This document proposes a new traffic reporting app that would enhance an existing phone tracking system. It would have users send their GPS location every 60 seconds to a central server, which would identify traffic conditions and mark congested streets in red on Google Maps. The app would initially launch in Munich, Zaragoza, and Zebugg, targeting students and teachers, but hopes to expand to other cities. It estimates startup costs of €1000-4000 and calculates a break-even point of 100 users paying €10 each. Key strengths are building on an existing system and addressing an unmet need, while weaknesses include the challenges of realizing and funding the project. Local competitors like Google Maps' traffic feature are less detailed.
