Forecasting#

In this example, we present a full forecasting workflow for the Sioux Falls example model.

We start creating the skim matrices, running the assignment for the base-year, and then distributing these trips into the network. Later, we estimate a set of future demand vectors which are going to be the input of a future year assignnment with select link analysis.

# Imports
from uuid import uuid4
from os.path import join
from tempfile import gettempdir

import pandas as pd

from aequilibrae.utils.create_example import create_example
# We create the example project inside our temp folder
fldr = join(gettempdir(), uuid4().hex)

project = create_example(fldr)
logger = project.logger

Traffic assignment with skimming#

In this step, we’ll set the skims for the variable free_flow_time, and execute the traffic assignment for the base-year.

from aequilibrae.paths import TrafficAssignment, TrafficClass
# We build all graphs
project.network.build_graphs()
# We get warnings that several fields in the project are filled with NaNs.
# This is true, but we won't use those fields.

# We grab the graph for cars
graph = project.network.graphs["c"]

# Let's say we want to minimize the free_flow_time
graph.set_graph("free_flow_time")

# And will skim time and distance while we are at it
graph.set_skimming(["free_flow_time", "distance"])

# And we will allow paths to be computed going through other centroids/centroid connectors
# required for the Sioux Falls network, as all nodes are centroids
graph.set_blocked_centroid_flows(False)

Let’s get the demand matrix directly from the project record, and inspect what matrices we have in the project.

proj_matrices = project.matrices
proj_matrices.list()
name file_name cores procedure procedure_id timestamp description status
0 demand_omx demand.omx 1 None None 2020-11-24 08:47:18 Original data imported to OMX format
1 demand_mc demand_mc.omx 3 None None 2021-02-24 00:51:35 None
2 skims skims.omx 2 None None None Example skim
3 demand_aem demand.aem 1 None None 2020-11-24 08:46:42 Original data imported to AEM format


We get the demand matrix, and prepare it for computation

demand = proj_matrices.get_matrix("demand_omx")
demand.computational_view(["matrix"])

Let’s perform the traffic assignment

# Create the assignment class
assigclass = TrafficClass(name="car", graph=graph, matrix=demand)

assig = TrafficAssignment()

# We start by adding the list of traffic classes to be assigned
assig.add_class(assigclass)

# Then we set these parameters, which an only be configured after adding one class to the assignment
assig.set_vdf("BPR")  # This is not case-sensitive

# Then we set the volume delay function and its parameters
assig.set_vdf_parameters({"alpha": "b", "beta": "power"})

# The capacity and free flow travel times as they exist in the graph
assig.set_capacity_field("capacity")
assig.set_time_field("free_flow_time")

# And the algorithm we want to use to assign
assig.set_algorithm("bfw")

# Since we haven't checked the parameters file, let's make sure convergence criteria is good
assig.max_iter = 1000
assig.rgap_target = 0.001

# we then execute the assignment
assig.execute()

We can export our results to CSV or get a Pandas DataFrame, but let’s put it directly into the results database

assig.save_results("base_year_assignment")

And save the skims

assig.save_skims("base_year_assignment_skims", which_ones="all", format="omx")

Trip distribution#

First, let’s have a function to plot the Trip Length Frequency Distribution.

from math import log10, floor
import matplotlib.pyplot as plt
def plot_tlfd(demand, skim, name):
    plt.clf()
    b = floor(log10(skim.shape[0]) * 10)
    n, bins, patches = plt.hist(
        np.nan_to_num(skim.flatten(), 0),
        bins=b,
        weights=np.nan_to_num(demand.flatten()),
        density=False,
        facecolor="g",
        alpha=0.75,
    )

    plt.xlabel("Trip length")
    plt.ylabel("Probability")
    plt.title(f"Trip-length frequency distribution for {name}")
    return plt

Calibration#

We will calibrate synthetic gravity models using the skims for free_flow_time that we just generated

import numpy as np
from aequilibrae.distribution import GravityCalibration

We need the demand matrix and to prepare it for computation

demand = proj_matrices.get_matrix("demand_omx")
demand.computational_view(["matrix"])

We also need the skims we just saved into our project

imped = proj_matrices.get_matrix("base_year_assignment_skims_car")

# We can check which matrix cores were created for our skims to decide which one to use
imped.names
['distance_blended', 'distance_final', 'free_flow_time_blended', 'free_flow_time_final']

