Ride-Hailing Pickup Interface With Traffic Light ETA Cues
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current online ride-hailing platforms do not accurately display the traveling status of drivers, making it difficult for passengers to estimate their arrival time due to insufficient traffic light information.
Innovation Solution
A method and apparatus that display the status of the nearest traffic light to the driver on a passenger's interface, including its light-on status and countdown, to help passengers accurately estimate the driver's arrival time by considering the traffic light's impact on the journey.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traffic light information is not displayed, then the interface remains simple, but the arrival time estimation accuracy deteriorates
Solution Approach 1:
The patent segments the driver's journey into multiple road sections based on traffic light locations. Each road section is analyzed independently to determine if traffic light status affects arrival time estimation. This segmentation allows the system to selectively display traffic light information only for relevant sections, improving accuracy without overwhelming the interface with unnecessary data.
Solution Approach 2:
The patent adds a temporal dimension to the spatial display by showing not only the location of traffic lights but also their current status (red/green/yellow) and countdown timing. This multi-dimensional information (position + time + status) enables passengers to understand both where the driver is and what traffic conditions ahead will affect arrival time.
2Measurement precision
If traffic light information is displayed, then arrival time estimation accuracy improves, but the device complexity increases
Solution Approach 1:
The patent applies local quality by displaying traffic light information selectively rather than uniformly. Traffic light status is displayed only for road sections where the light status significantly impacts arrival time estimation. The interface adapts its information density based on the specific journey context, showing detailed traffic light data when relevant and simplifying when not needed.
Solution Approach 2:
The patent uses partial action by displaying only the essential traffic light information needed for accurate arrival time estimation. Rather than showing all possible traffic parameters, the system selectively displays traffic light status and timing for key intersections that directly affect the estimated arrival time, avoiding information overload while maintaining accuracy.
3Measurement precision
If real-time traffic light status is monitored, then the information accuracy improves, but the energy consumption increases
Solution Approach 1:
The patent implements periodic monitoring of traffic light status rather than continuous monitoring. The system checks traffic light status at intervals and updates the display when changes occur that affect arrival time estimation. This periodic approach maintains information accuracy while reducing the energy consumption associated with constant real-time monitoring.

AI summary
An information processing method includes: displaying a waiting interface at a pick-up waiting stage, the waiting interface displaying a location identifier of a service provider and a traveling route from the service provider to a pick-up point, the traveling route including a first location where a first traffic light is located, and the first traffic light being a traffic light nearest to the service provider, a traffic light having a distance with the service provider less than a first distance threshold, or a traffic light whose distance from the service provider is less than a preset threshold in a traveling direction of the service provider; displaying status information of the first traffic light on the waiting interface in response to the service provider satisfying a target condition; and after the service provider passes by the first location, eliminating the status information of the first traffic light on the waiting interface.
