Description

L'invention se rapporte à un procédé de régulation du trafic d'un système de transport comportant des véhicules circulant sur une voie munie de plusieurs stations d'arrêt.The invention relates to a traffic control method of a transport system comprising vehicles traveling on a track provided with several stopping stations.

Il est connu dans les systèmes de transport de réguler le trafic par asservissement d'horaire. Il est notamment connu, pour les métros, de contrôler la marche des véhicules de sorte que l'intervalle de temps entre deux véhicules soit sensiblement constant. Un tel procédé de régulation présente l'avantage de limiter le temps d'attente des voyageurs dans les stations d'arrêt et de contribuer à une bonne répartition de la charge des voyageurs dans les différents véhicules lorsque le flux de voyageurs parvenant dans les stations d'arrêt est régulier. Toutefois, dans la pratique le flux de voyageurs parvenant dans une station de métro est irrégulier, notamment lorsque la station permet une correspondance avec d'autres lignes de métro. Ainsi, l'arrivée ponctuelle d'un flux important de voyageurs engendre le plus souvent une surcharge du premier métro parvenant dans la station et une sous charge du métro suivant, la majorité des voyageurs attendant sur le quai préférant rentrer dans le premier métro. Un procédé d'information sur l'horaire estimé d'arrivée du prochain véhicule d'un système de transport indiquant notamment la charge en passagers de ce véhicule est décrit dans le document WO 98/08206 A . Cette information permet aux voyageurs attendant sur le quai de choisir une autre route ou d'attendre qu'un autre véhicule moins chargé soit annoncé.It is known in the transport systems to regulate traffic by clock servo. It is particularly known, for metros, to control the operation of vehicles so that the time interval between two vehicles is substantially constant. Such a regulation method has the advantage of limiting the waiting time of travelers in the stopping stations and of contributing to a good distribution of the load of travelers in the different vehicles when the flow of passengers arriving at the stations of stop is regular. However, in practice the flow of passengers arriving at a metro station is irregular, especially when the station allows a connection with other subway lines. Thus, the punctual arrival of a large flow of travelers usually generates an overload of the first metro arriving in the station and an under load of the next metro, the majority of travelers waiting on the platform preferring to enter the first metro. A method of information on the estimated time of arrival of the next vehicle of a transport system including the passenger load of the vehicle is described in document WO 98/08206 A . This information allows travelers waiting on the platform to choose another route or wait for another less loaded vehicle to be announced.

Le but de la présente invention est donc de remédier à ces inconvénients en proposant un procédé de régulation du trafic d'un système de transport qui permette d'obtenir une meilleure répartition du nombre de passagers entre les différents véhicules du système de transport et qui soit simple et économique à mettre en oeuvre.
L'invention a pour objet un procédé de régulation du trafic d'un système de transport selon la revendication 1.The purpose of the present invention is therefore to overcome these drawbacks by proposing a method for regulating the traffic of a transport system which makes it possible to obtain a better distribution of the number of passengers between the different vehicles of the transport system and which is simple and economical to implement.
The subject of the invention is a method for regulating the traffic of a transport system according to claim 1.

  • the figure 1 is schematic view of a line of a transport system equipped with a central control unit implementing the control method according to the invention;

Pour faciliter la lecture du dessin, seuls les éléments nécessaires à la compréhension de l'invention ont été représentés. Les mêmes éléments portent les mêmes références d'une figure à l'autre.To facilitate the reading of the drawing, only the elements necessary for the understanding of the invention have been represented. The same elements bear the same references from one figure to another.

La figure 1 représente un système de transport, du type métro ou tramway, comportant une ligne de voie ferrée comprenant au moins trois stations d'arrêt S1, S2 et S3 munie chacune d'un quai d'embarquement. Sur cette ligne circulent notamment trois véhicules A, B et C qui sont commandés dans leurs déplacements par une unité de régulation centrale.The figure 1 represents a transport system, of the metro or tramway type, comprising a railway line comprising at least three stopping stations S1, S2 and S3 each provided with a loading dock. On this line circulate including three vehicles A, B and C which are controlled in their movements by a central control unit.

