Thesis abstract:

«p style="text-align:justify"»«span style="color:#222222"»This project aims to determine where and when Random Breath Testing (RBT) and Random Drug Testing (RDT) programs should occur to achieve a more significant impact on road safety in Australia. This will be achieved in the below phases: Phase 1 of the project comprises a comprehensive and systematic literature review to outline the principles of effective DUI countermeasures. In Phase 2, a hybrid aggregated macroscopic and microscopic traffic model of offenders captures in RBT and RDT programs in different states of Australia will be constructed to find how RDT and RBT programs change offenders’ travel behaviour such as primary mode, origin to destination, time, and frequency of travel. Phase 3 of the project is the development of optimization models for RBT and RDT programs. These two law enforcement programs utilize equipment and workforce to capture violators, with the aim to reduce DUI and thus, improve traffic safety and reduce road trauma. Phase 4 is to review the previous steps and to prepare documents, reports, software, and traffic model. The proposed framework can be easily adapted for and transferred across different jurisdictions in Australia.«/span» «span style="color:#222222"»By addressing these key objectives, the study aims to contribute to the development of evidence-based policies and practices that can lead to improved road safety outcomes in Australia.«/span»«/p»
