iTREC Travel Time GPS Software

A stand-alone software package to easily collect, analyze, and report travel time survey information using a GPS.

• Developed by HDR/iTRANS year 2000

• Widely used by many government agencies, universities, and traffic software developers.

Are you tired of…?

 • Using a stop watch and looking down at the

time at a specific location• Performing additional runs because you

weren’t able to collect the correct time• Conducting Travel Time Runs with two

people in the vehicle• Spending a lot of hours inputting the data

and analyzing the data.• Paying too much for GIS Software licenses• Keeping up to date with the latest GPS

devices

Would you be happy if…?

 

• No third-party GIS software required• No GPS experience required• Data collected by driver alone• GPS based software does not require

mechanical connections to the vehicle• Use your own GPS system, or purchase

iTREC software with optional GPS receiver• Provides continuous data coverage• Analyze data by travel time, speed/distance,

time/distance, stopped time, and number of stops.
