Abstract

The aim of this study is to evaluate the noise and vibration level in the vehicle cockpit, while moving through the designed rumble strip. The motorcycle, passenger car, pick-up truck and heavy truck are selected as test vehicles. In order to assess the impact of driver awareness, it is considered the difference in noise and vibrations level within the cockpit while moving through the rumble strip. The results concluded that the noise level inside a cockpit, while the vehicle is moving through a rumble strip, increases according to the speed of the vehicle. On the other hand, the vibration level inside a cockpit tends to decrease, corresponding to the movement velocity. Taking into account the appropriate design for the rumble strip, each vehicle type is inconsistent. We found that the most appropriate rumble strip design for motorcycles is 10 cm wide and 0.3 cm thick, with 25 cm spacing between the stripes. Passenger cars are also 10 cm wide but 0.6 cm thick, and the spacing between the stripes remains 25 cm. The appropriate rumble strip design for pick-up trucks is the same as for passenger cars, but the spacing between the stripes is 50 cm. In the case of heavy trucks, the design is higher than others, with a width of 20 cm, a thickness of 0.6 cm, and a spacing of 50 cm between the stripes. The outcome enhances the advancement of knowledge in order to improve design requirements for ensuring safety at railway crossings, mitigating the likelihood of accidents, and optimizing the efficiency of the railway system.
