Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous vehicles face challenges in determining optimal pickup locations due to the complexity of mapped areas and varying pedestrian paths, which can lead to suboptimal routing and rider accessibility issues.
Innovation Solution
The system uses digital map information and sensor data to generate heatmaps of pedestrian walking paths, comparing these with mapped areas to identify suitable pickup locations, and adjusts vehicle operations accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the system uses only digital map information to determine pickup locations, then the routing planning is simpler, but the accuracy of pickup location selection deteriorates due to inability to capture actual pedestrian behavior
Solution Approach 1:
The system merges digital map information with sensor data from multiple vehicles to create a comprehensive pickup location evaluation system. This combination allows the system to maintain routing planning simplicity while significantly improving pickup location selection accuracy by incorporating actual pedestrian behavior data.
Solution Approach 2:
The system introduces sensor data and pedestrian behavior analysis as an intermediary between the digital map information and the final pickup location selection. This intermediary layer processes actual pedestrian movement patterns and integrates them with map data to determine optimal pickup locations without complicating the overall routing planning process.
2Measurement precision
If the system incorporates sensor data from multiple vehicles to generate pedestrian path heatmaps, then the pickup location selection accuracy is improved, but the data processing complexity increases
Solution Approach 1:
The system segments the data processing task into distinct components: sensor data collection from multiple vehicles, pedestrian object classification, trajectory information extraction, and heatmap generation. This segmentation allows each component to be processed independently and efficiently, reducing overall data processing complexity while maintaining high pickup location selection accuracy.
Solution Approach 2:
The system performs preliminary classification of objects as pedestrians and extraction of trajectory information before generating the final heatmap. This preliminary processing organizes raw sensor data into structured format, making the subsequent heatmap generation and pickup location selection more efficient and less complex.
3Ease of operation
If the system compares digital map information with pedestrian heatmaps to identify pickup locations, then the rider accessibility is improved, but the computational requirements increase
Solution Approach 1:
The system applies local quality analysis by comparing digital map information with pedestrian heatmaps only in the specific vicinity of the requested pickup area, rather than processing entire maps. This localized comparison significantly reduces computational energy consumption while maintaining high rider accessibility by focusing resources on relevant geographic areas.

AI summary
The technology involves identifying suitable pickup and drop-off locations based on detected pedestrian walking paths. Mapped areas have specific physical configurations, which may suggest places to pick up or drop off a rider (or a delivery). A walking path heatmap can be generated based on obtained historical and/or real-time pedestrian-related information, which can be obtained by autonomous vehicles driving in areas of interest. Incorporating heatmap information into the evaluation, the system identifies locations for optimized pickup or drop-off in accordance with where pedestrians would likely go. One aspect involves classifying different objects, for instance identifying one or more objects as people who may be walking versus riding a bicycle. Once classified, information about the paths is used to obtain a the heatmap associated with the walking paths.
