Roadside Laser Traffic Jam Detection and Classification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional traffic information systems fail to provide real-time traffic jam information, leading to increased accident risks as drivers are not adequately informed about traffic conditions ahead, particularly distinguishing between simple jams and accident-related jams.
Innovation Solution
An apparatus installed on roads collects weight, vibration, and noise data to determine traffic jams and their types, transmitting this information to vehicles via wireless communication, including distance and type, to display on LED boards, enabling drivers to recognize and respond to traffic conditions in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional display boards and mobile phone services are used to provide traffic information, then traffic condition information can be displayed, but real-time traffic jam information and accident information cannot be provided accurately
Solution Approach 1:
The patent replaces conventional visual display boards and mobile phone text services with a laser-based detection system. The laser transmitter and receiver detect traffic conditions by measuring light reflection from vehicles, enabling real-time detection of traffic jams and accidents with high precision without relying on manual reporting or periodic updates.
Solution Approach 2:
The patent introduces a laser beam as an intermediary between the detection system and vehicles. The laser beam reflects off vehicle surfaces to provide information about traffic conditions, serving as a non-contact mediator that enables real-time detection of vehicle presence, density, and movement without physical interaction with the vehicles.
2Loss of time
If vehicle density monitoring is used to detect traffic accidents, then traffic accidents can be detected in short time, but simple traffic jams and accident-caused traffic jams cannot be discriminated
Solution Approach 1:
The patent applies local quality by using different analysis methods for different traffic conditions. The system analyzes not only vehicle density but also the distribution pattern, movement characteristics, and spatial arrangement of vehicles at specific locations to distinguish between simple traffic jams (where vehicles are evenly distributed) and accident-caused jams (where vehicles are concentrated abnormally near an accident point).
Solution Approach 2:
The patent performs preliminary analysis of traffic patterns by continuously monitoring vehicle density and distribution over time. The system establishes baseline traffic flow characteristics and compares real-time data against these baselines to early detect abnormal conditions, enabling discrimination between normal traffic jams and accident-related jams before they fully develop.
3Device complexity
If users do not receive traffic information on the road ahead, then the information system is simple, but the possibility of traffic accidents increases
Solution Approach 1:
The patent implements a self-service information system where the laser detection infrastructure automatically and continuously provides traffic condition data without requiring user activation or manual input. The system autonomously detects traffic jams and accidents, processes the data, and delivers alerts to users' mobile devices, enabling drivers to receive safety information passively while maintaining system simplicity.
