DieselNet Spring 2006 mobility trace 

Bus-to-bus transfer record collected from DieselNet during the spring semester of 2006. The full trace description is available below.

Collection duration:
01/30/2006-06/22/2006

This trace includes two directories:
	* Bus-Bus subdirectory contains bus-to-bus transfer records
	* DispatchRecord subdirectory contains bus dispatching records.

1. Bus-to-bus transfer records are saved in files named as MDDYYYY, for example, file
2082006 contains transfer records for Feb 08, 2006. Within each file, each line 
describe a bus-to-bus transfer. For example, the following sample lines:

Bus 3112 at 72.532745 42.393852 on route 1 in contact with bus 3114 at 72.532745 42.393852 on route 1 at time 418:27 for 45204688 bytes in 184792.0 ms

means that the bus 3112 was in contact with bus 3114 while it's at location 
(72.532745 N,42.393852 W). The contact started at 418mins and 27 seconds after 
the 00:00:00 (i.e., 6:58:27 A.M.) of Feb 28, 2006, and lasts for 194792.0 
milliseconds. Note that the "on route 1" information should be ignored.

2. Dispathcing records include two files: DA_all.txt and DB_sheet.txt.

* The DA_all.txt contains the dispatching records (inputed by hand from 
the DA sheets, with drivers name ignored). 

For example, the following sample lines in the file:

6:30            AM43    42   NA      6:50         STKRD            9:05M 9:23T

6:40            AM31    16   NA      7:10         HAMPCOLL         10:45B/11:05G
6:42            AM11    33   NA      7:12         OLDBTOWN         10:51
6:45            AMA     21   NA      7:05         STADIUM          10:35
6:50            AM23    35   NA      7:10         HAGISMALL        10:00
6:52            AM1     36   NA      7:19         CLIFFSIDE        10:52
.....

Here, DATE line indicates the following records are for the date specified. Each line
follows give "TIME_AT_GARAGE  SHIFT   BUS  DRIVER  In_SERVICE   IN_SERVICE_LOC   DRVR_CHNG"
for each shift. For example, the line:

6:10            AM21    34   NA      6:55         MHC              10:30

means that bus 34 serve shift AM21 on that day, it starts at garage at 6:10 A.M.,
and starts to enter service at 6:55 A.M. at bus stop MHC. The bus will be changed to
another driver (also to another shift) at 10:30 A.M.

** DB_sheet.txt contains essentially similar information, dumped from a database system. 
Each line in the file specifies the mapping from bus to shift. For example,

03/01/2006,30,15MID,3033 

means that on March 1 2006, bus 3033 was dispatched to run on shift MID15, route 30.
