Exploring new methodologies and perspectives on the road safety impacts of bus priority

This thesis aims to develop an in-depth understanding of the road safety implications of implementing bus priority through an investigation of accident records and conflicts in Metropolitan Melbourne. It is structured around six approaches that had been established to fill the knowledge in the area of bus priority safety effects. The first approach concerns an exploration of the safety effects of bus priority at the aggregate level. The third approach relates to an investigation of bus accidents at the route level. Using two mainstream modelling methodologies (MENB - Mixed Effects Negative Binomial and BPNN – Back Propagation Neural Network modelling), risks factors in bus accidents were explored with particular attention paid to the safety effect of bus priority. The fourth approach concerns the analysis of bus accidents in terms of vehicle, driver, roadway and environmental factors. The fifth approach centres on an investigation of the bus priority effect (bus lanes) at a corridor-level through micro-simulation. The sixth approach concerns an estimation of crash risk for vehicles that are behind a slowing or stationary bus at a bus stop in a mixed traffic configuration. Overall the thesis presents a range of advances in knowledge in the area of bus priority. Through the six approaches, new light has been shed on the safety effects of bus priority. The thesis concludes with a synthesis of the findings, in which its implications in the context of bus priority research and planning as well as opportunities for future research are presented.
