    Abstract

    Purpose - In some developing countries, vehicles are often over-loaded, which causes road accidents and damage to road surfaces. Currently, large measuring facilities are used to measure the vehicle-loading on highways. A major limitation is that they can measure vehicle-loading at fixed locations only. This paper seeks to present an on-vehicle loading measurement system with capacitance and acceleration transducers. Design/methodology/approach - A description and analysis of the system are presented. Findings - The capacitance transducers sense the variation in distance between electrodes, using the on-vehicle leaf springs as weighing elastomers. The acceleration transducers deal with the influence of acceleration to vehicle-loading measurement. The major advantage of this system over the existing systems is that both static and dynamic loading can be measured. Practical implications - This system is simple and easy to install. Originality/value - The paper shows that with this system both a driver and an inspector can check vehicle-loading at any time and any location through radio communication, thus identifying over-loaded vehicles on highways. © Emerald Group Publishing Limited.
