B. Operation

Advanced signal control system leading to effective traffic control of trunk roads

Improved traffic of trunk roads with a real-time signal control

Improved traffic by providing the drivers with real-time traffic conditions for each route.

Providing a real-time traffic information (normal, slow, congestion) with 4000 units of OBE and 37 sets of VMS for smooth traffic.l

Maintains the punctuality & operation information leading to enhanced usage rate /convenience.

  • Close operation monitoring by route (965 buses over 94 routes) and control system
  • Leading role in partial state-financed system / operation, schedule, and statistics
  • Enhanced user's convenience and usage rate, providing bus operation information based on BIS ( Bus Information Systems)
  • BIS information
  • Operation schedule: estimated arrival time (in minutes)
  • Search: location of bus, route and transfer points, etc.

Provision of day-to-day information through ITS system aimed at improving living standard of the citizens.

  • Bus information electric sign (965 sets): Daily information and PR material
  • Traffic, culture and weather information through the cell phone

Evaluation of ITS pilot projects

  • Evaluated by Korea Research Institute of Human Settlements / Managed by Ministry of Construction and Transportation (MOCT)
  • Period: Oct. 03 - Jul. 04 / Analysis of effect for construction of advanced traffic model city
  • Analysis method: Pre (2001) / Post (2003) investigation comparison analysis
