Engineering Contradiction Analysis
1Reliability
If a traffic signal system uses traditional high-order control apparatus to manage intersection traffic, then traffic flow can be controlled according to pre-established rules, but the system fails when communication between the traffic signal and control apparatus is disrupted
Solution Approach 1:
The traffic signal system performs self-diagnosis and self-control by analyzing images captured by its own imaging apparatus. The control unit determines vehicle presence, direction, and collision risk autonomously without requiring external control signals, enabling the system to maintain functionality when communication with high-order control apparatus is disrupted.
Solution Approach 2:
The imaging apparatus serves as an intermediary between the traffic signal and the control unit. By capturing images of vehicles and providing visual information, it enables the control unit to make intelligent decisions about signal control and collision prevention without relying on complex communication protocols with external control apparatus.
2Reliability
If the traffic signal system adds imaging apparatus and intelligent analysis capabilities, then collision prevention capability is improved, but device complexity increases
Solution Approach 1:
The imaging apparatus and control unit serve multiple functions: they detect vehicle presence, determine vehicle direction, assess collision risk, and control signal display. This multi-functionality reduces the need for separate dedicated devices for each function, thereby limiting the increase in overall system complexity while enhancing collision prevention capabilities.
Solution Approach 2:
The control unit is integrated with the imaging apparatus and signal control functions. By merging these components into a unified system where the control unit processes image data and directly controls signal output, the patent reduces structural complexity compared to having separate independent systems for imaging, analysis, and control.
3Speed
If the system captures and analyzes images in real-time to prevent collisions, then response speed to potential collisions is improved, but energy consumption increases
Solution Approach 1:
The imaging apparatus captures images at periodic intervals rather than continuously. The control unit analyzes these periodic images to detect vehicle presence and potential collision risks. This periodic operation reduces energy consumption compared to continuous imaging and real-time processing, while still maintaining adequate response speed for collision prevention.

AI summary
A vehicle includes a mobile communication device, where the mobile communication device is connected to a driving unit of the vehicle and controls a traveling speed of the vehicle, which is traveling toward an intersection, in order to avoid a collision of the vehicle at the intersection by receiving analysis result information, which is based on image information from an imaging apparatus provided near the intersection, from an information control device.
