6.8.10 Bicycle Detection

When separate bicycle lanes are provided and bicycle detection is required, loop detectors with very sensitive loop arrangements spanning the whole width of the bicycle lane are necessary. An evaluation of inductive loops for bicycle detection has been reported by Leschinski (1994).

Where bicycle traffic shares lanes with other vehicles, it is not always possible to detect bicycles due to their small electromagnetic footprint. It might be appropriate in such cases to install other devices such as push-buttons to assist bicycle riders to lodge a demand or pavement markings to indicate the most bicycle-sensitive area of the detection zone, or, where bicycle volumes are low, do nothing.

To improve detection of bicycles, detectors can be marked to indicate the most bicycle-sensitive zone, as shown in Figure 6.17.
