This paper studies the impact of route choice set of networks on the day-to-day traffic dynamics through conducting a group of experiments, in which four traffic networks with different sets for choice are used. It is observed that a deterministic user equilibrium (DUE) state is difficult to sustain and the probability of reaching DUE is larger in a network with smaller route choice set. Three day-to-day models are calibrated by using the experimental data. Results reveal that (1) there are linear relationships between traffic volume/flow changes obtained from the experiments and models; (2) when the same model is applied to different networks, the calibrated adjustment parameters are statistically different; and (3) the same model reveals different performances for different networks. Besides, it is shown the participants are more likely to change route choices in a network with larger route choice set and tend to switch away after experiencing a longer travel time.

本文通过一组实验研究了网络路由选择集对日常交通动态的影响，其中使用了四种不同选择集的交通网络。可以观察到，在路由选择集较小的网络中，确定性用户均衡（DUE）状态难以维持，达到 DUE 的概率较大。使用实验数据校准三个日常模型。结果表明：（1）实验和模型得到的交通量/流量变化之间存在线性关系；(2) 同一模型应用于不同网络时，标定的平差参数在统计上是不同的；(3) 同一个模型对于不同的网络表现出不同的表现。除了，
