V2X Next wave of transportation

Advancement in the societal and new market trends leading to revolution in personal mobility and vehicular transport system. Societal trends such as rapid growth of urbanization putting pressure on current transportation setup, which is growing less compared to the demand, tough emission and energy related regulation are also impacting transportation systems. Apart from this, market trends as advancement of automated driving, real-time and open data accessibility, enabling more effective use of transport assets and also affecting the current transportation systems.

Such trends are enabling a move near to sensitive and intellectual transport infrastructure, with properties of accident-free transportation, supporting higher traffic flow, higher vehicle utilization and more efficient/greener transport. Hence, communication technology such as Vehicle-to everything (V2X) communication, will play a major role to attend these properties.

V2X, means 'vehicle to everything', and it is the part of car communication system. V2X enables autonomous driving with properties as low-latency and high-reliability links. It uses high bandwidth and data flow from sensors and other connected sources.

V2X consists of various components such as vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-pedestrian (V2P), and vehicle-to-network (V2N) communications. It is a multilayered ecosystem and enables cars to talk with other cars, infrastructure like traffic lights or parking spaces, and to datacenters via cellular networks.

Various car makers and vendors are implementing and experimenting with V2X, V2I, V2V technologies, some of which are highlighted as below.

Qualcomm Technologies collaborated with Panasonic and Ford Motor to launch cellular Vehicle-to-Everything (C-V2X) technologies in Colorado, starting the only U.S. deployment of C-V2X technology.

Audi mounted V2I (provides information based on traffic lights) in few of its Audi A4 models in 2017. It is a traffic management system observing traffic lights using 4G data connection and sending real- time signals to car.

Cadillac CTS sedans launched V2V security technology in US during 2017. It comprises solution of NXP's DSRC and GPS for transmitting and receiving about 1000 messages per second from different vehicles, which are about 300 metres apart. V2X software contains 10 DSRC V2X solution comprising of junction's crash caution, dangerous location notice and emergency vehicle warning.

In Aug, 2017, Hyundai, Kia Started V2X communication solution for a 14-kilometer section of road along with seven junctions in Hwaseong, located in Seoul, Korea for testing autonomous car.

Volkswagen is working on model with IEEE 802.11p-based pWLAN to enable vehicles to communicates with each other. It can help to identify on road situations as, car making emergency stop after its sensors detects obstruction on road.

According to the market research firm MarketsandMarkets, the V2X market is expected to attend CAGR of 17.61% from 2017 to 2025, total market size expected to reach $99.55 Bn by 2025 from $27.19 Bn in 2017. Increasing demand for real-time traffic control, event alerts for increasing public safety, rise in government funds for enhanced traffic management, and the advancement of connected vehicles are some of the leading factors driving the growth of V2X market. Also, growing environmental concerns and extreme competition between car manufacturer are few other factors impacting the growth of V2X.

V2X technology consist of opportunity to transform automotive industry using autonomous cars and help in providing predictive maintenance using real -time monitoring. Though, it possesses challenges of dearth of standardization, lack of acceptance of V2X technology and security of data generated by vehicles.

Upcoming 5G infrastructure expected to provide bandwidth for large amount of connections in a small area enabling individual vehicles to capture more data about their immediate surrounding. V2X technology provide enormous technical and economic advantages compared to other dedicated vehicle connectivity technologies for different stakeholders such as road operators, automakers and mobile operators. It can support wide range of use cases covering safety, navigation and integrated transport systems as compared to different alternatives. 5G cellular system provides advantage of handling all the V2X applications in end-to-end manner using single technology, which makes it scalable and future proof.
