From page 33... ... Once the video clip has been assembled and calibrated, the cost per data point obtained is lower than that for traveler intercept surveys, but higher than for field laboratory studies. The cost per subject though is higher than for the traveler intercept surveys, because video labs typically test fewer subjects than would be found in an intercept survey. Read the entire page →

Thus a person watching 10 video clips generates 10 data points. Read the entire page →
From page 36... ... For example, efforts were made to identify sections of video in which the roadway width did not change during the drive or that the sidewalk conditions were relatively consistent. Using a portable mini-DV player, students identified the portions of roadway to be made into a clip based on criteria such as arterial type, consistent cross section, lane position, and speed limit.

From page 38... ... The bicycle LOS research methodology used was designed to achieve the following objectives: • Obtain bicyclists' perceptions of the level of accommodation provided by arterial roadways using a real-time fielddata collection event; • Coincident with the field data collection event, use video simulations to obtain bicyclists' perceptions of the level of accommodation provided by arterial roadways; • Develop an equation to correlate the video simulation responses to the real-time event responses; and • Provide the information necessary to develop the research team's initially proposed model form. For this NCHRP Project 3-70, a video simulation was used to collect data for the bicycle LOS model development. Read the entire page →

Given these advantages of video simulation, the project team used video simulation to collect data for the pedestrian LOS model. Read the entire page →
From page 40... ... Herman Huang, Ph.D., of Sprinkle Consulting, Inc., field-checked the Tampa locations and Dowling & Associates staff field-checked the San Francisco locations to verify their geometric and operational characteristics. Some runs involved unlikely combinations (for example, Run #11, which specified sidewalk width < 4ft and high pedestrian volumes) Read the entire page →
