Safety

The increasing in-vehicle information and safety systems tend to confuse and distract the
driver from his/her primary driving task. This paper develops algorithms for the real-time
supervision of the traffic and environmental scenario around the vehicle for the optimization
of the Human Machine Interaction. The proposed algorithms reconstruct the scenario using
stochastic motion models and Kalman filters, predict the intention of the driver using
Demspter-Shafer decision fusion and calculate the level of risk in using fuzzy logic. The
algorithms will be part of the Driver – Environment – vehicle state estimation in AIDE
Integrated project.

Rapidly developing economy evoked the increasing number of vehicles, and the urban traffic is already
overburdened. Nowadays if we cannot rapidly dispose the emergencies, such as traffic accident, vehicle
breaking, illegal driving and bad weather conditions, the traffic congestion will be diffused quickly, and
sometimes even worse to lead the local traffic paralysis. As to the emergencies have some
characteristics of the frequentness and uncertainty on time and space. It is a desirable problem
to solve among the major cities nation-wide that how to enhance the rapid response capability
to these emergencies, where the traffic policemen should appear immediately when they are
needed, how to avoid the diffusing of the traffic congestion and the traffic paralysis, etc.
Therefore we’ll introduce you the functions and characteristics of the Rapid Responding and
Disposing System of Road Traffic Emergency developed and used in the city of Dalian, China.
The followings are some details such as finding and disposing the road traffic congestion
rapidly, establishing and implementing the per-plans for special safekeeping assignments,
monitoring the illegal vehicles and traffics, real time traffic information transferring, and the
evaluating of the on duty policemen’s work.

We are studying safety driving support systems that are attained by exchanging
each vehicle's movement data through vehicle to vehicle (V-V) communication.
This paper describes a study on the communication protocol. First, the design
methodology for the physical and data link layer (L1 and L2) is described under
an ideal condition, without restrictions in other words, because the basic
specification of the communication system depends on these lower layer
protocols. Next, points for applying it to a practical system are described.

The fatigue of the driver is one of the factors of the traffic accident. And it is necessary to ease fatigue
during driving. In this research, we examined whether it was effective to give colors as a stimulation to
the driver in order to reduce the load while driving. We used the color that was one of visual information
as stimulation because 80% or more of external information is visual information. In addition, we used
the color of green because it is said that green has the effect of refreshing. We analyzed the effect of
color from beta-wave content, presumtion of autonomic nervos activity and change of mental load level.
The result of an examination using the driving simulator shows the defference of each index because the
color stimulation was given in addition to usual driving enviroment. It was shown that the color exerted
some influences on the driver while driving by this research.

According to the successful experiences of highway design in developed countries, elementary
truck escape ramp design schemes are given for China mountainous area’s highway,
based on different kinds of geological conditions, and considering highway factors. Constructive
advices in the design are given too. The study collected data for China Criterion of truck
escape ramp design, and will enhance the safety of mountainous area’s highway.
