This paper presents a travel time prediction model and evaluates its performance and transferability. Advanced Travelers Information Systems (ATIS) are gaining more and more importance, increasing the need for accurate, timely and useful information to the travelers. Travel time information quantifies the traffic condition in an easy to understand way for(More)
This paper studies the effect of rain on travel demand measured on the Tokyo Metropolitan Expressway (MEX). Rainfall data monitored by the Japan Meteorological Agency's meso-scale network of weather stations are used. This study found that travel demand decreases during rainy days and, in particular, larger reductions occur over the weekend. The effect of(More)
In the sustainable ITS project at the Center for Collaborative Research, the University of Tokyo, an experiment platform is developed for drivers' characteristics analysis on the moving-based driving simulator. In the upper-level microscopic car traffic flow simulator, a prototype driver model and vehicle dynamics model are developed with flexibility in the(More)
In this paper, we show the outline of our research on interactive traffic environment, under which we are developing mixed reality traffic experiment space. In order to develop sophisticated ITS applications, it is very important to analyze human factor, but there is few method to obtain human factor, thus, we have decided to create interactive traffic(More)
This study develops a microscopic traffic simulation model (KAKUMO), which is built into a mixed reality experiment system under an interactive traffic environment. We are developing a mixed reality experiment system to examine several human factors such as driving behavior and travel choice behavior, which are required to design and evaluate various ITS(More)
To alleviate urban congestion, macroscopic feedback control strategies have recently introduced which rely on real-time observation of relevant spatially aggregated measures of traffic performance. Ample monitoring of the system is necessary for those strategies to be successfully implemented. An efficient and practical methodology is developed to estimate(More)
INTRODUCTION IN the field of mobile communications, in response to reduction of bit cost and demands for QoS (quality of service), the needs for broadband communication are getting respectively stronger. Under these circumstances, standardization work of voice transmission by high-speed wireless communication technology and IP (Internet Protocol) is being(More)
