71:. There are two parallel stop lines at the intersection, the first one at which all traffic except that for which the facility is provided must stop, and a second one nearer the intersection to which only specified vehicles may proceed. If the signals change to red when a vehicle is crossing the first line, the driver must stop at the second line The area between the stop lines is the "reservoir" or "box". Signage may be required to inform road users as to the meaning of the extra stop line. A separate set of traffic signals may be provided for the specified traffic, but all vehicles usually use the same signals.

four signalized junctions, where the stop line for motorists was recessed by five metres.... In the before period, between 12 and 24 per cent of the drivers turned right straight in front of a cyclist. In the after period, only 3 to 6 per cent did. On the basis of these results, safety of cyclists could be expected to improve. TRL in
England (Wheeler, 1992) studied advanced stop lines (ASL) for cyclists at signalized junctions. ... The number of cyclists having a good position before turning right went from 57 per cent to 97 per cent.

Consortium showed that motorists and cyclists alike appear to understand and comply with the boxes. Nearly three quarters of motorists stopped behind the bike box and roughly the same percentage of cyclists stopped at the proper location ahead of the motor vehicle stop bar. In addition, the number of conflicts at the intersections decreased and drivers yielded more to cyclists after the boxes were installed. User perceptions of safety also improved.

If the signal is green, cyclists are advised that the best way to minimize danger may be to stay within the main traffic stream. If the lights change while the cyclist is still approaching, the advice is to negotiate their way back into the main traffic stream if possible. Advice produced by the

the main traffic stream. An ASL will also help reduce the exposure of such cyclists at junctions with nearside (i.e. left in the UK and
Ireland, right in USA, etc.) filter lights by providing a place for cyclists to wait while traffic passes on the inside. A similar consideration arises where a free turn to the nearside is permitted (called

In the
Swedish study mentioned earlier (Linderholm, 1992) ... analysis of the before-after situation showed that a recessed stop line for motor vehicles reduced the accident risk for cyclists crossing by about 35 per cent. ... In Denmark, the Danish Road Administration (1994d) carried out a study at

they have been used on the approach to a signalised roundabout. Success will depend on motorists not blocking the cycle lane or encroaching on the reservoir, and on signal timings which ensure that cyclists are not frequently

At a red light, cyclists are more visible to motorists by being in front of them. At a green light, the painted bike lane and bike box through the intersection reminds motorists and cyclists to watch for each other.
