Dynamic Vehicle Reassignment in Platoon Transit Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for managing fluctuating demand in transportation systems, such as railroads, often lead to inefficient vehicle utilization and passenger exclusion due to insufficient seating, as they do not effectively redistribute vehicles between high and low demand areas.
Innovation Solution
A platoon traffic system with an operation management apparatus that dynamically reassigns vehicles between platoons based on passenger demand, allowing leading and succeeding vehicles to adjust their schedules and routes to optimize passenger transport capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the number of spare vehicles is increased to provide for a fluctuation in demand, then sufficient seating capacity is available for concentration of reservations, but vehicle operational efficiency is degraded
Solution Approach 1:
The patent implements dynamic reassignment of vehicles between platoons based on real-time passenger demand. Vehicles are not fixed to specific routes but are dynamically transferred between platoons operating on different routes, allowing the system to adapt to fluctuating demand patterns without increasing the total number of vehicles.
Solution Approach 2:
The system changes operational parameters by adjusting platoon compositions and vehicle assignments based on demand metrics. When demand fluctuates on certain routes, the control device recalculates and modifies which vehicles belong to which platoons, effectively changing the operational configuration to match current demand conditions.
2Ease of operation
If vehicles are fixed to specific routes, then operational simplicity is maintained, but ability to cope with fluctuating demand is reduced
Solution Approach 1:
The system incorporates feedback mechanisms where the control device continuously monitors passenger demand on different routes and uses this information to make real-time adjustments to vehicle assignments. This feedback loop allows the system to maintain operational simplicity through automated control while adapting to changing demand conditions.
Solution Approach 2:
The control device acts as an intermediary between fixed route structures and dynamic demand patterns. It manages the complex reassignment logic and communicates adjusted schedules to vehicles and stations, shielding the operational system from complexity while enabling flexible response to demand fluctuations.

AI summary
A small number of vehicles are efficiently utilized to cope with a fluctuating demand. A platoon traffic system includes a plurality of platoons including vehicles 111 to 113 and 121 to 125 on and from which passengers board and exit, and an operation management apparatus 101 setting an operation schedule including assignment of the vehicles 111 to 113 and 121 to 125 to the plurality of platoons and managing operation of the plurality of platoons. The vehicles 111 to 113 and 121 to 125 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 111 to 113 and 121 to 125, and addition and reduction of vehicles belonging to the platoon are enabled. The operation management apparatus 101 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 on a basis of the boarding request and numbers of passengers allowed to board the vehicles 111 to 113 and 121 to 125.
