摘要:
为了研究高速公路入口匝道上车辆的汇入规律,利用摄像机和Autoscope-2004图像处理系统在江苏、山西、河北、北京、天津、广东等地对高速公路合流区加速车道上车辆的汇入特征数据进行了大量调查.在对调查数据进行处理分析的基础上,运用概率分析和微分法建立了匝道车辆的汇入概率模型和行驶距离分布概率模型,利用实际数据对模型进行检验,并举例说明模型在高速公路加速车道长度的设计、评价和分析方面的应用.该模型揭示了匝道车辆汇入概率与合流区几何特征、交通特征的数学关系,不但解释了调查结果,而且对高速公路规划设计、控制管理等工程实践有重要的指导意义.
Abstract:
In order to work out the merging regularity of the on-ramp freeway junction, video tape recorder and Autoscope-2004 image sensing system are used to investigate merging characteristics on freeway interchanges in many provinces and cities such as Jiangsu, Shanxi, Hebei, Beijing, Tianjin and Guangdong. Based on the analysis and disposal for investigating data, the probability of merging model and the probability of travel distance on acceleration lane without merging model are set up with probability analysis and differential method. It is found that this model is coincident with actual data, and their appliance for designing, estimating, and analyzing the length of highway acceleration lane is illustrated. This model reveals the mathematical relationship between geometric features and traffic characteristics of freeway merge area. The model explains the inquisition results and it is significant for guiding engineering practice in planning, designing and management of freeway.
