Applications

Development Technologies

Commercialization and facilitation of compatibility technology, active head-

restraint, commercial vehicle AEBS, etc.

• Add new technology in NCAP

Major contribution to national agenda “Reducing traffic casualties by half”

Assessment Technologies

Apply assessment technology to verify emerging technology

Reflect assessment technology to global technical regulations and ECE

regulations in WP.29

• Vehicle compatibility, LDWS, AEBS

Develop safety regulations and test procedures

• AFLS (highway mode). LDWS, AEBS, blind-detection system

Page 16

Expected Outcome

Technological Aspects Verify emerging technology and eliminate unwanted effect by developing

assessment technology Reflect results to domestic and international safety regulations(WP.29 ECE R &

GTR) Reduce traffic accidents Lead world vehicle market by improved technology

Socio-economic Aspects Contribute to new traffic system with assessment technology and safety

regulations Improve national status in traffic accident by drastic decrease

• AEBS(18%), LDWS(12%) Contribute to reduce CO2 by improving traffic congestions due to decrease in

accidents
