Hello I wanted to simulate a busy urban road,similar to Darpa Urban Challenge for an autonomous self-driving-car. I'm in search of simulators for that.
I've seen gazebo since its integration with ROS is easier but editing world files or indeed creating them itself is difficult. In torcs simulator I have seen many world files but not many sensors. I don't want much physics in my simulation. I want a light weight simulator(for checking out path planning on an urban road) and in which creating roads are easier.
I've even searched for gazebo sdf files similar to urban city but in vain.
