  • vehicle detector means for by visible or invisible light detecting a vehicle while passing therealong
  • communication means for through communicating between the registration system and the vehicle effecting a registration of that vehicle.
  • invisible light could be a radar beam.
  • Detection checking the actual presence of a particular vehicle at such position that the same or another camera can subsequently make a useful, in particular, a sharp picture of that vehicle.
  • Registration making pictures of both front side and rear side of a vehicle with the purpose of checking the identity of the vehicle with respect to legal or other requirements.
  • Tracking in such manner following the location of a vehicle in time so as to allow matching and/or correlating the detection-registration of the front side with the detection-registration of the rear side of the vehicle in question.
  • Classification checking the class of a particular vehicle (such as motorcycle, passenger car or van) through an extension of the detection system.
  • road toll collection is O 97/50067 PCMB97/00618
  • the toll amount is non-uniform for various types of vehicle - the system must check slow as well as very fast vehicles
  • the vehicles should remain anonymous viz a viz the system, in that after passage and correct payment the system should "forget" the vehicle in question
  • the toll amount can be levied beforehand, in that users pay an amount to an appropriate authority, which is then credited to a vehicle-borne device in the manner of an electronic purse.
  • a communication dialog will verify the amount to be paid versus the amount present in the electronic purse. If the latter allows subtraction of the toll amount, such will then be effected; this may be done with the vehicle remaining anonymous viz a viz the system. If the amount is not sufficient however, or the electronic purse facility is absent, the vehicle's identity has to be registrated by the system to enable its administration authority to then bill the actual user of the road, or another entity responsible for such using.
  • the toll amount can be levied afterwards, in which case the organization is similar to the one effected with the user who was not or not sufficiently authorized: in such case, all vehicles are registrated.
  • the financial aspects may of course be totally different; however, the four primitives listed supra have generally corresponding functionality, if present.
  • various pictures may be taken of the vehicle at different instances in time, which would represent a cause of further uncertainty in the correlation thereamongst.
  • the invention having recognized that the motion of the vehicle through the detection area could cause such uncertainty, in particular because lateral motion may occur, should be able to match various registrations of a particular vehicle to its effective identification.
  • the invention is characterized in that for use with a multilane system, said detector means are multiple and gantry-mounted and are arranged for through successive triggers detecting sequential locations of a particular vehicle for as based thereon correlating multiple registrations of that vehicle as present on multiple positions that are spaced in time and at those multiple positions viewing the vehicle from respective different angles.
  • the light may be visible or near infrared.
  • the identification for example by video storage of the vehicle's license plate, can be effected afterwards, conditional to the need proper for the registration.
  • Another procedure is that all license plates are recorded provisionally, but are retained only if the information must be used further, such as for afterbilling, but cancelled otherwise. Through looking at the vehicle from different angles, additional checks can be effected.
  • the system has tracking means for tracking a vehicle through a change-of-lane when passing the gantry arrangement. Lateral movements are in principle a cause of much uncertainty, for example if various vehicles pass the gantry arrangement quasi-simultaneously. Various other types of mystifications occur, but must be overcome to prove that front side and rear side represent the same vehicle.
  • the detector means allow classifying said vehicle as based on one or more physical size-related properties thereof as a parameter for ascertaining an access right, and actual registration is conditional on matching between said classifying and a predetermined nonconforming outcome of said communicating.
  • toll vehicles It has been customary to toll vehicles according to their size or weight, for example in that motorcycles pay less than passenger cars, which in turn pay less than minivans and so on. Measuring the size of the vehicles, as expressed in one or more of width, height or length can be a useful, and straightforwardly implementable feature of the invention. In this way the posing as another type of vehicle would often fall through. Methods for fraud would be to install an on-board unit of another vehicle class or attaching a wrong tag. ' Advantageously, the system is arranged on viewing both a front license plate and a rear license plate of a vehicle in passage with subsequent verification thereamongst. One type of identification is based on the vehicle's license plate.
  • the invention has recognized that the reading of a single license plate from a predetermined side is often inconclusive, inasmuch as motorcycles often have only a rear license plate, whereas many other vehicles have their rear license plate unreadable through dirt, or obscured by loads carried on the vehicle, or by a trailer. Quite often also, the two plates do not match. It is to be noted that the required fault margins are unbalanced. On the one hand, the chance for a vehicle to pass for a too low toll amount, or even toll-free may be in the range of a few percent. On the other hand, the chance for erroneously imposing toll may not be higher than for example one in ten thousand. The double reading if two license plates are present gives an additional safety margin.
  • the system may have several interactions with the vehicle, in that first an electronic device therein is accessed, and also the license plate and/or shape may be checked.
  • an advantageous arrangement does with only two, or even with only one of such gantries.
  • the cooperation between subsystems on such gantries is of course on a local level, in that the operation of one subsystem is supported or checked by another one. If two gantries are present, the tracking distance is substantially equal to the distance between the two gantries, or larger.
  • the tracking distance may be several times the height of the gantry structure.
