Bus Stop Selection and AV Dispatch for Congestion-Free Transfers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mass transportation systems face challenges in providing seamless transfers to autonomous vehicles due to predefined routes and congestion, leading to inefficient passenger transfers and overcrowding.
Innovation Solution
Incorporating a stop selector and dispatcher in mass transportation vehicles that allow passengers to choose alternative stops to avoid congestion and reduce overcrowding, with an autonomous vehicle dispatch management system that books transfers and adjusts routes accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If passengers select destination stops along the predefined operation route, then transfers to autonomous vehicles can be achieved, but congestion and overcrowding occur at popular destination stops
Solution Approach 1:
The system performs preliminary actions by notifying passengers in advance about alternative stops and congestion conditions before they reach their original destination stops. The notification is sent proactively, allowing passengers to change their disembarkation plans before arriving at congested areas, thus preventing overcrowding while maintaining transfer convenience
Solution Approach 2:
The system dynamically adjusts destination stop recommendations based on real-time congestion information and autonomous vehicle availability. Instead of fixed destination stops, the system provides dynamic alternative stop suggestions that adapt to current traffic conditions and vehicle dispatch status, resolving the contradiction between maintaining popular destinations and avoiding congestion
2Stability of the object's composition
If the mass transportation vehicle travels along a predefined operation route, then route stability is maintained, but it cannot avoid congested sections
Solution Approach 1:
The autonomous vehicle acts as an intermediary that bridges the gap between the mass transportation vehicle's fixed route and the passenger's need to avoid congestion. The autonomous vehicle picks up passengers at alternative stops along the stable predefined route and transports them to their final destinations, allowing the mass transportation vehicle to maintain route stability while passengers experience congestion-free travel
Solution Approach 2:
The journey is segmented into two independent parts: the mass transportation vehicle handles the stable predefined route portion, while the autonomous vehicle handles the flexible congestion-avoidance portion. This segmentation allows each vehicle type to operate in its optimal mode - the mass transportation vehicle maintains schedule stability while the autonomous vehicle optimizes for congestion avoidance
3Adaptability or versatility
If passengers are allowed to select any stop as destination, then transfer flexibility is improved, but insufficient time remains to book autonomous vehicle dispatch
Solution Approach 1:
The system performs preliminary dispatch booking actions as soon as the mass transportation vehicle departs from the current stop, well before the passenger reaches the selected destination stop. The autonomous vehicle is booked and dispatched in advance, ensuring that the vehicle is already en route or positioned near the destination when the passenger arrives, thus maintaining both flexibility and sufficient booking time
Solution Approach 2:
The autonomous vehicle dispatch process is rushed through in advance during the mass transportation vehicle's travel time. Instead of waiting until the passenger is ready to transfer, the system expedited the booking and initial dispatch of the autonomous vehicle during the interval between stops, ensuring everything is prepared before the passenger needs to transfer

AI summary
A mass transportation vehicle includes a stop selector and a dispatcher. The stop selector is configured to enable a passenger on the mass transportation vehicle to select a destination stop at which the passenger plans to get off. The dispatcher is configured to book dispatch of an autonomous vehicle to which the passenger transfers after getting off the mass transportation vehicle at the destination stop. The dispatcher sends information about the destination stop to a dispatch management device of the autonomous vehicle as information about a waiting point of the autonomous vehicle.
