Step 5 – Design Appropriate Measures

Once appropriate measures conforming to a city’s cycle policy have been selected, they should be designed appropriately. Most cities worldwide tend to adopt and develop their own detailed design guidelines, however the following section provides guidance on the basic design of common measures and can be used as advisory design notes.

NMV Lanes

NMV lanes can generally be classified into four main categories as listed below.

Table 4 Types of NMV Lane

Type Cross Section

Type I NMV Lane

NMV lanes shared with MVs and designated by signs

Type II NMV Lane

NMV lanes designated by lane markings (e.g. striping) and within the highway right-of-way

Type III NMV Lane

NMV-exclusive lanes physically separated from MVs by barriers (e.g. concrete blocks, steel railing, raised curb) and within the highway right-of-way

Type IV NMV Lane

NMV-exclusive lanes within an independent right-of-way (often referred to as NMV paths)

Minimum recommended widths for bicycle lanes vary from country to country, however they typically fall within the range of 1.2–2.0 metres, which allows for the physical width of a bicycle’s handlebar plus a margin of safety. For different NMV types, recommended lane widths are provided in Table 5.

Table 5 Recommended NMV Lane Width

NMV Type Type II Lane Type III & IV Lanes Increment Increase
Minimum Standard Minimum Standard Minimum Standard
Bicycles 1.2 1.4 1.5 1.5 1.0 1.0
Cycle-Rickshaws 1.8 2.3 2.3 2.5 1.5 1.7
Animal Carts 2.0 2.4 2.5 2.7 1.7 1.8

Note: These NMV lanes are considered to operate as one-way facilities

In cities with high use of one or more NMV types, these lanes should be widened to provide sufficient capacity. The recommended increment to increase the width of the facility is also provided in the Table.

The recommended maximum gradient of NMV lanes should be no greater than 5%. This is the maximum slope that would still allow safe downhill speeds and reasonable climbing effort for NMV operators.

If Type II, III, or IV NMV lanes are to be provided, a certain percentage of expected (or observed) NMV traffic volume during the peak hour should be used to determine the number of NMV lanes that would be required to meet demand. An indication of volume/hour that could be accommodated by type of lane is shown in Table 6.

Table 6 Maximum NMV Demand by Type of NMV Lane

Type II Types III & IV
Bicycles 1,210 2,070
Cycle-Rickshaws 640 1,120
Animal Carts 310 570

Note: These NMV lanes are considered to operate as one-way facilities
