The municipal government of Seoul said Thursday it plans to halve the number of traffic deaths over the next four years by taking more safety measures.

Under the traffic accident prevention plan, the city will push to bring down the current traffic death rate of 4.2 per 100,000 people to 2.1 by 2018.

To that end, the city plans to increase the number of special traffic zones to better protect children and elderly people.

The plan was one of the 25 key policy goals the municipal government announced in Thursday's four-year policy map, which is expected to cost the city around 8.4 trillion won ($8.2 billion).

Seoul Mayor Park Won-soon announced the policy package with special focus on citizens' safety, welfare and economy, after being re-elected for a four-year term in the regional election in June.

The policy map also includes the city's push to boost the number of tourists to Seoul to the annual level of 20 million by 2018 as well as a plan to cut the volume of the city's ultrafine particles by 20 percent.

As part of welfare efforts, the city will provide more public child care services as well as supply more rental housing units for young people, newlyweds and the elderly.

The metropolitan city government plans to finalize the four-year policy map in November after taking feedback from Seoul citizens, the city noted. (Yonhap)
