Influence of road conditions on the values of longitudinal acceleration during braking of a tourist coach

Abstract

The paper aims to analyse the longitudinal acceleration of a tourist coach on various road pavements. As part of the experimental research, braking tests were carried out at a speed of 30 km/h and acceleration to a speed of 30 km/h. The tests were carried out on four types of pavement, i.e. dry and wet asphalt and dry and wet concrete. The article describes the impact of road conditions on the braking and acceleration performance on selected road pavement types. To increase the reliability of the test results, ten tests were carried out for each tested pavement. Based on the test results, graphs of braking decelerations and accelerations during accelerating the vehicle as a function of time. This allowed for statistical analysis of the recorded decelerations and accelerations.

Experimental Study on Longitudinal Acceleration of Urban Buses and Coaches in Different Road Maneuvers

“…Many studies and scientific papers confirm that longitudinal acceleration is one of the factors that determine the comfort of passengers in urban buses and coaches. Papers [ 36 , 37 , 38 , 39 ] present the results of a study with the evaluation of acceleration values considered to be uncomfortable by seated standing and moving passengers on the bus, registered at different speeds and traffic conditions.…”
