Pull request information

  • Status: ready to merge
  • Kind of changes: new features
  • Related PR or issue: None

Description

  • added an ignore_noise option to the controllers to deactivate noise near the start of networks
  • moved the "vehsPerHour" version of the inflows from sumo's interface to the VehicleParams class. This gives us more control on how vehicles enter the network.
  • modified the edgestarts to the highway network. This is needed when calling the ignore_noise feature.

Have you checked the performance of manually adding each vehicle vs specifiying an inflow? Seems like it could cause significantly more traci calls?

Otherwise, seems fine. I think this will be really useful.

accel += np.random.normal(0, self.accel_noise)
if self.ignore_noise is None:
# Add noise to the vehicle for all positions in this case.
accel += np.random.normal(0, self.accel_noise)

realized that this should probably be seeded with SUMO seed as well.

how does this work if adding a vehicle at the beginning of the lane with the given depart_speed is unsafe? Does it have the same behavior as SUMO inflows (either wait, adapt, or throw away the existing vehicle)?

same as above, we should sync the seeds to get reproducibility

name = names[i + 1]

# Choose the departure speed.
depart_speed = self._inflows[name]["departSpeed"]

should this also be adaptive?

at each time step, we should shuffle the vehicles to be added so they're not added in batches (i.e. 5 humans, then 2 avs)
