Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If unmanned autonomous travel is implemented on general roads, then transportation efficiency is improved, but safety problems arise
Solution Approach 1:
The travel route is divided into two distinct sections: an unmanned autonomous travel section (toll road) and a manned travel section (general road). This segmentation allows each section to use the most appropriate driving mode for its characteristics, improving overall safety while maintaining transportation efficiency.
Solution Approach 2:
A driver boarding point serves as an intermediary transition point between the unmanned autonomous travel section and the manned travel section. The vehicle transitions from autonomous to manual control at this intermediate location, ensuring safe handover while maintaining continuous transportation flow.
2Adaptability or versatility
If a mixed transportation system with manned and unmanned sections is created, then adaptability to different road conditions is improved, but system complexity increases
Solution Approach 1:
The transportation system is segmented into distinct operational zones (unmanned section and manned section) with clear boundaries. This simplifies the control logic by allowing the system to switch between predetermined modes rather than managing continuous transitions, reducing overall system complexity.
Solution Approach 2:
The travel plan is prepared in advance with predetermined unmanned and manned sections defined before the journey begins. This preliminary configuration reduces real-time decision-making complexity, as the system only needs to follow the pre-planned mode transitions rather than dynamically determining them during travel.
3Reliability
If travel plans are adjusted based on traffic events, then transportation reliability is improved, but plan management complexity increases
Solution Approach 1:
The transportation management apparatus continuously monitors traffic events in the unmanned autonomous travel section and uses this feedback to dynamically adjust travel plans and driving plans. This closed-loop control ensures reliable transportation by responding to actual conditions while maintaining systematic plan management.
Solution Approach 2:
Multiple travel plans and driving plans are prepared in advance for different traffic scenarios. When a traffic event occurs, the system selects from these pre-prepared alternatives rather than creating new plans in real-time, reducing the complexity of plan management while maintaining reliability.
Data Source
AI summary
A transport management device and a transport management method generate a travel plan and a driving plan. The transport management device manages a transport system in which goods and the like are transported by causing, on the basis of the travel plan, a vehicle to travel autonomously and without crew in a crewless autonomous travel section leading to a boarding point for a driver, and then having the driver drive the vehicle from the boarding point on the basis of the driving plan. The transport management device predicts a state of traffic in the crewless autonomous travel section, creates the travel plan and the driving plan, and changes the travel plan and the driving plan of the vehicle traveling in the crewless autonomous travel section in accordance with a traffic event occurring in the crewless autonomous travel section.
