Unlike the shortest path is randomly chosen in the traditional shortest path routing strategy, a novel routing strategy to improve the network transportation capacity is proposed in this paper. According to the different characteristics of the nodes along actual paths, we specify the shortest paths of all pairs of nodes aiming at reducing the betweenness of those high-betweenness nodes. Simulat...

To realise an autonomous control for transport networks it is attempted to transfer well known and approved routing protocols from data communication to transport problems. Here structural differences between data and transportation networks prevent a direct transfer of the protocols. In transportation networks not one but several diverse and particularly adapted protocols are needed, which hav...

We consider algorithms for finding the optimal location of a simple transportation device, that we call a moving walkway, consisting of a pair of points in the plane between which the travel speed is high. More specifically, one can travel from one endpoint of the walkway to the other at speed v > 1, but can only travel at unit speed between any other pair of points. The travel time between any...

Emissions resulted from transportation activities may lead to dangerous effects on the whole environment and human health. According to sustainability principles, in recent years researchers attempt to consider the environmental burden of logistics activities in traditional logistics problems such as vehicle routing problems (VRPs). The pollution-routing problem (PRP) is an extension of the VRP...

In this paper, a new approach to risk minimizing vehicle routing and scheduling problem is presented. Forwarding agents or companies have two main concerns for the collection of high-risk commodities like cash or valuable commodities between the central depot and the customers: one; because of the high value of the commodities transported, the risk of ambush and robbery are very high. Two; the ...

The increasing use of electric vehicles in road and air transportation, especially last-mile delivery city mobility, raises new operational challenges due to the limited capacity batteries. These limitations impose additional driving range constraints when optimizing distribution mobility plans. During last years, several researchers from Computer Science, Artificial Intelligence, Operations Re...
