Traffic flow. In 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 ...
A junction for road vehicles and pedestrians controlled by traffic lights in the UK. The various vehicle and pedestrian movements are separated in either time or space for safety and efficiency. The normal function of traffic lights requires more than sight control and coordination to ensure that traffic and pedestrians move as smoothly, and ...
Traffic optimization is the methods by which time stopped in road traffic (particularly, at traffic signals) is reduced. Need for traffic optimization [ edit ] Texas Transportation Institute estimates travel delays of between 17–55 hours of delay per person per year relating to congestion on the streets. [1]
Interstellar travel is the hypothetical travel of spacecraft from one star system, solitary star, or planetary system to another. Interstellar travel is expected to prove much more difficult than interplanetary spaceflight due to the vast difference in the scale of the involved distances. Whereas the distance between any two planets in the ...
The estimated one-way travel time from DART's Shiloh Road station to the DFW Airport/Terminal B station is 60 minutes (and 59 minutes in the opposite direction). These run times include station dwell times of 30 seconds at all stations except for Downtown Carrollton, Addison Transit Center, CityLine/Bush, and 12th Street, where dwell times are ...

Route assignment. Route assignment, route choice, or traffic assignment concerns the selection of routes (alternatively called paths) between origins and destinations in transportation networks. It is the fourth step in the conventional transportation forecasting model, following trip generation, trip distribution, and mode choice.
The fundamental diagram of traffic flow is a diagram that gives a relation between road traffic flux (vehicles/hour) and the traffic density (vehicles/km). A macroscopic traffic model involving traffic flux, traffic density and velocity forms the basis of the fundamental diagram. It can be used to predict the capability of a road system, or its ...
