Factors influencing traffic co-ordination

A major objective of computerized traffic control is good co-ordination between signals to minimize delays for motorists travelling on major streets. However, no matter how sophisticated the equipment, green lights are not possible for all traffic all the time.

Many factors influence co-ordination, including:

  • Direction of the major traffic flow
  • Changing traffic volumes throughout the day
  • Large number of vehicles turning
  • One-way or two-way streets
  • Distances between traffic signals
  • Left-turn arrows
  • Heavy pedestrian volumes
  • Vehicles speeding or travelling too slowly
  • Bus manoeuvres
  • Heavy trucks
  • On-street parking
  • Emergency vehicle pre-emption ( green light for emergency vehicles)
  • Collisions
  • Equipment malfunctions
  • Changes in signal timing plan

 Scheduled changes you might notice:

  • Presence or absence of left-turn arrows
  • Longer or shorter green lights
  • Changes in co-ordination between traffic signals
