- Such sensors 6 are well known in the state of the art and commonly used, so that they will not be described in detail here.
- the measurements made by the sensors 6 are grouped together in a central computer station 7, by wire or radio links.
- This central station 7 is connected to one or more fixed base stations 8 for paging, where it can optionally constitute itself a fixed base station for paging, for transmitting predetermined radio messages comprising digital information relating to the elementary journey times of vehicles on each of sections 4 of the road network 1.
- the radio messages in question can be coded for example according to the European standard "ERMES" (EEC Directives 85/374 and 92/59) or according to any other protocol unilateral or possibly radiotelephony radio messaging. These radio messages are transmitted at regular time intervals by the fixed base station 8, for example every three minutes.
- these predetermined radio messages are transmitted among other radio messages carrying either general information or personalized messages intended to be consulted later by their recipients on portable paging receivers.
- the predetermined radio messages in question may include, for example: an identification field enabling portable paging receivers to recognize that these are messages containing digital data relating to travel times on the road network, and a series of digital information representative of elementary journey times updated on different sections 4 of the road network 1, these numerical values being able to consist, for example, either of average traffic speeds on each of the sections 4 considered, or of travel times elementary on said sections 4 (calculated for example in the central station 7 as a function of the speeds measured by the sensors 6 and of the lengths of the sections 4), the identification of the sections 4 corresponding to the circulation speeds or to the elementary journey times updated as well transmitted, this identification can for example be constituted by a nude mero, or by the start and end points of each section, and this identification can possibly be omitted if each radio message includes information relating to all the sections 4 of the road network, always presented in the same order, - and where applicable, accessibility data relating to at least certain sections 4 of the network and / or doors 5, accessibility data which indicates whether a section 4 or
- the radio messages carrying information relating to the travel times are received by the users on portable paging receivers 10 such as that represented in FIG. 2 or, where appropriate, on radio telephones having paging functionalities. .
- Each of these receivers is in the form of a light autonomous box (weighing less than 100 g, for example) which is provided with an alpha-numeric screen 11 and a simplified keyboard 12 comprising for example four keys, namely: a key 13 allowing access to special functions, two scrolling keys 14 making it possible to move a cursor on the screen 11 and / or to select particular zones of said screen, zones which will be said below after "icons", - and a validation key 15 used to validate the selections made on the screen using the keys 14.
- FIG. 3 shows a partial block diagram of the receiver 10, which conventionally includes: - an antenna 16 for receiving radio messages transmitted by the fixed base station 8, a reception device 17 (REC.) Including in particular, on the one hand an amplifier 18 (AMPLIF.) receiving the signals picked up by the antenna 16, and on the other hand, a demodulator 19 (DEMOD.) receiving the signals amplified by the amplifier 18, a central unit 20 (CPU) which receives the demodulated signals at the output of the demodulator 19, this central unit 20 comprising a microcontroller or microprocessor 21 (MP) connected to a clock 22 (CL.) and to at least one memory 23 ( MEM) (the clock and the memory may possibly not be included in the central unit 20), and the microprocessor 21 being connected to the screen 11, to the keyboard 12, as well as to signaling means capable of attracting the attention of a user, for example an electronic bell 24 and / or a vibrator 25.
- MP microcontroller or microprocessor 21
- CL. clock 22
- MEM memory 23
- the microprocessor 21 can advantageously be connected to a card reader 38 adapted to communicate with a portable memory card 37 (FIG. 2).
- the card reader 38 can be used for example to operate the central unit 21 according to a program making it possible to use the radio messages relating to the travel times on the road network 1 (either by loading this program into the unit central 21, or by allowing the central unit 21 to execute this program inside the card 37), as explained in French patent application No. 97 02857 filed on March 11, 1997.
- the card reader 38 can also be used to authorize or not the exploitation of radio messages relating to travel times on the road network 1, according to a validity datum (number of units representative of a certain amount of money paid in advance, or subscription deadline) which is read in card 37, for example as taught in French patent application no. 97 02856 filed on March 11, 1997.
