Actual Taxi-Out Time (AXOT) is the time period between the Actual Off-Block Time (AOBT) and the Actual Take Off Time (ATOT). AXOT = ATOT - AOBT

Age and Gender Detection in Video Analytics is a function that automatically estimates age and gender of a person from an image, video or video stream.

Analog Security Cameras transmit the video feed via a coaxial cable. A digital video recorder (DVR) converts the analog signal to a digital signal and stores it on the hard drive.

An anchor tenant, also referred to as an anchor store or key tenant, is a significantly larger tenant in a mall, often a department store or chain of retail stores. They are usually found at the ends of shopping malls.

Anomaly Detection in Video Analytics is a function to identify abnormal situations or patterns in a video stream.

An anonymous people counter counts people in real time, without making use of any graphical or video data. This ensures anonymity, and protects the privacy of the detected objects identified as people.

Apron or Ramp is a designated area of an airport where aircraft are parked, unloaded, loaded, refueled, and boarded by passengers. The apron is typically located adjacent to the terminal building.

Average Transaction Value (ATV) refers to the average amount a consumer spends on a single purchase.

Business Intelligence (BI) is a process of analyzing data and presenting actionable information that helps executives, managers and employees within organizations to make informed business decisions.

Background Change Detection in Video Analytics is a function which detects the change of background of a video or video stream over time. A background change can be triggered by a change in perspective, constructions or a broken camera.

Bandwidth is the maximum data rate of available information capacity on a physical communication link. Bandwidth is equivalent to the maximum available bitrate and usually measured in megabits per second (Mbps).

A Bicycle Counter is a device installed at roads to measure bicycle traffic. Bicycle Counters can be realized with different technologies such as radar, lidar or security cameras.

Bitrate is the number of bits that are transmitted or processed over time.

The Block Time is the time of a flight measured from the start of movement ("off-block") to the end of movement ("in-block"). It includes taxi-out time, flight-time and tax-in time.

A bullet camera is a security camera with a cylindrical shape.

Constant Bitrate (CBR) as opposed to variable bitrate (VBR) keeps the bitrate of a signal during compression constant independent of the signal complexity. As a result the quality of the result can vary.

Communications-Based Train Control (CBTC) is a modern signaling and control system used in rail transportation.

A Closed Circuit Television (CCTV) system or video surveillance system comprises of security cameras and monitors (TV). Closed Circuit indicates that the system is restricted to authorized users.

A Central Processing Unit (CPU) is an electronic circuit designed to perform basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions in the program.

Calculated Take Off Time (CTOT) is the time calculated and issued by the appropriate Central Management unit, as a result of tactical slot allocation, at which a flight is expected to become airborne. (ICAO Doc 7030/4 – EUR, Table 7)

In retail stores, customer experience (cx) refers to the overall experience a customer has when interacting with a retailer, whether it's in a physical store, online, or through other channels.

Cloud computing is the on-demand availability of computer system resources, in particular data storage and computing power, without direct active management by the user.

The conversion rate is the number of conversions divided by the total number of visitors.

Coordinated Progressive Signals are deployed in urban areas with busy traffic conditions. Several intersection signals will be operated through coordination and hence a constant flow of traffic is maintained.

Coordinated Traffic Adaptive Signals are deployed in streets with rapid demand shifts. Actuated signals will identify the approaches with peak demand and adjust the signal timings. Coordination of signals helps with management of traffic demand.
