This is the repository for my Msc Computing Dissertation.

There are two parts to this project.

• Data processing to produce a set of alert points
• Mobile application to give audible alerts while driving

There are two scripts required for to run the data processing. Before running any scripts the following is required

• The .osm or .osm.pbf file will need to be put inside the data-processing/osm-raw directory.
• Both Osmconvert and Osmfilter need to be downloaded and placed in the data-processing directory with the file names osmconvert64.exe and osmfilter.exe respectively.

Once the above is completed the two scripts are called for the data processing.

• First the raw data needs initial filtering by running .\filter-raw-osm-data.ps1 .\osm-raw\NAME_OF_OSM_FILE.osm.pbf. Once completed this will create a NAME_OF_OSM_FILE.osm file in the osm-filtered directory.
• Second run the python script with the following command python .\process_data.py .\osm-filtered\NAME_OF_OSM_FILE.osm When completed the alerts will be saved to a JSON file NAME_OF_OSM_FILE.json in the alerts directory.

The alert JSON file is copied into the app/app/src/main/res/raw directory. Then in AlertCheckerService.java within app/app/src/main/java/com/example/gpssafetydrivingapp/alerts within the loadAlertPoints() method the line getApplicationContext().getResources().openRawResource(R.raw.NAME_OF_JSON) will need NAME_OF_JSON to be replaced with JSON filename without the extension.

The Android application can then be built.
