The historical traffic data may include historical site traffic, historical site pick-up and pick-up numbers, and the like. The target date may be any day in the future, and may be, for example, the next day.
In addition, historical passenger flow volume data and a target date of a target line can be input into a neural network model for predicting passenger flow volume to obtain the passenger flow volume of the target line on the target date; or, the passenger flow of the target line on the target date may be obtained through prediction according to a first preset rule, for example, historical passenger flow data indicates that the passenger flow of the xx station at the five points of friday per week is between 30 and 40, and the passenger flow of the xx station at the five points of friday may be (30 + 40)/2 = 35.
And step 102, determining the expected running information of the vehicle on the target route on the target date according to the predicted passenger flow.
The predicted operation information may include information such as a station, departure time, the number of required vehicles, and predicted time.

The predicted passenger flow volume can be input into a neural network model for predicting predicted operation information to obtain the predicted operation information; or, the predicted operation information may be obtained according to a second preset rule, for example, if the passenger flow of the xx station at the five points of friday is 35, the predicted operation information may satisfy that a vehicle at the five points of friday arrives at the xx station, and the vehicle may accommodate 35 people at the xx station.
In addition, the predicted operation information of the vehicle on the target route on the target date may be stored as a plan. Taking the vehicle as an unmanned connection vehicle as an example, on the target date, the unmanned vehicles with the electric quantity meeting the target line can be screened out from the existing unmanned vehicles before departure, and if the screened unmanned vehicles are less than the required number of vehicles, the screened unmanned vehicles can be used as the unmanned vehicles of the target line, and the available vehicles can be monitored in real time to supplement the unmanned vehicles of the target line.

Taking the target route as the route 1 as an example, when the passenger flow of the route 1 is larger than the passenger capacity of the stop and the road traffic flow is smooth, the departure interval time of the route 1 can be shortened; when the cameras arranged on the line 1 monitor bad weather, the departure interval time of the line 1 can be shortened; when the cameras arranged on the line 1 monitor that accidents, obstacles, construction, temporary control and the like happen to a certain road section, the line of the line 1 can be re-planned. Therefore, in the running process, the vehicle is subjected to scene deployment under a specific scene by combining multipoint real-time video stream data and image recognition capability.
As shown in fig. 2, the decision-making planning and scheduling center issues the predicted operation route and departure time of each time period to the vehicle, and the vehicle runs to the station 1 according to the operation route, and the station can be considered as a station. When the vehicle runs to the platform 1, cameras arranged on a front door and a rear door of the vehicle carry out camera shooting, the cameras and a road side camera on the vehicle upload real-time video stream data to a decision-making planning and dispatching center, the decision-making planning and dispatching center analyzes the video stream data and issues a decision instruction to the vehicle according to the real-time video stream data, and the vehicle sends the state of the vehicle, the current position information of the vehicle, the electric quantity and the number of passengers in the vehicle to the decision-making planning and dispatching center at intervals in the running process.
In addition, taking the vehicle as an unmanned transfer vehicle as an example, for each unmanned transfer vehicle, the relevant information of the unmanned transfer vehicle can be displayed on a monitoring picture of a decision planning and scheduling center, and the monitoring information of the unmanned transfer vehicle can be displayed, wherein the monitoring information comprises camera pictures of the front of the vehicle, the front inside the vehicle, the door, the back inside the vehicle and the platform; the actual running speed and the planned running speed can also be displayed; the current previous station of the unmanned transfer vehicle, the number of passengers getting on the vehicle and the number of the remaining passengers can be displayed; the current next station of the unmanned transfer vehicle, the number of passengers at the next station and the predicted arrival time can be displayed; the number of unmanned transfer vehicles going to the next station and the number of vacant positions can be displayed; the percentage of the number of passengers in the vehicle in a previous period of time to the maximum number of passengers capable of being accommodated in the vehicle can be displayed; the number of the existing or not plug-in vehicles, the total travel of the running route, the estimated total running time and the station number can also be displayed.

wherein, when the station passenger flow volume is consistent with the passenger capacity, the saturation is 1; when the saturation is greater than 1, the passenger flow of the station exceeds the passenger carrying capacity of the current station, and at the moment, the larger the saturation value is, the longer the residence time of the passenger will be; when the saturation is less than 1, the passenger flow of the station is less than the passenger carrying capacity of the current station, and at this time, the smaller the saturation value is, the lower the vehicle passenger carrying rate is, that is, the lower the actual operation efficiency is.
In addition, the traffic flow coefficient may be characterized as a traffic congestion degree or a traffic flow rate, or the like.
