Description

Technical Field

[0001] The present invention relates to a technology for improving the convenience for parking lot users of a space secured as a parking lot.

Background Art

[0002] The parking lot business of providing a parking space for a vehicle driver to park the vehicle and receiving a consideration for the provision from the driver has existed for a long time. The consideration for the provision (fee) is generally based on the time of occupying the parking space (for example, 10 minutes, 15 minutes).

[0003] The fee may also be adjusted according to the width (exclusive area) of the provided parking space. For example, a "large vehicle space" wider than a "normal vehicle space" is prepared, and the usage fee for the latter is set higher than that for the former.

[0004] In the patent information platform, prior art documents were investigated using the following search formula. Search formula = [Parking lot / TX]*[Classification / CL]*[Subdivision / SP]*[Unit / SP] As a result, 48 hits were obtained, and the following patent documents were verified.

[0005] Patent Document 1 discloses a charging system, a charging method, a program, and a wheel weighbridge that can achieve charging according to the degree of influence on road damage, rather than a fee related to the loading weight in each vehicle.

[0006] Patent Document 2 discloses a technology related to a facility that provides a charging service when the vehicle is an electric vehicle, together with the provision of a parking space. That is, a technique is disclosed that focuses on preventing the charging time from being delayed due to a failure to accurately grasp whether it is executed depending on the power supply state, i.e., a situation where charging is normal, ensuring the charging quality, and specifically applying various conditions considered in electricity charge calculation to enable accurate billing.

[0007] In Patent Document 3, when planning and operating a parking lot in a large-scale multi-purpose facility, it is necessary to consider the purpose of the vehicles using it, such as business, commercial, accommodation, banquet, service vehicles, VIP vehicles, taxis, etc., by day of the week, time zone, vehicle compartment, parking time by purpose, contract type, etc. If there is data on the facility as an example, it should also be considered. A technique that enables dynamic execution of such simulations is disclosed.

Summary of the Invention

Problems to be Solved by the Invention

[0009] Land or space used as a parking lot is generally divided in advance assuming the size of vehicles to define parking sections. On this premise, it is difficult to flexibly respond to vehicles that wish to park.

[0010] For example, a vehicle that requires a larger area than the defined section cannot park because it will interfere with the entry and exit of other vehicles. However, there are sometimes vehicles that park ignoring the defined section.

[0011] Also, even when there is an available section for large vehicles but the section for regular vehicles is occupied, although it is not impossible to park, there are times when this occurs. Since the parking fee for the large vehicle section is set higher than that for the regular vehicle section, an extra parking fee is incurred. However, when the parking fee is free or becomes effectively free due to certain shopping, etc., regular vehicles may park in the large vehicle section.

[0012] In order to solve the above-mentioned problems, repeated studies have been conducted on the flexible and efficient use of the land and space prepared as a parking lot. The problem to be solved by the present invention is to provide a technology for flexibly and efficiently using the land and space prepared as a parking lot.

[0013] In addition, in accordance with the solution means of the present invention, prior patent documents were also searched by the following search formula. [Parking / CL]*[Detection / SP + Detection / SP + Measurement / SP + Measurement / SP]*[Area / CL] As a result, 117 hits were obtained. Therefore, technologies for detecting empty spaces (Japanese Patent Application Laid-Open No. 2018-106479), technologies for detecting lane lines (Japanese Patent Application Laid-Open No. 2018-116579), etc. were verified, but they were not similar to the invention of the present application.

Means for Solving the Problem

[0014] To solve the above-mentioned problems, a first invention related to the structure of a parking lot and a second invention related to a computer program for controlling the parking lot structure according to the first are provided.

[0015] (First Invention) The first invention divides the horizontal direction of the road surface of a parking lot into a large number of sections, and each section is provided with a pressure detection device for detecting the pressure due to the gravity of a vehicle when the vehicle is present on the road surface and / or a light emitting device for emitting light from the road surface. Occupancy area calculation means that receives, as input data, the result of pressure detection in the pressure detection device, and calculates the presence or absence of a vehicle and the occupied area and its area when the vehicle is parked based on the input data. A control device that controls the light emission by the light emitting device for each of the above-mentioned sections based on the occupied area and its area calculated by the occupancy area calculation means. It relates to a parking lot structure provided with (see Fig. 1).

