Abstract:

This paper outlines the development of a simulation modelling approach to assess the safety performance of roads. Statistical analysis, numerical modelling using Newtonian Mechanics, and micro simulation models have been used by researchers to assess roads safety performance. In this research a combination of these three methods is utilized to improve the assessment of safety at road locations compared to previous works. Micro simulation forms the basis of the framework while statistical models and numerical models using Newtonian Mechanics are the other models utilized and imbedded into the micro simulation model. The input into the micro simulation model is general traffic conditions and its output is a measure of safety performance of roads. The framework consists of two main parts. The first is the estimation of the number and severity of conflicts from general traffic flow inputs. The second part is an estimation of the expected injury severity of individuals, involving in the conflict, should the simulated conflict lead to a crash. The Australian Crash In-Depth Study (ANCIS) data base is used to estimate the statistical and numerical model parameters. The modelling framework is applied to an intersection in Melbourne, Australia and its associated safety performance results are interpreted.
