face LAB is a product developed by Seeing Machines Inc., a spin-oﬀ company of the Australian National University (ANU). This system measuresthe motion of the face based on information from two video cameras that automatically track the person's face in real time. This software
captures the facial features 3 dimensionally from an image, extracts the facial features and tracks these features. When a facial feature changes
on the screen, it will keep tracking even when the head rolls fast or when part of the image of the face on the screen is distorted, by choosing a
new feature dynamically. The output data is; eye movement, position of the head, rotation, tightness of the eyelid, movement of eyebrows andlips and the size of the pupil (pupillometer).
A person’ s face naturally tells you a great deal about their mental state. By using this system we can measure a person's intentions and thedegree of attention from examining the person's countenance.

Vissim is an industry standard micro-simulation traﬃc software product. It
can simulate traﬃc ﬂows by taking into account the way individual vehicles
inﬂuence each other within a network. It is used in a variety of ways
including helping in the identiﬁcation of problems due to heavy traﬃc andcongestion.
Vissim can run complex traﬃc simulations including; bicycles, cars, buses,
taxis, short and long distance trains, which makes it possible to predict
delays in public transport due to congestion and verify the eﬀect of
introducing bicycle lanes.

14. Vehicle Dynamics Simulator
CarSim and TruckSim are vehicle dynamics simulation software systems
developed and commercialized by US company Mechanical Simulation
Corporation Inc. These software tools are used by automotive engineers toevaluate the dynamic behavior of vehicles under a variety of driving andenvironmental conditions (cars, trucks, buses, motorcycles). CarSim andTruckSim are industry standard products, used by over 30 auto
manufacturers, 60 parts manufacturers and 150 universities and research
institutes around the world. The products have an enviable reputation
within the ﬁelds of vehicle dynamics control engineering and R&D related
to ITS. These software products are also used in rollover car accident
analysis and road design.

15. Other Subsystems（Sound, Power source, DVR）

Power source system
A UPS (uninterruptible power supply) is connected between the
power source and the computer system in order to protect thecomputer system and the experimental data from any
unexpected power failure. The UPS can supply a stable powersource for 10~20 minutes, so providing the operators time to shut
down the system and return the motion platform into a settled
position.In addition, the operator can separate the ACC#1 andACC#2 into 2 steps, controlling the 6DOF motion platform andother motions (X-table/YAW-table, Vibration) separately.

DVR system（Digital Video Recorder）
Several CCD cameras are positioned within the cabin, DOME, andsimulation room to continuously monitor the system in operation.
There is a recording function, which along with the Data LOG
function can be used to research drivers' behavior.

17. Driving Simulation Standard Model
In addition to the ability to create VR models for driving
simulation, UC-win/Road is equipped with the following 4
standard model types. All of them are real time VR models thatcan make eﬀective use of the features of the driving simulator
modeled from real roads. It provides a ﬂexible driving
environment by means of the scenario function, environment
switching function and the switching of cabin and motion model.

■Urban Road VR Data

As part of the project we reproduced the urban area road network of the Chinese capital city having the "No. 3 loop line" of Beijing city
as the center. Modeling all lines' road signs, marked lines (Chinese GB5768-2009 criterion correspondence) and guide plates, andplaced them in accordance with local video coverage. Dozens of wide roads with widths of more than 4 lanes on one side and "solid
cross ‒ bridges" which are intersections of radiation path and loop line have been created, faithfully reproducing the roadinfrastructure, railroads and buildings. In addition to the landmark buildings, such as the venue of the 2008 Olympic the "bird's nest",
the 3D city model realistically reproduces Beijing’s urban loop line network and the overall sense of urban space.

UC-win/Road■Data collection system

Speciﬁcation：Feature to record the information related
to speed and vehicle in traﬃc ﬂow
Solution：A plug-in for exporting information related tothe coordinates and orientation of the driven vehicle,
its velocity, its steering angle, etc. has been developed(paid option). Traﬃc ﬂow and characters can also beexported. They can all be saved not just to a CSV ﬁlebut can also be exported in real-time using UDP via network.

■Mountain Road VR Data

This is a VR environment reproducing part of the national road G109. It has been designed to faithfully reproduce the road structure toprovide a realistic feeling of acceleration and centrifugal force to the driver, especially when the vehicle passes a curve of a diﬀerent
radius. The continuous curve in the VR space was created based on a video recording of the real road. The whole 3D environment was
created based on the on-the-ground research photos such as those depicting the gutter structure of the road cross section, drainage
ditches and the texture of the cut earth.

■Highway VR Data

An actual VR model of national road G110 was created. The conventional common national road with two-way two-lane has been
extended to 2 one-way two-lane roads, separated from each other but running in parallel. The data creation was based on the design
diagram of the extended road under construction. This model realistically reproduced the scene common to road construction sites inwhich passing vehicles are mainly large trucks. There are also various special environmental conditions built in such as rain and snow.
Even a frozen road surface can be experienced from the driver's perspective in the driving scenario. The VR data has been designed toprovide the optimum driving environment, allowing faithful reproduction of the vehicle behavior and driving sensation.

22■Inﬁnite Loop Road Data

This VR environment was produced to research ‘fatigue driving’ in which the driver keeps driving indeﬁnitely using the newly
developed "traﬃc connection" function. A typical Chinese cross-section is applied for the road structure and for the traﬃc ﬂow ofvehicles, road information was obtained from actual on-the-ground research which faithfully reproduces the traﬃc ﬂow.
