项目摘要

The traffic management on expressways is considered from the view of technical and economic aspects in the study. The traffic analysis model for the transfer system with integration of both ideas and it is applied to the real scale road networks. Additionally, the practical issues are also shown. The research results are summarized as follows :1) The precise idea of the transfer system to reduce traffic congestion is mentioned. Particularly, the effective way of transfer is discussed based on the present data of traffic survey. The possibility of introduction of the transfer system is discussed associating with ordinary traffic control. It is confirmed that the transfer system is defined as advanced traffic management technique with traffic information service.2) The traffic assignment technique with link interaction is introduced to analyze the traffic flow with the transfer system. The typical algorithm for traffic assignment (user equilibrium) can be used for solving the problem. Th … More erefore, the two different traffic flows on the same streets such as detour traffic and original traffic can be described and analyzed. This theoretical model can show the different traffic flows with different condition of the transfer system.3) The interaction between user behavior and traffic information is discussed to consider practical application of the transfer system. The real scale networks involving Hanshin expressway and related streets is analyzed to evaluate the impact of traffic flow change as an empirical example by using the stochastic traffic assignment. The social benefit of the transfer system in each individual location can be measured.4) The practical application of the transfer system is considered. The optimal locations of on and off ramps with the transfer system is formulated in terms of efficient use of the networks. As the problem is defined as a combinational optimization problem with traffic flow analysis, the genetic algorithm approach is introduced. The optimal location of the transfer system is shown from the calculation. Furthermore, the detour behavior model is produced with the empirical data to point out some problems of the practical transfer system.5) The research results are reported the several conferences and the further discussions are recommended. The some remarks are also planned to be reported the conferences related with traffic engineering. Less

本文从技术和经济两个方面对高速公路的交通管理进行了研究。将这两种思想相结合，建立了交通运输系统的交通分析模型，并将其应用于实际规模的路网。此外，还指出了实际问题。研究结果总结如下：1)提出了减少交通拥堵的换乘系统的精确思路。并结合现有的交通调查数据，探讨了有效的换乘方式。结合普通交通管制，讨论了引入换乘系统的可能性。确定了换乘系统是具有交通信息服务的先进交通管理技术。2)引入链路交互的交通分配技术，对具有换乘系统的交通流进行分析。典型的流量分配算法（用户均衡）可用于解决该问题。因此，可以对同一街道上的两种不同的交通流，如绕行交通和原始交通进行描述和分析。该理论模型能较好地反映交通系统在不同工况下的交通流。3)考虑到换乘系统的实际应用，讨论了用户行为与交通信息的交互作用。以包括阪神高速公路及其相关街道在内的真实规模网络为例，利用随机交通分配方法评价交通流变化的影响。在每个单独的地点，转移系统的社会效益是可以衡量的。4)考虑了传输系统的实际应用。在有效利用交通网络的前提下，制定了交通系统上下行匝道的最佳位置。将该问题定义为交通流分析的组合优化问题，引入了遗传算法方法。通过计算得出了输送系统的最优位置。在此基础上，利用实证数据建立了绕行行为模型，指出了实际运输系统中存在的问题。5)报告了研究成果，并提出了进一步讨论的建议。这些发言也计划在交通工程相关会议上发表。少
