Abstract We analyzed time-series changes in people’s purpose-specific mobility characteristics owing to the COVID-19 pandemic in the Tokyo area of Japan, where only legally non-binding requests for self-restraint were enforced. A multiple regressio

Unsupervised outlier detection without the need for clean data has attracted great attention because it is suitable for real-world problems as a result of its low data collection costs. Reconstruction-based methods are popular approaches for unsuperv

Unsupervised outlier detection is commonly performed using reconstruction-based methods such as Principal Component Analysis. A recent problem in this field is the learning of low-dimensional nonlinear manifolds under L0-norm constraints for error te

Cooperation among different vehicles is a promising concept for Mobility as a Service (MaaS). A principal problem in MaaS is optimizing the vehicle routes to reduce the total travel cost with cooperation. For example, we know that platooning among la

Traffic signal control can mitigate traffic congestion and reduce travel time. A model-free reinforcement learning (RL) approach is a powerful framework for learning a responsive traffic control policy for short-term traffic demand changes without pr

An attempt is made to a new compaction model, which may agree well with experimental result when the particles are very adhesive. In our previous report1), we proposed a new model, in which adhesion force by liquid bridge is considered, for two-dimen
