Effectiveness of Latent Class Multinominal Logit Model Considering Latent Class with Homogeneousness
Byung‐Joo Lee, Moon NamGung · Journal of the Korean Society of Civil Engineers · 2003
Therefore, we confirm the effectiveness of LCML model that can consider latent class with homogeneousness as comparing with MNL model, the latent class exist in the road users, and what factors were considered in route choice behavior by latent class in this study. Traditional MNL model supposes that the road users are only one class, but latent classes with homogeneousness in the road users exist in reality. This fact is very important problem to understand the decision-making process of the road users. As the result of modeling, it is increase the likelihood ratio of LCML model than MNL model. So, we found that latent class exists in the road users and latent class considered the different factors in route choice behavior. Especially, LCML model can improve the effectiveness for traffic information because can find main target class and effective factors among latent classes. According to the result above, when offer the traffic information, we found that it is important to construct effective traffic information system as setting the main target class for information and offering a verity information.
