Crate sim

source ·
Expand description

The sim crate runs a traffic simulation on top of the map_model. See also

The simulation is very roughly layered into two pieces: the low-level “mechanics” of simulating individual agents over time, and higher-level systems like TripManager and TransitSimState that glue together individual goals executed by the agents.

Helpful terminology:

  • sov = single occupancy vehicle, a car with just a driver and no passengers. (Car passengers are not currently modelled)

    An experimental SEIR model by glued to the traffic simulation. Transmission may occur when people spend time in shared spaces like buildings, bus stops, and buses.
  • recorder 🔒
  • render 🔒
    Intermediate structures so that sim and game crates don’t have a cyclic dependency.
  • router 🔒
    For vehicles only, not pedestrians. Follows a Path from map_model, but can opportunistically lane-change to avoid a slow lane, can can handle re-planning to look for available parking.
