    Advanced Traffic Simulation

    A mixture of game and simulation for public transport.

    This project is about a game and a simulation to work together. The focus lies on public transport. Manage your line network in your home area. Upgrade your vehicles, build new roads, deal with accidents or plan replacement busses for railroad construction works. But it's also possible to drive the vehicle yourself or just walk around the world and enjoy your line network. By vehicle we mean: train, tram, subway, bus and monorail. By using an addon structure it is possible to customize the whole world or even include non-existing means of transport like the hyperloop. Plan, manage and drive all together in multiplayer. Either competing or cooperative.
