Brake-Actuated Steering of Heavy Goods Vehicles
Large-scale adoption of higher capacity vehicles in road freight transport can significantly improve transport productivity and reduce fuel consumption and greenhouse gas emissions. To date, their adoption in the UK is limited by their reduced low-speed manoeuvrability. Active rear-steering …

A Cyclist Detection and Tracking System for Heavy Goods Vehicles
… A Cyclist Detection and Tracking System for Heavy Goods Vehicles Author: Yan KE Heavy Goods Vehicles (HGVs) contribute to a large portion of collisions with cyclists, and a disproportionate number of these are caused by construction vehicles. Among all these collisions, the sides-of-HGV …

An Experimental Investigation of Underbody and Near Wake Aerodynamics of Heavy Goods Vehicles
… strive to reduce the fuel consumption of Heavy Goods Vehicles (HGVs). At motorway speeds, fuel consumption is highly dependent on aerodynamic drag, a considerable proportion of which is attributed to the significantly less well documented trailer underbody. Moreover, the underbody flow …

An Investigation of Higher Capacity Urban Freight Vehicles
… have shown that increasing the capacity of Heavy Goods Vehicles is one of the most effective ways of reducing fuel consumption per tonne-kilometre of freight moved, with consequent reductions in greenhouse and noxious emissions. Some of the disadvantages of larger vehicles are more …

Development of a micro-simulation model for motorway roadworks with the use of narrow lanes and lane closure schemes
… parameters (e.g. flow rates, percentage of heavy goods vehicles, roadwork zone lengths and speed limits) has been tested. The reason for building this model from scratch is the inability of an industry standard software package (i.e. S-Paramics), which has been made available for this …

Advanced Braking Systems for Heavy Vehicles
… slip control algorithms on pneumatically braked heavy goods vehicles. Anti-lock braking systems (ABS) on commercial heavy vehicles use inefficient control approaches that work on cycles of exceeding the limits of tyre-road adhesion. Long pipe lengths and slow pneumatic brake valves create time …

Vision-Based Over-Height Vehicle Detection for Warning Drivers
… at a time when trucks and other large vehicles were smaller. A bridge or tunnel strike is an incidence in which a vehicle, typically a lorry (truck) or double-decker bus, tries to pass under a bridge or tunnel that is lower than its height, subsequently colliding with the structure. …

Modelling drivers’ behaviour within the dilemma zone at traffic signal junctions
… the effects of various parameters (such as heavy goods vehicles proportion HGVs%, intergreen length and installation of red light cameras) on drivers’ compliance with the traffic light signal change and junction capacity as well as vehicles’ delays. Based on existing traffic simulation …

Essays on Urban Economics
… charging scheme (CCZ) on the traffic by vehicles with different pollution intensities and ambient air quality within the Greater London Area. The implementation of such a policy effectively reduces the traffic flows from less-polluted vehicles, like private cars by roughly 16% inside …

Vision-based trailer pose estimation for articulated vehicles
Articulated Heavy Goods Vehicles (HGVs) are more efficient than conventional rigid lorries, but exhibit reduced low-speed manoeuvrability and high-speed stability. Technologies such as autonomous reversing and path-following trailer steering can mitigate this, but practical limitations of the …

Influence of accelerator pedal force feedback on truck drivers' speed control
… consumption and harmful exhaust emissions of Heavy Goods Vehicles (HGVs). Vehicle manufacturers and operators alike are having to investigate and find new ways of making reductions. It is thought that improving driver behaviour offers significant potential for these reductions in fuel …

A technical, economic, and environmental assessment of Power-to-X applications for heavy-duty transport
… sustainable ways to transport both people and goods is key to meeting ambitious emissions targets. The low energy density of current battery technology presents significant challenges for use in long-distance, heavy-duty transport. The Power-to-X concept converts electricity to hydrogen via …

Electrofuels in a circular economy
With the global shift away from traditional dispatchable fossil hydrocarbon fuels, the requirement for energy storage is of increasing importance. Renewable electricity generation is predominately in the form of variable renewable electricity, produced by wind and solar technologies. Intermittent …
