Your CTR survey

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: The survey measures employee commute behavior in two ways: vehicle miles traveled per employee (VMT) and single-occupant vehicle rate (SOV) 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. Employers are also allowed to use pre-approved equivalent data instead of the survey.

Foreign Language Translation Guides are available for use with either survey format as needed.

The State Guide to Employee Surveys (PDF) can provide answers to most technical survey questions. Highlights listed below:
