Computing cost optimal paths in network data is a very important task in many application areas like transportation networks, computer networks or social graphs. In many cases, the cost of an edge can be described by various cost criteria. For example, in a road network possible cost criteria are distance, time, ascent, energy consumption or toll fees. In such a multicriteria network, a route o...

The real challenge of creating believable and enjoyable board game arti cial opponents lies no longer in analysing millions of moves per minute. Instead, it lies in creating opponents that are socially aware of their surroundings and that can interact socially with other players. In traditional board games, where face-to-face interactions, social actions and strategic reasoning are important co...

Traffic noise (and in more detail rolling noise) affects the health of thousands of citizens. Consequently a number of silent technologies (quiet surfaces) are available, with different weaknesses, noise performance, and expected life. This notwithstanding, addressing noise impacts from a Life cycle cost analysis (LCCA) perspective is still an issue. Indeed, characterization factors, inventory ...

To support the evaluation of dynamic road pricing strategies in a network context, this study develops a bi-criterion dynamic user equilibrium (BDUE) model, which aims to capture users’ path choices in response to time-varying toll charges, and hence explicitly considers heterogeneous users with different value of time (VOT) preferences in the underlying path choice decision framework. The VOT ...

This paper develops a comprehensive framework for analysing and calculating user equilibrium, system optimum, and externalities in time-dependent road networks. Under dynamic user equilibrium, traffic is assigned such that for each origin-destination pair in the network, the individual travel costs experienced by each traveller, no matter which combination of travel route and departure time he/...

The potential effectiveness of vehicle-based secondary safety systems for the protection of pedestrians and pedal cyclists is related to the proportion of cases where injury arises by contact with the road or ground rather than with the striking vehicle. A detailed case review of 205 accidents from the UK On-the-Spot study involving vulnerable road users with head injuries or impacts indicated ...

We study a class of noncooperative general topology networks shared byN users. Each user has a given flow which it has to ship from a source to a destination. We consider a class of polynomial link cost functions, adopted originally in the context of road traffic modeling, and show that these costs have appealing properties that lead to predictable and efficient network flows. In particular, we...

Deterministic traffic assignment is based on the assumption that each user is perfectly informed about the topology of the network and the costs that he would incur by travelling on any road arc. In this context, as a rational decision maker he will choose to travel on a shortest path, i.e. one among the paths connecting on the network his origin to his destination with the least cost. Any cong...
