Pedestrian LOS (Fruin) is an overall measure of walking conditions on a route, path, or facility. This is linked directly to factors that affect congestion, comfort, and safety, reflecting pedestrians' perceptions of the degree to which the facility is 'pedestrian friendly'. LOS is graded from "A" through "F", with "A" generally representing the most favourable conditions and "F" representing the least favourable. An LOS of A or B is generally accepted as representing favourable walking conditions.

 Table 3.4.11.1 Minimum Width of Footways from TDPM

Land Use Type(1)	Through Zone Width / Peak Pedestrian Volume	Street Furniture and	Building Frontage
	(Pedestrians per minute)	Greening	Zone Width
		Zone Width
Commercial	4.5m	1.5m(2)-(4)	0.5m for dead areas and increase to 1m for shopping frontages
Commercial / Residential	Very High (Over 100)
Residential Zone 1 and
those other areas near
pedestrian generators
such as cinemas, rail
stations, some GIC
facilities (e.g. schools), etc
Residential Zone 1	3.5m
	High (80-100)
Residential Zone 2	2.75m
	Medium (60-80)
Residential Zone 3	2.0m
	Low (Below 60)
Rural	2.0m
	Very Low
Business	4.5m
	Medium (80)
General Industrial Use	4.5m	4m(3)-(4)
	Medium
Special Industrial Use	3.5m	2m(2)-(4)
	Low to Medium
Rural Based Industrial Use	2.5m	1.5m(2)-(4)
	Low

NOTES :	(1)	For classification of land use, please refer to the HKPSG.
	(2)	The SF&GZ width should be increased to 3m for planting of large trees or understorey planting along boulevards or main roads. The boulevard or main road should have one or more of the following characteristics :  - as major transport and pedestrian corridors in a district  - clustering with major community and tourist attractions  - developing with line of high-grade offices, retail and hotel developments  - as important district retail street  - a road of wide scale (e.g. dual 2 or 3 lane carriageway)
	(3)	If a bus shelter exceeding 1m width is provided along the footpath corridor, additional width should be suitably allowed in the SF&GZ.
	(4)	When street furniture exceeding normal object width of 1m (such as artwork) is required, the SF&GZ would need to be widened to cater for its provision.

TDPM cl. 2.6.3.1 Where bus shelters are provided, appropriate clearances must be maintained for general pedestrian traffic on footways. Table 3.4.11.1 of Volume 2 is repeated below which gives some basic guidance. Where there are land constraints some reduction of these values may be acceptable rather than not providing a shelter at all, to a maximum of 75% of the values shown in table 3.4.11.1.
