In Jeju, the fantasy of turning all traffic lights green in an emergency is real

JEJU, South Korea: The telecom advertisement shows an emergency vehicle rushing a pregnant woman to a hospital, and thanks to a smart transport system, all the traffic lights are green. Such a system is not a dream of the future; it currently exists on the southern resort island of Jeju.

Prioritized signal services for emergency vehicles are part of the cooperative intelligent transport system (C-ITS) on Jeju Island, which aims to become the country’s leading smart city.

Jeju Special Self-Governing Province said a 25 billion won (US$22 million) C-ITS pilot project was successfully completed on 300 kilometers of road over three years through 2020.

“C-ITS serves as essential part of a smart city and in particular, autonomous driving requires a well-established communication system between roads and vehicles and between vehicles,” Jeju Governor Won Hee-ryong said in a recent interview.

Intelligent transport systems (ITS) are being built in many global cities while C-ITS pilot projects are underway overseas, in places such as the United States, Europe, and Japan, according to the traffic information center of Jeju Municipal Police Bureau.

ITS is a system in which fixed roadside equipment collects transport information and delivers it to vehicles through a traffic center, while in C-ITS, the center and vehicles ahead collect real-time transport information, such as traffic conditions, sudden stop, and fallen objects, that they deliver to vehicles behind to prevent unexpected situations, the center chief Kang Su-cheon said.

Jeju city installed on board units (OBUs) on 3,000 rental cars and 133 road side units (RSUs) in fixed positions on the roads and used them for communication and data exchange with vehicles. The center provides real-time information to the driver through RSUs, Kang said.

Other equipment includes 41 units of CCTVs, 48 incident detection devices, nine pedestrian detection devices and road weather information systems with visibility and road sensors in 14 locations.

“The central control room can monitor the devices and thousands of cars driven by tourists. The vehicles send and receive information through the central system and between each other so drivers can be told in real time of dangers or obstacles on the road ahead or the pedestrians on the next crossing,” he said.

Sixty-five percent of tourists to Jeju use rental cars to move around the scenic island and traffic accidents have been on the rise.

The number of car accidents involving C-ITS equipped rental cars fell by 19 percent, compared with vehicles without C-ITS terminal in the year through October 2019, the center said.

In Korea, C-ITS test programs are still under way in the capital city of Seoul, the southeastern port city of Ulsan and Gwangju, 330 kilometers south of Seoul. A C-ITS demonstration project was completed in Daejeon, 164 km south of Seoul, according to the Ministry of Land, Infrastructure and Transport.

The government plans to begin constructing C-ITS infrastructure for passenger vehicles, not rental cars, in Daejeon in the third quarter based on accumulated data of local C-ITS test projects, an official at the transport ministry said.

No further details about the Daejeon project were given.

Establishing the C-ITS infrastructure is essential to operate autonomous vehicles in the long term, the official said.

Jeju was designated as a pilot zone for autonomous vehicles in December last year.

The city plans to test cooperative autonomous driving by providing signal information to vehicles through the traffic information center as early as August.