[0016] (Term Explanation) The "section" is a part surrounded by a boundary line when the parkable part on the road surface of the parking lot is divided by a predetermined boundary line. The shape of the section is generally square (see Fig. 1), but other shapes are also acceptable (see Fig. 14).

[0017] One section may be provided with a pressure detection device and a light emitting device, or a section provided with one pressure detection device may be provided with a plurality of light emitting devices (see Figs. 13 and 14). It is desirable to provide a plurality of light emitting devices in one section and to have a plurality of types of colors of the light emitted by the plurality of light emitting devices. This contributes to diversifying the types of information to be transmitted.

[0018] When the section is square, the pitch dimension (denoted as "L" in Fig. 13) for arranging the pressure detection device is preferably smaller (although the manufacturing cost increases) for more accurate calculation of the occupied area and occupancy area. Therefore, although it is more desirable to be smaller (see Fig. 2 in comparison with Fig. 1), due to the relationship with the size of the vehicle, the maximum dimension of the section is approximately at most 500 millimeters. When the maximum value is adopted, the unit for calculating the occupied area of the vehicle is 0.25 square meters per unit. The dimension of the section is currently 10 to 100 millimeters, but if the manufacturing cost can be reduced, even smaller dimensions may be acceptable.

[0019] The section where the light emitting device is arranged is preferably more subdivided than the section where the pressure detection device is arranged. When the section is square, the dimension of one side of the section where the light emitting device is arranged (denoted as "M" in Fig. 13) is set as M = L / 4.

[0020] The "pressure detection device" only needs to be able to detect a pressure (load) equal to or higher than a predetermined value. For example, in addition to a strain sensor that measures a resistance value that changes due to strain caused by a load, there is a load switch that only detects that the deformation of an elastic body has exceeded a predetermined value.

[0021] The "vehicle" includes, in addition to ordinary four-wheel vehicles, large vehicles, special vehicles, motorcycles, light vehicles (bicycles), etc.

[0022] The "occupied area calculation means" includes a predetermined correction means (algorithm for correction calculation and its execution means) corresponding to the pressure detected by the "pressure detection device". As an algorithm for correction calculation, for example, it is shown in FIG. 10. Note that the "area of the occupied area" mainly refers to the area that cannot be used by other vehicles when parking (this meaning in the embodiments described later), but may also refer to the area obtained by projecting the vehicle, and there is room for its definition to vary depending on each parking lot or the management and operation policy of the parking lot.

[0023] (Function) When there is no vehicle in the parking lot, the pressure detection device does not detect pressure in all sections. Suppose a vehicle enters the road surface of the parking lot. The pressure detection device existing in the section where pressure is applied through the wheels of the vehicle detects the pressure due to the vehicle weight. By receiving the input data of the sections where pressure can be detected and those where it cannot, the occupied area calculation means calculates the occupied area and the occupied area of the vehicle. Based on the occupied area and the occupied area calculated by the occupied area calculation means, the control device controls the light emission by the light emitting device for each section. For example, by making the periphery around the place where the vehicle is parked emit light, it is possible to prevent other vehicles from approaching for parking or leaving the warehouse.

[0024] As described above, by the operation of each component, even if the sizes of vehicles vary, the area used by the parked vehicle can be distinguished from other locations. As a result, the land and space prepared as a parking lot can be used flexibly and efficiently.

[0025] (Variation 1 of the First Invention) The first invention may be formed as follows. That is, a protective layer is provided to protect the pressure detection device and the light emitting device from the weight of the vehicle and to transmit the light emitted by the light emitting device to the road surface side (see FIGS. 5, 16, etc.).

[0026] The "protective layer" includes not only the case where it is composed of a single material but also the case where it is composed of a plurality of layers of different materials. A material that can transmit the electromagnetic wave detected by the pressure detection device and can transmit the light emitted from the light emitting device is adopted. For example, tempered glass, thermoplastic resin, etc.

