A railroad system includes a plurality of trains and an operation management device. The operation management device manages operation of a subject train that is at least one of the plurality of trains. The operation management device includes a calculation unit and a communication unit. The calculation unit calculates a target arrival time at which the subject train is to arrive at a next station, upon occurrence of an arrival delay of a preceding train at the next station, the preceding train being a train among the plurality of trains and running ahead of the subject train; and, upon arrival of the preceding train at the next station, calculates a target arrival time at which the subject train is to arrive at the next station. The communication unit transmits, to the subject train, information on the target arrival time calculated by the calculation unit.

Provided are a control method, a vehicle frame, a power driving assembly and a vehicle. The vehicle frame is configured to be connected with the power driving assembly, and the vehicle frame is provided with a manipulation assembly and a controller for controlling the power driving assembly. The control method includes that: after the vehicle frame is connected to the power driving assembly and a communication connection is established between the controller and the power driving assembly, the controller detects a manipulation instruction from the manipulation assembly; and in response to detecting the manipulation instruction from the manipulation assembly and determining that the manipulation instruction corresponds to the power driving assembly, the controller generates, according to the manipulation instruction, a control instruction for controlling the power driving assembly, and sends the control instruction to the power driving assembly.

A ground base device includes a schedule timetable storage unit storing a received schedule timetable periodically transmitted from the central control device; a departure-obstructed condition determination unit determining whether a departure-obstructed condition of a train is resolved and outputting departure-obstructed condition cancel signal when the departure-obstructed condition is resolved; a departure time control unit outputting departure-time appropriate signal when current time is departure time based on the schedule timetable upon receiving the departure-obstructed condition cancel signal; a departure interval control unit outputting departure-interval appropriate signal when intervals between the train and preceding and following trains are a threshold value or more upon receiving the departure-time appropriate signal; and a departure instruction signal output unit outputting a departure instruction signal upon receiving the departure-interval appropriate signal, and, when the central control device fails, the departure time control unit uses the schedule timetable received when the central control device is normal.

A powering pattern representing velocity of a vehicle at each position of a powering interval in a braking delay period between a timing at which the vehicle exceeds allowable velocity and a braking timing at which the vehicle starts to brake, and a coasting pattern representing velocity of the vehicle at each position of a coasting interval subsequent to the powering interval in the braking delay period are calculated after calculating a braking pattern representing velocity of the vehicle in a braking interval, which is a running interval subsequent to the coasting interval and which occurs between a position of the vehicle at the braking timing and a target position for controlling the vehicle to run at predetermined velocity or less, wherein an acceleration characteristic depending on velocity of the vehicle is used to calculate at least the powering pattern.

A ground control device includes: a location information acquiring unit to acquire location information indicating a train location from a train through a ground wireless device; an on-track information acquiring unit to acquire on-track information indicating whether or not the train is present on a track in a predetermined zone; and a control unit to set a protection zone for the train when the location information acquiring unit cannot acquire the location information, and to cancel a portion of the protection zone on the basis of the on-track information acquired by the on-track information acquiring unit when the train has run in an emergency driving mode.

A platoon traffic system includes a plurality of platoons including vehicles on and from which passengers board and exit, and an operation management apparatus setting an operation schedule including assignment of the vehicles to the plurality of platoons and management thereof. The vehicles in each of the platoons integrally operate in accordance with the operation schedule along a track including boarding and exiting points where passengers board and exit the vehicles The operation management apparatus accepts a boarding request for the vehicles, the request specifying the boarding and exiting points, and changes the operation schedule to reassign the vehicles belonging to the plurality of platoons, among the platoons based on the boarding request and numbers of passengers allowed to board the vehicles.
