In December 2018, ZERO-SUM, LTD. and TOYOTA InfoTechnology Center Co., Ltd., with the support from the Ministry of Internal Affairs and Communication, JAPAN and in collaboration with Connected Solutions Company, Panasonic Corporation and with approval from the Amdavad Municipal Corporation in INDIA, conducted a demonstration experiment showcasing an emergency vehicle priority system that uses a UHF band based Japanese originated international standard V2X communication technology.
This experiment demonstrated the use of an emergency vehicle priority system in which an emergency vehicle such as ambulance and traffic information display boards communicate with each other through the UHF band using V2X communication technology originating from JAPAN and International standard. This is the first demonstration of its kind in the world on a public road.
Goal of the experiment
This demonstration experiment that uses the application of UHF band V2X communication technology, aims at addressing and solving one of the most important challenge faced by emergency vehicles such as ambulances today, i.e. reaching their destination in the quickest time possible which is sometimes not possible owing to traffic congestion.
This technology prompts traffic information display boards installed on the road to display information of an approaching emergency vehicle. Upon the detection of an emergency vehicle, the display boards will inform motorists on the road to make way for the priority passage of the emergency vehicle, thereby enabling the emergency vehicle to get free passage and reduce the travel time to its destination safely. The demonstration used UHF band frequency for the communication of information, which due to its high penetrability through buildings and natural obstructions and less interference from other devices is the most ideal for urban areas in ASIA where there is a higher urban populace and buildings alongside the roads that are densely populated.
Outline of experiment
A V2X communication device was installed on an emergency vehicle and on traffic information display boards. When an emergency vehicle equipped with a V2X communication device approaches the traffic information board on which a V2X communication device is installed, the V2X devices communicate with each other and the information that an emergency vehicle is approaching is immediately displayed on the traffic information board for the convenience of motorists on the road, enabling them to make way and allow the priority passage of the emergency vehicle. This system has helped demonstrate that a priority system for emergency vehicles on public roads can be implemented.

Location of experiment
The experiment was conducted on the West Bank of the Riverfront Road in Ahmedabad, which is the capital of the western state of Gujarat in INDIA.
The River front Road runs along the western banks of the Sabarmati River which flows through the center of Ahmedabad City.

Results of the experiment
Upon completion of the demonstration it was found that the emergency vehicle priority system that uses UHF band and the V2X communication technology which is similar to the Japanese “700 MHz band Intelligent Transportation Systems Standard (ARIB STD – T109)” is very stable as the communication between the V2X devices was confirmed. Furthermore, it was also observed that by displaying the emergency vehicle approaching information on the traffic information boards, most motorists move aside to give priority passage to the emergency vehicle, thereby enabling the emergency vehicle to run smoothly. The UHF band used in the demonstration experiment was acquired under an experimental license from the Wireless Planning and Coordination (WPC) Wing of the Ministry of Communications, Department of Telecommunications, INDIA.

The next deployment
In the next phase of the experiment, more methods on how the emergency vehicle travel times can be further shortened will be explored. In addition to studying the effects of the experiment already conducted, further examining and customization of V2X messaging sets will be undertaken basis the local requirements in INDIA. The next deployment will also aim at integrating a signal control system with V2X communication technology so as to provide stoppage free green corridor passage to emergency vehicles. In furtherance, upon completion of the experiment, a study to expand the project to cover other key prominent locations in which we can implement such V2X communication technologies will also be explored.

Explanation of terms
Amdavad Municipal Corporation, Ahmedabad city, Gujarat State, INDIA
The Amdavad Municipal Corporation is responsible for the civic infrastructure and administration of the city of Ahmedabad which is the largest city in the state of Gujarat, INDIA. Ahmedabad city has a population of 5.6 million people and is the seventh largest city in INDIA. Several Japanese automotive companies in recent years have setup their manufacturing facilities around Ahmedabad City. Ahmedabad city is also one of the first cities selected under the Smart City program implemented by Prime Minister Narendra Modi and has been at the forefront in the implementation of smart technologies for the betterment of its citizens.
UHF (Ultra-High Frequency)
Ultrashort frequency band. Radio waves with frequencies range 300 MHz to 3 GHz fall under this category. Two of the key characteristics of radio waves in the UHF band is the long communication distance range, and its ability to penetrate natural and man-made obstacles. It is used in mobile phone communication, wireless LAN, wireless communication for automobile and mobile communication for business use.
V2X – Vehicle to Everything(X).
V2X is the collective term for technologies and systems for exchanging information between automobiles and other automobiles, automobiles and roadside equipment & automobiles and pedestrians using wireless communication system.
700 MHz Band Intelligent Transportation Systems Standard (ARIB STD-T109)
It is a standard compiled by the Association of Radio Industries and Businesses, Japan (ARIB) to support safe driving using vehicle-to-vehicle and vehicle-to-infrastructure communication system. The exchanging of information will enable the prevention of traffic accidents and help realize safer driving. The safe driving support services started from Japan and has been in use since 2015.
The WIRELESS PLANNING & COORDINATION (WPC) Wing of the Ministry of Communications, Department of Telecommunications, INDIA is the National Radio Regulatory Authority responsible for Frequency Spectrum Management, including licensing and caters for the needs of all wireless users (Government and Private) in the country. It exercises the statutory functions of the Central Government and issues licenses to establish, maintain and operate wireless stations.
“Research for the overseas expansion of ITS technologies in Japan”
“Research for the overseas expansion of ITS technologies in Japan”, is a research project funded by the Ministry of Internal Affairs and Telecommunications, JAPAN.
