Survey

Introduction

This survey was conducted through the Lighting Transformations Program of the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute and was supported by the Pacific Gas and Electric (PG&E) Company. Gary Fernstrom, PG&E Project Manager oversaw the survey and provided valuable input on the survey questionnaire used. Noel Simpson and Andrew Johnson of the LRC interviewed the survey participants during November and December 1998. John Bullough and Kathryn Conway summarized the survey results.

Purpose

The primary purpose of this telephone survey was to generate information that could be used to develop a "snapshot" of existing and potential markets for light-emitting diode (LED) traffic signals in California. In particular, information about factors that act as barriers to more widespread use of LED signals, as well as those that act to facilitate the use of LEDs was gathered.

Method

A telephone survey consisting of 17 questions was developed. A copy of the survey is included among the links below. Individuals from 31 municipalities in the state of California participated in the telephone survey. Each interview took approximately 20 minutes.
