Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current intelligent transportation systems lack refined management of road resources, leading to inefficient use and safety issues due to the coarse division of road segments and inaccurate vehicle counting methods, which fail to adapt to varying road lengths and dynamic traffic conditions.
Innovation Solution
The implementation of a lane scheduling method that divides roads into logical segments and lanes, allowing for real-time allocation of resources based on vehicle requests, using a management device that communicates with vehicles to optimize lane usage and adjust density, thereby improving safety and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If natural road segments are used for vehicle counting, then the system is simple to implement, but the vehicle counting accuracy deteriorates due to lane changes on long road segments
Solution Approach 1:
The patent divides natural road segments into multiple logical road segments based on lane change detection zones. Each logical road segment is further divided into multiple logical lanes, creating a hierarchical segmentation structure. This allows the system to track vehicles at a finer granularity level, improving counting accuracy while maintaining manageable system complexity through modular design.
Solution Approach 2:
The patent introduces logical lanes as an intermediary concept between physical road segments and vehicle tracking. By creating virtual lane structures that overlay the physical road, the system can accurately attribute vehicles to specific lanes even when lane changes occur, serving as a mediator that resolves the conflict between simple implementation and accurate measurement.
2Device complexity
If coarse road division is used, then the system complexity is low, but the road resource utilization efficiency deteriorates
Solution Approach 1:
The patent implements multi-level segmentation of roads into logical road segments and logical lanes, enabling fine-grained resource allocation. This segmentation allows the system to manage road resources efficiently by assigning specific logical lanes to vehicles based on their destinations and current positions, thereby improving overall road utilization without overwhelming system complexity.
Solution Approach 2:
The patent introduces dynamic lane assignment where logical lanes are allocated to vehicles based on real-time traffic conditions, vehicle destinations, and current positions. This dynamic approach allows the system to optimize road resource utilization adaptively, adjusting lane assignments as traffic patterns change, thereby improving productivity without requiring a statically complex system.
3Ease of operation
If natural lanes are used without logical segmentation, then the system is easier to operate, but the traffic management precision deteriorates
Solution Approach 1:
The patent creates a virtual copy of the physical road structure in the form of logical lanes and logical road segments. This digital replica mirrors the physical infrastructure but adds the dimension of logical organization based on traffic flow patterns. The copying approach allows the system to maintain ease of operation by working with a simplified virtual model while achieving precise lane usage tracking through the structured logical segmentation.
Solution Approach 2:
The patent adds a logical dimension to the physical road structure by superimposing logical lanes and segments on top of natural lanes. This dimensional enhancement transforms the single-layer physical road model into a multi-layer model that includes both physical and logical attributes, enabling precise lane usage measurement without complicating the operational interface.

AI summary
A lane scheduling method, a method for obtaining lane information, a vehicle, and a management device are provided. The lane scheduling method includes: receiving, by a management device, a road resource allocation request sent by a vehicle, where the road resource allocation request includes at least one road segment identifier, the road segment identifier is used to identify a logical road segment expected to be used by the vehicle, the logical road segment is a logical segment of a road on which the vehicle moves, and the logical segmentation segments a lane included in the road into logical lanes; allocating a road resource to the vehicle based on the road resource allocation request, where the road resource includes at least one logical lane corresponding to the at least one road segment identifier; and sending a lane identifier of the at least one logical lane to the vehicle. In the lane scheduling method, a logical lane is allocated to a vehicle based on a road resource allocation request. Therefore, when there are a lot of vehicles, the management device can allocate road resources globally to implement refined management of vehicles and improve utilization of road resources and safety of moving vehicles.
