Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to improve the capacity of urban rail transit in coping with sudden large passenger flows, the invention provides a real-time passenger flow oriented operation plan adjusting method based on line topology and online capacity conditions, and provides a new thought and solution for urban rail transit in coping with sudden large passenger flows.
Fig. 1 is a schematic flow chart of a train operation adjustment method provided in an embodiment of the present invention, including:
specifically, the real-time passenger flow situation needs to be acquired for the dynamic adjustment of the running chart facing the real-time passenger flow.
In the embodiment of the invention, the real-time passenger flow data is counted according to a certain time period (namely a preset period) by an AFC system, a video identification technology and a train weighing mode, so that the relevant condition of the real-time passenger flow is obtained.
It should be noted that the preset period is required to meet the current real-time passenger flow data acquisition method and technical level. In one embodiment, real-time inbound and outbound traffic is uploaded every 15min by the AFC system, so the preset period may take 15 min.
And after the real-time passenger flow data is obtained, monitoring whether a line or a road network fluctuates in real time based on the real-time passenger flow data so as to judge whether the real-time passenger flow meets the triggering condition of the early warning of the sudden large passenger flow, and if the real-time passenger flow meets the triggering condition of the early warning of the sudden large passenger flow, indicating that the real-time passenger flow is the sudden large passenger flow.
specifically, if it is determined that the real-time passenger flow meets the triggering condition of the early warning of the sudden large passenger flow, a early warning mechanism of the sudden large passenger flow is triggered, but the online train has certain passenger flow evacuation capacity, and the sudden large passenger flow does not necessarily cause influence within the range of a line or a road network, so when it is determined that the real-time passenger flow meets the triggering condition of the early warning of the sudden large passenger flow, capacity and transportation matching calculation needs to be performed to determine the influence of the real-time passenger flow on the whole line or the road network and judge whether the existing transportation capacity meets the future passenger flow demand.
It should be noted that, in order to perform the capacity matching study, the future predicted passenger flow volume and the passenger flow propagation direction are required as input.
The predicted passenger flow volume and the passenger flow propagation direction are obtained by predicting based on the real-time passenger flow, are related to the specific travel behavior of passengers, and are obtained by predicting specifically, but the invention is not limited.
In the embodiment of the invention, the passenger flow real-time monitoring system is assumed to predict the future passenger flow and the passenger flow propagation direction based on the existing real-time data, and form a driving dynamic adjustment strategy based on the future passenger flow and the passenger flow propagation direction. In one embodiment, the period of predicted passenger flow is 1 hour.
In the embodiment of the invention, when carrying out the capacity and capacity matching, the capacity and capacity matching is carried out in different directions according to the passenger flow propagation direction, and the capacity and the force in the future adjustment period are compared aiming at each passenger flow propagation direction, so that the capacity and capacity matching result in each passenger flow propagation direction can be determined.
specifically, based on the matching result of the transport capacity in each passenger flow propagation direction, if it is judged and found that the existing transport capacity cannot meet the future passenger flow demand, the range influenced by the real-time passenger flow in the whole line or the whole road network is determined according to the passenger flow propagation direction and the existing train operation plan, the influenced passenger flow propagation directions are sorted according to the mismatching degree of the transport capacity, and the passenger flow propagation directions are divided into the directions 1 and 2 …, namely the direction N.
Wherein, the bigger the difference of the transport capacity, the higher the mismatching degree.
And 103, starting from the passenger flow propagation direction with the maximum mismatching degree of the transport capacity, aiming at each influenced passenger flow propagation direction, and according to the occurrence position of the large passenger flow corresponding to the passenger flow propagation direction and the passenger carrying condition of the peripheral on-line trains, adjusting the train operation plan.
Specifically, all affected passenger flow propagation directions are traversed sequentially from the passenger flow propagation direction with the largest mismatching degree of the transport capacity, and for each affected passenger flow propagation direction needing to be adjusted, the occurrence position of the large passenger flow corresponding to the current passenger flow propagation direction and the passenger carrying conditions of the peripheral online trains are considered, and the resources of the in-store trains and the online trains are fully utilized to adjust the train operation plan.
According to the train operation adjusting method provided by the embodiment of the invention, according to the position of the occurrence of the sudden large passenger flow and the online train operation condition, the in-store train and online train resources can be fully utilized, the passenger flow fluctuation can be effectively and efficiently responded, and technical support is provided for dynamically adjusting the operation diagram and improving the automation level of urban rail transit operation scheduling.