L'unité de régulation centrale comporte un fonctionnement nominal dans lequel la régulation du trafic est effectuée suivant un asservissement horaire, chaque véhicule quittant une station à un horaire donné et étant séparé d'un autre véhicule d'un écart de temps constant. Ce fonctionnement nominal est conservé tant que la charge en passagers dans chacun des véhicules ne dépasse pas un seuil de surcharge affecté au véhicule, cette charge étant déterminée en mesurant la masse de passagers présents dans le véhicule, par exemple au moyen de capteurs disposé sur chacun des bogies du véhicule. Le seuil de surcharge pour chacun des véhicules peut être déterminé expérimentalement et correspond par exemple à la masse de passagers pour laquelle la proximité des personnes entre elles est telle que le voyage devient inconfortable.The central control unit has a nominal operation in which the traffic control is performed according to a time control, each vehicle leaving a station at a given time and being separated from another vehicle by a constant time difference. This nominal operation is retained as long as the passenger load in each of the vehicles does not exceed an overload threshold assigned to the vehicle, this load being determined by measuring the mass of passengers present in the vehicle, for example by means of sensors disposed on each of the bogies of the vehicle. The overload threshold for each of the vehicles can be determined experimentally and corresponds, for example, to the mass of passengers for whom the proximity of the persons to each other is such that the journey becomes uncomfortable.

Conformément à l'invention, lorsque l'unité de régulation centrale est alertée d'un état de surcharge sur un véhicule, par exemple par la réception d'un signal émis par le véhicule en situation de surcharge, l'unité de régulation centrale modifie la vitesse et/ou les temps d'arrêt de certains véhicules par rapport au fonctionnement nominal afin de réduire le nombre de passagers susceptibles de monter dans le véhicule surchargé. Le signal de surcharge émis par les véhicules peut par exemple être communiqué à l'unité de régulation centrale par des moyens de communication équipant habituellement les véhicules, tel que par ondes radioélectriques libres ou guidées au travers d'un guide d'ondes disposé en bordure de la voie ferrée.According to the invention, when the central control unit is alerted to an overload condition on a vehicle, for example by receiving a signal transmitted by the vehicle in an overload situation, the central control unit modifies the speed and / or downtime of certain vehicles in relation to the nominal operation in order to reduce the number of passengers likely to get into the overloaded vehicle. The overload signal emitted by the vehicles may, for example, be communicated to the central control unit by means of communication usually fitted to the vehicles, such as by free radio waves or guided through an edge waveguide. of the railway.

La figure 2 illustre, à titre d'exemple, un premier mode de réalisation du procédé de régulation selon l'invention dans lequel les véhicules qui sont surchargés sont accélérés temporairement jusqu'à la prochaine station, afin de quitter cette station en avance sur l'horaire initialement prévu, puis sont ensuite ralentis dans le trajet menant à la station suivante de manière à quitter cette station à l'horaire initialement prévu.The figure 2 illustrates, by way of example, a first embodiment of the regulation method according to the invention in which the vehicles which are overloaded are accelerated temporarily until the next station, in order to leave this station in advance of the schedule initially expected, then are slowed down in the path to the next station to leave the station at the scheduled time.

Dans cet exemple on considère que le temps d'arrêt des véhicules dans chaque station est invariable, par exemple de l'ordre de 20 secondes, et qu'en condition nominale de fonctionnement, c'est à dire lorsque aucun des véhicules A, B et C n'est en état de surcharge :

  • le véhicule A quitte la station S1 à to, la station S2 à t0+100s et la station S3 à t0+200s ;
  • le véhicule B quitte la station S 1 à t0+100s, la station S2 à t0+200s et station S3 à t0+300s ;
  • le véhicule C quitte la station S 1 à t0+200s, la station S2 à t0+300s et station S3 à t0+400s.
In this example, it is considered that the stopping time of the vehicles in each station is invariable, for example of the order of 20 seconds, and that in nominal operating condition, that is to say when none of the vehicles A, B and C is not overloaded:
  • vehicle A leaves station S1 at to, station S2 at t 0 + 100s and station S3 at t 0 + 200s;
  • vehicle B leaves station S 1 at t 0 + 100s, station S2 at t 0 + 200s and station S3 at t 0 + 300s;
  • vehicle C leaves station S 1 at t 0 + 200s, station S2 at t 0 + 300s and station S3 at t 0 + 400s.

