Thank you for your thorough analysis and for narrowing down the options
to a practical solution. Based on your findings, it’s clear that
dashcams and smartphones are the most viable tools for recording and
sharing live traffic data, especially given the restrictions on drones
and the lack of publicly available live satellite or aerial imagery.
Below, I’ll address your points and provide recommendations for
implementing your idea, including potential apps, tools, and approaches.
Key Insights from Your Analysis
    Satellite and Aerial Imagery:
        Live satellite imagery is not available for traffic monitoring.
        Aerial imagery from drones is restricted in cities due to No-Fly
Zones.
        Highway cameras are controlled by authorities and not accessible
to the public.
    Dashcams and Smartphones:
        Dashcams and smartphones can record live traffic and incidents
locally.
        Geolocated data can be uploaded to the cloud for public sharing.
    Navigation Apps:
        Apps like Magic Earth offer live traffic overlays but lack
real-time recording and sharing features.
        Running navigation and recording apps simultaneously on a single
device may be resource-intensive.
Proposed Solution
Your idea to use smartphones as dashcams for recording and sharing live
traffic data is practical and achievable. Here’s how it could work:
    Recording and Uploading:
        Use an Android app to record live traffic footage and upload
geolocated images/videos to the cloud.
        Allow drivers to manually select and tag specific scenes (e.g.,
accidents, congestion) for sharing.
    Cloud Sharing:
        Create a cloud-based platform where users can upload and view
shared traffic data.
        Use geolocation data to overlay incidents on a map for real-time
traffic updates.
    Integration with Navigation Apps:
        Run the recording app on one smartphone and a navigation app on
another device to avoid performance issues.
Recommended Tools and Apps
Here are some tools and approaches to help you implement your solution:
1. Android Apps for Dashcam Functionality
    DailyRoads Voyager:
        A popular dashcam app for Android that records video, takes
photos, and saves them to an SD card.
        Features include loop recording, G-sensor (auto-save on impact),
and GPS tagging.
        Limitation: Does not natively support cloud uploads, but you can
manually upload files.
    AutoGuard Dash Cam:
        Records video and automatically saves clips when it detects
collisions or sudden braking.
        Supports GPS tagging and cloud backups (via third-party services
like Google Drive).
        Limitation: Cloud uploads require a separate integration.
    Nextbase Dash Cam:
        A dedicated dashcam app that works with Nextbase devices but can
also be used on smartphones.
        Offers cloud uploads and real-time sharing features.
        Limitation: Primarily designed for Nextbase hardware.
2. Custom Android App Development
If existing apps don’t meet your needs, consider developing a custom app
with the following features:
    Live Recording: Record video and save it to the device’s SD card.
    Geolocation Tagging: Automatically tag recordings with GPS
coordinates.
    Cloud Upload: Allow users to manually select and upload clips to a
cloud platform.
    Map Integration: Overlay uploaded incidents on a map for real-time
traffic updates.
Tools for Development:
    Android Studio: The official IDE for Android app development.
    Google Maps API: For integrating maps and geolocation features.
    Firebase: For cloud storage, real-time database, and user
authentication.
3. Cloud Platform for Sharing
    Google Drive/Dropbox: Use existing cloud services for file storage
and sharing.
    Custom Cloud Solution: Build a dedicated platform using AWS, Google
Cloud, or Firebase to host and display shared traffic data.
4. Testing and Demo
    Open-Source Dashcam Apps:
        Explore open-source dashcam apps on GitHub (e.g., OpenCamera) to
test and modify code for your needs.
    Demo Apps:
        Look for demo apps that showcase GPS tagging and cloud uploads
to use as a starting point.
Implementation Steps
    Define Requirements:
        List the features you need (e.g., recording, GPS tagging, cloud
uploads, map integration).
        Decide whether to use an existing app or develop a custom
solution.
    Test Existing Apps:
        Download and test apps like DailyRoads Voyager or AutoGuard Dash
Cam to see if they meet your needs.
        Check if they support cloud uploads or can be integrated with
third-party services.
    Develop a Custom App (if needed):
        Use Android Studio to build an app with the required features.
        Integrate Google Maps API for geolocation and Firebase for cloud
storage.
    Create a Cloud Platform:
        Use Firebase or a similar service to build a platform where
users can upload and view traffic data.
        Overlay incidents on a map using geolocation data.
    Test and Refine:
        Test the app and platform with a small group of users.
        Gather feedback and refine the features based on user input.
Example Workflow
    A driver uses the app to record live traffic footage on their
smartphone.
    When they encounter an incident or heavy traffic, they manually
select and upload a clip to the cloud.
    The clip is tagged with GPS coordinates and displayed on a map for
other drivers to view.
    Other drivers can access the map to see real-time traffic updates
and plan their routes accordingly.
Conclusion
Your idea to use smartphones as dashcams for recording and sharing live
traffic data is both innovative and practical. While existing apps like
DailyRoads Voyager and AutoGuard Dash Cam offer some of the required
features, a custom solution may be needed to fully meet your goals. By
developing a dedicated app and cloud platform, you can create a powerful
tool for real-time traffic monitoring and sharing.
