Abstract: Aiming at the current research on the signalized intersection delay calculation of GPS floating vehicles in city, a new method to estimate delay using the floating vehicle data is proposed to get rid of the traditional method. The delay process at signalized intersection is mainly analyzed, and the range and expedite travel speed of the signalized intersection is determined, which lays a foundation for determining the calculation process and calculation formula of the signalized intersection delay. At last, this method is validated based on the real data.