[0027] (Operation) By making the section where the pressure detection device is arranged and the section where the light emitting device is arranged different sections, it may be possible to rationalize the manufacture and operation of the parking lot structure.

[0028] (Variation 2 of the First Invention) The first invention may be formed as follows. That is, the upper surface of the protective layer is formed to have an inclination or / and be curved so as to protrude upward in order not to retain water on the road surface (see FIGS. 15(b) and 16(b)).

[0029] (Term Explanation) It is desirable that the inclination and curvature are such that a person riding in a vehicle using the parking lot structure according to the present invention does not feel discomfort. For example, the angle of the "inclination" is about 1 to 6 degrees. It is desirable that the inclination or / and the curvature that bulges upward be an inclination / curvature in a direction in which a parked vehicle does not move even if it is not using the side brake. A large number of grooves may be provided on the road surface, and only the upper surface of the concave portion of the grooves may be inclined.

[0030] (Function) When the parking lot structure according to the present invention is outdoors, it contributes to preventing rainwater from staying on the road surface due to rainfall. Even when the parking lot according to the present invention is indoors, water may flow on the road surface due to cleaning or other circumstances, but it also contributes to preventing the water from staying in such cases.

[0031] (Variation 3 of the First Invention) The first invention may be formed as follows. That is, a timer that measures the parking time of a parked vehicle based on the pressure detection device, a fee calculation means that calculates a parking fee based on the parking time measured by the timer and the occupancy area calculated by the occupancy area calculation means, a fee output means that outputs the parking fee calculated by the fee calculation means, and is provided (refer to the "cash register" in FIG. 1 etc.).

[0032] (Term Explanation) The "fee output means" includes, in addition to the output screen of the cash register, a data transmission means to the management server when there is a management server that manages the parking lot structure according to the present invention (refer to FIG. 19).

[0033] (Function) Since it is possible to calculate a parking fee according to the occupancy area, it is possible to calculate a reasonable parking fee with a small sense of unfairness.

[0034] (Variation 4 of the First Invention) The first invention may be formed as follows. That is, a parking determination means for determining whether or not it is possible to provide the occupancy area and its area of the vehicle calculated by the occupancy area calculation means for the vehicle attempting to park; When the parking determination means determines that a parking space can be provided, a parking space determination means for determining the parking space to be provided. And the control device is to execute guiding lighting using the light emitting device in order to guide the vehicle attempting to park to the parking space determined by the parking space determination means (see FIG. 9).

[0035] (Operation) The parking determination means determines whether or not it is possible to provide the occupancy area and its area of the vehicle calculated by the occupancy area calculation means for the vehicle attempting to park. When it is determined that a parking space can be provided, the parking space determination means determines the parking space to be provided. The control device executes guidance by turning on or flashing a predetermined light emitting device in order to guide the vehicle attempting to park to the parking space determined by the parking space determination means.

[0036] (Variation 5 of the First Invention) Variation 4 in the first invention may be formed as follows. That is, when the parking determination means determines that a parking space cannot be provided, the control device executes guiding lighting using the light emitting device in order to guide the vehicle attempting to park to leave the parking lot (see S17 in FIG. 12).

[0037] (Operation) When the parking determination means determines that a parking space cannot be provided, the control device executes guidance by turning on or flashing a predetermined light emitting device so as to guide the vehicle attempting to park to leave the parking lot.

[0038] (Second Invention) The second invention relates to a computer program for a control device of a parking lot structure according to the first invention. That is, an electromagnetic wave reception procedure for receiving, as input data, the result of detecting an electromagnetic wave in the pressure detection device in the first invention, an occupancy area calculation procedure for calculating the presence or absence of a vehicle and the occupancy area and its area when the vehicle is parked based on the input data received by the electromagnetic wave reception procedure, a light emission control procedure for controlling the light emission by the light emission device for each of the above-mentioned sections based on the occupancy area and its area calculated by the occupancy area calculation procedure, It is a computer program that causes the above-mentioned control device to execute.

