Smart Crosswalk ground turthing GNSS app

Looking for developer to implement a mobile app on android and IOS to collect raw GPS data whenever a phone is within 100 meters of a smart intersection. Periodically, send data to a sever and post process it with RTKlib.

Android raw GNSS data code and client server code available for modification.

Will also need some real-time pedestrian safety alerts and transit rider features.

Here is the test site in Montgomery County Maryland. [login to view URL] These are the bus routes and the red markers are the 19 smart crosswalks in the County. THe COunty will help distribute the app. When ever a cell phone with the app travels through one of the 19 smart intersections, the app will record the GNSS raw data if available and regular GPS in GNSS raw data is not enabled on that phone. Periodically, the data is sent to our server. If it is raw data it will be post processes with libRTK software for precise posistion data. The raw GNSS data from the phone may need to be reformated for lib RTK post processing.

Also, would like to determine most likely mode of transportation from phone motion data from GPS speed/accerleration and or interial sensors.
