Roadside Device State Detection for Pedestrian and Driver Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roadside devices lack the capability to effectively monitor and notify pedestrians and drivers about the operating state of vehicles with communication functions, particularly in areas like intersections or crosswalks, and do not provide appropriate measures when malfunctions occur.
Innovation Solution
A roadside device equipped with a notification unit and a control unit that determines its operating state and performs tailored notifications to pedestrians, drivers, or control centers using visual, auditory, and communication means to alert them of the device's status and prompt necessary actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If roadside devices monitor vehicles with communication functions, then vehicle monitoring capability is improved, but the ability to notify pedestrians and drivers about device operating state deteriorates
Solution Approach 1:
The roadside device is designed to perform multiple functions: it monitors vehicles with communication functions using reception units, determines its own operating state using determination units, and notifies pedestrians and drivers through notification units. This multi-functional design resolves the contradiction by enabling the device to both monitor vehicles and provide notifications simultaneously without compromising either capability
2Reliability
If roadside devices provide comprehensive notifications, then safety information delivery is improved, but device complexity increases
Solution Approach 1:
The notification system is segmented into multiple independent notification units, each responsible for a specific notification function. The determination unit divides the operating state into distinct categories (normal operation, abnormal operation, maintenance required), and different notification units are activated based on the determined state. This segmentation reduces overall system complexity by creating modular, manageable components while maintaining comprehensive safety information delivery
3Loss of information
If roadside devices monitor multiple operating states, then operational awareness is improved, but response time deteriorates
Solution Approach 1:
The determination unit continuously monitors and determines the operating state in advance, categorizing it into predefined states (normal operation, abnormal operation, maintenance required) before actual issues arise. This preliminary determination allows the notification units to be pre-configured and immediately activated when specific states are detected, reducing response time while maintaining comprehensive operational awareness
Data Source
AI summary
The disclosure relates to a roadside device and a method for providing mobility-as-a-service. The roadside device includes a notification unit and a control unit. The control unit determines an operating state of the roadside device, and performs a notification process to the notification target person according to the determined operating state.
