Traffic monitoring system in Korea

Traffic volume is used as basic data for road and transportation planning, design and policymaking. Two survey methods are used: continuous or permanent survey and coverage survey. The continuous or permanent survey is taken to investigate data around the clock for 365 days while the coverage survey is to conduct a sample survey several times during the year. The continuous or permanent survey is designed to investigate the volume of traffic during a year by installing fixed instruments at some important points on road networks. It is one of the most ideal methods, but requires a great deal of costs. The coverage survey is designed to extensively ascertain the overall status of road uses in all the sections that need basic traffic data. The data collected through continuous or permanent and coverage surveys are provided to users after analysis and statistical processing. Against this backdrop, this paper aims to deal with Korea's traffic survey systems.
