Hardware and software design of an automated testing tool for traffic controllers

Traffic engineers and technicians are faced with the challenge of testing traffic controllers to ensure that they comply with the state requirements prior to deployment. Currently the test is being done manually using manual "suitcase testers". These manual based tests can be tedious and time consuming and come with many limitations such as the inability to document the results and hard to replicate field cases. This paper introduces development of an automated test tool and a new script language (CIDScript) for testing traffic signal controller functionality. The automation test tool can be used to replace or supplement manual testing
