Ramp Metering controls the rate at which vehicles enter highways by using traffic signals at on-ramps, optimizing the merge process. Its application reduces freeway congestion and improves safety.

Roundabouts are a circular intersection design that enables continuous flow of traffic in one direction around a central island. Its application reduces the likelihood and severity of collisions compared to traditional intersections.

Signal Timing refers to the programming of traffic lights to manage vehicle and pedestrian flows. Its application includes optimizing the duration of green, yellow, and red intervals to minimize delays and improve intersection safety.

Intelligent Transportation Systems apply technology solutions, like real-time traffic information and adaptive signal control, to enhance transportation efficiency and safety. Its application can be seen in smart traffic management and information systems.

Trip Generation is the estimation of the number of trips originating or ending in a particular area. Its application is integral in transportation planning and forecasting traffic volumes for future developments.

Traffic Calming employs physical design and other measures to reduce vehicle speeds and enhance safety for pedestrians and cyclists. Its application can be seen in residential neighborhoods and high-pedestrian areas.

A Road Diet involves reducing the number of lanes on a roadway to improve safety and provide space for other modes of transportation. Its application is commonly seen in urban planning for traffic calming and to accommodate bicyclists and pedestrians.

Traffic Flow is the study of the movement of individual drivers and vehicles between points in a traffic network, often represented using mathematical models. Its application can help in planning road layouts and managing congestion.

Traffic Demand Management encompasses strategies to reduce congestion by altering travel behavior. Its application involves encouraging carpooling, public transit, and flexible work hours to decrease peak demand.

Queueing Theory studies the behavior of queues to predict traffic congestion and waiting times. Its application in transportation helps in designing toll plazas and intersections to minimize delay.

Level of Service is a qualitative measure describing operational conditions within a traffic stream. Its application ranges from assessment at signalized intersections to freeway segments, aiding in infrastructure enhancement decisions.

Traffic Impact Analysis studies the effects of proposed developments on the transportation network. Its application aids in understanding future traffic conditions and necessary improvements.

Traffic Signal Preemption is a mechanism that allows the normal operation of traffic lights to be overridden, commonly for emergency vehicles. Its application ensures rapid and safe passage for these vehicles through intersections.

A Pedestrian Scramble is a pedestrian-only phase in traffic signal operations where all vehicular traffic is stopped, allowing pedestrians to cross in every direction, including diagonally. Its application improves pedestrian safety and mobility in high-traffic areas.

Traffic Modeling uses mathematical and simulation models to represent traffic flows and test the impact of changes. Its application assists in decision-making for road network design and traffic management strategies.

Vehicle Detection Systems are used to identify and count vehicles passing or arriving at a certain point, typically using sensors. Its application includes optimizing signal timing and measuring traffic volumes.

Origin-Destination Study collects data to determine the significant starting points and destinations of trips in a study area. Its application helps in identifying travel patterns to support infrastructure planning and transport modeling.

Congestion Pricing is a strategy that involves varying toll prices based on traffic demand to reduce road congestion. Its application deters peak travel times and encourages the use of alternative transportation modes.

Intersection Sight Distance is the required line of sight needed by a driver to safely enter or cross an intersection. Its application ensures road designs permit adequate visibility for traffic safety.
