The optimization model of transport routes taking into account the state of roads and road traffic congestions

The paper refers to the transport logistics optimization problem solving taking into account the roads state and road traffic congestions. The logistics acts as the hidden resource providing the companies competitive advantage. The investigated papers claim that the route of freight delivery is estimated by the distance passed by a vehicle, but the set of other factors influencing delivery time isn't considered. For the purpose of taking note of these factors the authors have introduced new concepts, have developed the mathematical model allowing to optimize the organization of freight delivery taking into account distance, the probable speed of the vehicle depending on the road quality, transport stream intensity, weather conditions.
