Travel Times Surveys

Travel time surveys are undertaken using a GPS antenna and a small standalone datalogger.

The Datalogger records vehicle position, vehicle speed and vehicle heading at 1 second intervals allowing detailed plotting of the vehicle’s travel times, and speeds.

Once the data has been logged it is transferred to a laptop computer for further processing.

The Datalogger is powered from a vehicle cigarette lighter output with the GPS Antenna simply attached to the vehicle windscreen by a suction cup.

Once the data has been collected it is typically plotted in Excel graphs for more detailed analysis.

Typical outputs include:

• Time vs Distance for each direction of travel;
  

• Speed vs Distance for each direction of travel; and
  

• Tabulations of travel time between previously established waypoints.
  

Examples of the typical outputs available from the travel time surveys are shown below.
