Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for monitoring and managing traffic pollution in vehicles lack real-time data dissemination to users and do not effectively utilize existing air quality sensors to generate comprehensive pollution maps, which are essential for minimizing exposure, especially for sensitive populations, and for urban planning.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If existing automotive air quality sensors are integrated with client devices and remote servers to collect and transmit real-time pollution data, then real-time pollution information and comprehensive pollution maps can be provided to users, but system complexity and data management requirements increase
Solution Approach 1:
The system divides the pollution monitoring function into separate modular components: automotive air quality sensors in vehicles, client devices for data collection and processing, and remote servers for storage and map generation. Each component operates independently but communicates through standardized interfaces, reducing overall system complexity while enabling real-time pollution information dissemination.
Solution Approach 2:
The system uses existing automotive air quality sensors that were originally designed for cabin air quality control, giving them a dual function: maintaining vehicle air quality and contributing to comprehensive traffic pollution mapping. This multi-functionality leverages existing infrastructure without requiring entirely new sensor systems.
2Measurement precision
If pollution detectors are installed in a large number of vehicles to generate comprehensive pollution maps, then coverage and accuracy of pollution data improve, but cost and deployment complexity increase
Solution Approach 1:
The system leverages existing automotive air quality sensors that are already installed in vehicles for cabin air quality management. These sensors automatically perform pollution detection without requiring additional dedicated monitoring equipment, enabling comprehensive pollution mapping through vehicles' existing infrastructure rather than requiring new sensor deployment.
Solution Approach 2:
The system combines data from multiple existing automotive air quality sensors across numerous vehicles to create comprehensive pollution maps. By merging data from these distributed sensors, the system achieves high spatial and temporal resolution pollution coverage without the cost and complexity of deploying a centralized monitoring network.
3Productivity
If real-time pollution data is transmitted from multiple vehicles to remote servers, then up-to-date pollution maps can be generated, but data transmission bandwidth and processing requirements increase
Solution Approach 1:
Client devices perform preliminary processing of pollution data locally, filtering and organizing sensor readings before transmission to remote servers. This pre-processing reduces the volume of data that needs to be transmitted over the network, decreasing bandwidth requirements and energy consumption while still enabling timely generation of updated pollution maps.

Data Source
AI summary
A traffic pollution mapper detects pollution variations and generates mapping information for establishing one or more pollution maps. The traffic pollution mapper includes one or more pollution detectors, installed on vehicles, that detect pollution and generate pollution information from the same as the vehicles travel through traffic. This pollution information may be combined with location information and a timestamp to create mapping information that is stored on a server. The mapping information may be queried by one or more client devices in various formats, including as a pollution map. The traffic pollution mapper may utilize various sensors to detect pollution, including automotive AQSs that provide binary open and close signals.
