Abstract: The purpose of this paper is to present a taxonomy of fuel use and pollutant emissions rates for heavy duty diesel (HDD) equipment to assist equipment managers in estimating the energy and environmental effects of their ...

Abstract: This paper provides a historical perspective on computing research in civil engineering, as reflected in the

Abstract: It is difficult to quantitatively assess the impact of engine idling on fuel use and emissions of construction equipment because of a lack of sufficient data. This paper presents a methodology for evaluating the impact of ...

Abstract: The objective of this paper is to present an improved paint pavement-marking retroreflectivity degradation model. Previous degradation-modeling methods were reviewed and studied. The paint-marking retroreflectivity data ...

Abstract: This paper addresses the impact of bead density on paint pavement marking retroreflectivity. The writers collected retroreflectivity data and glass bead images on 40 segments of two-lane highways. Bead density is defined ...
