Project Summary

This project aims to foster the use of LUTI (Land Use Transport Interaction) models for the design and evaluation of land use and transport policies by addressing these two impediments. This involves:

  • a) defining a calibration methodology and developing relevant and efficient algorithms to facilitate the parameter estimation of LUTI models;
  • b) defining a validation methodology, in both the historical and urban economics senses, and developing the related algorithms.

In both cases, analyzing the uncertainty that may arise from either the data or the underlying equations, quantifying how these uncertainties propagate in the model, and performing sensitivity analysis to determine the relevance of the various data and model parameters are of major importance. Completing these various tasks would make LUTI models easier to implement, and greatly enhance the confidence in their results.

Three LUTI models will serve as sample to test the methodologies that will be developed in the CITiES project: Tranus, UrbanSim, and Pirandello. They are quite representative of LUTI models, with two equilibrium models and one microsimulation model. Tranus and UrbanSim are Open Source and also the most largely applied models worldwide, while Pirandello is the only operating model developed in France. The study areas are the Grenoble region for Tranus, the Lyon region for UrbanSim and the Paris region for Pirandello, which offer different local contexts.
