An Analysis of Characteristics of Heavy Vehicle Behavior at Roundabouts in Japan

Heavy vehicles behave differently from ordinary passenger cars due to their characteristics such as larger size. Thus, it should be carefully considered when designing a road facility or evaluating its performance. This paper aims at analyzing the characteristics of heavy vehicle behavior at roundabouts under the Japanese situations. By using field data observed at a single-lane roundabout in Japan, an empirical analysis on headway parameters was conducted for examining the characteristics of heavy vehicles. It was confirmed that the headways which are formed by heavy vehicles are commonly greater than those formed by passenger cars only. The results in this paper are expected to be used for roundabout performance evaluations such as roundabout entry capacity estimation.
