Factors affecting pedestrian demand

The demand for pedestrian facilities is influenced by a number of factors of which some of the most important are :

1. The nature of the local community- Walking is more likely to occur in a community that has a high proportion of young people.
2. Land use: The type of land use in a particular area can affect the number of pedestrians. Areas with high-density residential, commercial, and entertainment land uses are more likely to have a higher pedestrian demand.
3. Car ownership -The availability of the private car reduces the amount of walking, even for short journey
4. Population density: Areas with high population density are more likely to have a higher pedestrian demand, as there are more people living, working, and traveling in these areas.
5. Quality of provision- If good quality pedestrian facilities are provided, then demand will tend to increase.
6. Accessibility: Pedestrian demand is influenced by the accessibility of destinations such as public transportation, schools, shopping centers, and other amenities.
7. Walkability: Walkability refers to the ease and comfort of walking in a particular area. Factors such as the presence of sidewalks, crosswalks, and pedestrian-friendly features like benches, lighting, and trees can encourage or discourage pedestrian demand.
8. Safety and security : Pedestrian demand is also influenced by the perceived or actual safety of an area. Factors such as traffic speeds, traffic volume, and the presence of traffic signals and signs can affect the safety of an area for pedestrians. It is important that pedestrians perceive the facilities to be safe and secure. For pedestrians this means freedom from conflict with motor vehicle, as well as a minimal threat from personal attack and the risk of tripping on uneven surfaces.
9. Weather: Weather conditions such as rain, snow, and extreme heat or cold can also affect pedestrian demand.
10. Age and physical ability: The age and physical ability of the population in a particular area can affect pedestrian demand. Areas with a high proportion of older adults or people with disabilities may have a higher demand for pedestrian infrastructure that accommodates their needs.
11. Cultural and social factors: Cultural and social factors such as preferences for walking or driving, lifestyle choices, and social norms can also affect pedestrian demand.

Effective walkway width

•Unlike vehicles, pedestrians don’t walk in organized lanes so lane concept is applicable to determine the number of pedestrians walking abreast in a given walkway width and the capacity of a stairway where the follow lane.

•In most cases, capacity of a pedestrian facility is directly related to the width of the capacity.

•The portion of pedestrian facility’s width used for pedestrian circulation is termed effective width.

•Although curbs and building walls have direct effect on effective width along the entire facility, single point obstructions like signs, hydrants affect its immediate vicinity. •Interference between two pedestrians can be avoided ensuring 2.5 ft (30 inch) of walkway width for each.

•Pedestrians occupy an average of 26 inch width each if the know each other

•Less than 26 inch lateral space indicates the most crowded situation.
