Simulation Processes of Construction of Optimal Routes for the Delivery of Goods by Road Transport on Urban Road Network in Mountainous Cities

Abstract

A method of optimization of cargo delivery routes in the conditions of non-stationary dynamics of traffic flows on the urban road network sections for cities located in mountainous areas is proposed. In doing so, the emergence of such non-stationary states is due to the influence of natural factors on the structural characteristics of the urban road network (seismically-active influences, floods, mudflows, landslides, etc.). The method is based on the use of a modified ant algorithm. In the frameworks of the proposed method, a test simulation is carried out for the mountainous city of Quito, the capital of Ecuador. The obtained results of the research point to the prospect of application of the proposed method for finding the optimal routes for the delivery of goods, taking into account the specifics of the road network of cities, within which transportation is carried out.