Lorsque le nombre de passagers montant dans le véhicule B au niveau de la station S 1 est tel que véhicule B se trouve dans un état de surcharge, l'unité de régulation centrale reçoit alors automatiquement un signal de surcharge de la part du véhicule B, ce signal de surcharge étant élaboré par le véhicule B à partir de capteurs de charge présent sur ses bogies. A partir de cette information, l'unité de régulation centrale commande le départ du véhicule B surchargé de la station S1 à l'horaire prévu mais ordonne, dans un premier temps, au véhicule B d'accélérer entre les stations S1 et S2 au-delà de l'accélération prévue dans les conditions nominales de fonctionnement de sorte que ce véhicule B arrive 20 secondes en avance à la station S2 et quitte la station S2 à t0+180s au lieu de t0+200s. L'unité de régulation centrale ordonne ensuite, dans un second temps, le ralentissement du véhicule B entre les stations S2 et S3 par rapport à la vitesse prévue dans les conditions nominales de fonctionnement de sorte que le véhicule B quitte la station S3 à l'instant t0+300s initialement prévu.When the number of passengers ascending in the vehicle B at the station S 1 is such that the vehicle B is in an overload condition, the central control unit then automatically receives an overload signal from the vehicle B, this overload signal being developed by the vehicle B from load sensors present on its bogies. On the basis of this information, the central control unit orders the departure of the overloaded vehicle B from the station S1 at the scheduled time but orders, firstly, the vehicle B to accelerate between the stations S1 and S2. beyond the acceleration provided in the nominal operating conditions so that the vehicle B arrives 20 seconds in advance at the station S2 and leaves the station S2 at t 0 + 180s instead of t 0 + 200s. The central control unit then orders, in a second step, the slowing down of the vehicle B between the stations S2 and S3 with respect to the speed provided under the nominal operating conditions so that the vehicle B leaves the station S3 at the same time. moment t 0 + 300s initially planned.

Par cette régulation, l'intervalle de temps séparant les instants de départ des véhicules A et B de la station S2 sera de 80 secondes au lieu de 100 secondes, ce qui aura pour conséquence réduire le nombre de personnes parvenant sur le quai de la station S2 durant cet intervalle de temps et donc de faire monter moins de personnes qu'en temps normal dans le véhicule B au niveau de la station S2. A l'inverse, au niveau de la station S2, l'intervalle de temps séparant l'instant de départ du véhicule C par rapport au véhicule B précédent sera de 120 secondes au lieu de 100 secondes en temps normal, ce qui laissera plus de temps aux personnes pour parvenir sur le quai d'embarquement et donc augmentera le nombre de personnes susceptibles de monter dans le véhicule C à la station S2. Le résultat du procédé de régulation selon l'invention sera un transfert indirect du nombre de passagers du véhicule B vers le véhicule C.By this regulation, the time interval separating the start times of the vehicles A and B of the station S2 will be 80 seconds instead of 100 seconds, which will result in reducing the number of people arriving on the platform of the station S2 during this time interval and thus to raise less people than normal in the vehicle B at the station S2. Conversely, at the station S2, the time interval separating the departure time of the vehicle C from the previous vehicle B will be 120 seconds instead of 100 seconds in normal time, which will leave more than time for people to reach the boarding platform and therefore increase the number of people who can get into vehicle C at station S2. The result of the regulation process according to the invention will be an indirect transfer of the number of passengers from vehicle B to vehicle C.

La figure 3 représente, à titre d'exemple, une variante de réalisation du procédé de régulation selon l'invention dans laquelle lorsqu'un véhicule est en état de surcharge au niveau d'une station d'arrêt, on prolonge le temps d'arrêt du véhicule précédant le véhicule surchargé au niveau de la station d'arrêt suivante de sorte que ce véhicule quitte cette station en retard sur l'horaire initialement prévu, la vitesse du véhicule retardé étant ensuite augmentée dans son parcours jusqu'à la prochaine station afin que ce dernier quitte cette station à l'horaire initialement prévu. Dans cet exemple, les conditions nominales de fonctionnement du système de transport sont identiques à celles décrites précédemment, c'est à dire que l'intervalle de temps entre les voitures A, B, et C en condition normale est de 100 secondes.The figure 3 represents, by way of example, an alternative embodiment of the control method according to the invention in which when a vehicle is in an overload condition at a stopping station, the vehicle stopping time is prolonged preceding the overloaded vehicle at the next stop station so that the vehicle leaves this station late on the schedule initially planned, the speed of the delayed vehicle then being increased in its path to the next station so that this last leaves this station on the schedule initially planned. In this example, the nominal operating conditions of the transport system are identical to those described above, ie the time interval between cars A, B, and C under normal conditions is 100 seconds.

Ainsi, dans les conditions nominales de fonctionnement, c'est à dire lorsque aucun véhicule n'est en étatde surcharge, l'unité de régulation centrale commande la marche des véhicules A, B et C afin que :

  • le véhicule A quitte la station S1 à t0, la station S2 à t0+100s et la station S3 à t0+200s ;
  • le véhicule B quitte la station S1 à t0+100s, la station S2 à t0+200s et station S3 à t0+300s ;
  • le véhicule C quitte la station S1 à t0+200s, la station S2 à t0+300s et station S3 à t0+400s.
Thus, under nominal operating conditions, that is to say when no vehicle is in overload condition, the central control unit controls the operation of vehicles A, B and C so that:
  • vehicle A leaves station S1 at t 0 , station S2 at t 0 + 100s and station S3 at t 0 + 200s;
  • vehicle B leaves station S1 at t 0 + 100s, station S2 at t 0 + 200s and station S3 at t 0 + 300s;
  • the vehicle C leaves the station S1 at t 0 + 200s, the station S2 at t 0 + 300s and station S3 at t 0 + 400s.

