Version 1.5.4

Version 1.5.4• Analyst Drive 1.5.4 uses a 64-bit compatible code. It can handle

large networks and complex optimization problems since it does not have restrictions on memory usage.

• Updated system error code reporting.

• Added FILE_ERROR=203 - Registry key not found.

• Added FILE_ERROR=124 - No non-zero screen line values in the screen line file.

• Added FILE_ERROR=107 - Can't read PKTLNG value from packet log file.

• Added FILE_ERROR=29 - Error reading trip end file.

• Added FILE_ERROR=25 - Error reading the input warm start turn choice matrix.

• Added FILE_ERROR=26 - Insufficient memory to use MEMOPT2=T option. The user should set MEMOPT2=F and try the estimation again.

• New options MEMOPT1 and MEMOPT2 which tells the program to use a new all memory version of the packet log file processor and also uses the bucket sort subroutine which has been disabled as it requires a substantial amount of memory. MEMOPT1 option requires the user to have at least 12*NPKT(PKTLNG+2) bytes of available memory, NPKT and PKTLNG are defined in the packet log file header. MEMOPT2 requires 12*I*J*D*K*T bytes of memory.

• Fixed an error in the file based packet log processor which incorrectly processed certain packets to indicate they matched a turn count set. If the last traversal line of a packet contained the first two nodes of the turn it was included even though it did not complete the turn with the third node because there was no subsequent line to process.

• Updates to wording of cost reporting after the final iteration to avoid confusion in interpreting print file.

Version 1.5.4

• New MPIWILD parameter - allows user to define the root drive for when running MPI on distributed cluster. Allows the use of a wildcard character in the drive name.

• Updated to use 8 byte integers for some internal variables in all subroutines. This is necessary for dealing with large ICP files exceeding the 4 byte integer number of entries.

• Added MPICTLF parameter, this allows the user to specify a separate directory for the control file if using MPIWILD and the control file is not located on the same drive as the Cube installation.

• Bug Fix for running multiclass static estimation with the options CONFMAT=T and USECONF=F. This combination failed to iterate through classes when building input matrix files causing the first file to be rewritten for each class and hence the successive class matrices were left empty.

• Fixed a bug occurring when performing static multiclass estimation with MPI. In this case it was possible for master process to attempt to write the final output matrix before one (or more) of the slave processes was finished converting an individual text output matrix to Cube format, causing the master process to throw FILE_ERROR=194 illegal storage access.

• Full partial trip dynamic estimation capabilities for using Bluetooth and other detector/survey data. The resource file has been updated to make room for the addition of partial trip data files thus altering the max number of classes that can be estimated due to the 80 file limit imposed by the resource file. The number of input static files was reduced to make room for more dynamic files, previous limits were Static=20 and Dynamic=8, new limits are Static=15 and Dynamic=10.

• The CONTCONF option has been updated to be set to true by default.

• Added an option MPILOCAL. If MPILOCAL is set to true the setup program will add the MPI command line option -local root to the mpiexec call. This suppresses the password requirement on

Version 1.5.4

a local machine when launching more than one process (e.g. MPICORES > 1) but will still require a password on the first use when running on a distributed memory system.

• Fixed a bug in the gradient calculation procedure.

• Fixed a bug related to dynamic turn counts.

• Updated to use the high screen line number from the screen line file instead of the ICP file.

• Updated the report file to more accurately describe results based on what is happening in the dynamic estimation process by reporting results based on adjusted observed counts rather than adjusted simulated volumes when doing warm start estimation.

• Fix for TPWGHTI parameter where the incorrect values are passed to the program.

• Fix for MATWGHT parameter where the incorrect values are passed to the program.

• Fixed error in cost function evaluation which always used the scaled version for the background term contribution during static estimation... this has been fixed to use the appropriate scaled or unscaled depending on the program option. This fix could lead to solution changes from previous versions in all static estimation problems.

• Fixed a bug in multiclass estimation where updating the count vectors for zero proportion screen line values could lead to overwriting the end of some temp vectors when calculating multiclass sums which lead to the program crashing.

• Added "Final" cost and RMSE after "Last Iteration" cost and RMSE in the print file for clarification.

• Added statements to the print file for static estimation describing the trip end and background term contributions to the cost function in order to provide the user with a sense of scale when selecting the weighting parameters.

Version 1.5.4

• Fixed an error present when using both turning counts and screen line counts simultaneously in dynamic estimation. In this case, after processing the packet file to produce the screen line route choice matrix the program was double counting OD totals when it next went to process the turn route choice matrix. This caused the turn choice matrix values to be half of their correct values.

