Abstract

The invention relates to the technical field of tunnel lighting, and is a method for estimating the energy consumption of on-board lighting in a tunnel and the length of an optimal control section. The energy consumption estimation method comprises: obtaining geometric parameters of the tunnel, positions of lamps in the tunnel and historical traffic volume data; obtaining vehicle trajectory data based on the historical traffic volume data; establishing a one-dimensional coordinate system of the tunnel; and calculating the energy consumption of the tunnel within one day based on the one-dimensional coordinate system of the tunnel and the vehicle trajectory data. The energy consumption estimation method of the invention takes into account the distribution of historical traffic flow over time, so that the simulation scene is closer to reality and the energy consumption estimation result is more accurate. The energy consumption estimation method proposed by the invention can also evaluate the energy-saving effect under different control section lengths, thereby determining the optimal control section length, providing a more scientific basis for the intelligent lighting construction of the tunnel and maximizing the energy utilization.
