It applied a modified regenerative vacuum sweeper and efficient washer to evaluate the effectiveness of sweeping. Effects of traffic volume and wind velocity on the sweeping efficiencies are also discussed in the paper. Dynamic PM10 variability was measured to evaluate of the sweeping effectiveness. It was found that the direct impact of sweeping on ambient PM10 concentration was shortly lived, lasting no more about 4-6 minutes. Effectiveness of sweeping for controlling ambient PM10 was evaluated by PM10 measurements and determining silt load from activities traffic streets. It did good job collecting the visible fine particles on roads, the method of sweeping tested was effective at removing the sources of the road dust particles. The sweeping efficiencies were obtained based on the experimental data of silt loading, PM10, and the relationship of the two efficiencies also can be expressed.