  • the latter setup may also be used for measuring overall vehicle behaviour. Particular aspects thereof, such as a slowed speed, excessively frequent change-of-lane could signal actual or impending traffic jams, accident or other. For such case, detecting the license plate would often not be necessary, but colour or shape aspects of a vehicle could help much to correlate its registrations. In such organization, it would often be necessary to do the correlation-based measurement on only a fraction of all vehicles.
  • Various further advantageous aspects are recited in dependent Claims.
  • Figure 1 a flow chart of the system operation
  • Figures 2a, 2b a three-gantry arrangement
  • Figures 6a, 6b a two-gantry arrangement
  • Figure 7, a change-of-lane in the configuration of Figures 6a, 6b;
  • FIGS. 8a, 8b a one-gantry arrangement
  • Figure 1 is an exemplary flow chart of the system operation according to the invention for use with road tolling.
  • the system is set up, tested for correct operation, corrected for such things as environmental light, and finally brought into action.
  • a wake-up signal is produced by the system that wakes up an on-board electronic unit of approaching vehicles, so that an associated wireless dialog can be started as soon as the vehicle is in-range for on the basis of this dialog undertaking the financial aspects of the transaction.
  • the on-board unit may or may not contain an electronic purse.
  • This dialog may imply a mutual verification as to the vehicle's identity or class, and the eventual subtracting of the necessary debit amount that has been prescribed for letting the vehicle type in question pass the tolled route.
  • a waiting loop is expressed that waits for a signal back from the vehicle.
  • the wireless dialog proceeds in a manner that has not been depicted, and in fact is asynchronous with respect to the subsequent stages in the Figure.
  • the dialog may be effected through a transponder, or through an electromagnetic beam in an applicable frequency range.
  • the position of the vehicle is ascertained with respect to an appropriate camera system. If found, in block 28 the front license plate is read, inter alia, with respect to ascertaining the kind of vehicle, such as passenger car, lorry, motorbike, or other.
  • the size of the vehicle is measured, which size in first instance is related to the bounding box of the vehicle as expressed in Cartesian coordinates. One parameter is the width of the vehicle, that may be checked with a granularity of some 10 " 1 meter with video technology or laser radiation.
  • block 32 which may be executed some time later, it is detected whether the vehicle in question is effectively moving to a new traffic lane.
  • the criterion may be that the eventual lateral displacement of the vehicle is extrapolated to more than one half of the sizing granularity. The extrapolation is effected to the vehicle position where the other license plate will be read. If little or no lateral displacement takes place, or need be considered, the system directly goes to block 36. Otherwise, in block 34 the system tracks down the lateral motion of the vehicle, and correlates or matches the positions at respective blocks 28, 36. In block 36, the other license plate is read, and the two numbers are compared. If the two disagree, an alarm procedure is executed, as governed by the check in block 38. In block 40, the size of the vehicle is ascertained once more.
  • block 42 it is ascertained whether the two sizes measured are in agreement with each other, and with the size of the vehicle as associated with the information of tag, on-board unit or license plate. If yes, the data is processed, the financial transfer is effected if applicable, and the system is given free. Various aspects are not given in the Figure, such as the course of action taken when the sizes do not match, or when the license number disagrees with the size. In practice, a video picture can be taken of the license plate, possibly in combination with an image of the vehicle itself in black/white or colour, or a time/location identifier that is displayed inside or outside of the video camera. Finally, the system is given free for detecting a next signal in block 24.
  • the system may have various extensions or simplifications, such as:
  • the system measures at least one deviation between the vehicle size and the bounding box size: this may pertain to the transition between a motor vehicle and its trailer, or a non- uniform height along the vehicle length, which identifies a passenger car versus a mini-bus.
  • FIGS. 2a, 2b show a three-gantry set-up as seen along the road, and as seen from above, respectively.
  • the far end or down-stream gantry 68 carries the camera arrangement for the front license plate of the vehicle through camera field 72.
  • Near end or upstream gantry 64 carries the camera arrangement for the rear license plate of the vehicle through camera field 70.
  • Middle gantry 66 carries antenna 78 that defines the communication area for the dialog with the vehicle through beam 74, and IR-detectors 76 for detecting the vehicle width in a passive manner.
  • Figure 2b shows a top view of the same arrangement, with vehicle 62, and gantries 64, 66, and 68 clearly shown.
  • the camera fields of view 70, 72 have been shown to extend in a lateral direction. In fact, these fields of view are relatively flat.
  • three contiguous lanes have been shown.
  • the lateral granularity of the IR-detectors is a fraction of the lane width, for example 0.35 m.
  • the lateral granularity of the two rows of cameras is about one lane.
  • the antenna beam 74 has also been shown in this projection, its footprint is an array of stripes each having the width of one lane, and a length that is somewhat larger than its width.
  • Figure 3 depicts a change-of-lane configuration, with respect to cross-lane moving of vehicle 62.
  • the Figure shows two parallel antenna beams 78, each pertaining to a contiguous lane, and the projection of infrared detector array 76.
