Chris, 

This solution is generally pretty reasonable as you have described it. So
long as there us priority leading up to the bottleneck, it is indeed the
best solution.  We use this solution quite a bit.  We know Volvo well.

I didn't work on this project directly, but if I understand it correctly,
one would open up the bus lane at the bottleneck so that the traffic is
always flowing out of the bottleneck at maximum capacity (so a 2 mixed + 1
BRT configuration would have an effective capacity of three lanes). The bus
would still have a huge advantage in heavily congested corridors because it
would effectively jump the longest queues leading up to the bottleneck and
would be inhibited by mixed traffic for only a short section of the busway
(like the queue formed by one cycle length). One could design it so that the
queue never expanded more than one cycle length at a signalized
intersection. Of course this traffic theory and technology leads to many
policy and implementation questions etc and it might be dangerous to concede
any bus right of way, especially in a difficult enforcement environment.
Also, as the bus lane becomes more saturated with buses, the effectiveness
of trying to use excess lane capacity dwindles. One note, Volvo is one of
the leading bus producers in the world and sells a lot of buses in China
under its joint venture Sunwin.

The papers from Berkeley make a few generalizations that are more typical of
conditions in the US than in developing countries. 

Segregated bus lanes will actually increase the speeds and capacity of the
mixed traffic lanes if the current traffic mix includes a large number of
buses with very disorganized stopping behavior.  This situation is typical
on many BRT corridors that ITDP is working on, all in developing countries,
but it is quite rare in the US.  

In conditions, as frequently occurs in the US, where bus frequencies and
passenger volumes are quite low, say below 5000 pphpd, and certainly below
2000pphpd, the advantages of physically segregated lanes drop if this leads
to congestion of mixed traffic, since a mixed traffic lane can move almost
as many people depending on the vehicle mix. 

This is a real issue in the US where the bus frequencies tend to be pretty
low due to low demand except on a few very exceptional corridors.  This
would be the case on Wiltshire Boulevard, for instance, and on a few major
arterials in New York, etc.  Probably a cost benefit analysis of converting
a mixed traffic lane to an exclusive bus lane would only yield a positive
result in higher demand corridors, and so harder to sell in the US.

Of course you can drop bus priority at bottlenecks, but you only need bus
priority at bottlenecks, so what is the point of the bus priority?  On many
brt systems we are planning there are parts of the brt network where we end
the physical segregation for a certain section.  Flyovers are the typical
situation.  However, we continue the segregation up to the bottleneck, so
the bus avoids the cue that sometimes forms to reach the bottleneck.  This
works fine.  But to open the brt up only at traffic bottlenecks sort of
defeats the purpose of the lane segregation otherwise, no?

In the developing world, this low bus frequency is not so typical.  In the
case of TransJakarta the lanes look empty at times in part because the bus
procurement has been held up, in part because demand is not that high yet
because there are very few feeder buses, and in part because the station/bus
interface in Corridor I, with only one door per bus on Corridor I, can't
really handle so many buses per hour.  Once these problems are resolved,
then the bus frequency will be much higher, and there will no longer be
empty lanes.  The justification for removing segregation will be weaker.
That being said, even a bus every 1.5 minutes looks pretty empty except at
the stations.  Stand on the road sometime and count a minute and a half
inside a lane, it seems like a long time. 

There are bus priority systems in Europe where there are bus priorty lanes
only at such bottlenecks, and they are cheaper to build but lack a system
identity. 

Hope this clarifies rather than confuses

Walter

I am very interested in this - does anyone think that this principle could 
be extended to optimizing the use of BRT rights of way to allow buses to 
enter and leave at various points without causing congestion?
