What is an Advanced Traffic System?

• ITS stands for intelligent transportation system which is a ubiquitous advanced traffic system in the 21st century that can effectively control traffic jams and significantly improve the reliability by applying advanced technologies such as information/ electronics/ communication/ controls to the existing transportation elements such as roads, cars and freights. It can maximize the efficiency of traffic such as improvements of traffic conditions, convenience of traffic use and energy saving.

Composition

• It is mainly comprised of three phases – first, the traffic information is collected from a collection device such as CCTV, second it is analyzed and processed by the system and third, it is provided to the users.

Background

• As of the end of 2022, Ulsan city had the highest number of vehicles per household (1.24 vehicles) and the highest traffic congestion cost among the seven metropolitan cities. The traffic volume has been increasing by more than 2.5% annually, and the number of registered vehicles has been steadily rising by more than 1.2% each year, leading to a worsening traffic situation.
  
  
• For this reason, the traffic condition is increasingly deteriorated. To resolve this problem, each year, the city government is investing lots of money in building new roads and so forth. However, the effect of such efforts was very limited in resolving the problems and as the citizen’s demands for new traffic methods were increased, since April, 2001 until April, 2005, an intelligent transportation system(ITS) was implemented and gradually expanded each year.
• Since 2002, Ulsan city has implemented an intelligent transportation system (ITS) and established the Ulsan Traffic Management Center (UTMC). As the first among metropolitan cities to implement an advanced intelligent traffic information system, Ulsan is setting exemplary standards for ITS not only in Korea but also for major cities worldwide.
  
  
• Especially, according to the transportation policy of Ulsan city, along with the traffic information service, the traffic signal system is comprehensively monitored by our system that can controls a flexible flow of the traffic. Traffic loads in the congested areas are distributed, and the traffic jams are eliminated. The traffic flows between the metropolitans and the real time road traffic information in interconnections with the signal control systems are supplied by combining all the information occurring on the roads. From now on, the Ulsan traffic management center will implement an advanced intelligent information system to supply more efficient traffic information.
