摘要:
为了获得混合交通流条件下无控制交叉口的通行能力,采用冲突技术法进行分析.通过对典型无控制交叉口的实际调查和观测,基于冲突理论,综合考虑各向交通流的相互影响,分别建立了各向机动车流、行人流和非机动车流的通行能力计算模型.在模型中引入冲突系数反映各向交通流之间的优先关系,利用修正冲突系数反映交通流的实际观测优先级和优先程度,并对模型中的行人流和非机动车流进行了组团计算,进一步对无控制交叉口共用车道和拓宽路口的通行能力进行了计算.最后根据实际观测给出模型参数标定基本值,并对模型参数进行了修正.
Abstract:
In order to determine the capacity of all-way stop-controlled(AWSC)intersections, conflict technique method is utilized to analyze traffic conflicts between traffic streams. Based on conflict technique and field data, an improved procedure or model was derived to determine the capacity of vehicular traffic streams and non-motorized traffic streams at AWSC intersections. Conflict coefficients were introduced into the model to reflect the priority relationships between traffic streams and were modified to show the cases of so-called limited priority. Pedestrian traffic streams and bicycle traffic streams were taken into account in terms of groups within the capacity model. Furthermore, the procedure was developed to obtain the capacity of shared lanes and flared entries at AWSC intersections. In addition, according to the field investigations and observations at several typical AWSC intersections, the model parameters were calibrated and modified for conditions in China. In conclusion, the methodology provides a quite valuable reference for determining the capacity of traffic streams at AWSC intersections.
