Co-Aps will develop a library that can be intregated with any travel companion, or operator like in the case of MetroTenerife. My-TRAC application and technology will be used for the demostration of the Co-Aps features

Co-Aps is a mobile application that helps reduce the spread of COVID-19 by managing density in public transport and public spaces.

Even though scientific evidence so far seems to indicate that there have been very few contagions on public transport systems, it is important that our sector continues its efforts to provide the safest possible environment for travellers.

The Co-Aps platform implements mobile technology to gather anonymous user data, open data from cities and data from third party services to provide relevant information about crowds and density to public transport operators and city authorities. This is done to inform and thus better protect citizens against the global pandemic by enabling them to avoiding crowds.

You can join Co-Aps!

We need users like yourself to provide us with valuable data on density in public transport. Now, how will this data be collected?

This will happen through users taking part in Co-Aps challenges. When using the app, you can participate in challenges across your city. And with every new challenge played, you will be awarded points that can later be exchanged for various prizes. Read more below!

Available for both iOS and Android, Co-Aps offers many different registering options
