Based on the analysis of drivers’ gap acceptance process of roundabout, the video was used to record drivers’ choice behavior when the vehicle entered roundabouts. Through the statistics and analysis of survey data, the results indicated that the gap acceptance behavior can be described by binary choice model—model. The calculation method of critical time headway was given which related with space headway and speed of the rear vehicle on major road. A conclusion was derived that the critical space headway would increase when the vehicles’ speed on the major road increased from the calculation results by use of SPSS software.
