Due to heightened security, your security officer has asked you for options that would control and monitor automobile traffic into the employee parking lot. Which of the following do you think would be a good option to recommend?

Trip lighting would only display the vehicle, but does not provide any control mechanism. A vehicle barrier would prevent the vehicle from entering. A Class I vehicular gate is for residential gate operation. A Class II vehicular gate is designed for commercial use, such as a parking lot or garage.
