For example, it may be a parking lot at a rest facility such as a roadside station, a parking lot at another facility, a monthly or hourly parking lot, a vehicle storage area, or a privately owned vacant lot.

[0039] The input unit 520 has a function of receiving various information transmitted from the outside and storing the information in a predetermined storage area of ​​the memory 540 under the control of the central control processing unit 510.

[0043] The ETC information management processing support unit 550 has the function of referencing the distribution and provision destination information storage area 540h under the management of the central control processing unit 510 and distributing and providing the various generated information and judgment information to the outside.

[0044] For example, the ETC information management processing support unit 550 is functionally configured to transmit and provide the generated road traffic survey information, road traffic detection information, parking lot survey information and / or parking lot operation information to a pre-registered external terminal (e.g., output device 600) via the output unit 530 in accordance with set conditions.

[0045] The traffic analysis information generation processing support unit 560 has a function to refer to the traffic congestion information storage area 540e under the management of the central control processing unit 510 and generate automobile traffic congestion information regarding designated or desired roads 14, parking lots 16, automobile passable facilities 17, or automobile parking facilities 18, etc., in real time or continuously for a predetermined period in chronological order.

[0046] The traffic analysis information determination processing support unit 570 has a function to refer to the traffic analysis information storage area 540f under the management of the central control processing unit 510 and generate desired traffic analysis information regarding designated or desired roads 14, parking lots 16, automobile passable facilities 17, automobile parking facilities 18, etc. in real time or continuously for a predetermined period in chronological order. The traffic analysis information determination processing support unit 570 also has a function to generate traffic analysis information regarding road traffic survey information, road traffic detection information, parking lot survey information, or parking lot operation information by day of the week, time period, weather, or automobile-specific information, for the traffic analysis information, in real time or continuously for a predetermined period in chronological order.

[0047] In addition, under the management of the central control processing unit 510, the traffic analysis information judgment processing support unit 570 has the function of detecting and judging abnormal situations, such as detection of vehicles being stuck due to frozen roads or being parked for long periods of time, and judging whether or not a road or the like is passable due to the abnormal situation, in real time or chronologically, continuously for a predetermined period of time, by referring to the abnormality detection information storage area 540g and the road traffic detection program information storage area 540j.

[0048] Furthermore, under the management of the central control processing unit 510, the traffic analysis information judgment processing support unit 570 has a function of referring to the road traffic survey program information storage area 540i and generating traffic analysis program information regarding, for example, cross-sectional automobile traffic volume, average section travel time, average section travel speed, area inflow and outflow volume, number of vehicles traveling within an area, average stay time within an area, and inter-area traffic volume in real time or chronologically continuously for a predetermined period of time.

[0051] Therefore, in the passage authentication information processing system 10, the generated traffic analysis information and abnormality detection information, etc. are not only displayed or output as audio from the output unit 530, but are also functionally configured to be sent via the output unit 530 and distributed or provided to a network-connected terminal device or the like having an output function (e.g., output device 600) in real time or at a preset timing, and to be notified by display output or audio output, etc.

[0052] The operation of the above configuration will now be described.

[0053] First, the overall flow of the service provision process by the passage authentication information processing system 10 using information related to ETC technology will be described.

[0054] When an automobile 12 equipped with an ETC on-board unit 200 passes through an ETC antenna device 300 installed at a predetermined location such as a road 14, a parking lot 16, or a facility 17 through which automobiles can pass or a facility 18 through which automobiles can park and stop, the ETC antenna device 300 detects the passage of the automobile 12 and receives a signal (including automobile identification information and personal identification information) transmitted from the ETC on-board unit 200 (see step S502 in Figure 5).

[0055] This detected and received information is sent to the server 500 via the ETC communication network 400 (step S504).

[0056] The server 500 then refers to the transmitted information and performs a predetermined traffic analysis process (step S506).

[0057] The results of the traffic analysis processing by the server 500 are displayed or output as audio in real time from the output unit 530. The results of the traffic analysis processing are also provided to a terminal device or the like (output device 600) having an output function in real time or at a preset timing, and are notified by display output, audio output, or the like (step S508).

