Abstract :
The aim of this paper is to analyze the influence of speed dispersion on traffic safety. The average speed difference (ASD for short) of two neighboring vehicles was used to define the speed dispersion. Based on the traffic data obtained from airport freeway in China and A20 freeway in the Netherlands, we carried out a comparative study on speed dispersion characteristics. We found that the speed dispersion of traffic flow on Airport freeway were larger than that on A20 freeway. The comparing results showed that A20 freeway was safer than Airport freeway. Some possible reasons were provided in this paper. This indicates that the ratio of large vehicle, traffic flow and over speed are the three main factors of speed dispersion influence on traffic safety.