Where free_flow_time_final is actually the congested time for the last iteration

But before using the data, let’s get some impedance for the intrazonals. Let’s assume it is 75% of the closest zone.

imped_core = "free_flow_time_final"
imped.computational_view([imped_core])

# If we run the code below more than once, we will be overwriting the diagonal values with non-sensical data
# so let's zero it first
np.fill_diagonal(imped.matrix_view, 0)

# We compute it with a little bit of NumPy magic
intrazonals = np.amin(imped.matrix_view, where=imped.matrix_view > 0, initial=imped.matrix_view.max(), axis=1)
intrazonals *= 0.75

# Then we fill in the impedance matrix
np.fill_diagonal(imped.matrix_view, intrazonals)

Since we are working with an OMX file, we cannot overwrite a matrix on disk. So let’s give it a new name to save.

imped.save(names=["final_time_with_intrazonals"])

This also updates these new matrices as those being used for computation

imped.view_names
['final_time_with_intrazonals']

Let’s calibrate our Gravity Model

for function in ["power", "expo"]:
    gc = GravityCalibration(matrix=demand, impedance=imped, function=function, nan_as_zero=True)
    gc.calibrate()
    model = gc.model
    # We save the model
    model.save(join(fldr, f"{function}_model.mod"))

    _ = plot_tlfd(gc.result_matrix.matrix_view, imped.matrix_view, f"{function} model")

    # We can save the result of applying the model as well
    # We can also save the calibration report
    with open(join(fldr, f"{function}_convergence.log"), "w") as otp:
        for r in gc.report:
            otp.write(r + "\n")
Trip-length frequency distribution for expo model

And let’s plot a trip length frequency distribution for the demand itself

plt = plot_tlfd(demand.matrix_view, imped.matrix_view, "demand")
plt.show()
Trip-length frequency distribution for demand

Forecast#

We create a set of ‘future’ vectors using some random growth factors. We apply the model for inverse power, as the trip frequency length distribution (TFLD) seems to be a better fit for the actual one.

from aequilibrae.distribution import Ipf, GravityApplication, SyntheticGravityModel

Compute future vectors#

First thing to do is to compute the future vectors from our matrix.

origins = np.sum(demand.matrix_view, axis=1)
destinations = np.sum(demand.matrix_view, axis=0)

# Then grow them with some random growth between 0 and 10%, and balance them
orig = origins * (1 + np.random.rand(origins.shape[0]) / 10)
dest = destinations * (1 + np.random.rand(origins.shape[0]) / 10)
dest *= orig.sum() / dest.sum()

vectors = pd.DataFrame({"origins":orig, "destinations":dest}, index=demand.index[:])

IPF for the future vectors#

Let’s balance the future vectors. The output of this step is going to be used later in the traffic assignment for future year.

args = {
    "matrix": demand,
    "vectors": vectors,
    "column_field": "destinations",
    "row_field": "origins",
    "nan_as_zero": True,
}

ipf = Ipf(**args)
ipf.fit()

When saving our vector into the project, we’ll get an output that it was recored

ipf.save_to_project(name="demand_ipfd_omx", file_name="demand_ipfd.omx")
<aequilibrae.project.data.matrix_record.MatrixRecord object at 0x7f90c88d76a0>

Impedance#

Let’s get the base-year assignment skim for car we created before and prepare it for computation

imped = proj_matrices.get_matrix("base_year_assignment_skims_car")
imped.computational_view(["final_time_with_intrazonals"])

If we wanted the main diagonal to not be considered…

# np.fill_diagonal(imped.matrix_view, np.nan)

Now we apply the Synthetic Gravity model

for function in ["power", "expo"]:
    model = SyntheticGravityModel()
    model.load(join(fldr, f"{function}_model.mod"))

    args = {
        "impedance": imped,
        "vectors": vectors,
        "row_field": "origins",
        "model": model,
        "column_field": "destinations",
        "nan_as_zero": True,
    }

    gravity = GravityApplication(**args)
    gravity.apply()

    # We get the output matrix and save it to OMX too,
    gravity.save_to_project(name=f"demand_{function}_modeled", file_name=f"demand_{function}_modeled.omx")

We update the matrices table/records and verify that the new matrices are indeed there
