Study on the development of safety grade model for roads in Korea using digital tachograph and traffic accident data
Språk: Engelska Utgivningsinformation: Linköping : Statens väg- och transportforskningsinstitut, 2018Beskrivning: 1 sÄmnen: Onlineresurser: Sammanfattning: A Digital Tachograph (DTG) attached to a business vehicle is a device that stores vehicle driving record in real time. The DTG can record the vehicle's GPS position, driving speed, revolutions per minute (RPM), vehicle status, brake signal, azimuth, and acceleration. Korea Traffic Safety Authority (KTSA) collects DTG data and uses the collected DTG data to generate eleven dangerous driving behaviors such as speeding, rapid acceleration, rapid deceleration, sudden lane changing, and sudden turning. The number of eleven dangerous driving behaviors can be used to identify the driver's driving behaviors. Therefore, it is expected that the number of dangerous driving behaviors will be matched with the road segment and it will be able to identify the dangerous driving behavior occurring in a specific road section. The purpose of this study is to construct road safety performance functions based on eleven hazardous driving behaviors and traffic accident data in order to establish safety grade model of roads in Korea.A Digital Tachograph (DTG) attached to a business vehicle is a device that stores vehicle driving record in real time.