Based on the content of the foregoing embodiment, the step 100 monitors real-time passenger flow according to a preset period, and determines whether the real-time passenger flow meets a triggering condition for a large burst passenger flow early warning, including:
according to a preset period, counting real-time passenger flow data, wherein the real-time passenger flow data comprises the following steps: the train passenger flow volume comprises station passenger flow volume, platform passenger flow volume and train carriage passenger flow volume;
comparing the real-time passenger flow data with historical contemporaneous passenger flow data to judge whether the real-time passenger flow meets the triggering condition of sudden large passenger flow early warning;
the triggering conditions of the sudden large passenger flow early warning are as follows: any one of the real-time passenger flow data exceeds the historical contemporaneous passenger flow data by a preset threshold.
Specifically, the real-time passenger flow data is counted according to a certain time period, that is, according to a preset period, and the real-time passenger flow data includes, but is not limited to, an in-and-out passenger flow volume, a platform passenger flow volume, and a train in-car passenger flow volume.
And after the real-time passenger flow data is obtained, comparing the real-time passenger flow data with historical contemporaneous passenger flow data, and monitoring whether the passenger flow of a line or a road network fluctuates in real time, thereby judging whether the real-time passenger flow meets the triggering condition of sudden large passenger flow early warning. The triggering conditions of the early warning of the sudden large passenger flow are as follows: any one of the real-time passenger flow data exceeds the historical contemporaneous passenger flow data by a preset threshold.
In a specific embodiment, in a statistical period, if any one of the real-time passenger flows exceeds 10% of the historical contemporaneous passenger flow data, a sudden large passenger flow early warning mechanism is triggered.
Based on the content of the foregoing embodiment, in the step 103, performing train operation plan adjustment according to the occurrence position of the large passenger flow corresponding to the passenger flow propagation direction and the passenger carrying situation of the peripheral on-line trains, includes:
if the position of the occurrence of the large passenger flow is close to the vehicle section or the parking lot, the train operation plan is adjusted in a mode of increasing empty vehicles;
if the position of a large passenger flow is far away from a vehicle section or a parking lot and the online trains in the same direction have certain passenger digestion capacity, adjusting a train operation plan in a non-transfer station stop-and-go mode to utilize the transport capacity of the online trains in the same direction;
if the position of the large passenger flow is far away from the vehicle section or the parking lot and the reverse direction online train has certain passenger digestion capacity, the train operation plan is adjusted by adopting a reverse direction train passenger clearing and turning back mode so as to utilize the transport capacity of the directional online train; alternatively, the first and second electrodes may be,
if the position of the large passenger flow is far away from the vehicle section or the parking lot and the online train does not have passenger digestion capacity, the passenger arrival amount is limited by adopting a flow control mode.
Specifically, the train operation plan is adjusted according to each passenger flow propagation direction needing to be adjusted, and the sudden large passenger flow is divided into the following four conditions according to the passenger carrying condition of the on-line train at the position where the passenger flow propagation plan occurs and the passenger carrying condition of the on-line train around the position where the passenger flow propagation direction occurs:
(1) large passenger flows occur close to the vehicle segment or parking lot:
the increase of empty vehicles is the most direct and effective method for evacuating large passenger flows, and when the position where the large passenger flows are close to a vehicle section or a parking lot, the train in the garage can quickly reach the position where the sudden large passenger flows are located. In the embodiment of the invention, the position which can be reached within 15 minutes is considered to be close to the train section in consideration of the preparation and delivery time of the train in the garage. In this case, the passenger flow is evacuated in such a way that the passenger flow is directly added from the vehicle section or the parking lot and reaches the position of the large passenger flow.
In one embodiment, after the train operation plan is adjusted by increasing empty vehicles if the position of occurrence of the large passenger flow is close to the vehicle section or the parking lot, the method further includes:
if the number of the empty trains needing to be increased exceeds the number of the trains in the garage, the capacity of the online trains in the same direction is utilized in a non-transfer station inter-station jumping-stop mode, or the passenger arrival amount is limited in a flow control mode.
In particular, the number of in-depot trains that can be used is limited in actual operation. If the number of the required trains exceeds the number of the trains in the storage, other modes are needed to assist in evacuating large passenger flows, for example, the transportation capacity of the trains is planned in the same direction by adopting a mode of jumping and stopping at the stations at non-transfer stations, or the passenger arrival amount is limited by directly adopting a flow control method, so that the safety of the platform is ensured.
