-The Future of Traffic Safety Through V2V (Vehicle-to-Vehicle)-

The diverse set of traffic safety devices are just one type of technology that goes into protecting us from traffic accidents. A vehicle approaching another vehicle without being able to detect it brings to mind traffic safety devices. Devices and systems that provide us with the most basic of safety options are devices such as seatbelts, airbags and ABS (Anti-lock Braking System). Recently, active safety devices are emerging such as V2V (Vehicle-to-Vehicle) that go beyond the traditional manual safety devices. Today we will take a look at the state of traffic safety and what the future holds through a few examples of V2V.

Cars Communicate! What is V2V and What can We Expect?

V2V is a technology that allows cars to send and receive information. V2V has come into the spotlight recently as a system that prevents traffic accidents by sharing speed and location information between cars that come into close proximity of each other. Korea’s ETRI (Electronics and Telecommunications Research Institute) developed VMC (Vehicle Multi-hop Communications) in May of 2011 and expanded the development of ITS (Intelligent Transportation System).

Currently in the US they have legalized the introduction of V2V technology and are recognizing and implementing the safety technology. The reason that V2V is receiving so much attention is because of the expected results that will follow the implementation of V2V. The first result expected to follow is the ability to share location information via Wi-Fi and receive and transmit traffic information within the range of Wi-Fi transmission. Also, it will be possible to protect passengers from accidents on a typical drive and prevent 80% of traffic accidents. In the case of car crashes, an environment is made to reduce injury by connecting via V2V and accessing pre-crash conditions and ‘preventing and or reducing dangerous conditions and accidents.

Because of these positive points, V2V is taking hold in Korea as well. In September, the Korea Expressway Corporation Transportation Center, part of the Korean Ministry of Land, Infrastructure and Transport (MLIT), began a research demonstration. Since July the MLIT has been conducting research by setting up wireless expressway communication base stations, radar and intelligent CCTV that communicate with approximately 200,000 cars daily on the expressway between Seoul and Suwon, Korea. The demonstration is being conducted using 100 automobile terminals. The participants in the demonstration drove the approximately 20km distance from Seoul to Suwon at speeds between 90 and 100km/hr and exchanged information such braking, sudden stops and distance between cars to check data on dangerous conditions and experience actions taken to deal with these conditions. The technology communicated with the terminals installed in the automobiles once every 0.1 seconds and exchanged information in order to provide information that can prevent accidents resulting from the carelessness of drivers.

The Current State of ITS (Intelligent Transportation System)

Aside from the example above, there are other diverse ways that ITS with V2V is being implemented to develop safe and efficient transportation systems. We will now take a look at some examples.

First, there are 5 main ITS service fields. Refer to the chart below to see what services are provided in each of the 5 fields.

  • The Services Provided in Each of the 5 ITS Fields 


As you can see, ITS services are being implemented in a wide range of fields from the traffic we maneuver every day to logistics.

  • Diverse Example of ITS at Work 

How might ITS be implemented in these diverse fields? Let’s take a look at a few examples.

1)    The Comfortable and Safe Residential Environment Constructed by LG CNS
I think we all remember the 2013 Boston Marathon terror attack. It is well known that it only took 4 days to apprehend the perpetrators. The reason they were able to catch the suspects so fast is due to intelligent CCTV. Intelligent CCTV makes analyzes images in real-time. Sound and actions can both be analyzed. Currently, intelligent CCTV is proving to be the representative ITS solution technology by allowing the analysis of high volumes of data and managing the results for implementation in industries such as service, security and logistics.

LG CNS provides services in 6 fields (transportation, safety, facility administration, information offering and infrastructure) that make up the Cheungla region U-City in Incheon, Korea. The Cheungla region transportation system automatically control traffic installations by collecting and processing traffic information with real-time signal control. Traffic flow is optimized for providing the real-time traffic information from the Incheon Transportation Information Center to the citizens. Also, they are able to crack down on traffic violations and impose fines while managing unexpected conditions, accidents and traffic congestion on the roads. More convenient public transportation is also possible through providing transportation information to bus passengers.

They are also able to search CCTV images and prevent crimes through monitoring pedestrian routes with cameras that are installed to monitor roads throughout the entire region. It is also possible to quickly handle accidents using cameras that can detect automobile registration numbers on main thoroughfares.

But intelligent CCTV is not only applicable for transportation. Solutions are being developed for business applications that can improve customer satisfaction by assessing visitors to stores and analyzing and categorizing consumers.

2) Seoul Electronic Road Signs
With LED light road signs that are easy for drivers to see, various colors and figures can be used to intuitively provide drivers with traffic information. Intelligent road signs demonstrated in 2002 that traffic congestion costs could be reduced by USD 570 billion. Since then, there has been an increase in the installment of electronic road signs on main city streets in Seoul. Electronic road signs are a key example of ITS and help in the understanding of traffic information as well as reduce traffic congestion.

What We Can Expect from V2V Technology at the Center of Future Traffic Safety Solutions

As we look at examples of ITS in our lives, I wonder what role V2V will play in future traffic safety solutions. As we can tell from legislature requiring the implementation of V2V in the US, V2V has become a major trend in traffic safety. Especially, as V2V increases in efficiency and becomes a leader in future automobile safety, interest in V2V is growing. However, there are still a few issues to be resolved in order for V2V to be put into common use. Some of these issues are infrastructure construction, product costs, personal information protection, embedding the technology in 70% of vehicles on the road and settling on a standard frequency for transmissions as well as other privacy issues being resolved and effective promotion of the technology.

In line with the high rate of smartphone use in Korea, the development of technology connecting cars and smartphones is also increasing. This technology is forecasted to be in use within the next 5 years. It is also likely we will soon see an increase in not only V2V but also in V2I (Vehicle-to-Infrastructure) technology, which allows vehicles to communicate with the infrastructure on the roads. If this is the case, we can expect a reduction in traffic jams and a wide range of new traffic safety regulations.

There is still a lot to be done in order to resolve the issues surrounding the common use of V2V. However, with increasing interest and efforts, V2V has firmly become the foundation of traffic safety technology.
