Extended Cycle Feeder Lanes

Always useless? In fact this typical Advanced Stop Line in the City is worse than totally useless. The feeder cycle lane starts less than a car length from the bike box so you can't actually get into the bike box (DfT guidance is for feeder lanes to be long enough to get you past queuing traffic). It's so narrow that a cycle is too wide to fit in it and a car is too narrow to fit in the rest of the lane. This type of incompetent design increases the risks to cyclists dramatically as it encourages them into the gutter and large vehicles' blindspots: the majority of City cycle fatalities involve large vehicles turning at junctions.

Best practice for left turn lane - motorists are made to feel they have to give way to cycles proceeding straight ahead and the conflict area is highlighted by the coloured surfacing.

Cycle lane protecting straight ahead cyclists while providing a left filter lane. It would be better if the cycle lane existed on the side of the road further back from the junction.

Left turn (on pavement) cycle feeder lane combined with straight on cycle lane in limimted space. Note the special sign for a cycle lane in the middle of the road. This requires special authorisation from the DfT as it is not an official sign.

ASLs with feeder lane for straight on and right turns. Note the special sign for cycle lanes in the middle of the road beneath the parking sign.

While not perfect - there are no feeder cycle lanes - these ASLs shows how cycles travelling in different directions can be split and specifically arrows marked in the ASL to make this clear.

Motorbike ASLs

The UK's first ASLs for motorbikes are in the London Borough of Newham, also on a main cycle route. Why though is the cycle symbol in the gutter of the bus lane? Many cyclists are against allowing motorcycles into bus lanes for the following reasons:

Motorcycles spew out more pollution than any other vehicle type - not what pedal cyclists want to have to breathe in. Pollution masks are particularly unpleasant for cyclists as they are difficult to breathe through when exerting oneself.
They can accelerate faster than any other vehicle - which helps make them cause more crashes than all other types of vehicle. It is crazy to mix them with pedal cycles which accelerate slowly and need space as they move off when they are least balanced at slow speeds.
They are intimidating for pedestrians using the crossing and for pedal cycles waiting at the signals.
Motorcycles are not that space efficient which is the main justification for giving vehiclesan advantage at traffic signals. A car with three people is a better use of space. They are much less space efficient than cycles as space use is a function of size and speed (that's why the M25 lowers its variable speed limit during times of congestion).

A happy motorcyclist waits ahead of the traffic - note the mandatory feeder lane coloured blue to the left. Motorcycles should not be allowed in bike boxes as:

The same ASL from the rear. There is no pedal cycle feeder lane at all despite there being three general traffic lanes, one of which is a left turn lane. Those using the cycle route will have to weave dangerously through the traffic to avoid being knocked over by left turning traffic.

At another arm of the junction there is at least a pedal cycle feeder lane but it's narrower than the motorcycle lane and is only advisory not mandatory. Still the cars seem to ignore both!
