Mathematical Model of the Traffic Problems
Abstract: The establishment of a common transport problems first mathematical differential model , and then the traffic light model as an example to conduct in-depth research and analysis of the strengths and limitations of the differential model of traffic flow , and finally the actual traffic environment , the establishment of a cellular automaton model ,the variation of the movement of vehicles on the road into the evolution of cellular automata rules , establish traffic flow model of cellular automata theory. Under the provisions of cellular parameters such as length and maximum speed, situations presented reflect road vehicles automata rules on freedom of travel and slow down other traffic behavior.
Key words: Traffic flow model; Differential equations; Cellular Automata
