Graph
for determining appropriate cycling facilities (from CROW, 1993, p.80)
|
| Area 1 | All modes can be mixed. The only reason to consider bicycle tracks or bicycle lanes is for the sake of continuity of design on connecting bicycle routes. |
| Area 2 | This situation is merely theoretical. |
| Area 3 | In general a profile without segregation is acceptable, but depending on circumstances bicycle tracks or bicycle lanes can be desirable. |
| Area 4 | Some form of separation is needed , but visual separation (bicycle lanes) can be acceptable as well. |
| Area 5 | Bicycle tracks are desirable, but as densities are low, a mixed profile is acceptable. However, bicycle lanes are not advisable. |
| Area 6 | Speed and/or density of traffic flow make it an absolute necessity to segregate bicycles and motor traffic. Separate bicycle tracks are the only option. |
|
To see if a street is a candidate for a cycle track, see which area of the graph the street coordinates with. On the vertical axis, plot the traffic volume (average daily traffic, or ADT, measured in thousands of cars per day). On the horizontal axis, plot the 85th percentile speed (the speed at which 85% of cars travel below and 15% travel above). For estimating purposes, you can use the average speed (in km/ hour). For example, an arterial street with 9,000 cars a day and an average speed of 70 km/hr (42 mph), area 6 corresponds. |

Note:
Holland has the highest cycling rate in the Western Hemisphere. The mode
share for bicycles is 30% to 40% of all trips.
