This system employs traffic data from sensors to project the travel time from a set of given origins to the target destination. The field test results from the highway segment along EB I-70 from MD 32 to I-695 reveal that prediction of travel times under moderate and stable traffic conditions is likely to yield an acceptable level of reliability. However, much remains to be improved for achieving reliable prediction of travel times under congested and unstable traffic flows.

One of the reasons is the frequent switching between acceleration and deceleration, and the smooth control for the driving stability and comfortable at low speeds is more difficult than at high speeds. This paper presents a fuzzy longitudinal control system for car-following. This controller achieves the main functions of both adaptive cruise control (ACC) and Stop & Go control. For constructing the vehicular longitudinal control system, we use vacuum boosters to control the throttle and the braking pedal, thus circumventing the technical difficulties of using engine management system and anti-brake system.

However, we have to take into consideration noise pollution which effects local inhabitants. For instance, setting the sound level to a minimum, or stopping the sound at night. Due to this the controller is not sufficient for visually impaired people. Another problem arising at present is that the acoustic signal controller cannot be installed in populated area because even during the daytime guidance sound is considered noise pollution. Therefore, we have developed a new acoustic signal controller to solve these problems.

We developed the HMI technology that notifies route guidance to the driver by use of seat vibration. This HMI has the following characteristics to the conventional car-navigation systems. The route guidance (for general way): The guidance way is indicated by vibration of each motor right or left. Moreover, the distance to a crossing is indicated by change of vibration. The route guidance (for freeway): navigation systems changes guidance start distance in consideration of the difference between a general way and a free way. By using this HMI, the driver can know the guidance way and the distance of crossing, without verifying the car-navigation screen. As this result, eyes movement of the driver decreased and we verified that a driver's operating duty was mitigable.
