A dust sampling system including a dust sampler and a vehicle on which the dust sampler is placed. The dust sampler has a suction unit, a cyclone, a dust collection container, and an air intake conduit. The suction unit draws in air containing dust particles. The cyclone centrifugally separates the dust particles from the drawn-in air. The cyclone has an air input port, a particle discharge end, and an air output port connected to the suction unit. A dust collection container is positioned underneath the cyclone to receive the separated dust particles from the cyclone. The air intake conduit has an air inlet and an air outlet connected to the air input port of the cyclone. The suction unit draws in the air containing the dust particles into the air inlet of the air intake conduit while the vehicle moves to collect samples of fugitive dust from a road.
