WebDynamic Traffic Assignment¶ Traffic assignment is the process that determines how the traffic demand – usually defined in terms of an origin-destination matrix – is loaded onto … WebThe dynamic nature of traffic networks is manifested inboth temporal and spatial changes in traffic demand, roadwaycapacities, and traffic control settings. Typically, theunderlying network traffic demand builds up over time at theonset of a peak period, varies stochastically during thepeak period, and decays at the conclusion of the peak period.