• Updated parallelization scheme for dynamic estimation for bigger optimization problems. This should lead to substantial speed up for large problems using more than 3 cores.

Version 1.3.1

Version 1.3.1Fixed a bug present in aggregate static estimation where a misalignment of data occurred in the presence of zero proportion screenlines for multiple consecutive user classes when the last zero proportion screenline number for a particular class was less than the first zero proportion screenline of the class which immediately followed it.

Version 1.1.15

Version 1.1.15Fixed a bug occurring when performing static multiclass estimation with MPI. In this case it was possible for process 0 to attempt to write the final output matrix before one (or more) of the slave processes was finished converting an individual text output matrix to Cube format. This caused the master process to throw FILE ERROR=194 for illegal storage access.

Version 1.1.14

Version 1.1.14Bug Fix for running multiclass static estimation with the options CONFMAT=T and USECONF=F. The code section for this option combination failed to iterate through classes when building input matrix files causing the first file to be rewritten for each class and hence the successive class matrices were left empty.

Page 18: Cube Analyst Drive - Amazon Web Servicescitilabs-website-resources.s3.amazonaws.com/... · 14 Cube Analyst Drive Release Summary Version 1.1.14 Version 1.1.14 Bug Fix for running

Version 1.1.0

Version 1.1.0Two typos were found in the resource file, first the TRWGHTI was incorrectly spelled TPWGHTI so if the user ever set this parameter it was never actually passed through to the program, if this parameter is used now the user may see a di?erent solution. Second, the MATWGHT parameters default value was listed incorrectly in the resource file, it should be 0.1 and not 1. Users will see no change in their solutions, but may notice odd behavior if experimenting with the MATWGHT parameter in the old version since entering 0.1 will give the same solution as the perceived default of 1, and e.g. 1.0000000001 may give a much di?erent solution depending on the problem. This version includes several other bug fixes 1) TRWGHT values were being incorrectly passed as 1, and not the default of 100. 2) It was discovered that he gradient contribution from the trip end data was commented out in the code during testing some time ago and never uncommented... this has been corrected. From 1) and 2), users estimating with trip end data may see di?erences in their estimated solutions with the new version. 3) Fixed error in cost function evaluation which always used the scaled version for the background term contribution during static estimation... this has been fixed to use the appropriate scaled or unscaled depending on the program option. This fix could lead to solution changes from previous versions IN ALL static estimation problems. 4) Fixed a bug in multiclass estimation where updating the count vectors for zero proportion screenline values could lead to overwriting the end of some temp vectors when calculating multiclass sums which lead to the program crashing.

Version 1.0.12

Version 1.0.12Fixed a bug which appeared when using turncounts and screencounts simultaneously AND when needing to reshape arrays to account for zero proportion screenline values. In this case the turncounts array was allocated an incorrectly sized chunk of memory that could cause other arrays to be overwritten. Also fixed a bug where the memopt button was causing crashes in Task Manager, memopt button is essentially ignored now.

Version 1.0.11

Version 1.0.11Fixed a bug related to dynamic turncounts. In certain cases where AD needed to reshape the turncount array to properly align the input data for sparse matrix calculations, the allocation size was incorrectly set to use the screencount size which might have caused errors that could have gone unnoticed, but depending on the situation may or may not have affected the solution. In the case that the problem only used turncounts, the allocation size was zero and thus threw a FILE_ERROR=194 for illegal storage access when attempting to redefine the turncount array.

Version 1.0.5

Version 1.0.5Fixed a bug where a section of code in the dynamic estimation routine was not thread safe, and could lead to substantially di?erent solutions when using NCORES > 1.

Version 1.0.3

Version 1.0.3Made change to use the high screenline number from the screenline file instead of the ICP file for static estimation. The HIGHSL value in the ICP file is actually the total number of independent screenlines present in the file and not the high value, so if there were gaps in screenline numbers this was not correct and caused an illegal storage access crash when running problems with gaps in the numbers, or those that started with an offset number.

Version 1.1.3

Version 1.1.3• Added new program parameter:

MPIWILD — Wildcard value for the drive name when doing an MPI run on a distributed memory cluster. This will allow all nodes employing MPI processes to share the same drive.

• Added new program options: MEMOPT1 — Perform level-1 memory optimizations for

dynamic estimation. Enabling this option allows the packet log file to be processed in memory which is substantially faster than file-based processing, but may require a large amount of memory.

MEMOPT2 — Perform level-2 memory optimizations for dynamic estimation. Enabling this option allows the Cube Analyst Drive program to use a faster algorithm for processing the route choice matrix, but requires a substantial amount of memory.