- the radio paging receiver 10 which has just been described operates as follows.
- the microprocessor 21 recognizes in this message an identification number which is specific to the receiver 10, and it stores this message in the memory 23 by actuating simultaneously the buzzer 24 and / or the vibrator 25, so that the user is warned of the arrival of a message which concerns him.
- This user can then consult this message on screen 11, then if necessary erase it from memory 23.
- the microprocessor 21 recognizes this message by the identification field contained in said message or by an address contained in this message is common to all the receivers 10 authorized to use the radio messages relating to travel times on the road network 1.
- the microprocessor operates neither the ring 24 nor the vibrator 25, but on the contrary is content to store the information thus received in a part of the memory 23 dedicated to traffic information.
- This part of the memory 23 contains for example: topology data relating to the road network 1, this topology data comprising for example the identification of the starting points and of the end points of each section 4 of the road network, as well as the length of said sections, accessibility data, indicating whether the sections 4 and the doors 5 are accessible or not to motorists, and digital data relating to the elementary journey times, on the various sections 4 of the road network, this digital information may consist, for example, of an average speed of circulation on each section 4, or directly in an average journey time on each of said sections.
- the digital data relating to travel times and the accessibility data are thus updated regularly in the memory 23.
- the topology data of the road network 1 can also be updated from time to time, when sections 4 of the road network are newly created, or when such sections 4 are newly integrated into the road information system.
- This updating of the topology data can be carried out by means of radio messages or possibly by reading a memory card 37 if the receiver 10 is provided with a memory card reader 38, or by any other means.
- the user of the receiver 10 wants to obtain information on a journey time in the road network 1, he begins by selecting and confirming a corresponding option in the general menu which is displayed on the screen 11 when the receiver 10, which shows on the screen 11 the display presented in FIG. 4.
- This display includes four screen areas or "icons”, which can be selected using the keys 14, namely: an icon 26 representing a schematic plan of the internal peripheral 2, the various sections 4 of this internal peripheral being represented by lines whose visual characteristics correspond to the average speeds of circulation which are stored in the memory 23 or which are calculated by the microprocessor 21 on the basis of the elementary journey times and of the lengths of sections stored in said memory 23 (the zones where the circulation is fluid, that is to say where the average speed of circulation is for example greater than 60 km / h , are shown in dotted lines; the slowdown zones, that is to say where the average speed of circulation is for example between 40 and 60 km / h, are shown in solid lines; and the traffic jam zones, c ' that is to say where the average speed of circulation is for example less than 40 km / h, are represented in thick lines), a second icon 27 which represents a schematic plan of the external device 3, with the same symbolization as for the icon 26, an icon 28 comprising the text "bis", and an icon 29 comprising the text "mem”.
- the central unit 20 then presents on the screen 11 a display such as that of FIG. 5 initially without the text zones indicating "A" and "Mute” in said FIG. 5.
- a first text zone containing the word "DE” to announce the starting point of the journey desired by the user of the housing 10
- a second text area 31 where a name or possibly a number appears identifying one of the doors 5 of the external device 3 (in this case "Clichy").
- the user can scroll successively through different names of doors 5 in the text zone 31, using the keys 14, until the appearance of door 5 corresponding to his desired starting point.
- a square 32 which schematically indicates the position of the door 5 corresponding to the starting point, on the external device 3.
- the user validates the choice of his starting point by means of the validation key 15, after which appears on the screen a new text zone 33 which also displays the name of a door 5 in the occurrence "Mute", below another text zone comprising the word "to" to indicate that the second door name corresponds to the end point desired by the user of the housing 10.
- the user then selects door 5 corresponding to the desired end point using the keys 14, which shows on the schematic plane 30 a second square 34 corresponding to the approximate position of said point of arrival, then this user validates his choice by means of the key 15.