  • the further black and white dots in the antenna beam area indicate the center of gravity of vehicle 62 at successive instants in time, the black ones indicating instants at which the transaction, including the verification of the vehicle identity, takes place, and the white ones subsequent instants of tracking of the vehicle.
  • the five white dots in the detector array indicate the signal difference between the covered and the non-covered detector elements, respectively, that allow measuring the vehicle width at an accuracy level comparable to the granularity of the detector row.
  • Figure 4 shows size detection of a vehicle.
  • each line shows the parallel signals of the row of IR detectors, a 1 indicating a "vehicle” signal level, and a 0 a "vehicle absent” signal.
  • Successive rows correspond to successive instants depicted in Figure 3.
  • the measurement indicates the detection of five different vehicles. Three thereof show as rectangles, indicating that they keep their lane: a relatively narrow vehicle, 4x6 dots, a wider vehicle, 5x6 dots, and a smaller vehicle, 2x4 dots, that classifies as a motorcycle.
  • the antenna reception indicates the lateral location/position of the vehicle.
  • the matching must be effected with respect to the most recently known lateral position and the vehicle detection with optical measures.
  • Figure 5 shows various beam configurations, in particular for governing the transaction window size for various vehicle categories. Given are the height of the antenna array at 6 metres, and the 5 metres long footprint of the antenna beam. As shown, for a low passenger car the communication area with respect to the on-board-unit is two metres long, which at a speed of 160 km/hr gives a time frame of 90 millisecs to handle the transaction. Likewise, for a high truck having the on-board-unit at 3.6 metres high, and a speed of 80 kms/hr, the time frame is 90 milliseconds as well. As shown in the lower part of the Figure, the antenna sub-beams are 0.7 metres wide. The upper part of the figure shows the quasi footprints of these beams at heights of 1.2 and 3.6 metres, respectively. At intermediate heights, similar data apply as recited above.
  • Figures 6a, 6b show a two-gantry arrangement, that for the remainder is rather similar to the set-up of Figures 2a, 2b.
  • various reference numerals such as beams 70, 72, for effecting the registration, in particular the viewing of the license plates, have been re-used. These beams have an axis making an angle with the horizontal axis of somewhat less than 45°.
  • the communication beam 84 has been attached to the first gantry, and in consequence, looks back to the vehicle. Looking forward would be a feasible solution as well.
  • Figures 6a, 6b As shown, two footprints of the respective vehicle detection beams have a substantial corner part thereof in common. This commonality allows to match the vehicle positions even if, on the relatively short distance separating the two gantries, the vehicle had moved so much as a whole lane's width. Furthermore, if the distance between the two beams is known, the vehicle speed can be measured. In practice, the two gantries are some 6 metres high, so that their distance is in the order of 20 metres. Further, at left in Figure 6a an interval is shown, wherein the front of the vehicle is detected, whereas at the right an interval is shown wherein the rear of the vehicle is detected. In the middle region, the necessary tracking takes place Figure 6b again is a top view. The sequential organization may be viewed as follows:
  • Figures 8a, 8b show a one-gantry arrangement.
  • the rationale for lowering the number of gantries is cost, flexibility, and less required space for building structures.
  • a one-gantry set-up does need no calibrating regarding the distance between the gantries.
  • the usage of three gantries would be a disadvantage with respect to using only two such gantries.
  • these advantages are offset by the higher cost of processing viz a viz the tracking procedure.
  • the viewing beams 70, 72 have been indicated again.
  • the tracking distance is now substantially twice as long as in the two-gantry solution, in as much as the two cameras view forwards and rearwards from the same longitudinal position.
  • Beam 92 is the first detecting beam as discussed with reference to Figure 5.
  • the second detecting beam has not been shown in figures 8a, 8b, cf. Figure 9.
  • the angles of incidence of the various beams can have different values from those shown in the Figures.
  • the registration beams can be directed at regions further away from the gantry structure.
  • further aspects of the vehicle such as colour or size aspects can be taken into account.
  • the tracking of a red or high vehicle might be relatively easy.
  • the set up shown then can be advantageously used to detect various behaviourial aspects of the vehicle, such as for measuring lateral motion, and detecting speed variation patterns in an impending traffic jam situation. It would not be necessary to measure all vehicles, but say, 5 % thereof would be quite sufficient.
  • the fact that the vehicles by themselves may not be a representative selection of the population would not be detrimental, if only their behaviour approaches average behaviour.
  • Figure 9 shows a change-of-lane in the configuration of Figures 8a, 8b, now with detection beams shown on both sides of the gantry structure.
  • the three intervals highlighted at the bottom are the same as those of Figure 7, but have a lengthwise scale that is larger by about a factor of two. This necessitates a larger amount of tracking, causing the time difference between the first and the second vehicle detection to be larger.
  • the two beam footprints have a corner in common. It may be necessary to have these beams somewhat wider in this organization, or rather, to raise their number above the number of lanes.
  • the angle of incidence of the detection beams may be chosen again at lower values.
