Transit Signal Priority (TSP) or Bus priority is a operational measure to reduce dwell time at traffic signals for transit vehicles by holding green lights longer or shortening red lights.

Target Take Off Time (TTOT) is the Target Take Off Time taking into account the TOBT/TSAT plus the EXOT. Each TTOT on one runway is separated from other TTOT or TLDT to represent vortex and/or SID separation between aircraft

In the context of video analytics and access control systems, tailgating detection involves using advanced cameras and sensors to monitor access points, ensuring that only one person enters for each valid credential presented.

Tailgating, also referred to as Piggybacking, in Physical Security is a form of unauthorized access caused by unauthorized person following a authorized person or group of authorized persons through a access control.

Tailgating in Traffic is an action in which the minimum distance to the car in front is not kept.

Tampering Detection is a video analytics function which recognizes when a device such as a security camera is being manipulated.

Taxi Time is the total time an airplane spends in taxi (movement on the airport) before take-off and after landing, i.e the sum of Taxi-In Time and Taxi-Out Time.

The Taxi-In time is computed as the duration between landing (wheels on) time and gate in time, as reported by carriers. A system value is obtained by averaging these durations over a period of time.

The Taxi-Out Time is computed as the duration between gate out time and take off (wheels off) time. A system value is obtained by averaging these durations over a period of time.

Tenant management refers to the administration and oversight of rental properties like property management.

A thermal camera (also called infrared camera) is a camera that creates an image using infrared (IR) radiation. The created image represents the temperature of the object.

Threat Detection is a video analytics function which automatically detects potential threads such as running people, abnormal crowd movement or intrusion.

evenue sharing divides the income fairly based on predefined agreements, while allocation determines each party’s share using factors like usage, distance, or contributions. It ensures transparency, fair compensation, and collaboration among operators, event organizers, or service providers.

Time Gap is a measure of the time that elapses between the departure of the first vehicle and the arrival of the second at the designated test point.

A Time of Flight (ToF) sensor is an optical sensor used to measure distance, velocity, and other related measurements. Various type of signals can be used to build ToF sensors, but typically either light or sound are used as carrier signal.

A traffic camera is a type of camera that is used to monitor vehicular traffic on roads and highways.

Traffic Congestion is a traffic phenomena characterized by slower vehicle speeds, longer trip times and increased queuing of vehicles.

A traffic counter is a device that measures road traffic passing the counter. Traffic counters can be realized with different technologies such as radar, lidar, WiFi or security cameras.

Density refers to the number of vehicles present on a given length of roadway. Density is reported in terms of vehicles per mile or vehicles per kilometer. High densities indicate that individual vehicles are very close together.

Traffic detectors are a critical part of any intelligent transportation system. They collect data about the current traffic conditions so that transportation management and operations decisions can be made.

Traffic Impact Analysis (TIA) is a a specific study determining the overall potential impact of a traffic generator.

A traffic signal control system uses automated lights to optimize traffic flow and safety in real-time.

Traffic Signal Coordination is the linking of consecutive traffic signals along a road to minimize congestion and enable free flow.

There are four different traffic signal types: Uncoordinated Fixed Time Signals, Uncoordinated Traffic Actuated Signals, Coordinated Progressive Signals and Coordinated Traffic Adaptive Signals.

A traffic study, also known as a transportation study or traffic analysis, is a systematic examination of traffic conditions, patterns, and behaviors within a specific area. It involves collecting and analyzing data to gain insights into traffic flow
