Center to center (C2C) communication involves peer-to-peer communications between computers involved in information exchange in real-time transportation management in a many-to-many network. This type of communication is similar to the Internet, in that any center can request information from, or provide information to, any number of other centers.
One heuristic proceeds incrementally. The traffic to be assigned is divided into parts (usually 4). Assign the first part of the traffic. Compute new travel times and assign the next part of the traffic. The last step is repeated until all the traffic is assigned. The CATS used a variation on this; it assigned row by row in the O-D table.
[6] [7] [8] When all approaches to an intersection are controlled in this way the rules for an all-way stop apply. Traffic signals may also flash yellow to major directions and flash red to minor directions during off-peak times to minimize traffic delays, in which case only side-street traffic is required to stop and yield the right of way to ...
Three-phase traffic theory is a theory of traffic flow developed by Boris Kerner between 1996 and 2002. [1] [2] [3] It focuses mainly on the explanation of the physics of traffic breakdown and resulting congested traffic on highways.
It is suggested that an alternate approach could involve traffic calming, and a conceptual focus on the movement of people and goods rather than vehicles. It can be argued that Traffic optimization inherently calms traffic due to discouraging speeding and limits acceleration and deceleration thus reducing the noise pollution produced by vehicles.
The situational theory of problem solving attempts to explain why and how an individual communicates during a problematic situation. The situational theory of problem solving (STOPS) was proposed by Jeong-Nam Kim and James E. Grunig in 2011 though their article “problem solving and communicative action: A situational theory of problem solving.”
In 1993, the communication scholars Denis McQuail and Sven Windahl referred to Lasswell's model as "perhaps the most famous single phrase in communication research." [ 18 ] McQuail and Windahl also considered the model as a formula that would be transformed into a model once boxes were drawn around each element and arrows connected the elements.
A common objection is based on the fact that it is a linear transmission model: it conceptualizes communication as a one-way process going from a source to a destination. Against this approach, it is argued that communication is usually more interactive with messages and feedback going back and forth between the participants.
