Measure Results - Surveys

CTR-affected worksites must conduct a measure of employee commute behavior every two years to determine progress toward CTR goals. They are also required to conduct a baseline measure of employee commutes within 90 days of becoming affected by the CTR Law. The primary measurement tool is the state-provided CTR Employee Survey Questionnaire; it is available in two formats:

  • Online survey
  • Paper survey 

The survey measures employee commute behavior in two waysvehicle miles traveled per employee (VMT) and Non Drive Alone Trip (NDAT) for the employee population surveyed. In addition, the survey provides data on employee preferences for incentives and commute change, home zip codes and is useful in identifying areas for program improvement.

Training is offered regularly for the state provided survey process.
