-20, I-75, and I-85. Because of suburban sprawl, it is estimated that more than two million people use the highway each day, making it the one of the busiest Interstates in the Atlanta metropolitan area, and one of the most heavily traveled roadways in the US. During rush hour, portions of the highway slow, sometimes to a crawl. Route description I-285 is 8 to 12 lanes wide, with the northern part from I-75 to SR 400 to I-85 the most heavily traveled. One segment of the highway near Tom Moreland Interchange (a large, flyover highway interchange northeast of Atlanta colloquially called Spaghetti Junction) with I-85 widens to 18 lanes, including ...

Weather Forecast
Weather forecasting is the application of science and technology to predict the conditions of the atmosphere for a given location and time. People have attempted to predict the weather informally for millennia and formally since the 19th century. Weather forecasts are made by collecting quantitative data about the current state of the atmosphere, land, and ocean and using meteorology to project how the atmosphere will change at a given place. Once calculated manually based mainly upon changes in barometric pressure, current weather conditions, and sky condition or cloud cover, weather forecasting now relies on computer-based models that take many atmospheric factors into account. Human input is still required to pick the best possible forecast model to base the forecast upon, which involves pattern recognition skills, teleconnections, knowledge of model performance, and knowledge of model biases. The inaccuracy of forecasting is due to the chaotic nature of the atmosphere, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Local Insertion
In broadcasting, local insertion (known in the United Kingdom as an opt-out) is the act or capability of a broadcast television station, radio station or cable system to insert or replace part of a network feed with content unique to the local station or system. Most often this is a station identification (required by the broadcasting authority such as the U.S. Federal Communications Commission), but is also commonly used for television or radio advertisements, or a weather or traffic report. A digital on-screen graphic ("dog" or "bug"), commonly a translucent watermark, may also be keyed (superimposed) with a television station ID over the network feed using a character generator using genlock. In cases where individual broadcast stations carry programs separate from those shown on the main network, this is known as regional variation (in the United Kingdom) or an opt-out (in Canada and the United States). Automated local insertion used to be triggered with in-band signaling, suc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Florida Panhandle
The Florida Panhandle (also West Florida and Northwest Florida) is the northwestern part of the U.S. state of Florida; it is a Salient (geography), salient roughly long and wide, lying between Alabama on the north and the west, Georgia (U.S. state), Georgia on the north, and the Gulf of Mexico to the south. Its eastern boundary is arbitrarily defined. In terms of population, major communities include Tallahassee, Florida, Tallahassee, Pensacola, Florida, Pensacola, and Panama City, Florida, Panama City. As is the case with the other eight U.S. states that have Salient (geography)#Panhandles in the United States, panhandles, the geographic meaning of the term is inexact and elastic. References to the Florida Panhandle always include the ten List of counties in Florida, counties west of the Apalachicola River, a natural geographic boundary, which was the historic dividing line between the British colonies of West Florida and East Florida.
