摘要： The present disclosed subject matter relates to a method of controlling event-responsive traffic lights at an intersection of lanes by a controller which switches the traffic lights in a sequence of phases. The controller has a memory storing a set of phase sequences and is configured to change from one phase sequence to another. The method comprises, in a server: a) generating candidate sets of phase sequences; b) determining the traffic flows on the lanes; c) calculating a cost measure for each candidate set; and d) sending the candidate set with the lowest cost measure to the controller; in the controller, receiving and storing the sent set in the memory as the set; and repeating steps b)-d). The disclosed subject matter further relates to the server used in said method.

摘要： A method for determining a lateral position of a vehicle passing a road and carrying a transponder uses at least two antennas mounted at different lateral positions and connected to a processor and comprises: triggering the transponder and recording signals from responses of the transponder by the processor, each signal being received via one of the antennas and recorded as i) a time of receipt at said one antenna and ii) the lateral position of said one antenna; generating by the processor a regression curve fitting all recorded signals; and determining by the processor the lateral position of the vehicle from the generated regression curve. An apparatus implementing said method is also disclosed.

摘要： The subject matter disclosed herein relates to a method for checking toll transactions, produced from position notifications of a mobile phone connected via a mobile network to a transaction server, with the aid of a network of distributed toll beacons, which can communicate via short-range radio with on-board units of passing vehicles and are connected to the transaction server. To this end, a interoperable multi-functional OBU is created that is formed from a GNSS- and NFC-enabled mobile phone on the one hand and an NFC- and DSRC-enabled OBU on the other hand, which exchange data concerning a session identifier (SID) via their common NFC interface, which session identifier forms a link between the infrastructureless and the infrastructure-bound billing functions of the multi-functional OBU. The disclosed subject matter also relates to a toll beacon and a transaction server for same.

摘要： The present subject matter relates to a method of predicting a traffic behaviour in a road system, comprising the following steps carried out by at least one processor connected to a database, which contains a set of traffic profiles: clustering the traffic profiles; for each cluster, determining a dissimilarity measure; receiving a request having one or more request tags; checking whether all request tags match one of the characteristic vectors of the clusters, and if so, outputting a predicted traffic behaviour, else, eliminating one of the request tags from the request and returning to the beginning of said step of checking.

摘要： The disclosed subject matter relates to an Intelligent Transportation System (ITS) service station, comprising: a receiver configured to receive, from each of a set of ITS stations, a status message which includes the geographical position of the ITS station; a controller connected to the receiver and configured to determine, on the basis of the received geographical positions, whether a subset of ITS stations in said set meets a predetermined criterion of mutual proximity; and a transmitter connected to the controller and configured to transmit, when said subset comprises two or more ITS stations, a service message indicative of the subset to the ITS stations of said subset. The disclosed subject matter further relates to an ITS station receiving a service message.

摘要： A method for encrypted communication in an ad-hoc network having a plurality of network nodes comprises the following steps performed in a first node of the network: receiving an initiation message from a second node of the network, the received initiation message comprising a public key of said second node; determining at least one of a proximity or velocity measure of said second node; checking whether the at least one determined measure is below a threshold and, if so, emitting a reply message comprising an encrypted part and an encryption key encrypted with the received public key from said second node; and repeatedly emitting status messages, wherein at least a part of each emitted status message is encrypted with the encryption key.

摘要： The disclosed subject-matter relates to a method for calibrating an onboard unit of a vehicle identification system, the method comprising: emitting at least one polling message from a first radio beacon; in the first radio beacon, determining a link margin of a communication with a first onboard unit by evaluating a response message of the first onboard unit to the polling message(s); and sending a configuration message from the first radio beacon or a second radio beacon to the first onboard unit or to a second onboard unit with a same characteristic as the first onboard unit to adjust a receive sensitivity or a transmit power of the first or the second onboard unit, respectively, to a level derived from the determined link margin. Alternative embodiments relate to a system and to an onboard unit used in the method.

摘要： System and method for verification and/or reconciliation of electronic transactions, such as for example, toll transactions or other purchase transactions. A vehicle utilizes an onboard communication device, such as a mobile phone, to locate virtual tolling points using GPS location, and then to communicate to an electronic tolling service provider that the vehicle has passed through the virtual tolling point. In addition, roadside equipment may be used to capture photo/video of the vehicle as it passes the virtual tolling point. The GPS-based toll transaction data is used in conjunction with the photo-based toll transaction data to verify a proper toll transaction, and optionally to reconcile between missing and/or inconsistent GPS-based and photo-based toll transaction data.

摘要： The present subject matter relates to a method and a roadside unit for generating a digital record of a vehicle in a road toll system, comprising: capturing an image of the vehicle on a roadway; data-compressing the image depending on at least one of a confidence level obtained from the image for one or more characters therein by means of OCR, and a contrast parameter obtained from the image or a region of interest therein or a section of the latter, to generate the digital record; and sending the digital record from the roadside unit to a data center of the road toll system.
