Abstract

In a previous publication in this journal the framework for the development of a model for the road bump problem was laid. The current paper focuses on the aspect of determining the effective distance between two consecutive road bumps developing equations governing the velocity and the wavelength of the motion of the vehicle. The wave equation is re‐modelled connecting the isolation factor, linear velocity, wavelength and the frequency of motion of the vehicle over a road bump. A new set of equations is developed to extend the framework earlier presented in Salau et al. The feasibility of the model is demonstrated by its behaviour in graph and simulated data generation.

Summary

Introduction and literature review

Road bumps research has recently emerged as a new star in transportation studies. A new perspective taken by some researchers has been the design of road bumps in such a way to control excessive speeding with the use of some scientific indicators. In a related study Salau et al [8] presented a set of equations that would be useful in determining the effective distance between two road bumps in the control of vehicle speeds. While this study is original research in this direction, the use of a simplified velocity formula relating frequency to wavelength is significant limitation in the study This limitation arises as a result of the model inability to cope with complex situations demanding the application of more than one function in its computation. The isolation factor clearly stands as an important parameter used for this purpose Arising from this there is the application of the wave equation in calculating the effective distance between two road bumps. The wave equation is connected with the velocity, displacement frequency and wavelength time
