Capturing correlation with a mixed recursive logit model for activity-travel scheduling
Transportation Research Part C, 93:73-291, 2018
    Highlights:
  • Combining recursive logit with mixed logit framework for activity-based modeling.

On the similarities between random regret minimization and mother logit: the case of recursive route choice models
Journal of Choice Modeling, 23C:21-33, 2017
    Highlights:
  • Link-based route choice models (no path choice set generation).
  • We formulate random regret-based recursive logit models.
  • Two new specifications of the random regret functions.
  • New mother logit models that are equivalent to the regret-based models.
  • Estimation and cross-validation results using real data.

A dynamic programming approach for quickly estimating large network-based MEV models
Transportation Research Part B 98(1):179-197, 2017
    Highlights:
  • A new approach for quickly estimating MEV models with large choice sets.
  • MEV models are formulated as dynamic discrete choice models.
  • The dynamic models generalize the network MEV and are consistent with MEV theory.
  • Estimation using the concept of network flows and the nested fixed point algorithm.
  • Numerical results based on simulated and real data.

    Highlights:
  • Model estimated and validated using bike GPS data on network of 40,000 links.
  • Quick computation of link flows without choice set generation.

A misspecification test for logit-based route choice models
Economics of Transportation 4(4):215-226, 2015.
    Highlights:
  • We show how White's information matrix test can be applied to route choice models.
  • Results for path-based and link-based (recursive logit) models.
  • Comparison of information matrix and IIA and McFadden–Train Lagrange multiplier tests.
  • Monte Carlo experiment results assess the size and power of the tests.
  • Path-based and link-based models are strongly rejected when applied to real data.

A nested recursive logit model for route choice analysis
Transportation Research Part B 75(1):100-112, 2015
    Highlights:
  • The IIA property is relaxed and random terms are correlated.
  • Link-based model: no choice sets of paths are required.
  • Efficient estimation and prediction.
  • Estimation and cross-validation results using real data.

 

Mogens Fosgerau, Emma Frejinger, Anders Karlstrom
A link based network route choice model with unrestricted choice set
Transportation Research Part B 56(1):70-80, 2013
    Highlights:
  • A model for the choice of route in a network.
  • Link size attribute: a deterministic correction for correlation.
  • No choice set generation needed.
  • A dynamic specification of sequential link choices is equivalent to a static logit model.
