Abstract The results of statistical analysis of the headway-speed variables in freely flowing freeway traffic are presented. The data base consists of trajectories constructed from aerial photographs of the Long Island Expressway. The conclusions are that headways, both space and time, are usually independent, and have an exponential distribution past the small values. Speeds are highly correlated, and have a normal distribution. Speeds and headways are independent except at the highest flow rates.
