Vehicle Payload Detection at Low Speeds through We

This proposal is aimed at the development of an innovative weigh-in-motion (WIM) sensor that uses purely fiber-optic sensing methods to remotely measure the weight and weight distribution of slow-moving vehicles. Specifically, an fiber Bragg grating based sensing system will be developed, in surface-mounted and in-ground configurations, that measures the axle and wheel weights of slow moving (<10 mph) passenger vehicles for stand-off detection of anomalously loaded sedans. Such a sensor system will be capable of accurately measuring the axle and wheel weights of slow moving passenger vehicles for determination of whether a vehicle carries a concealed payload, such as a vehicle-borne improvised explosive device (VBIED).
