Single-vehicle data of highway traffic - a statistical analysis

摘要

In the present paper single-vehicle data of highway traffic are analyzed ingreat detail. By using the single-vehicle data directly empirical time-headwaydistributions and speed-distance relations can be established. Both quantitiesyield relevant information about the microscopic states. Several fundamentaldiagrams are also presented, which are based on time-averaged quantities andcompared with earlier empirical investigations. In the remaining parttime-series analyses of the averaged as well as the single-vehicle data arecarried out. The results will be used in order to propose objective criteriafor an identification of the different traffic states, e.g. synchronizedtraffic.
