segment is collected. In this case the segment length will be the distance traveled in feet. The equation
for PRI is:
𝑃𝑅𝐼 =
𝐶𝑜𝑢𝑛𝑡𝑠 𝑓𝑜𝑟 𝑅𝑜𝑢𝑔ℎ𝑛𝑒𝑠𝑠 𝑖𝑛 𝑖𝑛𝑐ℎ𝑒𝑠 × 5280
𝐷𝑖𝑠𝑡𝑎𝑛𝑐𝑒 𝑇𝑟𝑎𝑣𝑒𝑙𝑒𝑑 𝑖𝑛 𝐹𝑒𝑒𝑡
Point Events
Point events, also known as notes, are items or features at specific locations that the user wants to
store and identify within the data. Point notes can also be used to identify sections of the sidewalk
that do not meet specifications through the height or width requirements.
Segment Events
Segment events, also known as intervals, are interruptions or important structures that occupy
intervals of the sidewalk. Segment events include crosswalks, driveways, sections without sidewalks,
curb ramps, bus stops, and pauses which are related to the profile.
Odometer
The odometer can be found in two places within the SSI Profiler program, both under the collection
window. The initial odometer is on the home screen of the collection window. This odometer will be
in the form of a separate window. The second odometer aids the user in adding and editing events
after a collection is ended.
Pause
A pause is a section of the profile that can be excluded from the report or specifically viewed to
determine its profile ride number (IRI, PRI, etc.)
Profile Collection
When a data collection begins, the profiler will collect the profile of the sidewalk. Once the profile
collection is started, events can be entered in the form of point or segment events.
Interval Collection
An interval collection is the process of adding a segment event to the collection. To add a segment
event, select the ‘Start Interval’ icon during a collection. After t he collection the user will be able to
apply a type of segment event and edit the stationing before saving the collection.
Sidewalk Profiler Hardware
Switches
The profiler has two switches located on the top of the electronics housing. One switch is for the
power of the profiler while the second switch is used to turn on the lights. When the profiler is turned
on, the battery meter will illuminate. The lights will only work if the profiler is turned on or charging.
Laser
The laser mounts to the front of the profiler body and is connected to the electronics via two cables.
Ensure there are no obstructions between the laser and the ground. When powered on and
connected to the electronics
the “POWER” and “LASER” LEDs will illuminate though the “RANGE” LED
and beam on the ground will only be visible when collecting data.
