When solving nonlinear least-squares problems, it is often useful to regularize the problem using a quadratic term, a practice which is especially common in applications arising in inverse calculations. A solution method derived from a trust-region Gauss-Newton algorithm is analyzed for such...

Transport systems economical impacts justify great efforts to collect and analyse data on mobility. Recently, Belgium ran, at last, nation wide and regional travel surveys. Descriptive analyses of survey data are very useful but limited as a comprehensive tool to explain travel demand and its...