[0039] (Variation 1 of the second invention) The second invention is more preferable as follows. That is, a parking time measurement procedure for measuring the parking time of the parked vehicle based on the above-mentioned pressure detection device, a fee calculation procedure for calculating a parking fee based on the parking time measured by the parking time measurement procedure and the occupancy area calculated by the occupancy area calculation procedure, a fee output procedure for outputting the parking fee calculated by the fee calculation procedure, It is to cause the above-mentioned control device to execute.

[0040] (Variation 2 of the second invention) The second invention is more preferable as follows. That is, a parking determination procedure for determining whether it is possible to provide the occupancy area and its area of the vehicle calculated by the occupancy area calculation procedure for the vehicle attempting to park, a parking space determination procedure for determining a parking space when it is determined by the parking determination procedure that a parking space can be provided, a guidance procedure for executing guidance lighting using the above-mentioned light emission device in order to guide the vehicle attempting to park to the parking space determined by the parking space determination procedure, It is to cause the above-mentioned control device to execute.

[0041] The computer program according to the second invention can also be provided by being stored in a recording medium. Here, the "recording medium" is a medium that can carry a program that cannot occupy space by itself. For example, a flexible disk, a hard disk, a DVD-R, a flash memory, etc. Also, it is possible to transmit from a computer storing the program according to this invention or a control computer of a parking lot structure to a control computer of a parking lot structure through a communication line.

Mode for Carrying Out the Invention

[0044] Hereinafter, embodiments of the present invention will be described with reference to the drawings (FIGS. 1 to 19). The present invention is not limited to the embodiments and is a form for interpreting the present invention.

[0045] (Figure 1) Figure 1 shows a plan view (a) and a cross-sectional view (b) of a parking lot having a square planar shape. The horizontal direction is divided into a number of squares. The dimension of one side of the square was set to 100 to 250 millimeters.

[0046] Each section includes a panel including a pressure sensor that detects pressure due to the vehicle weight from the vehicle when the vehicle is present on the road surface, a panel including a light emitting device that emits light from the road surface (hereinafter simply referred to as "light emitting section"), and a substrate that controls the turning on and off of the light emission in the light emitting section.

[0047] The substrate is connected to a control unit. The control unit receives, as input data, the result of detection of electromagnetic waves in the pressure detection device, and includes an occupancy area calculation means for calculating the presence or absence of a vehicle and the occupancy area and its area when the vehicle is parked based on the input data, and a control device for controlling the light emission by the light emitting device for each of the sections based on the occupancy area and its area calculated by the occupancy area calculation means.

[0048] (Payment machine) The substrate is also connected to a payment machine. The payment machine includes a timer that measures the parking time of the parked vehicle based on the pressure detection device, a fee calculation means for calculating a parking fee based on the parking time measured by the timer and the occupancy area calculated by the occupancy area calculation means, and a fee output means for outputting the parking fee calculated by the fee calculation means (illustration is omitted).

[0049] (Figure 2) Figure 2 shows an embodiment that is more subdivided than the sections shown in Figure 1. If the number of pressure sensors per unit area increases, the estimation of where the vehicle is, its size and weight, etc. will become more accurate. If the number of light emitting sections per unit area increases, a colorful display and a detailed setting of the area occupied by the vehicle (see Figures 4(b) and 6) will be possible.

[0050] (Figure 3) Figure 3 shows the road surface of the aforementioned parking lot structure when the vehicle is moving (a) and when it is moving slowly (b). In Figure 3(a), it is illustrated that while the vehicle is moving, the pressure sensor under the wheel is detecting pressure.

[0051] In Figure 3(b), it is illustrated that the vehicle that has started to move slowly has advanced further than in Figure 3(a), and the location of the pressure sensor under the wheel has also changed.

[0052] (Figure 4) Figure 4 shows the case where the vehicle has stopped on the road surface of the aforementioned parking lot structure (a) and the case where it has come to a stop at the parking position (b).

[0053] Figure 4(a) shows that the position of the pressure sensor that detected pressure due to the vehicle's stop has been identified. The pressure sensor transmits, as an electrical signal to the control unit, which pressure sensors have detected pressure and which have not detected pressure via the substrate. Then, the electrical signals from each pressure sensor are analyzed, and by referring to a database regarding the size of the vehicle, etc. (see Figure 11), the area occupied by the vehicle and its area are calculated. The determination of the area occupied by the vehicle and its area will be described in detail in Figure 11.

