Zhicheng’s research interests include education hot-zone identification. During a past study, Zhicheng and his colleagues used the Bayesian Poisson lognormal CAR model, which was developed to identify the relationship between the residents and the road network, land use, and socio-economic features. Following this, the Potential for Safety Improvements (PSI) for each unit was calculated and used for education hot-zone identification. Currently, Zhicheng is comparing the education hot-zone identification results with crash hot-zone identification results, using the same modelling methodology to confirm the significance of the application of statistical analysis in targeted safety education.
