    Modeling and Predicting Stochastic Merging Behaviors at Freeway On-Ramp Bottlenecks by Jian Sun, Kang Zuo, Shun Jiang, Zuduo Zheng

    Published 2018-01-01
    “…First, it gives the quantitative measurement of the rejected gap which is also a detailed description of non-merging event and investigated the characteristics of the multi-rejected gaps; second, taking the multi-rejected gaps into consideration, it further expanded the concept of the “critical gap” which can be a statistic one and the distribution function of merging probability with respect to such gaps was analyzed by means of survival analysis. This way could make the full use of multi-rejected gaps and accepted gaps and reduce the sample bias, thus estimating the critical gap accurately; finally, considering multi-rejected gaps, it created logistic regression models to predict merging behavior. …”
