This study proposes a driving assistance system to inform the notch operation timing for train drivers. The assistance system indicates visually the notch-off position where the driver releases the accelerator. The notch-off position is calculated by the present vehicle acceleration, velocity and position by assuming the constant acceleration. The assistance system also indicates the brake onset and the predicted stopping positions. Two experiments are conducted by using the train-driving simulator. One experiment examines the effects of the notch-off and brake onset timing on the vehicle velocity and the running time. The assistance system makes it possible to adjust the vehicle velocity and the running time. The other experiment examines the three running patterns by combination of the notch-off and the brake onset positions. With the time recovering pattern, which is combination of the higher notch-off velocity and the later brake onset timing, the assistance system realizes the shorter running time in comparison with the standard running pattern. With the energy saving pattern, which is combination of the lower notch-off velocity and the later brake onset timing, the assistance system prevents the time delay by the later brake timing even if the velocity is lower than the standard running pattern.

This study proposes the braking assistance system for train drivers when stopping at a station to prevent the drivers from overrunning and running time delay. The assistance system informs the driver visually of the brake onset position, which is calculated by the assumed deceleration, the present vehicle velocity and the desired stopping position. This study conducts two experiments using the train-driving simulator with three participants. One experiment examines the effects of the driving assistance system on the braking behavior with the mental calculation, which assumes the mental workload. The assistance system makes it possible to decrease the dispersion of the brake onset timing and the running time. The other experiment examines the effects of the brake onset timing on the running time and the safety margin to make the vehicle stop at the desired position. The brake onset timing is adjusted by changing the assumed deceleration. Obtained results show a good correlation between the assumed deceleration and the running time, and the later brake onset timing contributes the shorter running time. In addition, a good correlation between the assumed deceleration and the minimum value of the predicted stopping position, i.e. the safety margin, is also observed, and the later brake onset timing deteriorates the safety margin.

鉄道の安全性確保のために, 列車運転士には判断に関するヒューマンエラーを犯さないことが強く求められる. 列車運行時のヒューマンエラーを防止するためには, 人間の特性を考えた運転支援システムの開発が必要である. このようなシステムを開発するにあたっては, 運転操作と認知, 判断にともなう脳機能に着目する必要がある. 本論文では, 列車運転中の運転士の高次脳機能を, 機能的近赤外分光 (fNIRS) 装置を用いて計測した. 運転中の脳機能活動を抽出するために, ウェーブレット変換による多重解像度解析を適用することを提案した. 運転シミュレータを用いた実験の結果, 提案の方法により運転中の高次脳機能を評価できることを示した.

BCI (Brain Computer Interface) is a system that controls machines and devices by extracting neural information from human brain activity and inputting it to machines. BCI system can be used to feedback the brain activity level to users so that they can control their brain activity, which is called NFB (Neurofeedback). The NFB system is expected to make better condition for ASD (Autistic spectrum disorder) and ADHD (Attention deficit hyperactivity disorder) patients. The NIRS-NFB system measures the brain activity by using portable NIRS. The measured brain activity can be inputted to various machines and devices (display monitor, toy car and video game). To evaluate the effectiveness of the developed system, we conducted experiments of NFB training for ASD participants. It is shown that more brain activity can be observed after the NFB training for ASD participants. Those results show that the developed system is effective in the NFB training for ASD participants.

シミュレータにおいて、運転タスクに応じたドライバーの脳活動を、機能的近赤外分光装置fNIRSで計測した。通常走行に比べ、狭路走行と先行車追従走行では、前頭外側部の賦活量がより大きくなることを確認した。さらに、運転中に注意課題を与えた場合の注意力喚起に起因する賦活を、運転タスクの差から見出した。

Several methods are proposed for investigating the complex traffic flow. However, the dynamics of vehicle and the driver's characteristic, which are important factor for the traffic flow analysis, are not considered enough so far. This paper describes a new concept for simulating complex traffic flow by multiagents. The agents are considered as a kind of artificial life (A-Life) and they behave based on their own knowledge independently. Drivers, vehicles, roads and traffic environment, which are essential elements in our simulation, are defined as the agents. The vehicle agent combined with a driver agent works based on driver's region of sight and their own characteristics. The road agent communicates with the vehicle agent responding velocity, position of the vehicle. The effectiveness of our new method for modeling the traffic flow is shown by simulation study.
