Vehicle Travel Plan Controller Railway Track Utilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to enable vehicles to travel on railway tracks without obstructing train operations, allowing for effective use of railway tracks as a travel route while ensuring safe and efficient vehicle movement.
Innovation Solution
A management system that determines suitable railway tracks for vehicle travel based on current position, destination, and railway operation schedules, creating travel plans that avoid interfering with train operations, and includes a control system for autonomous vehicle travel and mode-specific control of vibration damping and collision avoidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a vehicle travels on a railway track, then the utilization of the railway track as a travel route is improved, but the risk of obstructing train operations increases
Solution Approach 1:
The management system continuously acquires railway operation schedules and monitors train positions in real-time. The controller receives feedback about train operations and uses this information to dynamically adjust vehicle travel plans, ensuring the vehicle does not obstruct train operations while maximizing railway track utilization.
Solution Approach 2:
The system acquires railway operation schedules in advance and performs preliminary determination of whether the vehicle can travel on the railway track without obstructing train operations. Travel plans are created beforehand with scheduled departure and arrival times that are coordinated with train operations, preventing conflicts before they occur.
2Measurement precision
If the controller determines route usability based on railway operation schedules, then the accuracy of travel plan creation is improved, but the time required for route determination increases
Solution Approach 1:
The controller performs determination of route usability only when necessary - specifically when a railway track is identified as a potential travel route. The system acquires railway operation schedules selectively for route candidate tracks rather than all possible routes, achieving accurate determination without excessive time consumption.
3Productivity
If the vehicle travels on a railway track during peak train operation hours, then the efficiency of vehicle travel is improved, but the likelihood of obstructing train operations increases
Solution Approach 1:
The travel plan is created dynamically based on the acquired railway operation schedule. The controller adjusts the vehicle's departure time, arrival time, and speed profile to match the dynamic conditions of train operations. This allows the vehicle to travel efficiently on railway tracks during peak hours by adapting its schedule to avoid conflicts with trains.

AI summary
A management system according to the present disclosure is a management system that manages a travel plan of a vehicle that is capable of traveling on a road and a railway track, and includes controller that creates the travel plan of the vehicle. In a case where there is a route candidate track that is a railway track that is possibly used as a travel route of the vehicle, the controller acquires a railway operation schedule for the route candidate track, and determines whether the route candidate track can be used as the travel route of the vehicle, based on the operation schedule. In the case where the route candidate track can be used as the travel route of the vehicle, the controller creates a travel plan according to which the vehicle travels along the travel route including the route candidate track.
