Controller Interface Device (CID)

The Controller Interface Device (CID) developed at ATAC supports hardware-in-the-loop simulation using the VISSIM traffic simulation model and NEMA-TS2 traffic controllers. A CORSIM interface is also being developed.

CORTools

CORTools is a set of tools developed by ATAC to use with the TSIS software package. CORTools consists of two pieces of software, CORSeed and COROut. CORSeed provides an easy way to generate seed files for performing multiple simulation runs with TSIS. COROut is an output processor which reads in the individual output files from each simulation run and compiles them allowing the user to easily extract the data that is needed and generate custom reports.

Permissive Period Calculator

The Permissive Period Calculator (PPC) is a utility developed by ATAC to perform permissive period and force-off calculations. The program provides the output values and graphical representation of the permissive windows. These values may be entered into traffic signal controllers as well as traffic simulation models.

TMCount

The TMCount utility was developed by ATAC to process turning movement volumes and display the information in an organized manner for traffic operation and transportation planning analyses. A template was designed in Microsoft Excel to be used with Autoscope software. The template provides a summary sheet with daily averages in 15-minute intervals for approach turning movement volumes, hourly intersection totals, and intersection daily totals.

VISSeed

VISSeed is a utility that was developed by ATAC and is used with VISSIM to conduct multiple simulation runs of a scenario with different random number seeds. VISSeed will simulate multiple runs of a simulation scenario and collect all the necessary output files. It allows users to start batches of simulations that can be run overnight saving time and money.
