EXECUTIVE SUMMARY
GREEN LINE TROLLEY SURVEY
EXECUTIVE SUMMARY
PURPOSE
This survey and report was prepared by San Diego Association of Governments (SANDAG) at the request of Metropolitan Transit System (MTS) to gauge the impact of the opening of the Green Line Trolley. Operations on the Green Line Trolley began in July 2005, and the Green Line Onboard Survey was conducted in October 2005, giving a chance for Green Line ridership to normalize and al- low students, especially ones attending San Diego State University (SDSU) to start regular use of the Green Line. This report documents the fi ndings of the Green Line Trolley Onboard Survey, developed by SANDAG, and the SDSU Transit Use Online Survey designed by MTS, as well as the SDSU Transit Center Count.
METHODOLOGY
The Green Line Trolley Survey was conducted via one-page written forms distributed on the Green Line Trolley over the course of four days in October 2005. Each trolley trip had one car surveyed, with all riders over 12 offered a survey, which was available in English and Spanish. Of an average October 2005 weekday ridership of 18,455 passengers, 3,495 surveys were returned and analyzed. The on- board survey had an estimated confi dence level of at least 95 percent, +/- 5 percent.
The SDSU Transit Use Survey was conducted via a web site, which was advertised in the SDSU e-mail newsletter sent to all students (about 35,000). Three hudred eighty-two students fi lled out the on- line survey. Because the survey was described as a Green Line Trolley Survey, very few non-transit users participated. In addition there were limited controls on how many times an individual could complete the survey and the respondents were self selected and not random. As a result, the online survey results are not considered representative of the student population, but do provide a general picture of SDSU students who use the Green Line.
KEY FINDINGS
The onboard survey shows that trolley users are most frequently making home-work trips (36% of trips) and home-school trips (30%). Old Town Transit Center and SDSU were the most common stations used, each accounting for one-fi fth of all boardings and alightings on the Green Line. Of people using the SDSU station, nearly 80 percent are going to the campus instead of the nearby com-

munity, and more than half of all SDSU station users are current students. One-third of Green Line users walk between their trip end and the trolley, while 42 percent use transit (either bus or trolley transfers) to connect between a trip end and the Green Line. Not surprisingly, trips ends going to home or coming from home had less walking and more automobile use, although more people use the bus to connect from home to the Green Line than actually drive a car. People who walked to/from the Green Line typically walked less than 10 minutes (nearly 90% of walking trips).
The opening of the Green Line has caused a mode shift for some travelers. Prior to the Green Line opening, one-quarter of current Green Line riders drove or rode in an automobile for their trip. This means that 4,600 trips have diverted to transit daily. 41 percent of respondents used transit service (bus or trolley) prior to the Green Line. More than half of riders who did not use transit a year ago now are using transit 5-7 days per week, with the most common fare media being monthly or college passes.
Green Line users have a positive impression of the new trolley vehicles, with higher marks going to the vehicle exterior than the interior and lower marks going to seat comfort. Most people are content with hours of service although 30 percent would like to see the service run later in the evening.
Online survey responses focused mostly on transit system users, most of which had used the Green Line and had favorable impressions of the system, again with car exterior being higher rated than interior. Two-thirds of students ride at least one day per week, with 30 percent riding everyday. A third of transit-riding students have used MTS bus routes during the current school year.
While the www.sdcommute.com web site was the most frequent way for Green Line users and SDSU transit riders to get information, Green Line Survey respondents were more likely to use the down- town Transit Store or1-800-Commute, while SDSU Online Survey respondents were more likely to use the www.sdsutrolley.org web site or the information center at Aztec Center.
SDSU RIDERSHIP ESTIMATION
The SDSU Transit Center Count showed that while bus use at SDSU Transit Center has decreased slightly, the opening of the Green Line Trolley has allowed for the total transit ridership to more than triple, from 2,200 weekday trips prior to the Green Line to more than 7,100 weekday trips in Novem- ber 2005.
CONCLUSIONS
The Green Line has been successful in attracting new ridership to transit. Forty percent of Green Line users did not use transit at all in the previous year, including the 25 percent who relied previously on automobiles. Existing transit riders who use the Green Line are becoming more frequent transit users. The SDSU Transit Center has generated nearly 4,900 new trips each day. This corresponds to about 2,000 cars no longer being driven to SDSU each day.
Approximately one-third of trips to/from the trolley are walk trips, therefore, MTS should encourage the improvement of the pedestrian environment within a ten minute walking distance of each on as well as encourage compatible land uses for more employment, housing, education, and shopping destinations within a ten minute walk of trolley stations.

