A model describing the kinematics of vehicle trajectories during the passing (overtaking) manoeuvre on two-lane, two-way rural roads and highways was developed. This model was then used to determine the total required sight distance in terms of exogenous model parameters. Using this model a risk assessment analysis was conducted using Monte Carlo computer simulation software and the results examined. These results provide insight into those parameters that influence the required sight distances more strongly than others. It is shown that the acceleration characteristics of the passer vehicle may not have a significant affect on required passing sight distance and that further research into the actual behaviour of drivers performing the passing manoeuvre may be required to develop appropriate required passing sight distance standards (Author/publisher) For the covering entry of this conference, please see ITRD abstract no.
