10 C h a p t e r 5 This chapter outlines the team's recommendations for elements to be included in proposals submitted in response to the S08 RFP. The work plan elements described reflect the key information needed to assess the merits of a particular research question or approach.

12 Roadway characteristics influence the safety consequences associated with changes of vehicle position on the roadway. A narrow lane or shoulder magnifies the safety consequences of a deviation from the center of the lane.

14 Random epochs provide random snapshots of the state of the driver and vehicle. Data samples might be collected every minute, every 5 minutes, or every hour.

16 five to six times as long as the actual video clip. For example, if a video clip of interest is 30 seconds long, it will usually take 150 to 180 seconds to manually code the clip.

17 In assessing the appropriate spatial technique, the proposal should explain the types of geospatial data that will be used and how these data will affect the segmented data that will be used in the analysis. Researchers should take care to recognize that some spatial data analysis techniques (e.g., T-squared sampling)

18 should also support interventions for roadway and vehicle design, as well as changes in driver behavior that might be induced through training, policy, or regulation. Identification and Justification of Analytical Approach The range of approaches to data sampling makes selecting the appropriate statistical technique a challenge.

19 Documentation of results and Data Warehousing This section describes the elements that should be addressed regarding documentation of the research results and data sharing between contractors and the data warehouse. Documentation of Research Results Proposers should outline the way research results will be reported to SHRP 2 according to the set guidelines for report formats.

20 that project outcomes directly contribute to enhancing driving safety. It is the understanding of the Project S02 team that S08 projects should result in outcomes that can be directly used by engineers and policy makers to guide decision making.
