This paper aims to study the characteristics of greenhouse gas (GHG) emissions from heavy-duty trucks in the Beijing-Tianjin-Hebei (BTH) region, which is located in Northern China. The multiyear emissions of GHG (CO2, CH4 and N2O) from heavy-duty trucks fueled by diesel and natural gas during the period of 2006–2015 were compared and analyzed. The results show that the GHG emissions from heavy-...

Washing of trucks before leaving the abattoir is mandatory in the Republic of Ireland; however, little is known about the efficacy of the cleaning methods in use on trucks following the transportation of live pigs in Ireland. A National Salmonella Control Programme is in place in the Republic of Ireland, which requires the categorization of all pigs according to their Salmonella status. Herds i...

Nitrogen oxides (NOx) and black carbon (BC) emission factors (EF) of 440 on-road diesel trucks were determined by conducting on-road chasing studies in Beijing and Chongqing, China, in the winter 2010. NOx and BC EF distributions are reported. The median NOx EFs for trucks sampled on level roads in Chongqing and Beijing are 40.0 and 47.4 g kg-fuel 1, respectively. The median BC EFs are 1.1 and ...

Overall comparisons of crash rates based on mileage indicate that truck crash rates are lower than car crash rates, but that truck crashes are more severe. In 1978 the overall U.S. crash rate for cars was estimated at 8.2 accidents per million vehicle-miles of travel; for large trucks (including combinations) the rate was 4.7 per million vehicle-miles, and for combination trucks (e.g., tractor-...

Trucks account for one-fifth of transport sector emissions in Europe. To decarbonise, heavy-duty road freight must switch to zero-emission vehicles quickly. This report examines whether battery electric vehicles, systems and hydrogen fuel cell could compete with diesel-driven vehicles. It looks at the total cost ownership across nine different vehicle-size segments The gives six recommendations...

This paper presents experimental results of odometric accuracy tests obtained from the first production model of an innovative mobile robot called “OmniMate.” The OmniMate is an omnidirectional platform that comprises two individually controllable drive units (called “trucks”) that are physically connected by a compliant linkage. The compliant linkage allows relative motion between the two truc...
