Apps

trag.me™ is a name used to describe all the apps developed by Hermes Traffic Intelligence. Most of these apps are not intended for the common market, and for that reason they will only be found on this website. Below you will find descriptions of the apps currently in use or under development.

trag.me - Tracker

trag.me - Tracker is an Android based app designed to keep track of the whereabouts of a number of participating users / test subjects. Each subject will have an Android based smartphone with the app running at all times during transport. Whenever the transportation mode (walking, driving in a car, riding the bus, …) changes the subject should mark this using the app. The position of the smartphone and the corresponding transportation mode are transmitted to the trag.me website. The functionality of having the smartphone estimate the transportation mode itself is being tested using another app.

(Near) real-time transmission from the smartphone will be at the phone owner's expense. The amount of data is not vast so it should come at a relatively small cost. The user can configure the app to only transmit measurements when this can be done via a (possibly free of charge) WiFi connection. All measurements will be timestamped by the phone when measured so the delayed transmission will not result in wrong data, only data will not be real-time.

The app needs accelerometers for determining the transportation mode of the smartphone. If GPS is available, and accelerometers are not, the smartphone reports positions and user selected transportation mode only.

As the trial manager you will be given web access to follow each subject in near real-time, including the current transportation mode reported by the subject. This will allow trials to be set-up to monitor e.g. the use of public and private transportation within a selected population. During and after the trial the trial manager will have full access to all measured positions with corresponding transportation modes for all participating subjects.

trag.me - Travel Mode

App for automatically detecting travel mode. Although this is also included in newer versions of Android and iOS, it is believed that the functionality of this app is way better than what is seen in other places. It relies on data from trag.me - Tracker to be updated.

trag.me - Route

An app for finding the best route, taking current traffic conditions, road work, and other data available into considerations.

trag.me - Speedometer

Simple app that shows speedometer. While running the app will send speed, position, and accelerometer data to a trag.me server.