While riders generally held a favorable view of the new cars used on the Green Line, impressions of seat comfort lagged by other aspects of the new cars. Changes to the design of the seats should be considered when additional new cars are ordered.
If additional hours of service were provided, more riders expressed a preference that service is ex- tended on Friday and Saturday nights.

CHAPTER ONE
GREEN LINE TROLLEY SURVEY
CHAPTER ONE: INTRODUCTION
GREEN LINE TROLLEY AND SDSU TRANSIT USE SURVEYS
This report documents the fi ndings of the Green Line Trolley Onboard Survey, conducted in October 2005 and the online SDSU Student Transit Use Survey, conducted in the fall of 2005.
Chapter 2 provides a detailed summary of the fi ndings of the Green Line Trolley survey, while Chapter 3 provides a similar analysis of the SDSU Transit Use survey. Chapter 4 shows the results of the SDSU Transit Center Count of boardings and alightings. Appendices A and B present the questions used for the Green Line Passenger Survey and the SDSU Online Survey respectively. Appendix C provides residence location information for survey respondents. Appendix D Contains Green Line station to station travel volumes from the passenger survey.
The 2005 Green Line Trolley Survey was conducted through onboard one-page written forms dis- tributed on the Green Line over the course of two weekday mornings and two weekday afternoons in October 2005. The survey was written by SANDAG staff and was made available in both English and Spanish. Copies of the survey in both languages are provided in Appendix A. Survey takers were instructed to offer the survey to all trolley riders except children under 12. It is estimated that ap- proximately 8,000 passengers were invited to complete the survey, and about 3,500 surveys were collected, with one car of every trip of the Green Line being covered once, allowing the survey distri- bution to correspond to one full weekday. The completed surveys were checked for reasonableness and then were coded for analysis. 3,495 surveys were considered valid for inclusion. The average daily ridership on a weekday for the Green Line in October 2005 was 18,455 according to the Passen- ger Counting Program. The confi dence level is estimated to be 95 percent with a potential margin of error of +/- 5 percent.
As a way to gain more information about transit users at SDSU, an online survey was conducted via surveymonkey.com, with the incentive of winning an iPod or other prizes to attract survey response. The survey questions were developed by MTS, with assistance from SANDAG. The survey was mar- keted via an article about the transit survey in the SDSU online newsletter sent to all students via email. The survey questions and online newsletter article are provided in Appendix B. Three hundred eighty-two SDSU students replied, with 90 percent of them having used an MTS bus or trolley dur- ing the current school year. Because of respondent self-selection, this percentage may or may not be indicative of the ridership behavior of the general student population, as non-riders may be less inclined to fi ll out a survey on transit use.

GREEN LINE TROLLEY SURVEY
CHAPTER TWO: 2005 GREEN LINE SURVEY RESULTS
The results of each question contained in the on-board passenger survey are graphically presented in this chapter.
Questions 1 and 4: Origins and Destinations
Q1: Where are you coming from?
Q4: Where are you going?
For each of these questions, respondents were asked to select one answer from six possibilities (home, work, school, shopping, recreation/visit friends, and other). The results of both questions have been combined and are displayed as trip ends in Figure 2.1. Origins and destinations are both considered trip ends. Personal Business was not offered as a choice on the survey but was mentioned by some respondents under Other, and so was recorded separately.

All other connections individually did not exceed one percent of valid survey responses. These results are consistent with the fi ndings of Figure 2.1, where Home as either origin or destination was nearly the sum of work, school and shopping.
Questions 2 and 5: Stations Used
Q2: At what station did you get on THIS trolley?
Q5: At what station will you get off THIS trolley?
This set of questions was answered validly on about 75 percent of all surveys. For the remainder, ei- ther respondents did not provide their boarding or alighting station information or their responses did not correspond to valid Green Line stations.

Old Town Transit Center comprised nearly a quarter of all boardings, followed by SDSU Transit Cen- ter. The next three most popular boarding locations are all major transit centers (Grossmont, El Ca- jon, Fashion Valley), served by many bus routes. Old Town Transit Center serves as the main transfer point between the Blue Line and the Green Line, while transfers between the Green Line and the Orange Line can occur at Gillespie Field, Arnele, El Cajon Transit Center, Amaya and Grossmont Tran- sit Center.