[0054] In the light-emitting layer, the control unit causes to emit light the portion corresponding to the outer peripheral part of the area occupied by the parked vehicle In Figure 4(a), the type of hatching of the illuminated section (light-emitting section) is shown changed. For the driver operating the vehicle, the light-emitting section can indicate which area the vehicle should be parked in and which area it occupies and borrows after parking.

[0055] (Figure 5) Figure 5 shows an embodiment provided with a protective layer that serves as the road surface covering the surface that is the upper end of the pressure sensor and the light-emitting section. The protective layer is made of a material that can transmit the electromagnetic waves detected by the pressure detection device and can also transmit the light emitted from the light-emitting device. For example, it may be composed of a single material such as tempered glass or thermoplastic resin, or it may be composed of multiple layers of different materials.

[0056] (Figure 6) Figure 6 shows, in a plan view, a vehicle parked in a parking lot equipped with the parking lot structure according to this embodiment. The area around the area occupied by the vehicle, which is slightly larger than the area occupied by the vehicle, is emitting light. Different from the conventional parking lot where white lines are painted on the road surface to indicate the parking area, the entire parking lot can be used flexibly.

[0057] The area that is slightly larger than the area occupied by the vehicle becomes the area borrowed by the vehicle for parking. For that area, a camera (such as Figure 8) described later takes a photo of the vehicle about to enter the warehouse, and by using the result of analyzing the vehicle photo, a more detailed area setting can be made possible.

[0058] For example, in the case of a right-hand drive vehicle, the area can be set with a slightly wider space on the steering wheel side of the parked vehicle, taking into account the ease of getting in and out. Also, in the case of a vehicle loaded with luggage, the area can be set with a "luggage handling space" provided behind the parked vehicle.

[0059] (Figure 7) Figure 7 shows the state (a) where the driver has left the vehicle after parking and the state (b) where a person has approached the vehicle. In Figure 7(a), when the driver leaves the vehicle and there are no people or vehicles around, the light emission by the light-emitting layer is not necessary, so it shows a state where the light is turned off.

[0060] In Figure 7(b), a human presence sensor (not shown) detects that a person is approaching the parking lot or the parked area, and in order to indicate the area occupied by the parked vehicle, a predetermined section of the light-emitting layer is emitting light, showing the state. Although not shown in the drawings, when another vehicle approaches within the parking lot, the light sensing panel detects this, and similarly, a predetermined section of the light emitting layer emits light.

[0061] (Fig. 8) Fig. 8 shows, in a plan view, that a vehicle about to park has appeared at a parking lot having an L-shape with a parking lot structure according to the present embodiment facing a general road, separate from a vehicle already parked.

[0062] At the entrance of the parking lot from the general road, there is a gate that opens when a vehicle about to enter is detected (there may be no gate in a small-scale parking lot or a parking lot that substitutes with number plate photography, etc.), and a camera that photographs the vehicle type and number plate of the vehicle about to enter from the gate or a sensor capable of detecting the presence of the vehicle.

[0063] (Fig. 9) Fig. 9 shows the case where a vehicle about to park enters the parking lot. For the driver of the vehicle about to park to see, a predetermined section of the light emitting panel is lit for guidance to the place where parking should be done. Also, at the end of the lighting for guidance, a predetermined section of the light emitting panel indicating the area for parking is flashing.

[0064] (Fig. 10) Fig. 10 shows the relationship between the vehicle and the parking lot structure according to the present embodiment immediately before and immediately after the vehicle about to park shown in Figs. 8 and 9 attempts to enter the parking lot from the general road.

[0065] Fig. 10(a) shows, in a plan view, immediately before the vehicle attempts to enter the parking lot from the general road, and Fig. 10(b) shows the state where the vehicle is omitted for the parking lot structure in that state. When the pressure sensor at the boundary between the parking lot and the general road detects pressure, the area occupied by the vehicle and its area are not determined.

