Regarding the discussion with AC Transit about to deadhead bus -trips over the High Street
bridge, we have found a significant discrepancy in the data collected by their people and by us.
In our suggestion to AC to use Hegenberger rather than High Street for the trips between BFI
and their Division 4 facility, we had already observed that while the physical distance of the
Hegenberger route is larger, the actual transit time (as measured by us, driving the routes) is
about the same, and in some cases less than the High Street route (by about 2 minutes). We
asked AC to make the measurement themselves.
As we saw in the meeting at AC Transit on 22 March 2006 they did make the measurements.
We thank them for that and see that most of their conclusions match ours. However one result
was out of line with our measurements, and that result constitutes the vast majority of the
estimated costs ($12,648 of $18,972, or 67 %).
In addition to being out of line with our prior measurements, we see that there is a non - logical
time element in this particular trip description in the AC document....
The 5th trip , "Pull -out, Division 4 to Robert Davy Jr & Packet
Landing" and the 6th trip , "Pull -out, Division 4 to Bayfair" differ
in their route by only the last leg of Island Drive to Packet
Landing. This applies to both the existing route and the proposed
alternate route.
To be clear, for both the 5th and the 6th trips, the ONLY
difference is in the last leg, which while different for the two
trips, is NOT DIFFERENT between the existing route and the
alternate route.
However, the AC document shows a 1 minute delta in trip time
for the 6th trip and a 4 minute delta in trip time for the 5th trip.
We think that one of these two measurements is wrong, or possibly there is another variable that
is not shown in the AC document. We wondered if possibly the issue was time of day, and asked
Sean Diest Lorgion, the AC man who presented the measurements. He said that the
measurements were made at rush hours, 8 AM and 5 PM.
As our previous measurements were made at noon -time, we re -drove the routes at 5 PM. The
noon -time drives showed that the alternate route for trip 5 was actually slightly less than the
original route. The evening drives showed the delta time between the original and alternate
routes to be 1 minute.
Giving AC the benefit of the doubt, and calling the delta 1 minute rather than zero (for just this
one trip), reduces the estimated cost from $18,972 to $9,486. Note that this reduction applies to
just this one trip, and further cost reductions might arise with the careful examination of the other
trips.
Additionally, on one of our 2 drives over the High Street route, we lost a little over 2 minutes
waiting while the train blocked the path (we subtracted that lost time from the overall route

timing to maintain validity). The alternate route does not have this or either of the two bridge
crossings as statistical additions to the length of the trip.
While we appreciate that AC did take the time to make the measurements, this large apparent
discrepancy in the most significant trip of the batch causes us to want to re- examine their entire
analysis.
It is not our intention to embarrass AC, we just want reasonable decisions that are based on the
true data.
