This paper describes quantitative evaluation of driving assistance systems that use on-board sensors for getting surrounding vehicle information, and/or inter-vehicle communications for sharing information with other vehicles. The safety performance of each system is quantitatively evaluated with an improved microscopic traffic flow simulator. Simulation results show that the performance of the system using both on-board sensors and inter-vehicle communications is higher than that of the system using on-board sensors only or inter-vehicle communications only. In addition, they show that the performance of the system using only communications exceeds that of the system using only sensors when the penetration ratio is greater than 96%.
