In a first aspect, a method for optimizing efficiency of a transport provider is provided, comprising: receiving, by a processor, a first departure time of a vehicle, which is administered by the transport provider, at a first location; receiving, by the processor, a second departure time of the vehicle at a second location which is located after the first location; determining, by the processor, a difference between the first departure time and the second departure time; and updating, by the processer, a current schedule to provide an updated schedule in response to the determination of the difference, the updated schedule indicating an updated estimated arrival time of the vehicle at a location after the second location.

A method for executing or adapting a forwarding strategy in a vehicular ad-hoc network (VANET) includes performing, by a first vehicle being a node in the VANET, the following actions: analyzing current environmental conditions; creating a forwarding strategy based on the current environmental conditions; and forwarding information to other vehicles in the VANET according to the created forwarding strategy.

A method for providing configuration information for a system having a plurality of vehicles includes assigning, for each vehicle, a first number of degrees of freedom (DOF); presetting one or more system parameters representing a performance of at least part of the system (SP); successively optimizing each respective vehicle at each station by selecting a DOF for each vehicle from a second number of DOF for the respective vehicle and computing a global SP; assigning each vehicle of each station a DOF resulting from a first system configuration (SC); evaluating the global SP for the first SC; identifying one or more stations having a negative impact (NIS) on the global SP on the first SC; and successively optimizing, for the one or more NIS, each vehicle locally at each respective NIS with regard to the SP with a number of DOF greater than said second number of DOF.

A method for continuous processing of two-level data on a system with a plurality of nodes for processing the data includes determining a system state representing at least one of actual or possible performance capabilities of the system, determining already processed data on the nodes, splitting and assigning high-level input data for processing with lower level data on one or more of the plurality of nodes according to the determined system state, processing requirements of the data and already processed data in a form of at least of lower level data on the nodes such that in case of the already processed data, data to be processed is compared with the already processed data, and input data is split and assigned to the plurality of nodes such that an amount of data to be exchanged for processing the input data on the respective nodes is minimized.

A method for providing a demand-responsive transportation system includes receiving mobility trace data of collaborative individuals. Clusters of individuals are generated and mobility-activity models for the clusters are defined. Non-collaborative individuals are assigned to the clusters using a combinatorial optimization problem. An Origin-Destination (OD) demand is determined from the clusters. Non-collaborative individuals are re-allocated to different ones of the clusters using an approximation function that learns from an observed OD and the mobility trace data. The mobility-activity models are trained based on the re-allocation of the non-collaborative individuals to different ones of the clusters. An OD database (OD-DB) is maintained to be queried with a geographic location and time so as to receive information from the OD-DB about the current OD demand for the geographic location and time. Control actions are issued to vehicles in a fleet of the transportation system based thereon.

A method for information dissemination in a multi-technology communication network wherein network nodes are equipped with first communication means for operating via a long range communication network and with second communication means for performing short-range communication includes performing, by a central entity, the steps of determining coverage areas of the network nodes; establishing dissimilarity relations between network nodes with respect to the coverage areas of the network nodes such that a dissimilarity relation index value is larger for two network nodes covering less similar areas; and selecting, subject to configurable constraints, network nodes with a highest dissimilarity relation index value as mobile infrastructure nodes that are intended to act as relay and/or forwarder nodes for supporting optimal information penetration in a given destination dissemination area.
