Hello, I'm here to put a pretty much theoretical question about the vehicular model SUMO is actually using (by what is written on the documentation site). Simply put, correct me if I'm wrong, you have these 2 simple update rules: v1 = min( v(t) + b , vmax , vsafe) v0 = v1 - epsilon ( v1 - ( v(t) - b)) where epsilon = 0.4 (in the referred paper).
Now, v(t+1) is supposed to be a random number between v0 and v1 and here is the question: I've got two stopped car so close that vSafe is 0, which means that v1 equals 0. If b is not equal to 0 (which is, by the way, the maximum breaking power), v0 will be a number !=0 hence you'll see a car moving back and trying to put himself in a correct position until v(t) equals b. Is it working as intended? Am I getting something wrong? Sorry to bother you with these questions, tell me if this shouldn't be the place to ask for these sort of questions.
