InconTRAMi is a route planner for Milan’s public transports network ATM, differently from “usual” route planners it will try to find the best meeting points for two persons. By inputing your starting points, it will show the more easily reachable places for both persons. By moving the mouse over the map it will show which lines will permit you to reach that place.
Short usage policy: it is very experimental, I decline every responsibility coming from the use or misuse of it. It considers just ATM’s network; it doesn’t consider line hopping; the data it’s using may be not up to date. It uses data kindly made available by Comune di Milano. See the application page for the full policy (in italian).
The source code is available on GitHub.
p.s. “route planner for meeting points” is a horrible name, I’m taking suggestions.
