Urban Road Speed Calculation Using User Track Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost of deploying hardware devices to monitor urban road conditions limits the reliability of traffic monitoring, as it is not feasible to deploy them on a large scale, resulting in incomplete reflection of urban road running conditions.
Innovation Solution
A method that calculates the running speed of urban roads using user track data and road network data, without the need for hardware devices, by obtaining a weighed road length and actual passing period, and providing this information on digital maps, utilizing existing data sources like GPS and road condition data from services like Baidu Maps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If hardware devices such as video monitor devices are deployed at specified positions of urban roads to obtain running speed, then the accuracy of running speed measurement is improved, but the cost increases and large-scale deployment is limited
Solution Approach 1:
The patent uses GPS tracking data from mobile devices as a virtual copy of traditional video monitoring systems. Instead of deploying physical hardware devices, the system collects positioning information from users' mobile devices to calculate running speeds, achieving the same measurement function without the associated hardware costs and deployment complexity
Solution Approach 2:
The patent replaces the mechanical/video-based monitoring system with an electronic/GPS-based system. By substituting physical video monitor devices with electronic positioning data collection and processing, the system eliminates hardware deployment requirements while maintaining measurement capability
2Reliability
If hardware devices are deployed on a large scale to reflect comprehensive urban road conditions, then the reliability of monitoring is improved, but the cost becomes prohibitively high
Solution Approach 1:
The patent leverages the universal use of GPS functionality in modern mobile devices. Since almost all smartphones and navigation devices already contain GPS capabilities, the system can universally collect data from any user's device without requiring additional specialized hardware, thereby achieving large-scale deployment at minimal cost
Solution Approach 2:
The system utilizes the existing GPS functionality that users already have in their devices. Users' mobile devices serve themselves by providing positioning data that contributes to the collective traffic monitoring system, eliminating the need for external hardware deployment while achieving comprehensive coverage
3Measurement precision
If traditional video monitor devices are used to obtain running speed, then the measurement function is achieved, but the system complexity and deployment difficulty increase
Solution Approach 1:
The patent creates a virtual monitoring system using GPS data copies from mobile devices instead of physical video monitoring infrastructure. This copying approach replaces complex hardware deployment with simple data collection and processing, dramatically improving ease of operation
Solution Approach 2:
The patent substitutes the mechanical video monitoring system with an electronic data processing system. By replacing physical devices with software-based GPS data analysis, the system eliminates deployment complexity while maintaining measurement precision
