The Traffic Engineering Division cannot say exactly how a signal was operating on a specific date and time due to field variables such as traffic demand. However, we can determine how a signal was programmed to operate, and if there were any malfunctions such as burned out light bulbs or power outages on a specific date.
Records of all programming changes and all maintenance responses are maintained at the Traffic Engineering Division. Requests for historical records concerning traffic operations should be referred to the Traffic Engineering Division. Requests must be made in writing on a Request for Documents form. All requests will be answered in 10 days. The Traffic Engineering Division does not interpret any timing sheets. To obtain a Request for Documents form, call the Traffic Engineering Division at 707-543-3814.
