The invention discloses a city road signal indicating lamp auxiliary system. The system comprises a pre-signal lamp arranged nearby a parking line of a crossroad and a vehicle sensor arranged between the parking line and the pre-signal lamp, and further comprises a time delay unit for adjusting the green-light time of a main signal lamp according to vehicle speed information acquired by the vehicle sensor. According to the invention, through arranging the pre-signal lamp and the green-light delay of the main signal lamp, a reliable auxiliary decision about whether a vehicle reaching the crossroad in yellow-light time can pass through the crossroad is provided, and the purposes of reducing the vehicle rear collision accident risky condition probability and ensuring the safety at the crossroad are achieved.
