Floating Car Data
Floating car data (FCD) in traffic engineering and management is typically timestamped geo-localization and speed data directly collected by moving vehicles, in contrast to traditional traffic data collected at a fixed location by a stationary device or observer. In a physical interpretation context, FCD provides a Lagrangian description of the vehicle movements whereas stationary devices provide an Eulerian description. The participating vehicle acts itself consequently as a moving sensor using an onboard GPS receiver or cellular phone. The most common and widespread use of FCD is to determine the traffic speed on the road network. Based on these data, traffic congestion can be identified, travel times can be calculated, and traffic reports can be rapidly generated. In contrast to stationary devices such as traffic cameras, number plate recognition systems, and induction loops embedded in the roadway, no additional hardware on the road network is necessary.

Fleet Vehicle
Fleet vehicles are groups of motor vehicles owned or leased by a business, government agency, or other organization rather than by an individual or family. Typical examples include vehicles operated by car rental companies, taxicab companies, public utilities, public bus companies, and police departments. In addition, many businesses purchase or lease fleet vehicles to deliver goods In economics, goods are items that satisfy human wants and provide utility, for example, to a consumer making a purchase of a satisfying product. A common distinction is made between goods which are transferable, and services, which are not ... to customers, as well as provide vehicles for sales representatives to travel to clients. In some jurisdictions and countries, fleet vehicles can also be privately owned by employees. These vehicles are called the 'grey fleet' and are used for work purposes. Fleet vehicles can be managed by a fleet manager or transport manager using fleet management ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
E-ZPass
E-ZPass is an electronic toll collection system used on toll roads, toll bridges, and toll tunnels in the Eastern United States, Midwestern United States, and Southern United States. The E-ZPass Interagency Group (IAG) consists of member agencies in several states, which use the same technology and allow travelers to use the same transponder on toll roads throughout the network. Since its creation in 1987, various independent systems that use the same technology have been folded into the E-ZPass system, including the I-PASS in Illinois and the NC Quick Pass in North Carolina. Negotiations are ongoing for nationwide interoperability in the United States (see ). Functionality Technology E-ZPass tags are active RFID transponders, historically made by Kapsch TrafficCom (formerly Mark IV Industries Corp—IVHS Division) under a competitively bid contract. They communicate with reader equipment built into lane-based or open-road toll collection lanes by transmitting a un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

5-1-1
5-1-1 is a transportation and traffic information telephone hotline in some regions of the United States and Canada. Travelers can dial 511, a three-digit telephone number, on landlines and most mobile phones. The number has also extended to be the default name of many state and provincial transportation department road conditions Web sites, such as Wisconsin's site. It is an example of an N11 code, part of the North American Numbering Plan. 5-1-1 services in the United States are organized by state or region. Some 5-1-1 services are limited to information for drivers regarding road conditions and traffic. Other services have a wider scope, also providing information on public transport, carpooling and other services.

Traffic Flow
In mathematics and transportation engineering, traffic flow is the study of interactions between travellers (including pedestrians, cyclists, drivers, and their vehicles) and infrastructure (including highways, signage, and traffic control devices), with the aim of understanding and developing an optimal transport network with efficient movement of traffic and minimal traffic congestion problems. History Attempts to produce a mathematical theory of traffic flow date back to the 1920s, when Frank Knight first produced an analysis of traffic equilibrium, which was refined into Wardrop's first and second principles of equilibrium in 1952. Nonetheless, even with the advent of significant computer processing power, to date there has been no satisfactory general theory that can be consistently applied to real flow conditions. Current traffic models use a mixture of empirical and theoretical techniques. These models are then developed into traffic forecasts, and take account of p ...

Toll Road
A toll road, also known as a turnpike or tollway, is a public or private road (almost always a controlled-access highway in the present day) for which a fee (or ''Toll (fee), toll'') is assessed for passage. It is a form of road pricing typically implemented to help recoup the costs of road construction and Road maintenance, maintenance. Toll roads have existed in some form since Classical antiquity, antiquity, with tolls levied on passing travelers on foot, wagon, or horseback; a practice that continued with the automobile, and many modern tollways charge fees for motor vehicles exclusively. The amount of the toll usually varies by vehicle type, weight, or number of axles, with freight trucks often charged higher rates than cars. Tolls are often collected at toll plazas, toll booths, toll houses, toll stations, toll bars, toll barriers, or toll gates. Some toll collection points are automatic, and the user deposits money in a machine which opens the gate once the correct toll ha ...

Radio-frequency Identification
Radio-frequency identification (RFID) uses electromagnetic fields to automatically Automatic identification system, identify and Tracking system, track tags attached to objects. An RFID system consists of a tiny radio transponder, a radio receiver and transmitter. When triggered by an electromagnetic interrogation pulse from a nearby RFID reader device, the tag transmits digital data, usually an Identifier, identifying inventory number, back to the reader. This number can be used to track inventory goods. Passive tags are powered by energy from the RFID reader's interrogating radio waves. Active tags are powered by a battery and thus can be read at a greater range from the RFID reader, up to hundreds of meters. Unlike a barcode, the tag does not need to be within the Line-of-sight propagation, line of sight of the reader, so it may be embedded in the tracked object. RFID is one method of automatic identification and data capture (AIDC). RFID tags are used in many industries. For e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
