Definitions

  • the invention relates to a portable roadside traffic information output apparatus, comprising an output means for outputting traffic information, a configuration apparatus for generating data for configuration of a portable roadside traffic information output apparatus, a computer program product forming a configuration apparatus, a system comprising a portable roadside traffic information output apparatus and a configuration apparatus, a method for outputting traffic information by use of a portable roadside traffic information output apparatus, an onboard apparatus for receiving traffic information sent by a portable roadside traffic information output apparatus, a computer program product forming an onboard apparatus, and a system comprising a portable roadside traffic information output apparatus and an onboard apparatus.
  • the road sign shown in this prior art consists of a capsule with a buffer material. Within the capsule, an antenna and a microchip are placed. The microchip receives an excitation radio wave from vehicles passing by through the antenna, converts the excitation radio wave into electric power, and sends radio information stored in it to the travelling vehicle using the antenna.
  • the capsule is adapted to be buried into a road.
  • the electronic road sign disclosed in JP 7 334 789 has significant disadvantages, especially if it is necessary to alert drivers of vehicles to construction work that is carried out on the road ahead. Since the road sign is buried in the road, its relocation is very difficult. Furthermore, it is adapted to always send the same traffic information. Since the position of the construction work on the road is frequently changed according to the progress of the road works, it becomes necessary to install new electronic road signs.
  • Another electronic road sign is disclosed in US 2004/0178927 A1 .
  • This electronic road sign is installed close to a normal road sign, wherein the electronic road sign transmits a road warning having a preset relevant road direction in order to allow passing by vehicles to determine whether the received road warning is relevant for them based on their travelling direction.
  • this road sign has the disadvantage that the traffic information being output is preinstalled in the electronic road sign. Furthermore, relocating the electronic road sign is difficult. Therefore, this electronic road sign is unsuitable to be used to output warnings that alert drivers of vehicles to construction work due to the dynamics of the location of the construction work.
  • EP 1229508 A1 discloses a system comprising fixed radio beacons (TX-F), mobile and portable radio beacons (TX-M), together with vehicle receiver units (RX-M) and/or receiver units (RC-P) carried by pedestrians for all types of warning and assistance messages, or both or either with mobile transceivers (TX/RX-M) for motorcars and other transceivers (TX/RX-P) for pedestrians, the latter for transmitting and receiving similar warning and assistance messages, all being controlled by an operation centre (CO) and which has a services network, with elements which are fixed, mobile, or portable.
  • TX-F fixed radio beacons
  • TX-M mobile and portable radio beacons
  • RX-M vehicle receiver units
  • RX-P receiver units
  • a portable roadside traffic information output apparatus having the features of claim 1, a system having the features of claim 11, a method for outputting traffic information by use of a portable roadside traffic information output apparatus having the features of claim 14, and/or a computer program product having the features of claim 15.
  • a portable roadside traffic information output apparatus comprising output means for outputting traffic information.
  • This portable roadside traffic information output apparatus further comprises receiving means for receiving data for configuration of the portable roadside traffic information output apparatus with regard to the traffic information to be output and control means for controlling the output means.
  • the control means controls the output means according to the received data.
  • Such an apparatus has the advantage that it is able to receive data for control of the apparatus from the external, so that the operation of the apparatus and the data that is output can be controlled and determined. Furthermore, since the apparatus is portable, it can be easily relocated.
  • Portable in the sense of the invention means that the apparatus can be positioned by a single human being at different arbitrarily chosen locations and can be set to another location, i.e. it can be relocated.
  • the weight of the apparatus is below 30 kg, preferably below 10 kg.
  • roadside in the sense of the invention means that the apparatus is used on or near the road, street, highway, or the like.
  • the data that is received by the receiving means of the portable roadside traffic information output apparatus comprises traffic data to be output by the output means and configuration data for controlling the operation of the portable roadside traffic information output apparatus.
  • This offers the advantage that the data output by the apparatus can be determined via the receiving means.
  • it is possible to control the operation of the output apparatus by sending configuration data. For example, it can be determined how often the data is output, in what frequency it is output, when the outputting starts and ends, and so forth.
  • the portable roadside traffic information output apparatus further comprises a switch being operable by a user for activating the operation phase of the portable roadside traffic information output apparatus.
  • the control means controls the output means according to the state of the switch. For example, in many scenarios, in which the portable roadside traffic information output apparatus is used to warn vehicle drivers against a construction site being ahead, the construction workers want to configure the portable roadside traffic information output apparatus at a certain location where only the configuration takes place, but where the apparatus should not start outputting traffic information, yet. After the configuration the configured apparatus is taken to the location where it is deployed. The construction worker turns on a switch and the apparatus starts outputting traffic information.
  • the described switch is a simple, but effective measure to allow the separation of the configuration phase from the operation phase. This means that the portable roadside traffic information output apparatus may be configured at one location and may be deployed at another location, wherein the start of the operation phase may be easily controlled by a single switch that is part of the portable roadside traffic information output apparatus.
