were placed two feet inside the outside lane or buffer line and 30
feet apart. Paint was placed 30 feet apart, alternating every 15 feet to
create a two-foot path. Riders traveled in the middle of the two-foot
zone between the delineators and the lane line.

Data Collection
Test rides were executed when road conditions were consistent,
apart from one ride in wintery conditions. Rides took place between
3:00-5:30 p.m. to capture the evening rush hour when roads were
congested. The goal was to achieve approximately 400 passes (200
male and 200 female) on each bike facility. An approximately

one-half mile section of roadway was painted or delineated.
Researchers rode both sides of the ride segment in a circle until
a minimum number of passes (200) were obtained. Riders
staggered their starts so as to avoid any effects of riding in a group.
Researchers reviewed the video footage and documented the total
number of passes, the passing distance, whether there was a car in
the adjacent lane, and the vehicle type. If a passing car was more
than 99 inches from the cyclist, it was recorded as 100 inches since
the C3FT radar can measure a maximum distance of 99 inches.
This lowers the average VPD of the distribution to some degree and
changes the distribution of VPD at the tail.
