Purposes of Travel Time And Delay Study

Purposes of travel time and delay study

  • Travel time being a good indication of efficiency of roadway.
  • Before and after studies, utilising data on travel time and delay, are used to determine effectiveness of a traffic improvement, such as parking restriction, signal timing, new one way street, etc.
  • To determine the need for traffic signals.
  • Information on amount, cause and location of delays helps in locating ‘congestion spots’, where proper remedial measures can be taken.
  • Economic studies such as cost-benefit analysis utilise travel time and delay data.
  • Traffic assignment is based on speed -delay characteristics.
  • Sufficiency ratings or quality indices methods based on travel time, are used to compare different roads and assess the quality.
