1. Road user charging for heavy goods vehicles - Implementation aspects
Sammanfattning : Several factors have influenced the recent development in charging of heavy goods vehicles in Europe. European legislation is changed and the political will is strong in many countries. The public awareness and acceptance is large for the need to put a price and a cost on the use of infrastructure.

3. Improving emergency braking performance of heavy vehicles
Sammanfattning : Previous studies by the Cambridge Vehicle Dynamics Consortium (CVDC) have suggested that, by improving the control bandwidth of conventional Heavy Goods Vehicle(HGV) brake actuators and using a ‘slip control’ braking strategy, HGV stopping distances could be reduced by up to 30% over existing systems. The work covered in this thesis looks to: validate the CVDC’s previous braking performance predictions through Hardware-in-the-Loop (HiL) simulation, investigate how in-plane tyre dynamics may influence such a system’s performance, develop and build a next generation high-bandwidth braking system for vehicle implementation and carry out comparative back-to-back vehicle tests between the new system and commercially available HGV ABS.

4. Structural Interaction between Vehicles. An Investigation of Crash Compatibility between Cars and Heavy Goods Vehicles
Sammanfattning : While frontal collisions between Heavy Goods Vehicles (HGVs) and passenger cars are rarecompared to car-to-car frontal crashes, they are much more severe. Between 43% and 73% ofall frontal car-to-truck accidents result in fatalities. LÄS MER
5. A Holistic Safety Benefit Assessment Framework for Heavy Goods Vehicles
Sammanfattning : In 2019, more than one million crashes occurred on European roads, resulting in almost 23,000 traffic fatalities. Although heavy goods vehicles (HGVs) were only involved in 4.4% of these crashes, their proportion in crashes with fatal outcomes was almost three times larger. LÄS MER