Lorsque le nombre de passagers montant dans le véhicule B au niveau de la station S1 est tel que véhicule B se trouve dans un état de surcharge, un signal de surcharge est envoyé automatiquement par le véhicule B à l'unité de régulation centrale qui modifie alors la marche du véhicule A en prolongeant son arrêt dans la station S2 jusqu'à l'instant t0+120 au lieu de t0+100 initialement prévu. Le véhicule A quitte ensuite la station S2 à l'instant t0+120 et l'unité de régulation centrale ordonne un déplacement accéléré du véhicule A entre les stations S2 et S3 de sorte que le véhicule A arrive et parte de la station S3 à l'horaire initialement prévu. Les autres véhicules, et notamment les véhicules B et C poursuivent, leur route sans modification d'horaire.When the number of passengers ascending in the vehicle B at the station S1 is such that the vehicle B is in an overload condition, an overload signal is automatically sent by the vehicle B to the central control unit which then modifies the journey of the vehicle A by prolonging its stop in the station S2 up to the instant t 0 +120 instead of t 0 +100 initially provided. Vehicle A then leaves station S2 at time t 0 +120 and the central control unit orders an accelerated movement of vehicle A between stations S2 and S3 so that vehicle A arrives and leaves station S3 at the schedule initially planned. The other vehicles, and in particular vehicles B and C, continue on their route without any change of schedule.

Il résulte de cette régulation, qu'au niveau de la station S2, l'intervalle de temps séparant le départ du véhicule B du départ du véhicule A précédent est réduit à 80 secondes au lieu de 100 secondes dans les conditions nominales de fonctionnement. Il s'ensuit une réduction du nombre de personnes susceptibles de parvenir sur le quai de la station S2 durant ce délai et donc une réduction du nombre personnes montant dans le véhicule B au niveau de la station S2. A l'inverse, l'intervalle de temps séparant le départ du véhicule A de la station S2 du véhicule le précédent est porté à 120 secondes au lieu de 100 secondes en temps normal, ce qui a pour conséquence d'augmenter le nombre de personnes susceptibles d'être présentes sur le quai de la station S2 et de monter dans le véhicule A. Il en résulte un transfert indirect de la charge de voyageurs du véhicule B vers le véhicule AAs a result of this regulation, at the station S2, the time interval separating the departure of the vehicle B from the departure of the preceding vehicle A is reduced to 80 seconds instead of 100 seconds under the nominal operating conditions. This results in a reduction in the number of people likely to arrive on the platform of the station S2 during this period and thus a reduction in the number of people going up in the vehicle B at the station S2. Conversely, the time interval separating the departure of the vehicle A from the station S2 of the preceding vehicle is increased to 120 seconds instead of 100 seconds in normal time, which has the consequence of increasing the number of people likely to be present on the platform of the station S2 and to climb in the vehicle A. This results in an indirect transfer of the passenger load from the vehicle B to the vehicle A

Le procédé de régulation selon l'invention présente l'avantage de permettre une meilleure répartition des passagers dans les véhicules lorsque se produit un afflux soudain de voyageurs sur le quai d'une gare. Par ailleurs, le procédé de régulation selon l'invention présente l'avantage, en utilisant la mesure de la masse du véhicule pour estimer le nombre de passagers présents dans le véhicule, de pouvoir être mise en oeuvre à très faible coût, puisque des capteurs de masse équipent habituellement les bogies des véhicules pour des questions de sécurité, l'information fournie par ces capteurs pouvant avantageusement être exploitée par le procédé de régulation sans faire appel à des capteurs supplémentaires.The control method according to the invention has the advantage of allowing a better distribution of passengers in vehicles when there is a sudden influx of passengers on the platform of a station. Furthermore, the regulation method according to the invention has the advantage, by using the measurement of the mass of the vehicle to estimate the number of passengers present in the vehicle, to be able to be implemented at very low cost, since sensors The information provided by these sensors can advantageously be used by the control method without using additional sensors.

Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple. Ainsi, le procédé de régulation pourra agir différemment sur la marche des véhicules pour obtenir une réduction du nombre de passagers susceptibles de monter dans les véhicules surchargés.Of course, the invention is not limited to the embodiment described and illustrated which has been given by way of example. Thus, the control method may act differently on the operation of vehicles to obtain a reduction in the number of passengers likely to climb in overloaded vehicles.
