Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

108 Installation History at Each Study Center The following tables present installation-related information for each of the six study centers by year and month of the pro- gram. It is important to note that there were no formal require- ments for the collection of most of the data in the tables. With that in mind, each center established its own process for the col- lection of the data and not all of the data are available from all of the study centers. That said, each of the tables in the appendix contains columns with the following information: Year and Month—Self explanatory Appointments Scheduled—The number of all installation- related appointments scheduled during the subject month. Ideally this number should include appointments in which participants arrived and had successful DAS equipment installations performed, appointments in which the par- ticipant was a no-show or cancelled, and appointments in which participants arrived and had their vehicle rejected for installation. # Installed—Number of installations performed. Ideally this should include DAS equipment installations into the vehi- cles of new participants as well as reinstallation of equip- ment into the vehicles of existing participants. The latter event occurred most often when an existing participant acquired a new car and wished to continue to be a part of the program. Number of Cancellations & No-Shows—Number of times a potential participant cancelled a previously estab- lished installation appointment or did not show up for an appointment. Number of Vehicles Rejected at Site—Number of times potential participants showed up for an installation appointment but had their vehicle rejected for installation. % of Cancellations & No-Shows (Month)—Percentage of all appointments made for installations during the sub- ject month that resulted in cancellations or potential par- ticipant no-shows. % of Appointments with Vehicles Rejected—Percentage of all appointments made for installations during the sub- ject month that resulted in the rejection of the potential vehicle. % of Cancellations & No-Shows (Program to Date)— Cumulative percentage of appointments made for instal- lations that resulted in program-to-date cancellations or potential participant no-shows.

TRB’s second Strategic Highway Research Program (SHRP 2) Report S2-S07-RW-1: Naturalistic Driving Study: Field Data Collection that summarizes the compilation of a comprehensive naturalistic driving database. This database, together with associated roadway, driver, and environmental data provides a resource from which to study the role of driver performance and behavior in traffic safety and how driver behavior affects the risk of crashes.

The Naturalistic Driving Study was tested in several locations with In-Vehicle Driving Behavior Field Studies, including:
