| 摘 要： | 针对出行行为的出行模式,出发时间/路径选择三个方面,建立了基于路段的理想动态用户最优的变分不等式模型,该模型将用户的出行方案制定和实施作为一个整体进行考虑,表明了在满足动态用户最优选择条件下,交通流在出行模式、出发时间和出行路径上取得一致的动态均衡性,通过必要性和充分性的论证,得到了变分不等式模型和动态用户最优出行模式/出发时间/路径选择均衡条件的等价性,对模型解的存在惟一性成立需要满足的条件作了讨论,提出了求解的嵌套对角化算法,在此基础上,使用一个简单算例对模型进行了验证. |

| Abstract: | This paper proposes a link-based variational inequality formulation for the ideal DUO travel mode/departure time/route choice problem.This formulation consider travelers' scheme establishing and it's implementing as a whole.It demonstrates that traffic flow can reach dynamic equilibrium simultaneously on travel mode/departure time/route under the assumption that DUO choice conditions is satisfied.This paper establishs the equivalence of the VI formulation and the DUO choice conditions by demonstrating the n... |