[0066] In Fig. 10(c), a plan view shows the vehicle immediately after entering the parking lot, and in Fig. 10(d), the parking lot structure in that state is shown with the vehicle omitted. There is no pressure sensor that has detected pressure at the boundary between the parking lot and the general road because the vehicle has completely entered the parking lot.

[0067] At a certain moment after that, based on the data on where the pressure sensor that has detected pressure is located, the control unit calculates the area and its size that the vehicle occupies when parked. Then, it calculates a place where the calculated area can be provided and outputs a lighting command for guiding the vehicle to that place to a predetermined light-emitting panel.

[0068] (Fig. 11) Fig. 11 shows the algorithm of the procedure for calculating and determining the area occupied by the vehicle. The "occupied area" is not the area surrounded by connecting the parts where the vehicle applies its weight to the pressure sensors, but the area that other vehicles cannot use when parking, and it is an essential value when determining the parking fee.

[0069] The control unit acquires data on the pressure sensors that have detected pressure from the vehicle's wheels at a certain moment via the substrate (S1).

[0070] Subsequently, the vehicle width and wheelbase dimensions are determined (S2). If the pressure sensors are installed finely, the tire width can also be detected, which is useful for identifying the vehicle in that case. Regarding the vehicle width and wheelbase dimensions, a data group is pre-stored in a database. The vehicle type is estimated using that database (S3). The image by the camera shown in Fig. 8 may also be used for identifying the vehicle type (S4).

[0071] Once the vehicle type is identified, it is calculated how large the vertical and horizontal sizes are as the area occupied by that vehicle type (S5). Then, a control signal for instructing light emission is transmitted to the light-emitting part indicating the occupied area (S6). Then, the light-emitting part surrounding the occupied area is made to emit light (S7).

[0072] (Figure 12) Figure 12 is a flowchart in the case where, after a vehicle enters a parking lot, an algorithm for determining a parking location and guiding the vehicle to the parking location is executed.

[0073] First, it is determined what kind of occupancy area the entering vehicle requires (S6). Note that what kind of occupancy area is required was described with reference to FIGS. 10(a) to (d).

[0074] Subsequently, it is determined whether the determined occupancy area can be provided by the parking lot at the current time (S12). If it is determined that it cannot be provided, guidance for exiting will be displayed (S17). And in that case, it is confirmed that the vehicle has exited the parking lot, and the process ends (S18).

[0075] If the determined occupancy area can be provided, the parking location for the vehicle is determined (S13). Then, a guidance display (such as FIGS. 10(c) and (d)) for the vehicle to move to the parking location is executed by controlling the light-emitting layer by the control unit according to the section (S14).

[0076] The control unit can grasp how the pressure sensor changes when the vehicle moves according to the guidance display. If another guidance display is required according to the movement, the guidance display is also moved (S15).

[0077] When the vehicle stops in the area to be parked (shown in FIG. 6) guided by the guidance, the pressure sensor in that area stops detecting pressure, so the control unit can grasp that the vehicle has stopped at the parking location (S16). By detecting that a predetermined time has elapsed since parking, the guidance to the parking location ends (S19).

[0078] (Figure 13) Figure 13 is a plan view (a) and a cross-sectional view (b) showing variations in the arrangement of the pressure sensor and the light-emitting part.

[0079] With respect to the pitch L at which the pressure sensors are arranged, the section M for forming the light-emitting layer is set to one-fourth. As specific dimensions of L, 100 millimeters are used, and for M, 25 millimeters are used. However, it is not necessary for the present invention to have these dimensions or the aforementioned ratio.

[0080] Regarding M, the smaller it is, the more diverse the information provided to the users of the parking lot (not limited to vehicle drivers. For example, pedestrians walking near the parking lot, etc.) can be.

[0081] (Figure 14) Figure 14 is a plan view (a) and a cross-sectional view (b) showing a case where the shape of the section of the panel embedded with the pressure sensors is a regular hexagon instead of a square, and the shape for forming the section of the light-emitting part is an equilateral triangle that divides the aforementioned regular hexagon into six equal parts. As shown in this figure, the shape of the section embedded with the pressure sensors and the shape of the section of the light-emitting part are not limited to squares.

