Microscopic　traffic　simulation　software　VISSIM　sets　up　a　simulated　traffic　intersection　environment,　and　exchanges　information　with　real　traffic　signal　controller.　The　controller　outputs　signals　to　regulate　vehicles　in　simulated　environment;　meanwhile,　VISSIM　detects　vehicle　information.　Detected　information　will　be　fed　back　to　the　controller.　Under　the　simultaneous　working　of　real　traffic　signal　controller　and　simulated　traffic　environment,　the　evaluation　of　vehicles　operation　in　simulated　intersection　can　be　done　through　the　evaluation　module　of　VISSIM.　Vehicles　operation　is　a　product　of　traffic　signal　controller.　Therefore,　based　on　hardware-in-the-loop,　it　is　possible　to　evaluate　and　test　the　effectiveness　of　control　strategy　of　traffic　signal　controller.
