Road Assets Maintenance and Performance of Road Agencies in Kenya
International Journal of Research and Scientific InnovationAccording to Sustainable Development Goals (SDG) target 11.2, access to secure, affordable, accessible, and sustainable transport systems is to be provided by the year 2030. In addition, Kenya’s Vision 2030 aims to improve domestic and regional trade through the construction and rehabilitation of approximately 5,500 kilometers of roads, including 3,825

Performance of Off-road Vehicles
2016Vehicle performance refers to the science of motioning of the vehicle in terms of transient performance (e.g. acceleration, braking, cornering) and those of steady-state performance criteria such as (power driveline losses, gross and net traction, vehicle aerodynamics).

Performance indicators for the road sector
Transportation, 1999Seeing the trend for public accountability of road administrations and noting the many reform efforts undertaken in transport sectors around the world, the OECD established a Scientific Expert Group on Performance Indicators for the Road Sector in 1996 to provide its member countries a framework for assessing road administrations' performance.

Prediction of Road Marking Performance
Journal of Transportation Engineering, 2007From the road user's point of view the night-time visibility of road markings during wet conditions is of great importance, and instruments aimed for mobile measurement of the retroreflectivity of road markings are available. However, due to splash from the tires of the measuring vehicle, it is almost impossible to carry out measurements on wet road ...

Road Network Performance Measurements
2023Road Network Performance (RNP) impacts economic, ecological, and social sustainability. Nonetheless, models for road transport cost estimation often fail to account for the regional specificity of RNP. While the availability of suitable tools, data sources, and computational capacities to measure concrete RNP on a wide scale has steadily increased ...

THE PERFORMANCE OF ROAD IRONWORK INSTALLATIONS.
Proceedings of the Institution of Civil Engineers - Municipal Engineer, 1997The term 'road ironwork' is used to refer to covers that are placed over manholes, drainage gullies, water valves and similar installations in highways, which are common in urban areas. Highway engineers have to deal with a high incidence of premature failure in these installations, the total costs of which are estimated to be #207 million per year ...

Road Standards and Traffic Performance
Journal of Forestry, 1986The cost of constructing and maintaining transportation systems concerns foresters, public and private. In 1982, the USDA Forest Service budget for roads was $567 million. In 1985, the figure amounted to $613 million. A 1981 Forest Service directive called attention to problems arising because "roads are often built at too high a standard, which ...

An Assessment of the Belt and Road Performance
2019The aim of the chapter is to propose a methodology to illustrate the cost and time components of door-to-door movement by One Belt and One Road (OBOR) and traditional routes alongside with modes. The study is concentrated on a case study and uses established multimodal transport cost model as a research framework. Interviews with industry practitioners
