Query: Sunlight Enabled Vehicle Detection by LED Street Lights   We propose and demonstrate a preliminary traffic sensing system based on the
widely distributed LED street lights. The system utilizes and discriminates the
photoelectric responses of the LEDs to sunlight when a vehicle moves through
the LEDs' field of view aiming at the road. A data vector is constructed from
the consecutively collected time samples of a moving observation window, and a
support vector machine (SVM) based learning algorithm is subsequently developed
to classify the presence of a vehicle. Finally, we build a simulated platform
to experimentally evaluate the performance of the vehicle detection algorithm.
