摘要

After the 1995 Kobe earthquake, the expressway structures in Japan have been retrofitted and they willnot be seriously damaged under a certain level of strong earthquake motion. However, the moving stabilityof a vehicle has not been investigated yet. It has been reported that the drivers feel seismically inducedvibrations. Because of this phenomenon, they get some difficulties in controlling the vehicles duringstrong shaking. For a further safety promotion of the expressway networks, it is important to realize thedrivers' reactions under seismic motion. In order to investigate the drivers' reactions during anearthquake, the present authors have performed a series of virtual tests using a driving simulator. Based onthe results, traffic accidents may occur in case of heavy traffic because of strong shaking. The JapanMeteorological Agency (JMA) has a plan to establish a system to issue 'Nowcast EarthquakeInformation'. This information includes the estimated arrival time of the main shaking part of seismicwaves, which is calculated using the difference of the P-wave and S-wave velocities. Using both theIntelligent Transportation System (ITS) and the Nowcast Earthquake Information, it may be possible tosend an alert to drivers to make them be ready for shaking. In this study, the effect of early warning todrivers is investigated based on the driving simulator experiment. The reactions of drivers with/withoutwarning are compared for different caution time and traffic condition. From the experiment, the earlywarning is expected to be effective if it is issued to the drivers on the expressways before the arrival of Swave.
