Pedestrian and Cyclist
A Pedestrian is a person travelling on foot, whether walking or running and a Cyclist is someone who rides a bicycle or is riding a bicycle.

Methods of Pedestrian Data Collection
Manual Counts
Automatic Counts
Videographic Survey

Pedestrian Flow
The dimensionality of pedestrian infrastructure facilities have a great influence on pedestrian movements and a considerable impact on the natural environment of the facility.
Understanding the Pedestrian movements are crucial to estimate the capacity of the system accurately, especially in the transportation terminals such as railway stations, bus terminals, airports and so forth, where large crowds gather and transfers.
To have a safe and comfortable movement in a normal situation and also a quick evacuation in an emergency situation, pedestrian movement patterns should be analyzed and modelled properly.
Pedestrian Flow characteristics constitute one of the foundations of urban traffic planning and this includes analyzing walking speed, flow, density, and space required by the pedestrians.

Pedestrian Facilities
Sidewalk/Footpath
Crosswalk
Stairway
Foot Over Bridges/Skywalk
Pedestrian Level of Service
Pedestrian Level of Service (PLOS) is a qualitative measure used to relate the quality of pedestrian service and it represents the quality of given intersection in terms of perceived safety, convenience, and comfort in terms of pedestrian perspective.
PLOS is an important measure of performance in the analysis of existing pedestrian crosswalk conditions.
