  • the present invention relates to a method and a device in accordance with the introduction to the main claim.
  • An object of the present invention is therefore to provide a method and a device which enables the stated drawbacks to be overcome.
  • a particular object is to notify the user-traveller of news on events which can disturb his travel, this news being selected on the basis of travel indications provided by the user.
  • Figure 1 shows a block diagram of a preferred embodiment of the method according to the invention
  • Figure 2 shows an example of an itinerary between a starting point and an arrival point
  • Figure 3 shows a data structure of the journey
  • Figure 4 shows one and the same event with which areas of influence of different shape, one circular and one irregular, are associated;
  • Figure 5 shows the interference or overlap of the itinerary represented in
  • Figure 6 shows an embodiment of the device according to the invention.
  • the method according to the invention provides for the user to supply to the central unit all the information necessary to compare the programmed journey with a series of events, stored in a data bank and continuously updated, which can interfere with the journey by disturbing it.
  • the central unit sends to the traveller in useful time a message on the remote reception device chosen by him.
  • the method of the invention comprises the following steps, each containing a plurality of different stages operating in cascade.
  • communicating the travel data to the central unit by the user comprising a) the means or all means of transport which will be used on the journey, b) the travel itinerary, c) time location data of the journey, such as the journey commencement time and its duration, d) data defining the central reception unit:
  • step 1 commences with the stage 1a) i.e. the selection of the means or all means of transport, for example a ferry, a train for long distances, a local train, an aeroplane, urban public transport, automobile.
  • the choice of the means or all means of transport is preliminary to the insertion of other journey information, as it serves to establish what parameters will be used to define the other attributes of the journey.
  • the choice is made between a plurality of means tabulated and stored in a suitable memory of the "system" of the central unit, the "system” comprising a microprocessor control unit connected to a memory unit, units receiving data and units for transmitting such data.
  • This system will be described hereinafter. It is however also possible that the means of transport are suggested by the system once the best itinerary has been defined, for example using known itinerary planning systems.
  • Stage b) of step 1 comprises, as stated, the choice of itinerary.
  • the travel itinerary can be decided by the user for example with the aid of a known GIS system (Geographic Information System), which, by virtue of a series of very detailed maps present in the memory, and having inserted the starting point and the arrival point, enables the best itinerary between the two points to be defined ( Figure 2).
  • GIS system Geographic Information System
  • stage c the time information of the journey is inserted.
  • the journey time location information (i.e. the beginning and the end) is established on the basis of the type of means chosen.
  • the system comprises a data bank with timetables of trains, aeroplanes, ferries and public transport means, so that, if wishing to use one or other means, the user can choose the time of starting (and consequently of arrival) on the basis of those available. If however the user uses a private means, such as the automobile, the GIS can calculate an estimated time (duration) for the route and it is then possible, having established the starting time and the itinerary, to determine the estimated arrival time.
  • a private means such as the automobile
  • the system calculates on the basis of the transmitted data the so-called data structure of the journey, comprising at least one starting node NP and an arrival node NA and, possibly, different intermediate nodes (N1 , N2, N3 in the figure), connected in succession by segments.
  • the journey times are shown vertically (TP, TN1 , TN2, TN3, TA).
  • an itinerary node is a point in which the traveller can choose to change route (for example change road) or means of transport.
  • change route for example change road
  • means of transport for each means of transport used a schematization such as that illustrated will be made. For example, a traveller can reach NP by plane and then use an automobile.
  • the finishing stage is that in which the user supplies the data relative to his own information reception device, so that the necessary information can be passed to him in a form accessible to him.
  • the reception system is for example a cellular telephone
  • the information which the user must supply is the telephone number and the telephone type (only SMS or graphic information).
  • step 1 If all the data relative to step 1) have been communicated to the central unit (for example via internet or via gprs), the next step can follow, otherwise it returns to the data insertion of step 1 ). It should be noted that the journey time parameters are also required to enable news which can disturb the travel to be notified in good time.
  • step 2 having received the data from the user the system calculates (stage 2a) the checking time range (T1 ; T2) for the events such that its starting moment Ti anticipates the effective start of the journey (or of a part of the journey), to be able to advise the user, even before journey commencement, of events which can in some manner interfere with it.
  • T1 the checking time range
  • the final moment T 2 of this time range is instead positioned after the end of the journey, so that account can be taken of any travel delays.
  • TA TP + C
  • TP is the starting moment and C is the estimated journey duration.