  • the output means of the portable roadside traffic information output apparatus comprises an antenna element.
  • the antenna element is configured to send radio signals in order to transmit traffic information.
  • the receiving means comprises an antenna element. Due to this antenna element, the receiving means may receive data from the external, even after its installation at the road.
  • Other conceivable embodiments of the receiving means may be wirebound interfaces using, for example, USB-ports or any other connector technology.
  • the antenna element of the receiving means is constituted by the antenna element of the output means.
  • the output means and the receiving means use the same antenna element.
  • the output means and/or the receiving means are configured to operate based on the protocol Dedicated Short Range Communication (DSRC) or IEEE 802.11p.
  • DSRC is a radio technology that was especially developed to be used in Vehicular Ad-hoc NETworks (VANETs).
  • VANETs Vehicular Ad-hoc NETworks
  • IEEE 802.11p was developed for use cases in the area of vehicle-to-vehicle communication.
  • One advantage of these two protocols and radio technologies is that they can transmit communication packets up to hundreds of metres, which makes them suitable for vehicle-to-vehicle communication.
  • the output means of the portable roadside traffic information output apparatus comprises a warning output means for outputting traffic warnings.
  • a warning output means for outputting traffic warnings. This allows the apparatus to output traffic warnings that may be received by nearby vehicles such that the driver of the vehicle may be warned of a potentially dangerous zone ahead.
  • the output means preferably also comprises a location information output means for outputting location information being related to traffic information.
  • a location information output means for outputting location information being related to traffic information.
  • the control means of the portable roadside traffic information output apparatus comprises a means for controlling a start time of the operation of the output means and/or a means for controlling an end time of the operation of the output means.
  • the portable roadside traffic information output apparatuses may be positioned at suitable positions without being configured, but with the switch for activating the operation phase being turned on.
  • a nearby configuration apparatus may send data comprising traffic data to be output and configuration data containing instructions when the outputting of the traffic data should start and when it should end. In other words, an advantageous combination of the positioning phase, the configuration phase, and the operation phase becomes possible.
  • the portable roadside traffic information output apparatus may further comprise a signal means for signalling that the received data is correct.
  • the apparatus may be configured, a construction worker can verify whether the apparatus is correctly configured by looking at the signal means, based on the signal he can decide whether he needs to configure the apparatus again or if he may take the apparatus to a place where it is deployed and after having brought the apparatus to its deployment position, he may start the operation phase by turning on a switch that is part of the apparatus.
  • the portable roadside traffic information output apparatus further comprises a location determination means.
  • a location determination means may be, for example, a GPS receiver. Based on this location determination means, the apparatus can determine where it is deployed. The location information may be given to vehicles passing by or it may be given to a configuration apparatus, so that the location of the portable roadside traffic information output apparatus may be taken into account when new configuration data is generated.
  • the invention also comprises a configuration apparatus for generating data for configuration of a portable roadside traffic information output apparatus with regard to the traffic information to be output and for sending the generated data to the receiving means of a portable roadside traffic information output apparatus.
  • the configuration apparatus has the advantage that it allows the generation of data by, for example, inputting the traffic information to be output and inputting parameters that control the operation of the portable roadside traffic information output apparatus and then sending the generated data to the receiving means of the portable roadside traffic information output apparatus. With the help of this configuration apparatus the roadside traffic information output apparatus may be configured in a convenient way.
  • the configuration apparatus is an onboard device that is mountable in or on a vehicle.
  • This embodiment has two advantages: The first advantage is that the configuration apparatus may be a part of a construction work vehicle that is used for the construction work. Therefore, when the construction site moves according to the progress of the construction work, the driver of the construction work vehicle may easily reconfigure the portable roadside traffic information output apparatuses. Furthermore, by combining a vehicle and the configuration apparatus, legal problems may be circumvented.
  • the communication protocols DSRC or IEEE 802.11p are used. In most countries, the respective frequencies on which the radio signals are transmitted by DSRC or IEEE 802.11p are reserved exclusively for vehicle-to-vehicle communication. If the configuration apparatus were a standalone apparatus not being combined with a vehicle, questions would arise whether the sending of data from the configuration apparatus to the portable roadside traffic information output apparatus is allowed according to the law.
  • the configuration apparatus further comprises a location determination means.
  • This location determination means may be, for example, a GPS receiver.
  • the user of the configuration apparatus may easily generate traffic information that contains accurate information about the position of the construction site.
  • a configuration apparatus as described above may be formed on a generic computing device by running a suitable configuration software on it.

In this way, the receiving of data is repeated until correct data is received. A construction worker can easily see that the receiving of data has been successfully completed by looking at the signal means. When the signal means signals that the received data is correct, the construction worker may take the portable roadside traffic information output apparatus to a suitable position near the road and may activate its operation phase.
  • the step of outputting traffic information further comprises the steps of outputting a message containing traffic information, waiting for a predetermined time period, and returning to the step of outputting a message containing traffic information.
  • the outputting of traffic information is periodically repeated.
  • the frequency of the outputting may be controlled.
