Flexibility of Survey Design

Redhill Group’s proprietary CATI system has been custom-designed to meet the most demanding requirements of sophisticated transportation research. The flow of questions and responses is completely unconstrained, allowing survey design to follow any pattern desired.

Some of the specific capabilities include:

  1. Automatic or random order rotation of both responses and questions to eliminate response-order bias.
  2. Real-time calculations based on a combination of respondent answers and client provided formulas. The result can then be inserted into a pre-determined follow-up question.
  3. The ability to automatically track multiple responses and ask follow-up questions pertaining to each of those responses.
  4. The ability to automatically track callbacks that respondents might request in order to complete the survey at a more convenient time, thereby improving the response rate.