• Added new error codes: FILE_ERROR = 25 — Error reading the input warm start turn

choice matrix. FILE_ERROR = 26 — Insufficient memory to use

MEMOPT2=T option. The user should set MEMOPT2=F and try the estimation again.

FILE_ERROR = 29 — Error reading trip end file. FILE_ERROR = 107 — Cannot read PKTLNG value from

packet log file. FILE_ERROR = 124 — No nonzero screenline values in the

screenline file. FILE_ERROR = 203 — Registry Key Not Found.

• Updated system error code reporting: If the main program has a nonzero exit status from the system call, the program will report the Windows System Error code to the print file along with the Analyst Drive FILE_ERROR code of 199 (unexpected crash).

Version 1.1.3

• Enhancement to the parallelization scheme for dynamic estimation, leading to substantial performance improvements when using more than 3 cores on large problems

• Parameters TRIPWGHTI and TRIPWGHTIJ are now listed as TRWGHTI and TRWGHTJ in the documentation to correctly match the resource file. An error which caused the default values of 100 for each parameter to be incorrectly passed as 1 has been fixed. A typo in the resource file which listed TRWGHTI as TPWGHTI — and which would have prevented the TRWGHTI parameter from being passed correctly to the program — has also been fixed.

• The parameter MATWEIGHT is now correctly listed as MATWGHT in the documentation to match the resource file. Additionally, a typo in the resource file which incorrectly listed its default value as 1.0 has been corrected to reflect the true value of 0.1.

• A change in static estimation so it uses the high screenline number from the screenline file, instead of HIGHSL from the ICP file. HIGHSL is actually the total number of independent screenlines present in the file and not the high value, so if there are gaps in screenline numbers this was not correct.

• Fixed an error in the file-based packet log processor which incorrectly processed certain packets to indicate they matched a turn count set.

• An issue was found where the the gradient contribution from the trip end data was not properly factored; this has been corrected.

• Fixed an error in cost function evaluation. The function has been corrected to use the appropriate scaled or unscaled term depending on the program option. This fix could lead to solution changes from previous versions in all static estimation problems.

• Fix for a crash in multiclass estimation.

Version 1.1.3

• Fix for an error present when using both turning counts and screenline counts simultaneously in dynamic estimation, causing the turn choice matrix values to be half of their correct values.

• Fix for minor inconsistencies in Static Estimation outputs between 1 and 2+ cores

• Enhancements to print file: Added "Final" cost and RMSE after "Last Iteration" cost and

RMSE in the print file for clarification. The last iteration cost is not necessarily the final cost.

Added statements for static estimation describing the trip end and background term contributions to the cost function. This provides the user with a sense of scale when selecting the weighting parameters.

Version 1.0.2

Version 1.0.2Cube Analyst Drive 1.0.2 includes:

• A fix in dynamic estimation. Previously, packet weights in the packet log file less than 1 would be read as 0. These packet weights are now read correctly.

• Revision to format of General dynamic OD matrix file and General dynamic count file. See “General dynamic count files” on page 49. Each has a new column for the confidence value.

• The PREPSL option has been removed.

• Addition of FILE_ERROR codes 19, 92, 43, 44, 93, 106 and 190-195; removal of code 60. See “File error codes” on page 84.

• A program crash when using the GUI 'memory' button, causing the program to crash immediately, has been fixed

• MPI Fix for an MPI hang when there was an error reading the

control file by the master process. The error was not communicated to other processes and so the program 'terminated' but the cmd window stayed open indefinitely as the other processes waited for a signal.

Fix for an MPI error when reporting to the print file

• Fix for the CNTCONF option. Previously it was was always used in single class static estimation, even if not chosen.

• More specific reporting of system errors caught by the signal handler (and added system signal handles to the calling program as well)

• Added some more thorough checks for incorrect / missing data

Software updates can also be done from the Citilabs Web site (www.citilabs.com). Detailed instructions for Web-updating Cube Analyst Drive are available at www.citilabs.com. A current maintenance contract is required for web update.

WARNING: Do not attempt to update your software if your maintenance contract has expired, or you did not update the maintenance contract expiration date by re-installing from the replacement DVD. It will render your system inoperable.

From the Help menu, choose Check for Update to check for newer versions of the software on the Citilabs Web site. If a newer version is found, the program will display the version number and date of the new version. If your software has a current maintenance contract, the software will provide an option to go to the download page where you can download the latest version.

This program can also be set to automatically check for new updates once a month if an internet connection is available. This option can be turned on and off on the check update screen.
