The limiting factor in common with all of these approaches is that the bicycle thief can approach the bicycle without being challenged by members of the public, seriously or at all. This is shown in the footage in the following footage:
This is an experiment that has been done many times, by different groups of people, each time with the same result. Parking a bicycle in a public area is good advice, but will not prevent a determined thief.
The old doctrine of 'predict and provide' for road building has been dropped in the UK, but the baby has indeed been thrown out with the bathwater. Predict and provide can indeed increase the number of times that journeys are made, but whereas there is an argument for controlling the number of car trips by rejecting this approach, the government is formally committed to increasing the proportion of cycling. Predict and provide is therefore the correct approach for cycling, and the failure to predict and provide leads to a shortfall in cycle parking, as shown in Figure 4.

One unfortunate cultural attitude, which is apparent even within Transport for London, is the idea that it is possible to park two bicycles [p8-9] on one Sheffield Stand. Some cyclists, with well-weathered bicycles may not object, but cyclists with nice new bicycles certainly would.
One approach is represented by the secure bicycle parking in Leicester, as is shown in Figure 5. This facility is called 'Leicester Bike Park'. This cycling facility, provided by Leicester City Council, in conjunction with Environ and Webster Cycles cycle shop, provides 120 parking spaces. The cycle shop means that customers can leave their bicycles at the facility for repair whilst they go about their business. Cyclists are charged to use the facility, which is unusual, since in most cases it is expected that cycling facilities will be provided free of charge. That it is well used suggests that many cyclists would be prepared to pay a charge to use a facility which is of good quality.
