The present research investigates the influence of pavement distresses on traffic operational performance in terms speed and capacity. are expressed by condition index (PCI). Three roads multi-lane highways located road network Kafrelsheikh governorate, Egypt, were chosen as a case study. Road geometry, characteristics, volume collected manually from 23 sections for field data surveys. For meas...

Increasing attention is being paid to the energy efficiency in metro systems to reduce the operational cost and to advocate the sustainability of railway systems. Classical research has studied the energy-efficient operational strategy and the energy-efficient system design separately to reduce the traction energy consumption. This paper aims to combine the operational strategies and the system...

We investigate changes in operational performance that result from enterprise resource planning (ERP) system implementation. A literature-based and theory-driven model was developed to examine the relationship between ERP system implementation status and operational performance. Data were gathered through a field study to test the hypothesized relationships. The results indicate that the implem...

Background Wildfire simulators allow estimating fire spread and behaviour in complex environments, supporting planning analysis of incidents real time. However, uncertainty derived from input data quality model inherent inaccuracies may undermine the utility such predictions.Aims We assessed performance models for initial attack used California through rate (ROS) 1853 wildfires.Methods retrieve...
