Cell Phone Wrong-Way Detection via Radio Beacon Sequence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for detecting drivers traveling in the wrong direction on highways require special devices installed in vehicles and beacons along the road, limiting their coverage area and effectiveness.
Innovation Solution
A system using radio beacons arranged along roads that emit identifiers, which can be received by cell phones to determine the vehicle's direction of travel, allowing for widespread detection and warning of incorrect direction without the need for special vehicle-installed devices, utilizing the widespread distribution of cell phones and commercially available beacons.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If special devices are installed in vehicles and beacons are placed along the road to detect wrong-way driving, then detection reliability is improved, but device complexity and coverage area are limited
Solution Approach 1:
The invention utilizes cell phones that drivers already carry in their vehicles, which automatically perform detection functions without requiring special installation. The cell phone's existing radio receiver and processor are used to receive beacon identifiers and determine travel direction, making the system self-service and eliminating the need for dedicated detection devices in vehicles.
Solution Approach 2:
The system uses cell phones, which are universal devices already present in most vehicles, to perform multiple functions including wrong-way detection, positioning, and warning. The radio beacons also serve multiple purposes by providing identifiers that enable direction determination and potential other communication functions.
2Area of stationary object
If special devices are installed in a large number of cars to ensure sufficient detection coverage, then detection coverage is improved, but ease of operation and deployment difficulty increase
Solution Approach 1:
The system leverages the widespread distribution of cell phones that drivers already possess, eliminating the need for mandatory installation campaigns. Since cell phones are universally carried, the system automatically achieves wide coverage without requiring active deployment in each vehicle.
Solution Approach 2:
The invention uses cell phones as intermediaries between the radio beacons and the detection system. The cell phone acts as a mediator that receives beacon signals and processes direction information, enabling coverage expansion without direct vehicle-system integration.
3Measurement precision
If radio beacons are arranged along the road to emit identifiers for direction determination, then measurement precision of travel direction is improved, but manufacturing cost and device complexity increase
Solution Approach 1:
The radio beacons are designed as simple, low-cost devices that can be easily manufactured and deployed. Each beacon emits identifiers and can be placed along roadways without complex installation requirements, enabling precise direction determination through affordable infrastructure.
Solution Approach 2:
The system divides the road into sections with individual radio beacons placed at specific locations. Each beacon emits unique identifiers that, when received in sequence by the cell phone, enable precise determination of travel direction through pattern recognition.

Implementation Method 1
providing an arrangement of radio beacons along a lane in a section of a road; emitting identifiers from the radio beacons that are arranged along the lane; when the vehicle travels through the section of road, receiving with a radio receiver in the vehicle (e.g., cell phone, smart phone), the emitted identifiers of the radio beacons in succession
Data Source
AI summary
A method for detecting the direction of travel of and for determining travel in the wrong direction by a vehicle which is moving on a lane in a section of road. Identifiers are respectively emitted by an arrangement of radio beacons which are arranged along the lane. When the vehicle travels through the section of road, a radio receiver, in particular a cell phone device, which is arranged in the vehicle, successively receives the emitted identifiers of the radio beacons. The actual direction of travel of the vehicle is determined on the basis of the sequence of the successively received identifiers.
