The multi-sensor and mechanical WIM systems were characterised. The assumption of the necessity of simultaneous analysis of vehicles types (by number of wheels, e.g. two-wheelers, four wheelers, etc.) participating in traffic, was made. This type of analysis involves not only the measurement of vehicle weight but also qualitative detection. Such data are mainly collected and analysed in urban traffic, in which information on traffic volume, lane occupancy or the number of vehicles waiting to enter an intersection are important to ensure continuous, smooth traffic flow. This article presents a design of a WIM system in which the detector is a beam with Bragg grating optical fibre sensors glued on it. Four cases of beam load were determined, due to its strength and the ability to register deformations. The strength analysis of the beam was carried out with the help of MES and its shape was optimised.

Abstract The service life of bridges is significantly affected by fatigue of used material induced by heavy vehicles. Therefore, precise determination of the vehicle weight is of crucial importance for the calculation of fatigue damage and the prediction of the bridge serviceability. This paper investigates accuracy of the determination of fatigue depending on the length of traffic flow recording. The presented data were obtained from the measurements carried out on a bridge of the Prague Highway Ring. The analysis reveals that the optimal length of traffic recording is about 30 days.
