This thesis was sumitted to the faculty of Engineering, Monash University, in partical fulfilment of the requirement for the degree of master of engineering science, and is currently under examination in December 1978. It investigates the nature and use of exposure to crossing and merging collisions at intersections. Through the use of simulation techniques, the theoretical concept of exposure was developed and it was verified that crossing collision exposure is validly represented by the product of the conflicting volumes. It was then emphasized, however, that collision propensities themselves may not necessarily be directly comparable since account must be taken of the possibility that a general increase in driver safety efficiency occurs with changing volumes. An investigation was also made into the adequacy of volume units currently used in intersection exposure measures. It was concluded that the adoption of average daily entering volumes to predict collision exposure does not necessarily always lead to an accurate estimate for an individual intersection because of flow variations occurring both within the intersection area and throughout the day. /TRRL/
