ITS GREEN SAFETY
New Public Private Cooperation activity on Cooperative ITS
“ITS Green Safety Consortium” started in 2012
Field Operational Test from 2012
Interim report and Showcase at ITS WC Tokyo 2013
Deployment target after 2014
For a Greener & Safer Traffic Society
ITS GREEN SAFETY is a Public-Private collaborative project that aims “For a
Greener and Safer Society” using Cooperative ITS by improving traffic concerns.
Cooperative ITS communicates to drivers necessary real time information to
help realize not only safer transportation and people-friendly environment but
comfortable driving by road Infrastructure to Vehicle (I2V), Vehicle to
Vehicle(V2V) and Vehicle to Pedestrian(V2P) communication.
ITS GREEN SAFETY SHOWCASE provides experiences of the five cutting-
edge cooperative ITS showcases from commenced services to under
development on Tokyo Metropolitan public roads.

Next Generation DSSS (I2V)
Introduction of Demonstration
Next-generation Driving Safety Support Systems (DSSS) consists of
the technologies including devices for I2V communication via
infrared beacons and radio waves, and roadside sensing equipment
to detect vehicles and pedestrians.
In this demonstration, participants experience DSSS on ordinary roads
around the venue with image display and audio guidance designed for
next-generation DSSS.
The demonstration includes the systems which are based on the
information from infra sensors such as Right Turn Collision Prevention
System and Left Turn Collision with Motorcycles Prevention System.
The demonstration also includes Signal Information Drive Systems
(SIDS) for ensuring safe and smooth flow at intersections and reducing
CO2 emissions by providing signal information.

Introduction of Demonstration
Study Group for Promotion of Advanced Safety Vehicle (ASV), a joint
initiative involving industry, academia and government, has developed
communication-based advanced safe driving assistance systems.
The demonstration shows how driving assistance systems with vehicle-
to-vehicle and vehicle-to-pedestrian communication work in different
traffic conditions.
The demonstration provides drivers with information on potential
hazards such as the approach of vehicles and pedestrians in order to
prevent accidents caused by driver oversight due to low visibility or
inattention.
In order to support drivers, vehicles equipped with the systems can
recognize the traffic conditions around them and support drivers even
when visibility is low.

Experience World first commenced Cooperative ITS to support safer and comfortable driving on Tokyo Metropolitan Expressway
Experience under experiment Cashless Payment Service
“ ITS Spot” 3 major services Dynamic route guidance Safety driving support Toll collection
【Safety driving support】
Other services Collecting probe data Connecting to the internet
1600 Rode Side Equipments deployed mainly on expressway
19 manufacturers marketed On-Board Units
Under experiment services Cashless payment service Logistic vehicle fleet management
Services commenced nationwide in 2011
Introduction of Demonstration
ITS Spot services, the world's first vehicle-infrastructure cooperative
system, started nationwide in 2011.
Both in the long and short course of this showcase, participants will
experience the Dynamic Route Guidance rendered according to road
congestion, the Safe Driving Support warnings to driver according to
his driving speed against road alignment, events occurring on the
Tokyo Metropolitan Expressway which have more than 1 million
vehicles of daily traffic.
If you take a long course, cashless payment service at parking-lot using
the ITS Spot (DSRC) OBU and a credit card, which is currently under
technical study, is also demonstrated. If you take a short course, you
enjoy the ITS Spot services with taking a ride on a next-generation fuel
cell bus.

1. ACC cooperative service
ITS Spot gives information to adapt ACC settings (speed or time gap) Time gap would be modified
ITS Spot gives information to adapt the setting of CACC. Platoon stability is enhanced
Control the following time gap to diminish shockwave propagation
2. CACC cooperative services
ACC(Adaptive Cruise Control)
The ACC system monitors the position of the vehicles ahead, and keep driving speed or time gap stable
CACC(Cooperative Adaptive Cruise Control)
CACC is able to share the acceleration/deceleration data, therefore vehicle following time gaps is stabled precisely
Demonstration for congestion mitigation service is now operating. ACC system should be switched on*
Smartway with ACC/CACC (I2V, V2V)
Experience driving practice to realize smooth traffic flow with ACC/CACC vehicles by applying V2I/I2V cooperative system
32
Sag section Where vertical Alignments change gradually towards up, about 60% of congestion at interurban expressways occur
Introduction of Demonstration
Participants experience the demonstration of congestion mitigation in
sag sections of expressway in a vehicle equipped with Adaptive Cruise
Control (ACC) / Cooperative-ACC (CACC).
The relevant information about ACC/CACC settings will be provided via
ITS Spot.
Receiving the information on the car navigation screen, the
participants experience ACC to adjust and maintain the distance
between cars, and CACC to synchronize the movement of vehicles in
a platoon using vehicle-to-vehicle communication.

Experience safe and comfortable urban transportation by new traffic information networks
Introduction of Demonstration
Experience next-generation ITS services offered by linking ITS Spot
and smartphones.
Participants make a round trip by bus from Odaiba to Umihotaru.
During the trip, ITS Spot information (e.g. wide-area traffic jams,
dangerous areas) and local information provided by a cellular network
(e.g. traffic signs, landmarks) is displayed on participants’ smartphones,
and they experience a safer, more comfortable highway drive suitable
to place and time.
Moreover, new services such as emergency evacuation information in
the undersea Aqua Tunnel and a stamp collection rally at ITS Spot is
demonstrated.
Complementary use of ITS Spot and mobile networks - Traffic information from ITS Spot displayed on smartphones in English,
Chinese and Japanese
- Local information provided continuously via a mobile network
- Collect a series of stamps at ITS Spot
- In addition to smartphone sensors, information acquired from ITS Spot is
used to accurately identify position in the tunnel. 39
