A traffic management method, for managing traffic of a transportation network, the method comprising the steps of: - by means of a traffic manager, managing the traffic and the transportation network, according to a basis instruction timetable, by sending orders to said traffic and to said transportation network, the traffic manager being configured to manage the traffic by sending said orders through suitable communication means, the traffic manager being configured to obtain and store data relating to the transportation network and to the traffic through said communication means. - automatically detecting and/or predicting at least one conflict in the traffic, - generating a conflict solution in knowledge of the conflict, and - managing the traffic and the transportation network with a modified instruction timetable based on the generated conflict solution, wherein the step of generating the conflict solution comprises at least the sub-steps of: - automatically splitting the transportation network into: ∘ at least one local part, in which the conflict is involved, each local part including an area of the transportation network where one of the conflicts is involved, and ∘ a complementary part distinct from the local part, said complementary part constituting the rest of the transportation network not considered as local part, said local part and complementary part together constituting the whole transportation network, - automatically generating at least one local solution relative only to the local part, - automatically generating at least one complementary solution relative only to the complementary part, the complementary solution being generated in consideration of the local solution, and - automatically combining the local solution with the complementary solution for obtaining the conflict solution. - by means of a traffic manager, managing the traffic and the transportation network, according to a basis instruction timetable, by sending orders to said traffic and to said transportation network, the traffic manager being configured to manage the traffic by sending said orders through suitable communication means, the traffic manager being configured to obtain and store data relating to the transportation network and to the traffic through said communication means. - automatically detecting and/or predicting at least one conflict in the traffic, - generating a conflict solution in knowledge of the conflict, and - managing the traffic and the transportation network with a modified instruction timetable based on the generated conflict solution, - automatically splitting the transportation network into: ∘ at least one local part, in which the conflict is involved, each local part including an area of the transportation network where one of the conflicts is involved, and ∘ a complementary part distinct from the local part, said complementary part constituting the rest of the transportation network not considered as local part, said local part and complementary part together constituting the whole transportation network, ∘ at least one local part, in which the conflict is involved, each local part including an area of the transportation network where one of the conflicts is involved, and ∘ a complementary part distinct from the local part, said complementary part constituting the rest of the transportation network not considered as local part, said local part and complementary part together constituting the whole transportation network, - automatically generating at least one local solution relative only to the local part, - automatically generating at least one complementary solution relative only to the complementary part, the complementary solution being generated in consideration of the local solution, and - automatically combining the local solution with the complementary solution for obtaining the conflict solution.
