Relayed On-Demand Video Sharing for Traffic Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current route planning and mapping systems provide limited real-time information about traffic conditions, such as the nature, length, and duration of delays, which can lead to inefficient route changes and increased travel time for drivers.
Innovation Solution
A system that allows vehicles to request and relay video feeds from candidate vehicles equipped with cameras, using a processor to determine suitable vehicles within a predefined distance and transmit recorded video to requesting vehicles, forming an ad-hoc network for on-demand live video coverage of areas of interest.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If continuous video recording and transmission from all vehicles is implemented, then real-time traffic information coverage is improved, but energy consumption and system complexity increase significantly
Solution Approach 1:
The system divides the video transmission task into segments: only candidate vehicles (those closest to the area of interest) are selected to record and transmit video, rather than all vehicles. This segmentation reduces the number of active transmitters and lowers overall energy consumption while maintaining information coverage.
Solution Approach 2:
The system implements partial action by having only a subset of vehicles (candidate vehicles) perform video recording and transmission based on their proximity to the area of interest. This partial participation approach provides sufficient real-time information without requiring full system-wide continuous transmission, thereby reducing energy consumption.
2Loss of information
If video requests are relayed through multiple transceivers in an ad-hoc network, then real-time information delivery is improved, but transmission delay increases
Solution Approach 1:
The system performs preliminary actions by pre-establishing the ad-hoc network infrastructure and maintaining vehicle location tracking before video requests are made. When a video request is received, the system can quickly identify candidate vehicles and initiate transmission without delays associated with network setup or vehicle discovery.
3Device complexity
If a ad-hoc network is formed for on-demand video sharing, then system complexity is reduced compared to continuous transmission, but information delivery reliability may be affected
Solution Approach 1:
The system uses an intermediary server to manage video requests, identify candidate vehicles, and coordinate transmission. This intermediary simplifies the overall system architecture by centralizing control logic while maintaining reliable information delivery through structured request-response protocols and candidate vehicle selection based on proximity to the area of interest.
Data Source
AI summary
A system includes a processor configured to receive a request from a host vehicle for video relating to a location specified in the request. The processor is also configured to determine whether a candidate vehicle receiving the request can provide the request video when the request is received. The processor is further configured to relay the request to a transceiver in wireless communication with the candidate vehicle, if the candidate vehicle cannot provide the requested video, otherwise record and transmit the requested video.
