105 APPENDIX B Study Protocol PROTOCOL: 1. There are no direct benefits to the participants. The study is likely to yield general information about driver perception of quality of service of roadways. We will use the drivers' appraisal of streets as depicted on video clips to understand driver per- ception. Currently, there is no recognized methodology that measures the quality of service provided by transportation facilities from the drivers' perspective. We will recruit participants in four representative locations in the US through per- sonal contact and limited advertising. 2. We will ask participants to read and sign an informed consent sheet (a representative copy is attached, which will be replaced by the approved informed consent form when approved by the HSRB). Participants who elect to be paid will receive a $75 cash payment upon completion of the study. Participants will be paid through the grant. Payment is required to compensate for the inconvenience and time required to participate in the study. Student participants will receive course credit. 3. No minors will be involved. Participants will be at least 18 years of age. 4. Participants will view a series of video clips using a large screen projection system and an LCD projector. The test will be con- ducted in two parts. In part 1 of the study travelers will be prompted to rate their overall level of satisfaction with the facility on an A-F scale. After viewing all of the clips (total viewing time less than 120 minutes with 2-3 10 minute breaks) part 2 of the study will begin. Part 2 of the study is a focus group that will involve a portion (6-7 participants) of the participants. The purpose of part 2 is to learn more about specific features or conditions that relate to driver ratings of performance as por- trayed in the video clips. 5. Each subject will be assigned a unique ID number. However, the information connecting a person's ID to their name will be stored in a separate file until data collection for that subject is completed. At that time, person-identifiable information will be discarded, as it will no longer be needed. Thus, no person-identifiable data will be maintained once data collection has been completed. 6. This research poses no more risk than that which would ordinarily be encountered in daily life. The expected benefit of this research is an increase of knowledge about the factors underlying driver satisfaction with the quality of service on urban arterials. 7. The rating forms will be secured at the George Mason University Department of Civil, Environmental, and Infrastructure Engineering (identified by subject id number and date), and will not be shown to individuals or agencies outside of the research team. The forms will be stored in a secure, locked private office and labeled by subject number, date and location. Participants' names will not be written on the forms. The data on the forms will be entered on a computer spreadsheet, but subjects' names will not be entered in the spreadsheet. 8. There is no need to misinform, or to not inform subjects about the true nature of the project. Informed Consent Form The purpose of this project is to obtain driver opinion about roadway conditions and features in a multimodal environment. In the study, you will be asked to watch several video clips. Upon the completion of each video clip, you will be given the oppor- tunity to write down your rating of the clip. Once you are finished rating a clip, the next clip will be shown and the process will

106 be repeated. After about one hour, we will take a break and questions will be entertained. After the break, we will resume watch- ing clips and you will rate the clips. The project can benefit drivers indirectly by helping traffic engineers further understand the features and factors on roadways that are important to the driving public. There are no direct benefits to you; however, the proj- ect may help traffic engineers further understand the features and factors on roadways that are important to the driving public. The entire sessions should not last longer than three hours. Upon completion of the clip ratings, you will be asked to turn in your rating sheets. We will then provide you with an honorarium. At that time, we will answer any questions you may have about the project. Please note the following: Your participation is voluntary. You may discontinue participation at any time without penalty or loss of benefits to which you are otherwise entitled. You will be provided with a $75 honorarium in recognition of the value of your contribution to the study. All data collected in this study are confidential. All surveys will be discarded after the data analysis. This study is being directed by Aimee Flannery of the Civil, Environmental, and Infrastructure Engineering Department at George Mason University. Dr. Flannery may be contacted by email at aflanner@gmu.edu or at 703-993-1738 should any question arise.

108 ABSTRACT: The abstract must appear here. Use a separate sheet for continuation. Refer to the guidelines on the reverse side.4 The project's goal is to obtain driver opinions and perceptions of the quality of service on urban streets, defined here as signalized, multi-lane highways with cross-streets placed to 1 mile apart. Drivers' perceptions of service can be useful to traffic engineers in the design and improvement of roadways and can be used to supplement the Highway Capacity Manual. The information obtained in the project will provide the academic and practitioner with a better understanding of driver perceptions about roadway quality of service. The project proposes to ask licensed drivers to view video taped segments of urban streets and rate the quality of service on the streets presented on the video. The drivers will complete a short rating form for each segment shown. The video tapes will be projected on a large screen in a classroom setting. Approximately 140 drivers are required for this project. The subjects will be licensed drivers aged 18-65 years of age. The criterion for inclusion for the subjects is a valid driver's license and willingness to participate in the study. Drivers will be paid for their participation or receive class credit. The proposed research will involve the following (check all that apply): VULNERABLE POPULATION: PERSON IDENTIFIABLE DATA: RESEARCH DESIGN: __Fetuses/Abortuses/Embryos __ Audio taping __ Questions on harm to self or __Pregnant women __ Video taping others __Prisoners __ Data collected via email __ Questions on illegal behavior __Minors __ Data collected via internet __ Deception __Mentally retarded/disabled __ Confidential electronic records __ Human/computer interaction __Emotionally disabled __ Coded data linked to individuals __ Collection and/or analysis of __Physically disabled __ Human biological materials secondary data __Psychology undergrad pool OUTSIDE FUNDING: __Other: Source ____Transportation Research Board____________________________ Revised March 2005 ABSTRACT 1.
