Appendix O: File Extensions
The files used by TSIS tools have a fixed file naming convention. The convention is defined as follows:
file_name.???
where:
file_name is any standard file name. In many cases the file_name is the same name as the case.
.??? is the file extension. Many of the file extensions are listed below.
User Generated Files
INP – Contains a list of input file names and directory paths to be used in the run-many cases script.
PAT – Path data file used by CORSIM. The file_name is the case_name.
TCF – TSIS Configuration File. A file that defines a TSIS project and contains information about the project , e.g., project description and creator. The file_name is the project name.
TNO – Traffic Network Object file that contains the geometric, control, demand, and graphic data for the network. Created by TRAFED in XML format. The file_name is the case_name.
TRF – A file that contains the input data used to define a CORSIM network and to drive the CORSIM simulation for a single simulation case. Created by TRAFED or with a text editor. The file_name is the case_name.
TXT – A text file that can be created or edited with a text editor.
VBS – Visual Basic Script. A file that contains a Visual Basic script.
VEH – Probe vehicle injection data used by CORSIM when path following is requested. The file_name is the case_name.
TSIS Generated Files
CSV – Comma Separated Value file. Normally used as an input to a spreadsheet program. CORSIM creates the output data in CSV format. The Output Processor can also produce its results in CSV format. The file_name is the case_name.
LU? – Temporary file used during the execution of CORSIM. The file_name is the case_name.
OUT – Output file generated by CORSIM, which contains the results of the run including messages and MOE. The file_name is the case_name.
PRB – Probe vehicle file created by CORSIM to track vehicles injected via the path following capability of CORSIM. The file_name is the case_name.
TS? – Time Step Data file, created by the CORSIM driver. Contains the vehicle, incident and control data generated by CORSIM that is used by TRAFVU to animate the network. Each file has a maximum size of 2 gigabytes so in order to animate larger amounts of data, subsequent files are generated. TS0 is generated first, TS1 is generated next, TS2 is generated after that, and so on. The file_name is the case_name.
TSI – Time Step Index file, created by the CORSIM driver. Contains indexes into the TSD data files to allow moving through the TSD file efficiently. The file_name is the case_name.
TID – Time Interval Data file, created by the CORSIM driver. Contains the MOE data generated by CORSIM that is used by TRAFVU to display the network MOE. The file_name is the case_name.
TII – Time Interval Index file, created by the CORSIM driver. Contains indexes into the TID data file to allow moving through the TID file efficiently. The file_name is the case_name.
XLS – A Microsoft Excel spreadsheet file. The Output Processor can produce its results in Excel format. The file_name is the case_name plus an identifier to show the granularity of the data (e.g. _cumulative, _interval, _timeperiod).
TSIS Generated FIles
DLL – Dynamic-Link Library. In general, a DLL is a file that contains one or more functions that are compiled, linked, and stored separately from the processes that use them.
OCX – ActiveX control file. A component format used by the TSIS container.
