The local public transport service in The Hague, HTM, has been using displays which worked with a closed and outdated system. As our final project on secondary school we created a prototype to replace the old system by using a Raspberry Pi microcontroller in combination with open data from openov.nl. We have attached a USB-to-RS232 converter and a 3G receiver to the Rasberry Pi.
In April 2013 we participated with our project to the International Conference of Young Scientists in Indonesia and won a bronze medal and the special award from blibli.com in the category of Computer Science!
