Implicit limiting factors in postal network development of pre-soviet Siberia

Development of informational network in time and space is restrained by several factors. Usually they are described as institutional and communication barriers without exact geographical localization. The case study of development of a postal network of Siberia in 1782–1916 shows that implicit internal factors constraining postal network development may be linked to individual settlements, and the list of such factors is considerably expanded. For the first time filters and traps of postal network development are revealed. For four types of traps the negative impact on a postal network is calculated, measured as number of the settlements which had entered into a network time-lagged or haven’t entered at all.
