Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems face challenges in providing real-time traffic data due to the high cost and limited availability of stationary monitoring sites, which restricts the accuracy and effectiveness of navigation information, especially for all roadways.
Innovation Solution
A distributed traffic sampling and navigation system that intelligently partitions processing between clients and servers, allowing for flexible, geographically expansive, and robust real-time navigation information by controlling sampling rates, geographic regions, and sample distribution, enabling efficient generation and validation of travel routes and estimated travel times without relying on traditional monitoring infrastructures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If stationary monitoring sites are used to provide traffic information, then measurement precision is improved, but device complexity and cost increase significantly
Solution Approach 1:
The patent uses mobile client devices (smartphones, tablets, GPS units) as virtual copies of traditional stationary monitoring sites. These devices contain GPS receivers and sensors that replicate traffic monitoring functionality, transmitting location and traffic data to the server without requiring physical monitoring infrastructure at every location.
Solution Approach 2:
The system enables self-service traffic monitoring by utilizing the existing GPS receivers, processors, and communication capabilities of mobile client devices. Each device independently collects its own navigation information and traffic data, then contributes this information to the distributed network, eliminating the need for centralized stationary monitoring equipment.
2Area of stationary object
If stationary monitoring sites are deployed for all roadways, then coverage area is improved, but loss of substance (cost) increases
Solution Approach 1:
The patent makes mobile client devices perform multiple functions: they serve as GPS receivers, traffic sensors, communication transmitters, and navigation processors simultaneously. This multi-functionality allows a single device to replace what would traditionally require multiple specialized stationary monitoring equipment across the same geographic area.
Solution Approach 2:
Instead of deploying expensive stationary monitoring infrastructure across all roadways, the system uses distributed mobile devices that copy the monitoring function. These devices leverage existing hardware (GPS receivers, processors, communication modules) to provide widespread geographic coverage at minimal cost.
3Measurement precision
If real-time navigation data is provided for all locations, then measurement precision is improved, but use of energy (data transmission and processing) increases
Solution Approach 1:
The system implements partial action by having client devices transmit navigation information and traffic data selectively rather than continuously. The server receives samples from distributed clients and processes only the necessary data to generate accurate travel routes and traffic information, reducing overall energy consumption while maintaining real-time accuracy.
Solution Approach 2:
The patent segments the data collection and processing tasks between multiple distributed client devices and the central server. Each device independently collects local navigation information and transmits samples to the server, which then aggregates and processes this segmented data to provide comprehensive real-time navigation accuracy without requiring any single device to handle all processing energy demands.

AI summary
A method of operation of an intelligent real-time distributed traffic sampling and navigation system includes: receiving navigation information of a client; analyzing the navigation information to provide traffic information; generating a travel route based on the analyzing the navigation information; and sending the travel route for display on the client.