  • the checking time range D [T1 ; T2] during which a check is made on the occurrence of events which can interfere with the journey is:
  • T 1 TP - k and the final moment T 2 of the time range D is:
  • stage 2b of step 2) the time frequency (control programme) with which the stages of step 3) are to be carried out is set. In the example this is 5 minutes. With reference to the notification time range, cited under step 2) stage 2c, this is determined such as to notify in good time any news regarding events which can interfere with the journey (for example every 10 minutes), however notification can also take place in real time. These notifications must in any event reach the user in useful time to make choices such as a change of means of transport or an itinerary modification.
  • the means of transport is a plane, the user must be informed long before the start of the journey, to have the possibility of choosing another flight.
  • Step 3) of the aforedescribed method regards the checking of possible space/time overlaps between the journey and events defined in an events calendar.
  • An event is any situation which can generate interference with a journey; for example an event can be a football match.
  • Said step 3) hence presupposes the existence of an events calendar, which can be drawn up by acquiring data relative to events, to their geographical location and to the moment (time) in which they occur.
  • This calendar is stored in at least one of the memories of the central unit "system".
  • the events calendar is continuously updated and contains a plurality of known events relative to various geographical locations within a very wide time horizon. It also contains information relative to past events, in particular if they can still influence the present.

  • the duration of the influence of an event can consist of time periods which are not adjoining.
  • the traffic within the zone surrounding the stadium will not be influenced, but will be influenced only before the start of the game and after the end (i.e. when the spectators are going to and going from the stadium).
  • the events can be classified on the basis of type (cultural, sporting, commercial) and on the basis of the fact of being able to be predicted with sufficient anticipation (manifestations or fairs) or random (for example accidents or sudden strikes).
  • Step 3) is divided into two stages: in the first stage 3a any spatial overlap between the events and the travel itinerary inserted in step 1 ) is sought; in the second stage 3b any time overlap between the events and the travel itinerary is sought.
  • Clearly spatial overlap or interference regards the itinerary and the event including its area of influence.
  • stage 3a is firstly executed, in order to select from the events calendar only those events which can spatially interfere with the journey itinerary.
  • Figure 5 shows for example the interference or overlap between the itinerary represented in Figure 2 and an event represented in Figure 4 with which a determined area of influence has been associated.
  • the area Zi overlaps the itinerary, and in particular the itinerary portion lying between the nodes N2 and N3.
  • This first operation enables the events to be taken into consideration for the time check to be considerably reduced.
  • the event Ei which interferes with the itinerary, is taken into consideration
  • stage 3b it is also simpler in nature than stage 3b in which time interference with the journey is checked.
  • the traveller arrives at the node N2 indicatively at the moment TN2, but he could arrive at N2 with an anticipation K 2 or a delay Z 1 .
  • the calculation of the delays and anticipations is executed in a like manner to that described for the itinerary NP-NA, considering the stretches NP-N1 as independent sub-itineraries and hence able to suffer their own delays and anticipations.
  • the traveller instead arrives at the node N3 either with an anticipation of
  • the check on time interference is preferably made following the check on spatial interference, in order to reduce the number of events on which to make it. If for one and the same event both the spatial check and the time check are positive, this means that the journey can be influenced by this event and therefore probably disturbed by it. A possible interference must therefore be notified to the traveller.
  • step 4 If a spatial/time interference is verified step 4) is executed, which comprises the stage 4a) in which a message is generated (in known manner for an expert of the art) to be received by the user's reception device, then stage 4b) in which the message is sent. Whether an interference is verified or not, stages 3a) and 3b) are repeated, at the frequency established in stage
  • the message can be a simple written message or include graphic or other information.
  • the message is generated such as to comprise the following information:
  • the means of transport is equipped with a GPS system, which transmits in real time the position of the means to the central unit.
  • the central unit determines a verification area substantially comprising the possible points reachable by the vehicle in a determined time period, by traversing any itinerary within the area.
  • this checking area can be a circle of radius 2 km and centred on the last position of the means of transport determined by the GPS system. Assuming that the means of transport is an automobile, it will traverse 2 km along a town road in indicatively a time period of 4 minutes.
  • this checking area For the definition of this checking area, the direction in which the automobile moves, or other parameters determined by the GPS system, or the average speed travelled by an automobile in town, on a motorway etc. can be taken into consideration.
  • the time period is also susceptible to adjustments due for example to the traffic conditions, etc.
  • the central unit verifies if within the time period (the next 4 minutes) an event will take place within the checking area (2 km) which can disturb the traffic.
  • the central unit executes point 3, verifying whether there is at least one intersection between the area of influence of the event and the aforesaid checking area (the checking area is used instead of the itinerary).
  • time interference is checked as previously. In practice it is checked whether the event, considering starting and finishing times of its consequences, at least partly overlaps the aforedescribed time period (moment in which the GPS coordinates are determined + 4 minutes).