(2) The large passenger flow is far away from the vehicle section or the parking lot, and the trains in the same direction have certain passenger digestion capacity
If the position of the large passenger flow is far away from the vehicle section or the parking lot, the train in the parking lot or the vehicle section cannot arrive at the position of the large passenger flow in time. In order to respond to large passenger flow in time, under the condition that trains in the same direction have certain capacity, the capacity of the on-line trains is utilized, and a mode of train jump stopping is adopted to reserve larger passenger carrying capacity for large passenger flow stations, wherein the scene often occurs in off-peak operation period. In the embodiment of the invention, when the large passenger flow early warning is triggered, the online trains in the same direction adopt a non-transfer station inter-station jumping-stopping mode to reserve the passenger flow evacuation capacity.
In one embodiment, if the large passenger flow occurs at a position far away from the vehicle section or the parking lot and the on-line train in the same direction has certain passenger digestion capacity, the adjusting the train operation plan in a non-transfer station-to-station stop-jump manner so as to utilize the transportation capacity of the on-line train in the same direction further comprises:
adjusting a train operation plan by increasing empty trains; alternatively, the first and second electrodes may be,
and if the position where the large passenger flow occurs is a turn-back station, adjusting the train operation plan in a way of turn-back in midway or flow control.
Specifically, in some train situations, because passenger digestion capacity of an on-line train is limited, it is still necessary to add empty cars to supplement capacity, by which the train operation plan is adjusted. If the position of the large passenger flow is a turn-back station and no vehicle section or parking lot exists, the train operation plan needs to be supplemented and adjusted in a midway turn-back or flow control mode.
(3) The large passenger flow is far away from the vehicle section or the parking lot, and the train in the opposite direction has certain passenger digestion capacity
The position of occurrence of the large passenger flow is far away from the vehicle section or the parking lot, the passenger flow in the same direction is large, and the train has no passenger carrying capacity to evacuate the large passenger flow. If the train running in the opposite direction has a certain passenger digestion capacity, the transportation capacity in the large passenger flow broadcasting direction can be rapidly supplemented by adopting a mode of clearing and turning back the train in the opposite direction, and the scene usually occurs in an unbalanced passenger flow scene, such as tidal passenger flow or downward large passenger flow. Under the scene, whether the vehicle needs to be added from the vehicle section or the parking lot to supplement the online transportation capacity can be selected according to the actual situation, and the balanced operation interval is maintained.
(4) The large passenger flow occurs at a place far from the vehicle section or parking lot and the on-line train has no passenger digestion ability
The large traffic is far away from the vehicle section or parking lot, and the surrounding on-line trains are in a saturated state without carrying capacity, in which case the urban rail transit system is in a state of high load operation, which often occurs in the peak operation period. In this case, the system adjustment capability is very limited, and at this time, the passengers are restricted from entering the station by using a station current limiting method or inducing the passengers to use other transportation methods so as to avoid danger.
Different adjustment strategies are adopted for different situations, but in actual operation, different modes can be combined with each other to achieve better effect.
The train operation adjusting method provided by the embodiment of the invention combines the passenger flow occurrence position and the online passenger flow condition, divides different conditions, and provides the train operation adjusting strategy specifically adopted under different conditions, the adjusting method is simple and efficient, the adjusting strategy is generated more quickly, the application requirements of a dispatching system are met better, important support is provided for dispatching personnel, and the purposes of quickly responding to passenger flow change, relieving station pressure and improving passenger service quality are finally achieved.
Based on the content of the above embodiment, the train operation adjusting method further includes:
and carrying out capacity matching on the adjusted train operation plan to judge whether the adjusted train operation plan meets the future passenger flow requirement.
Specifically, after the train operation adjustment in all passenger flow propagation directions is completed, the capacity and the transportation capacity of the adjusted train operation plan are matched to judge whether the adjusted train operation plan meets the future passenger flow requirement, and if the adjusted train operation plan meets the future passenger flow requirement, the train operation plan is updated, and the real-time passenger flow monitoring in the next period is performed.
The train operation adjusting method provided by the embodiment of the invention can effectively improve the automation level of train dispatching, improve the handling efficiency of sudden large passenger flows and improve the operation service quality.
