Interactive Traffic Signal System Laboratory at Purdue

The 1990's began a new direction in traffic signal control partly as a result of the 1991 Intermodal Surface Transportation Efficiency Act (ISTEA) and partly as the result of rapidly developing computer and communication technology.The advancements in the computer and communication fields provided the enabling technology that provided affordable computing platforms for developing improved traffic signal controllers and associated peripherals.We have reached the point where traffic signal systems are a very complex large scale distributed computing network that is expected to function under adverse conditions with little or no "down-time."Because of the complex system interactions, it is highly undesirable to train new engineers and technicians on the job, because of the severe impact mistakes can have during training.
