Dr. Hassan Bin Tahir

Research Fellow

Brief Detail: Hassan is a Research Fellow in transportation engineering at the Queensland University of Technology (QUT). His expertise lies in traffic safety, highway geometric design, pavement materials, and the application of statistical and econometric methods to examine complex transport problems. He was a PhD student at QUT before joining as a research fellow. He holds five years of experience in highway geometric design as a senior engineer at NESPAK, Pakistan. He is also a reviewer of the Transportation Research Board conference.

 

PhD Title: Before-After Safety Evaluation of Engineering Treatments Applying Econometric Models for Unobserved Heterogeneity

Brief Detail: Hassan’s PhD research aimed to develop comprehensive analytical frameworks for the before-after evaluation of engineering treatments utilising heterogeneous econometric models. In particular, his research endeavoured to achieve four objectives. First, to investigate the effect of different segmentation approaches on the safety effectiveness of engineering treatments. Incorporating the learning from the first objective, his second objective was to propose a framework that accommodates unobserved heterogeneity in the Empirical Bayes approach. Third, he examined the performance of various engineering treatment evaluation techniques using a hypothetical treatment setup. Fourth, he proposed a novel mixed distribution multivariate model that simultaneously estimates multiple crash types while accounting for the correlation in multiple crash types by severity, the unobserved heterogeneity, and preponderance of zeros in evaluating the safety of the whole highway system.