[0082] (Figure 15) Subsequently, a structure for preventing water such as rainwater from flowing on the road surface will be described. This is to prevent rainwater from accumulating when the parking lot is outdoors, and also because water may be used during cleaning even when the parking lot is indoors.

[0083] In Figure 15(a), it is a parking lot structure without a protective layer, and the entire structure composed of a layer in which panels with pressure sensors and panels with light-emitting parts are alternately arranged and a substrate is inclined.

[0084] The inclination angle θa is generally about 0.5 to 6 degrees. However, the appropriate inclination angle varies depending on the location (each parking lot) where the present invention is adopted. The direction of the inclination should generally be the left-right direction, not the front-rear direction of the parked vehicle. This is to prevent the vehicle from moving even if the side brake of the vehicle is accidentally left on.

[0085] Figure 15(b) shows a case where an inclination is formed only by the protective layer that will form the upper surface of the road surface. In this embodiment, the protective layer is formed such that the area below the parked vehicle is a peak and slopes downward in the left-right direction. The inclination angle θb is generally about 0.5 to 6 degrees, but the appropriate value also varies for each parking lot. Compared with Figure 15(a), there is an advantage that it is less likely to give a sense of discomfort to passengers getting into the vehicle such as the driver.

[0086] Figure 16(a) shows an embodiment in which only the protective layer is inclined in one direction. The inclination angle θc is also generally about 0.5 to 6 degrees, but the appropriate value also varies for each parking lot.

[0087] Figure 16(b) shows an embodiment in which only the protective layer is curved to be convex upward. The average inclination angle θd of the curved part is also generally about 0.5 to 6 degrees, but the appropriate value also varies for each parking lot.

[0088] (Figure 17) In the embodiment shown in Figure 17, the light-emitting part is provided with a heat-generating material and is provided as a parking lot structure in an area with snow accumulation. In this figure, not all of the light-emitting parts are provided, but they are provided alternately. The heat-generating material converts the electrical energy provided through the substrate into heat energy and functions to melt the snow on the road surface.

[0089] Although illustration is omitted, in an embodiment including a protective layer, the protective layer may be provided with a heat-generating material. Also, if the light-emitting part generates heat when emitting light, the aforementioned heat-generating material can be omitted.

[0090] Instead of the heat-generating material, a structure may be provided in which water or warm water is jetted onto the road surface to melt the snow. In a place where water at a water temperature capable of melting snow can be obtained, it is also possible to replace the heat-generating material by providing a structure in which such water flows little by little.

[0091] (Figure 18) FIG. 18 conceptually shows that when the parking lot structures according to the present invention are respectively adopted in a plurality of parking lots A, B, and C, a data transmission device is provided for transmitting data received or processed by a control unit to a parking lot management server.

[0092] In the parking lot management server, data transmitted from each of the parking lots A, B, and C is received by a data receiving device and stored in a parking lot management database. Although not shown in the figure, it is also possible to transmit data from the parking lot management server to each of the parking lots A, B, and C. The data to be transmitted includes a computer program executed by the control unit. Therefore, it becomes easy to update the computer program executed by the control unit.

[0093] (FIG. 19) FIG. 19 shows the data transmission device shown in FIG. 18 as a cash register. The control units and the cash registers in each of the parking lots A, B, and C perform bidirectional data transmission and reception, and various data can be transmitted to the parking lot management server via the cash register.

[0094] According to the embodiment shown in FIG. 19, the parking lot management server can receive parking fees and data serving as the basis for calculating the fees. By collecting these data and analyzing the collected data, it contributes to more reasonable operation and management of the parking lot.

[0095] Although not shown in the figure, the fact that it is also possible to transmit data from the parking lot management server to each of the parking lots A, B, and C is the same as the embodiment of FIG. 18. The data to be transmitted includes a computer program executed by the cash register, a computer program executed by the control unit, and the like.

[0096] According to the foregoing embodiments, it is possible to provide a parking lot structure for flexibly and efficiently using the land and space prepared as a parking lot. For example, since it is possible to rationally arrange the area occupied by the vehicle by parking, flexible responses such as increasing the number of vehicles that can be parked and reasonably charging vehicles that occupy beyond the specifications are made possible.
