Specialist Experience and Expertise

Traffic and transport modelling generally. More specifically: traffic assignment modelling (probit-based stochastic loading methods, SUE, elastic demand); matrix estimation (including bi-level problems, eg combination with assignment); traffic safety modelling (statistical analysis of road accident data: predictive accident modelling, regression-to-mean problem, effectiveness of remedial treatments)