- the microprocessor 21 then shows on the screen 11 the display represented in FIG. 6, which indicates the doors 5 corresponding respectively to the desired point of departure and to the point of arrival, and the estimated journey time between these points of departure and of arrival, in this case 9 min .
- This estimated journey time is calculated by the microprocessor 21 as being the sum of the elementary journey times on the different sections 4 constituting the journey between the desired departure and arrival points. These elementary journey times are either directly stored in the memory 23 and updated directly by the radio messages received, or calculated by the central unit 21: from average circulation speeds stored in the memory 23 for each section 4 and updated by radio messages received, and from the lengths of sections stored in said memory 23.
- the display shown in FIG. 6 can advantageously also show the schematic plane 30 of the external device 3, with the squares 32 and 34 positioning the starting and ending points.
- the display presented in FIG. 6 also preferably includes a visual representation of the distance to be traveled between the departure and arrival points.
- This visual representation is in this case constituted by a strip 35 lying between two horizontal lines, this strip 35 being marked out by symbols 36 representing the different gates 5 between the starting point and the end point, and said strip 35 having a different aspect depending on the fluidity of the sections 4 of the road network located between the doors corresponding to the symbols 36.
- the sections where the average traffic speed is greater than 60 km / h are shown in white, the sections where the traffic speed is between 40 and 60 km / h are shown in dotted lines, and the sections where the traffic speed is less than 40 km / h are blackened.
- the display presented in FIG. 6 may possibly also include information relating to the accessibility of the sections 4 and of the doors 5 comprised between the desired starting point and the finishing point. For example, sections 4 or doors 5 closed to the public can be marked with an "X" symbol.
- microprocessor 21 displays on the screen
- a warning message such as "blocked traffic” instead of the estimated journey time.
- the display presented in FIG. 6 may possibly also display a message such as "?” or "invalid data” when the digital data those used to calculate the journey time are too old.
- the memory 23 can include, for each section 4 of the road network, the date and time at which the elementary journey time and / or the average traffic speed on this section was updated for the last time.
- the microprocessor 21 checks that the updates of the different sections 4 comprised between this starting point and this ending point do not are not too old.
- the microprocessor 21 will display the aforementioned warning message "invalid data” or "?” if the data relating to one of the sections 4 included between the departure point and the desired arrival point has not been updated for more than half an hour.
- the memory 23 could only include an update date and time for all of the sections 4, if the digital data relating to all the sections 4 are updated at the same time with each radio message received.
- microprocessor 21 is advantageously designed to cyclically update the last estimated travel time TO consulted by the user, for example for a period of 15 minutes after the end of the last consultation carried out by the user.
- the microprocessor 21 compares the initially estimated travel time TO corresponding to the last consultation of the user, with the same updated travel time T, and said microprocessor operates the buzzer 24 and / or the buzzer 25 when the difference ⁇ T between these two times becomes greater than a predetermined value, which predetermined value can be an absolute value (for example 5 min) or a relative value (for example 20% of TO) .
- the operation of the device 10 is similar to that described previously if the user selects and validates the icon 26 corresponding to the internal device 2.
- the microprocessor 21 immediately displays a presentation such as that of FIG. 6, giving the updated travel time corresponding to the last consultation carried out by the user.
- the initial storage of a particular route can be carried out for example when the screen has the display shown in FIG. 6, then pressing the key 13 of special functions, which brings up a storage menu.
- the central unit 21 instead of obliging the user to initially choose between the icons 26 and 27 corresponding respectively to the interior and exterior peripherals 2,3, it might be possible to provide that the central unit 21 calculates the respective journey times between the desired departure and arrival points, on the one hand, by the internal peripheral 2, and on the other hand, by the external peripheral 3, the two estimated journey times being thus presented to the user on screen 11.
- the microprocessor 21 could thus calculate the two journey times corresponding to the two possible routes between the desired departure and arrival points, respectively by the internal peripheral 2 and by the external peripheral 3, but said unit central would only display the minimum travel time indicating whether this minimum travel time corresponds to the interior device 2 or to the exterior device 3.
