Use of Hardware-in-the-Loop Traffic Simulation in a Virtual Environment

A recent assessment by the National Transportation Operations Collation revealed unsatisfactory performance of a number of traffic signal operation areas and an overall score of D- for the nation’s traffic signals. This poor rating affects commuters nationwide and contributes to traffic congestion. Numerous traffic simulation models have been developed to analyze more complex transportation facilities. However, these models may have some shortcomings in accurately modeling complex traffic signal controller functions (which could have a drastic effect on operations). Hardware-in-the-loop simulation (HILS), which replaces a simulation’s signal control logic with actual controller hardware, allows advanced signal functionality to be tested and analyzed. Moreover, this simulation process opens new research areas in traffic controller functionality. This paper discusses the development of a controller interface device (CID) by the Advanced Traffic Analysis Center (ATAC) to support HILS. This CID improves upon existing devices in a number of ways, including: it works with the VISSIM traffic simulation model, uses current off-the-shelf technology, more cost effective, easy to setup and use, small in size, and its Ethernet connectivity allows it to communicate with CIDs/controllers virtually anywhere in the world.