[0058] The traffic analysis process in step S506 will now be described. As shown in Figures 6 and 7, the traffic analysis process can perform predetermined or desired analyses of road traffic surveys, road traffic detection surveys, parking lot surveys, and parking lot operation surveys by day of the week, time period, weather, or vehicle-specific information. In addition, the traffic analysis process can also analyze automobile congestion information (including congestion information) regarding a specified or desired road 14, parking lot 16, or automobile access facility 17 or automobile parking facility 18, as well as analyze the number of automobiles 12 that can be parked by vehicle type (i.e., by vehicle-specific information) in parking lot 16 or automobile parking facility 18, determine and analyze whether or not an entrance / exit gate in parking lot 16 or automobile parking facility 18 can be passed through, and analyze road traffic survey information, road traffic detection information, parking lot survey information, or parking lot operation information by day of the week, time of day, weather, or vehicle type. These processes are performed by the ETC information management processing support unit 550, traffic analysis information generation processing support unit 560, or traffic analysis information judgment processing support unit 570 of the server 500, under the control of the central control processing unit 510, by referring to the corresponding storage area of ​​the memory 540.

[0059] Furthermore, the traffic analysis process determines and analyzes abnormality detection such as automobiles 12 getting stuck due to frozen roads or snow accumulation, or road impassability due to a disaster, and determines whether the analysis results (information) are within a predetermined range, thereby making it possible to output abnormality detection information. This process is also performed by the ETC information management processing support unit 550, traffic analysis information generation processing support unit 560, or traffic analysis information judgment processing support unit 570 of the server 500 under the control of the central control processing unit 510, by referring to the corresponding storage area of ​​the memory 540, as described above. For example, if the automobile 12 remains on the road longer than normal during bad weather, it is determined that there is a risk of the automobile becoming stuck, and abnormality detection information is transmitted. Furthermore, for example, if the automobile 12 is parked in the parking lot 16 for a long period of time, it may be determined to be an abandoned vehicle and abnormality detection information may be transmitted. These processes are also performed by the server 500 with reference to the corresponding storage areas in the memory 540 in the same manner as described above. [Example]

[0060] We will explain the investigation into noise and safety measures that will be implemented to create shortcuts on residential roads. By installing one ETC antenna device 300 at each end of the surveyed section of a one-way road (the entrance side of automobile 12) and the other end (the exit side of automobile 12), and analyzing the traffic volume and vehicle speed according to the frequency of use of the road, it is possible to quantitatively analyze, for example, whether commuter vehicles tend to use the road as a shortcut and exceed the speed limit.

[0061] That is, when the ETC antenna devices 300 installed on one end and the other end detect and receive signals (vehicle identification information and personal identification information) transmitted from the ETC on-board unit 200 installed in the vehicle 12, they send the received information to the server 500. The server 500 references predetermined program information and received information stored in the memory 540 to generate and provide traffic analysis information for the road under investigation by vehicle type, time period, road passing time (passing speed), and vehicle user. This allows for quantitative analysis results to be obtained, such as the fact that the more commuter vehicles use the road as a shortcut and tend to exceed the speed limit.

[0062] In this embodiment, traffic analysis surveys can be conducted unmanned over a long period of time, and quantitative analysis survey results can be provided, which is useful for addressing issues. Moreover, compared to visual inspections or camera images, which are easily affected by weather and installation environment and have poor accuracy, it is possible to obtain more accurate and appropriate data. [Example]

[0063] We will explain how to disseminate information on measures to prevent traffic congestion in tourist areas. By installing a predetermined number of ETC antenna devices 300 on roads 14 leading to tourist destinations and on parking lots 16 at roadside stations and other locations, and analyzing the traffic volume and travel time of automobiles 12 on those roads and parking lots 16 according to their frequency of use, traffic analysis information can be provided in real time, such as the automobile congestion situation on the roads 14 and in the parking lots 16 (including the congestion situation and parking capacity by vehicle type (vehicle-specific information)), the time required to reach the destination, and guidance on detour roads.

[0064] That is, when ETC antenna devices 300 installed at predetermined locations on roads 14 and parking lots 16 detect and receive signals transmitted from ETC on-board units 200 installed in automobiles 12, they transmit the received information to a server 500.
