지방부 2차로도로의 차두시간 분포 모델에 관한 연구 = A Study on Headway Distribution Models of Rural Two Lane Roads

다국어 초록 (Multilingual Abstract)

PURPOSES: This study was done to model the headway distribution of rural two lane roads.
METHODS: Time headway data for the various level of traffic volumes was measured in twelve sites. Based on the time headway data,existing seven mathematical models were evaluated and selected by comparing graphically the measured and theoretical distributions andconducting the Chi-square test.
RESULTS: The results show that both the Schul model and Composite Model were the most appropriate models of the models. Based on themeasured time-headway distributions, this study proposed a new headway distribution model by the shift of the Schul model.
CONCLUSIONS : The shifted Schul model has the ability to describe time headway distirbutons for random, intermediate, and constantheadway states.
