uxsim.RouteChoice

class uxsim.RouteChoice(W)[source]

Class for computing shortest path for all vehicles.

Create route choice computation object.

Parameters:

W (object) – The world to which this belongs.

__init__(W)[source]

Create route choice computation object.

Parameters:

W (object) – The world to which this belongs.

Methods

__init__(W)

Create route choice computation object.

homogeneous_DUO_update()

Update link preference of all homogeneous travelers based on DUO principle.

route_search_all([infty, noise])

Compute the current shortest path based on instantaneous travel time.
homogeneous_DUO_update()[source]

Update link preference of all homogeneous travelers based on DUO principle. Vectorized by Claude 3.5 Sonnet.

route_search_all(infty=inf, noise=0)[source]

Compute the current shortest path based on instantaneous travel time.

Parameters:

  • infty (float) – value representing infinity.

  • noise (float) – very small noise to slightly randomize route choice. useful to eliminate strange results at an initial stage of simulation where many routes has identical travel time.
