A Model for Design and Development of Stable Transportation Networks Using Genetic Algorithm

Transportation networks that are subject to daily hazards, such as traffic accidents, a rainfall, as well as damage related to natural disasters, such as floods and earthquakes, are therefore considered vulnerable. Different parameters, for example network capacity and shape alongside the vulnerability of network components, affect the network stability. Among these parameters, a form of network that can be stable for a large number of conditions is of particular interest.In this article, the effect of different indices on network topology will be studied and using genetic algorithms, a method for solving the problem of network topology design based on travel time, efficiency and stability indices will be introduced. For the purpose of network development, the effect of various network performance indices on the design of a network will be examined, and finally the results from using these indices alongside travel time index in the design of network will be compared. The findings show that network design based on travel time index is unable to yield a reliable network for traffic incidents in the long term, and network design based on reliability and travel time index yield a different network.
